ListView: TextView with LinkMovementMethod makes list item unclickable?

Question

What I want to do: A list with messages like this:

<UserName> and here is the mnessage the user writes, that will wrap nicely to the next line. exactly like this.

What I have:

ListView R.layout.list_item:

<TextView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/text_message"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="(Message Text)" />

Adapter that inflates the above layout and does:

SpannableStringBuilder f = new SpannableStringBuilder(check.getContent());
f.append(username);
f.setSpan(new InternalURLSpan(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Toast.makeText(context, "Clicked User", Toast.LENGTH_SHORT).show();
    }
}), f.length() - username.length(), f.length(),
        Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

f.append(" " + message);

messageTextView.setText(f);
messageTextView.setMovementMethod(LinkMovementMethod.getInstance());
meesageTextView.setFocusable(false);

The InternalURLSpan class

public class InternalURLSpan extends ClickableSpan {
    OnClickListener mListener;

    public InternalURLSpan(OnClickListener listener) {
        mListener = listener;
    }

    @Override
    public void onClick(View widget) {
        mListener.onClick(widget);
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        super.updateDrawState(ds);
        ds.setUnderlineText(false);
    }
}

In the activity I have in onCreate(...) :

listView.setOnItemClickListener(ProgramChecksActivity.this);

and the implementation of the above

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
    Toast.makeText(context, "Clicked Item", Toast.LENGTH_SHORT).show();
}

The problem:

Clicking on the item, does not show the toast. Only clicking on the username does show the toast.

I am guessing, that setMovementMethod(LinkMovementMethod.getInstance()); makes the TextView clickable. So the items themselves do never get clicked anymore.

How can I make the items clickable again? Having the same functionality as I want.

Answer 1

There are THREE show-stoppers in this situation. The root reason is that when you call setMovementMethod or setKeyListener , TextView "fixes" it's settings:

setFocusable(true);
setClickable(true);
setLongClickable(true);

The first problem is that when a View is clickable - it always consumes ACTION_UP event (it returns true in onTouchEvent(MotionEvent event) ).
To fix that you should return true in that method only if the user actually clicks the URL.

But the LinkMovementMethod doesn't tell us, if the user actually clicked a link. It returns "true" in it's onTouch if the user clicks the link, but also in many other cases.

So, actually I did a trick here:

public class TextViewFixTouchConsume extends TextView {

    boolean dontConsumeNonUrlClicks = true;
    boolean linkHit;

    public TextViewFixTouchConsume(Context context) {
        super(context);
    }

    public TextViewFixTouchConsume(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public TextViewFixTouchConsume(
        Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        linkHit = false;
        boolean res = super.onTouchEvent(event);

        if (dontConsumeNonUrlClicks)
            return linkHit;
        return res;

    }

    public void setTextViewHTML(String html)
    {
        CharSequence sequence = Html.fromHtml(html);
        SpannableStringBuilder strBuilder = 
            new SpannableStringBuilder(sequence);
        setText(strBuilder);
    }

    public static class LocalLinkMovementMethod extends LinkMovementMethod{
        static LocalLinkMovementMethod sInstance;


        public static LocalLinkMovementMethod getInstance() {
            if (sInstance == null)
                sInstance = new LocalLinkMovementMethod();

            return sInstance;
        }

        @Override
        public boolean onTouchEvent(TextView widget, 
            Spannable buffer, MotionEvent event) {
            int action = event.getAction();

            if (action == MotionEvent.ACTION_UP ||
                    action == MotionEvent.ACTION_DOWN) {
                int x = (int) event.getX();
                int y = (int) event.getY();

                x -= widget.getTotalPaddingLeft();
                y -= widget.getTotalPaddingTop();

                x += widget.getScrollX();
                y += widget.getScrollY();

                Layout layout = widget.getLayout();
                int line = layout.getLineForVertical(y);
                int off = layout.getOffsetForHorizontal(line, x);

                ClickableSpan[] link = buffer.getSpans(
                    off, off, ClickableSpan.class);

                if (link.length != 0) {
                    if (action == MotionEvent.ACTION_UP) {
                        link[0].onClick(widget);
                    } else if (action == MotionEvent.ACTION_DOWN) {
                        Selection.setSelection(buffer,
                                buffer.getSpanStart(link[0]),
                                buffer.getSpanEnd(link[0]));
                    }

                    if (widget instanceof TextViewFixTouchConsume){
                        ((TextViewFixTouchConsume) widget).linkHit = true;
                    }
                    return true;
                } else {
                    Selection.removeSelection(buffer);
                    Touch.onTouchEvent(widget, buffer, event);
                    return false;
                }
            }
            return Touch.onTouchEvent(widget, buffer, event);
        }
    }
}

You should call somewhere

textView.setMovementMethod(
    TextViewFixTouchConsume.LocalLinkMovementMethod.getInstance()
);

to set this MovementMethod for the textView.

This MovementMethod raises a flag in TextViewFixTouchConsume if user actually hits link. (only in ACTION_UP and ACTION_DOWN events) and TextViewFixTouchConsume.onTouchEvent returns true only if user actually hit link.

But that's not all!!!! The third problem is that ListView ( AbsListView ) calls it's performClick method (that calls onItemClick event handler) ONLY if ListView 's item view has no focusables. So, you need to override

@Override
public boolean hasFocusable() {
    return false;
}

in a view that you add to ListView . (in my case that is a layout that contains textView)

or you can use setOnClickLIstener for that view. The trick is not very good, but it works.

Answer 2

babay's answer is very nice. But if you don't want to subclass TextView and don't care about LinkMovementMethod features other than clicking on links you could use this approach (this is basically copying LinkMovementMethod's onTouch functionality into TextView's OnTouchListener):

        myTextView.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                boolean ret = false;
                CharSequence text = ((TextView) v).getText();
                Spannable stext = Spannable.Factory.getInstance().newSpannable(text);
                TextView widget = (TextView) v;
                int action = event.getAction();

                if (action == MotionEvent.ACTION_UP ||
                        action == MotionEvent.ACTION_DOWN) {
                    int x = (int) event.getX();
                    int y = (int) event.getY();

                    x -= widget.getTotalPaddingLeft();
                    y -= widget.getTotalPaddingTop();

                    x += widget.getScrollX();
                    y += widget.getScrollY();

                    Layout layout = widget.getLayout();
                    int line = layout.getLineForVertical(y);
                    int off = layout.getOffsetForHorizontal(line, x);

                    ClickableSpan[] link = stext.getSpans(off, off, ClickableSpan.class);

                    if (link.length != 0) {
                        if (action == MotionEvent.ACTION_UP) {
                            link[0].onClick(widget);
                        }
                        ret = true;
                    }
                }
                return ret;
            }
        });

Just assign this listener to your TextView in your list adapter getView() method.

Answer 3

Here is quick fix that makes ListView items and TextView UrlSpans clickable:

   private class YourListadapter extends BaseAdapter {

       @Override
       public View getView(int position, View convertView, ViewGroup parent) {
           ((ViewGroup)convertView).setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);

           return convertView
       }

    }

Answer 4

The problem is in that LinkMovementMethod indicates that are going to manage the touch event, independiently the touch is in a Spannable or in normal text.

This should work.

public class HtmlTextView extends TextView {

    ...

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (getMovementMethod() == null ) {
            boolean result = super.onTouchEvent(event); 
            return result;
        }

        MovementMethod m = getMovementMethod();     
        setMovementMethod(null);

        boolean mt = m.onTouchEvent(this, (Spannable) getText(), event);
        if (mt && event.getAction() == MotionEvent.ACTION_DOWN) {
            event.setAction(MotionEvent.ACTION_UP);
            mt = m.onTouchEvent(this, (Spannable) getText(), event);
            event.setAction(MotionEvent.ACTION_DOWN);
        }

        boolean st = super.onTouchEvent(event);

        setMovementMethod(m);
        setFocusable(false);

        return mt || st;
    }

    ...
}

Answer 5

This is happened because when we press on list item it sends the press event to all its children, so the child's setPressed calls rather than the list item. Hence for clicking the list item, you have to set the child's setPressed to false. For this, you have to make custom TextView class and override the desired method. Here is the sample code

public class DontPressWithParentTextView extends TextView {

public DontPressWithParentTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
public void setPressed(boolean pressed) {
    // If the parent is pressed, do not set to pressed.
    if (pressed && ((View) getParent()).isPressed()) {
        return;
    }
    super.setPressed(pressed);
}

}

Answer 6

I have another solution use the list item layout with two different text:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent" >

<com.me.test.DontPressWithParentTextView
    android:id="@+id/text_user"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:text="(Message Text)" />

<TextView
    android:id="@+id/text_message"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:text="(Message Text)" />

and the adapter code as:

DontPressWithParentTextView text1 =  (DontPressWithParentTextView) convertView.findViewById(R.id.text_user);

                TextView text2 = (TextView) convertView.findViewById(R.id.text_message);
                text2.setText(message);

                SpannableStringBuilder f = new SpannableStringBuilder();
                CharSequence username = names1[position];
                f.append(username );
                f.setSpan(new InternalURLSpan(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Toast.makeText(getBaseContext(), "Clicked User", Toast.LENGTH_SHORT).show();
                    }
                }), f.length() - username.length(), f.length(),
                        Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

                f.append(" ");

                text1.setText(f);
                text1.setMovementMethod(LinkMovementMethod.getInstance());
                text1.setFocusable(false);

This will work.. :-)

Answer 7

For all who interessted to do that with EmojisTextView from what @babay said in the fist answer i make some chages like that:

public class EmojiconTextView extends TextView {
private int mEmojiconSize;
private int mTextStart = 0;
private int mTextLength = -1;

boolean dontConsumeNonUrlClicks = true;
boolean linkHit;

public EmojiconTextView(Context context) {
    super(context);
    init(null);
}

public EmojiconTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init(attrs);
}

public EmojiconTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init(attrs);
}

private void init(AttributeSet attrs) {
    if (attrs == null) {
        mEmojiconSize = (int) getTextSize();
    } else {
        TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.Emojicon);
        mEmojiconSize = (int) a.getDimension(R.styleable.Emojicon_emojiconSize, getTextSize());
        mTextStart = a.getInteger(R.styleable.Emojicon_emojiconTextStart, 0);
        mTextLength = a.getInteger(R.styleable.Emojicon_emojiconTextLength, -1);
        a.recycle();
    }
    setText(getText());
}

@Override
public void setText(CharSequence text, BufferType type) {
    SpannableStringBuilder builder = new SpannableStringBuilder(text);
    EmojiconHandler.addEmojis(getContext(), builder, mEmojiconSize, mTextStart, mTextLength);
    super.setText(builder, type);
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    linkHit = false;
    boolean res = super.onTouchEvent(event);

    if (dontConsumeNonUrlClicks)
        return linkHit;
    return res;

}






/**
 * Set the size of emojicon in pixels.
 */
public void setEmojiconSize(int pixels) {
    mEmojiconSize = pixels;
}


public static class LocalLinkMovementMethod extends LinkMovementMethod {
    static LocalLinkMovementMethod sInstance;


    public static LocalLinkMovementMethod getInstance() {
        if (sInstance == null)
            sInstance = new LocalLinkMovementMethod();

        return sInstance;
    }

    @Override
    public boolean onTouchEvent(TextView widget,
                                Spannable buffer, MotionEvent event) {
        int action = event.getAction();

        if (action == MotionEvent.ACTION_UP ||
                action == MotionEvent.ACTION_DOWN) {
            int x = (int) event.getX();
            int y = (int) event.getY();

            x -= widget.getTotalPaddingLeft();
            y -= widget.getTotalPaddingTop();

            x += widget.getScrollX();
            y += widget.getScrollY();

            Layout layout = widget.getLayout();
            int line = layout.getLineForVertical(y);
            int off = layout.getOffsetForHorizontal(line, x);

            ClickableSpan[] link = buffer.getSpans(
                    off, off, ClickableSpan.class);

            if (link.length != 0) {
                if (action == MotionEvent.ACTION_UP) {
                    link[0].onClick(widget);
                } else if (action == MotionEvent.ACTION_DOWN) {
                    Selection.setSelection(buffer,
                            buffer.getSpanStart(link[0]),
                            buffer.getSpanEnd(link[0]));
                }

                if (widget instanceof EmojiconTextView){
                    ((EmojiconTextView) widget).linkHit = true;
                }
                return true;
            } else {
                Selection.removeSelection(buffer);
                Touch.onTouchEvent(widget, buffer, event);
                return false;
            }
        }
        return Touch.onTouchEvent(widget, buffer, event);
    }
}

}

after that you just do the same here:

yourTextView.setMovementMethod(EmojiconTextView.LocalLinkMovementMethod.getInstance());

Answer 8

apply this textview in layout. https://gist.github.com/amilcar-andrade/e4b76840da1dc92febfc

Answer 9

你必须把这一行放在你的适配器项父视图android:descendantFocusability="blocksDescendants"

Answer 10

Why do you use ListView.setOnItemClickListener() ? You can provide the same in adapter by messageTextView.setOnClickListener() .

Another method - set second clickable span for message - and provide actions there. If you don't want second part looks like a linke create

public class InternalClickableSpan extends ClickableSpan {
    OnClickListener mListener;

    public InternalClickableSpan(OnClickListener listener) {
        mListener = listener;
    }

    @Override
    public void onClick(View widget) {
        mListener.onClick(widget);
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        super.updateDrawState(ds);
        ds.setUnderlineText(false);
        ds.setColor(Color.WHITE);// Here you can provide any color - take it from resources or from theme.
    }
}

Answer 11

well,@babay's answer is right,but he seems had forgot something, you should write "TextViewFixTouchConsume" instead of "TextView" in xml, and then it will be work! for example :

<com.gongchang.buyer.widget.TextViewFixTouchConsume xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/wx_comment_friendsname"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/comment_bg_with_grey_selector"
android:lineSpacingExtra="1dp"
android:paddingBottom="1dp"
android:paddingLeft="@dimen/spacing_third"
android:paddingRight="@dimen/spacing_third"
android:paddingTop="1dp"
android:textColor="@color/text_black_2d"
android:textSize="@dimen/content_second" />
