Android textview 中的多个可点击字符串

Question

I am creating a small Android app. I would like to display a text in a textview with multiple parts to click on. (Each should show some different message)

Finally I managed to find out how to display mutiple spans in one textview, however unfortunately the onClick methods don't work. Simply nothing happens, not even a logcat line.

I have something like this:

SpannableStringBuilder ssb=new SpannableStringBuilder();
ssb.append("first  second")

ssb.setSpan(new ClickableSpan() {
    @Override
    public void onClick(View v) {
    //Eredmeny2.this is just the context, name of the whole class
    Toast.makeText(Eredmeny2.this, "first", Toast.LENGTH_LONG).show();
    }
}, 1, 3, 0);

ssb.setSpan(new ClickableSpan() {
    @Override
    public void onClick(View v) {
    Toast.makeText(Eredmeny2.this, "second", Toast.LENGTH_LONG).show();
    }
}, 7, 10, 0);

TextView t1=new TextView(this);
t1.setText(ssb);
...

The text is underlined fine, but nothing happens when i click them. It is a part of a TableView, although I do not think this is relevant. Do you have any ideas why it does not do anything? What do I miss? Or should I do it on some totally different way?

Thanks in advance.

The layout file this part would use is the following:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
    android:id="@+id/ScrollView01"
    android:background="#FF0000">


    <TableLayout
        android:id="@+id/TableLayout01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:stretchColumns="0"
        android:showDividers="middle"
        android:padding="3dp">
    <TableRow
        android:id="@+id/TableRow01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <TextView
            android:id="@+id/TextView01"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginRight="3dp"
            android:background="#000000"
            android:textColor="#FFFFFF"
            android:padding="6dp"
            android:text="Hour"
            android:textSize="20sp"
            android:textStyle="bold" >

        </TextView>
        <TextView android:id="@+id/TextView02"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:textStyle="bold"
            android:text="Minute"
            android:padding="6dp"
            android:textColor="#FFFFFF"
            android:background="#000000">
        </TextView>

    </TableRow>

    </TableLayout>


</ScrollView>

And the TextView layout that the TextView uses directly is the following:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tv" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp"
android:background="#000000"
android:textIsSelectable="false"
android:textColor="#FFFFFF">
</TextView>

Answer 1

as i understand you want to make multiple part of textview clickable.

this code worked for me!

SpannableString ss = new SpannableString("this is a text");
ss.setSpan(new myClickableSpan(1),0, 4, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new myClickableSpan(2),5, 7, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new myClickableSpan(3),8, 10, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

mTextView.setText(ss);
mTextView.setMovementMethod(LinkMovementMethod.getInstance());

just make custom ClickableSpan to handle the click event

public class myClickableSpan extends ClickableSpan{

    int pos;
    public myClickableSpan(int position){
        this.pos=position;
    }

    @Override
    public void onClick(View widget) {
        Toast.makeText(getApplicationContext(), "Position "  + pos + " clicked!", Toast.LENGTH_LONG).show();
    }

}

Answer 2

it's rather old, but I just encounter this situation too.

For me I use difference clickable span for two or more clickable text in Text View. So to saving time I declare it by using List in Kotlin.

Here is the code.

val listClickSpan = List<ClickableSpan>(2) {
    object : ClickableSpan() {
        override fun onClick(widget: View) {
            startActivity(Intent(mContext, SomeActivity::class.java))
        }

        override fun updateDrawState(ds: TextPaint) {
            super.updateDrawState(ds)
            ds.isUnderlineText = false
            ds.color = ContextCompat.getColor(mContext, R.color.dark_blue)
        }
    }
}

val font = ResourcesCompat.getFont(mContext, R.font.roboto_bold)
SpannableString(mContext.getString(R.string.multiple_text)).apply {
    if (font != null)
        setSpan(
            CustomTypefaceSpan(font), 67, 83, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
        )
    setSpan(listClickSpan[0], 67, 83, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
    if (font != null)
        setSpan(
            CustomTypefaceSpan(font), 88, 105, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
        )
    setSpan(listClickSpan[1], 88, 105, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
    bind.tvLink.setText(this, TextView.BufferType.SPANNABLE)
    bind.tvLink.movementMethod = LinkMovementMethod.getInstance()
    bind.tvLink.linksClickable = true
}

Hope it will help you
