在TextView中自动水平滚动的问题

Question

I wanted to implement automatically horizontal scroll for the situation if my Text is too long. It worked when the activity is empty without anything focus on. But when I tried implement this in an activity with chronometers, it's not working. I tested it out without chronometer it works. I tried to use setSelected(true) , it's not working also. Is there any way to solve this, I need the scrolling function with the chronometer. Any comments and answer would be appreciated.

ScrollTextView.class

public class ScrollingTextView extends TextView{

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

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

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

@Override
protected void onFocusChanged(boolean focused, int direction,
        Rect previouslyFocusedRect){
    if(focused){
        super.onFocusChanged(focused, direction, previouslyFocusedRect);
    }
}

@Override
public void onWindowFocusChanged(boolean focused){
    if(focused){
        super.onWindowFocusChanged(focused);
    }
}

@Override
public boolean isFocused(){
    return true;
}
}

TextView

<com.android.app.ScrollingTextView
    android:id="@+id/display_message"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:paddingLeft="10dp"
    android:paddingTop="10dp"
    android:singleLine="true"
    android:text="Display Message"
    android:textSize="18dp"
    android:textColor="#ffffff"
    android:ellipsize="marquee"
    android:scrollHorizontally="true"
    android:fadingEdge="horizontal"
    android:marqueeRepeatLimit="marquee_forever"
    android:focusableInTouchMode="true"/>

Answer 1

Add this in your XML

I've figured it out by myself.

android:focusable="true" 

& then try again.

Edit :

i face this problem

In my case this is the reason why Textview is not Scrolling is that,

i put a listview in above textview so the textview is not scrolling. so itried this one

set listview focusable is false

listview.setfocusable(false);

then it works the text was scrolling.

Try this, it may help you.

 <TextView android:id="@+id/textView" android:layout_width="fill_parent" android:layout_height="wrap_content" android:clickable="true" android:onClick="onClick" android:smoothScrollbar="true" android:scrollbars="vertical" android:maxLines="6" android:ellipsize="none" android:scrollHorizontally="false" android:singleLine="false" />
