Disable All Touch Screen Interactions While Animation

问题

I wish to disable all the touch screen interactions while an animation is being displayed. I don't wish to use the setClickable() method on the buttons at the start or end of the animation because there are a large number of buttons. Any suggestions?

In your Activity, you can override onTouchEvent and always return true; to indicate you are handling the touch events.

You can find the documentation for that function there.

Edit Here is one way you can disable touch over the whole screen instead of handling every view one by one... First change your current layout like this:

<FrameLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

    < .... put your current layout here ... />

    <TouchBlackHoleView
        android:id="@+id/black_hole"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />
</FrameLayout>

And then define your custom view with something like this:

public class TouchBlackHoleView extends View {
    private boolean touch_disabled=true;
    @Override
    public boolean onTouchEvent(MotionEvent e) {
        return touch_disabled;
    }
    public disable_touch(boolean b) {
        touch_disabled=b;
    }
}

Then, in the activity, you can disable the touch with

(TouchBlackHoleView) black_hole = findViewById(R.id.black_hole);
black_hole.disable_touch(true);

And enable it back with

black_hole.disable_touch(false);

answer to this issue

for (int i = 1; i < layout.getChildCount(); i++) { TableRow row = (TableRow) layout.getChildAt(i); row.setClickable(false);

selected all the rows of the table layout which had all the views and disabled them

Easy way to implement that is add transaperent layout over it (add it in your xml fill parent height and width).

In the animation start: transaparentlayout.setClickable(true);

In the animation end: transaparentlayout.setClickable(false);

Eventually I took as a basic answer of @Matthieu and make it work such way. I decide to publish my answer because it take me maybe 30 min to understood why I got error.

XML

<...your path to this view and in the end --> .TouchBlackHoleView
    android:id="@+id/blackHole"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Class

public class TouchBlackHoleView extends View { private boolean touchDisable = false;

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

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

public TouchBlackHoleView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    return touchDisable;
}

public void disableTouch(boolean value){
    touchDisable = value;
}
}

Using

blackHole = (TouchBlackHoleView) findViewById(R.id.blackHole);
blackHole.disableTouch(true);

Enjoy
