Stop listening for more listener events

android, event-listener, listener

Solution

You can remove the `OnGlobalLayoutListener` using the following code. There will still be a `strikethrough` on `removeGlobalOnLayoutListener()`, which has been deprecated. But, the lint warning will be taken care of by using the annotations.

@SuppressWarnings("deprecation")
@SuppressLint("NewApi")
searchWebView.getViewTreeObserver().addOnGlobalLayoutListener(
                    new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {

        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) {
                searchWebView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            } else {
                searchWebView.getViewTreeObserver().removeGlobalOnLayoutListener(this);
            }

    }
});

Problem

I listen to `onGlobalLayoutListener` as shown in below code. I want to listen it only once. Once `onGlobalLayout()` is called I want to stop listening to it. I tried using `removeOnGlobalLayoutListener()` method but that gives warning that call required API level 16 (current min is 14). I also tried using `removeGlobalOnLayoutListener`. But it is deprecated. Code : ``` searchWebView.getViewTreeObserver().addOnGlobalLayoutListener( new OnGlobalLayoutListener() { @Override public void onGlobalLayout() { // Do something // Remove listener } }); ``` How to remove `onGlobalLayoutListener`?
