AppWidgetHostView can't handle onClick/onLongClick properly

Question

I am developing a launcher, now I am working with app widgets, I follow the tutorial from here: AppWigetHost tutrial - Leonardo Fischer Everything goes well until I tried a

Answer 1

after some days without any answer from SO, I tried to read the source code of Trebuchet-launcher It turns out very simple: extends the AppWidgetHostView and override the method onInterceptTouchEvent() like this source code - I haven't tried it yet, but I guess it will work :).

Hope this helps anyone like me :)

Answer 2

I encountered the same problem,I solved it by overwriting the method

ViewGroup#onInterceptTouchEvent(MotionEvent ev).

See "Managing Touch Events in a ViewGroup" for detail.

Answer 3

Hungson175's answer was great but it didn't get me there all the way. Since I'm using AppWidgetHost to create the AppWidgetHostView's I needed to extend both AppWidgetHost, and AppWidgetHostView. Luckily this is fairly simple to do and doesn't require too much overriding of default android methods.

WidgetHost

public class WidgetHost extends AppWidgetHost {

    public WidgetHost(Context context, int hostId) {
        super(context, hostId);
    }

    @Override
    protected AppWidgetHostView onCreateView(Context context, int appWidgetId, AppWidgetProviderInfo appWidget) {
        // pass back our custom AppWidgetHostView
        return new WidgetView(context);
    }
}

WidgetView

public class WidgetView extends AppWidgetHostView {

    private OnLongClickListener longClick;
    private long down;

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

    public WidgetView(Context context, int animationIn, int animationOut) {
        super(context, animationIn, animationOut);
    }

    @Override
    public void setOnLongClickListener(OnLongClickListener l) {
        this.longClick = l;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        switch(MotionEventCompat.getActionMasked( ev ) ) {
            case MotionEvent.ACTION_DOWN:
                down = System.currentTimeMillis();
                break;
            case MotionEvent.ACTION_MOVE:
                boolean upVal = System.currentTimeMillis() - down > 300L;
                if( upVal ) {
                    longClick.onLongClick( WidgetView.this );
                }
                break;
        }

        return false;
    }
}

Hope it helps someone, because dealing with AppWidget's is difficult enough.
