how to use both Ontouch and Onclick for an ImageButton?

in my app, i want two things to happen.

  1. when i touch and drag the ImageButton, it should move along with my finger.

    i used OnTouchListener() for this and it works fine.

  2. when i click the ImageButton, it should close the activity.

    i used OnClickListener() for this and it also works fine.

So, here is my problem. whenever i move the ImageButton OnTouchListener is tirggered and the ImageButton moves, the OnClickListener is also triggered at the end when i am releasing the button from moving.

How to use ontouch and onclick listeners on the same button without interfering on each other?


Solution 1:

Try this, It may help you

No need to set onClick() method onTouch() will handle both the case.

package com.example.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.GestureDetector;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.ImageButton;

public class MainActivity extends Activity {
    private GestureDetector gestureDetector;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gestureDetector = new GestureDetector(this, new SingleTapConfirm());
        ImageButton imageButton = (ImageButton) findViewById(R.id.img);

        imageButton.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {

                if (gestureDetector.onTouchEvent(arg1)) {
                    // single tap
                    return true;
                } else {
                    // your code for move and drag
                }

                return false;
            }
        });

    }

    private class SingleTapConfirm extends SimpleOnGestureListener {

        @Override
        public boolean onSingleTapUp(MotionEvent event) {
            return true;
        }
    }

}

Solution 2:

To have Click Listener, DoubleClick Listener, OnLongPress Listener, Swipe Left, Swipe Right, Swipe Up, Swipe Down on Single View you need to setOnTouchListener. i.e,

view.setOnTouchListener(new OnSwipeTouchListener(MainActivity.this) {

            @Override
            public void onClick() {
                super.onClick();
                // your on click here
            }

            @Override
            public void onDoubleClick() {
                super.onDoubleClick();
                // your on onDoubleClick here
            }

            @Override
            public void onLongClick() {
                super.onLongClick();
                // your on onLongClick here
            }

            @Override
            public void onSwipeUp() {
                super.onSwipeUp();
                // your swipe up here
            }

            @Override
            public void onSwipeDown() {
                super.onSwipeDown();
                // your swipe down here.
            }

            @Override
            public void onSwipeLeft() {
                super.onSwipeLeft();
                // your swipe left here.
            }

            @Override
            public void onSwipeRight() {
                super.onSwipeRight();
                // your swipe right here.
            }
        });

}

For this you need OnSwipeTouchListener class that implements OnTouchListener.

public class OnSwipeTouchListener implements View.OnTouchListener {

private GestureDetector gestureDetector;

public OnSwipeTouchListener(Context c) {
    gestureDetector = new GestureDetector(c, new GestureListener());
}

public boolean onTouch(final View view, final MotionEvent motionEvent) {
    return gestureDetector.onTouchEvent(motionEvent);
}

private final class GestureListener extends GestureDetector.SimpleOnGestureListener {

    private static final int SWIPE_THRESHOLD = 100;
    private static final int SWIPE_VELOCITY_THRESHOLD = 100;

    @Override
    public boolean onDown(MotionEvent e) {
        return true;
    }

    @Override
    public boolean onSingleTapUp(MotionEvent e) {
        onClick();
        return super.onSingleTapUp(e);
    }

    @Override
    public boolean onDoubleTap(MotionEvent e) {
        onDoubleClick();
        return super.onDoubleTap(e);
    }

    @Override
    public void onLongPress(MotionEvent e) {
        onLongClick();
        super.onLongPress(e);
    }

    // Determines the fling velocity and then fires the appropriate swipe event accordingly
    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
        boolean result = false;
        try {
            float diffY = e2.getY() - e1.getY();
            float diffX = e2.getX() - e1.getX();
            if (Math.abs(diffX) > Math.abs(diffY)) {
                if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffX > 0) {
                        onSwipeRight();
                    } else {
                        onSwipeLeft();
                    }
                }
            } else {
                if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        onSwipeDown();
                    } else {
                        onSwipeUp();
                    }
                }
            }
        } catch (Exception exception) {
            exception.printStackTrace();
        }
        return result;
    }
}

public void onSwipeRight() {
}

public void onSwipeLeft() {
}

public void onSwipeUp() {
}

public void onSwipeDown() {
}

public void onClick() {

}

public void onDoubleClick() {

}

public void onLongClick() {

}
}

Solution 3:

The problem with onClick and OnTouch event is that the moment you Click(with the intention to Click) it assumes the event to be OnTouch thus OnClick is never interpreted. The work around

isMove = false;
case MotionEvent.ACTION_DOWN:
//Your stuff
isMove = false;
case MotionEvent.ACTION_UP:
if (!isMove || (Xdiff < 10 && Ydiff < 10 ) {
view.performClick; //The check for Xdiff <10 && YDiff< 10 because sometime elements moves a little
even when you just click it   
}
case MotionEvent.ACTION_MOVE:
isMove = true;
