Android Drag and drop of button

Question

I am working in android, I am using a button. Now I want to perform drag and drop of this button.

This is my main.xml

Answer 1

I resolved my problem like this.

    @Override
     public boolean onTouch(View view, MotionEvent me) {
    if (me.getAction() == MotionEvent.ACTION_DOWN) {
        status = START_DRAGGING;


    }
    if (me.getAction() == MotionEvent.ACTION_UP) {
        status = STOP_DRAGGING;
        Log.i("Drag", "Stopped Dragging");
    } else if (me.getAction() == MotionEvent.ACTION_MOVE) {
        if (status == START_DRAGGING) {
            System.out.println("Dragging");

            LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
                    50, 50);
            layoutParams.setMargins((int) me.getRawX() - 25,
                    (int) me.getRawY() - 50, 0, 0);
            layout.removeView(btn);
            layout.addView(btn, layoutParams);

            btn.invalidate();
        }
    }
    return false;
}

Now its working fine.

Answer 2

you should get button's layout params, set left, right, top, bottom and set these layout params back to button

Answer 3

Try returning true from onTouch() method. That might work out. In one of my app it worked as return false was not moving the view as per my touch movement but return true statement solved it.
