How to get a continuous Touch Event?

You need to set this properties for the element android:focusable="true" android:clickable="true" if not, just produce the down action.


Her is the simple code snippet which shows that how you can handle the continues touch event. When you touch the device and hold the touch and move your finder, the Touch Move action performed.

@Override
public boolean onTouchEvent(MotionEvent event) {
    float x = event.getX();
    float y = event.getY();
    if(isTsunami){
    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
            // Write your code to perform an action on down
            break;
        case MotionEvent.ACTION_MOVE:
            // Write your code to perform an action on contineus touch move
            break;
        case MotionEvent.ACTION_UP:
            // Write your code to perform an action on touch up
            break;
    }
    }
    return true;
}

Try this. It works to me:

public static OnTouchListener loadContainerOnTouchListener() {
    OnTouchListener listener = new OnTouchListener(){
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        LinearLayout layout = (LinearLayout)v;
        for(int i =0; i< layout.getChildCount(); i++)
        {
            View view = layout.getChildAt(i);
            Rect outRect = new Rect(view.getLeft(), view.getTop(), view.getRight(), view.getBottom());
            if(outRect.contains((int)event.getX(), (int)event.getY()))
            {
                Log.d(this.getClass().getName(), String.format("Over view.id[%d]", view.getId()));
            }
        }

    }

Remember: the listener you´ll set must be a container layout (Grid, Relative, Linear).

LinearLayout layout = findViewById(R.id.yourlayoutid);
layout.setOnTouchListener(HelperClass.loadContainerOnTouchListener());

Use if(me.getAction() == MotionEvent.ACTION_MOVE). It's impossible to keep a finger 100% completely still on the screen so Action_Move will get called every time the finger moves, even if it's only a pixel or two.

You could also listen for me.getAction() == MotionEvent.ACTION_UP - until that happens, the user must still have their finger on the screen.
