I am creating a custom UI component where user can upload an image of a map and then user can specify certain locations and Display a pin. First upon image of the map loaded user will be able to pan and zoom to any position. for this I used following example which works like a charm. TouchImageView
Next part was to add a pin when it is long pressed on the image. For this I used an Absolute Layout over the map image and added an OnTouchListener and Returned false at the end for the touch listener on ImageView to work as well. I implemented the OnTouchListener As below
absoluteLayout.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, final MotionEvent event) {
switch (event.getAction()){
case MotionEvent.ACTION_DOWN:
count=-1;// reset count. Thredd will start as 0
released = false;// Touch long press is started
final Handler handler = new Handler();
new Thread(new Runnable() {
@Override
public void run() {
while(!released){//Stop count if touch released
try {
count++;// Count every 200 ms
Thread.sleep(200);
if(count>10){ //if pressed for 200*10= 2 seconds
released=true;
handler.post(new Runnable() {
@Override
public void run() {
addPin((int) event.getX(), (int) event.getY());//Calling the method to add the pin
}
});
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
break;
case MotionEvent.ACTION_UP:
released=true;// touch is released
break;
case MotionEvent.ACTION_MOVE:
released=true; // touch is a movement therefore release long press
break;
}
return false;
}
});
But the issue here is With case :"MotionEvent.ACTION_MOVE" it always make the long press released. But without it if user is trying to pan or zoom the imageView it will add a pin.
How can i detect if there is a movement in the touch and ignore when user is zooming or panning the map?
Thanks in advance.
