Uiautomator Click On A Imagebutton With No Text Or Content-desc

On 4.2.2 emulator, in Now Playing screen from Music, we have the prev, play and next ImageButtons. Unfortunately these 3 buttons have no text or contet-desc values. I want to click

Solution 1:

In situations like this, I click by bounds. This is can cause problems cause when you change device sizes, the bounds will change. So I get the screen height so you know which device your using, then click by bounds. You can find your bounds via uiautomatorviewer

int height = UiDevice.getInstance().getDisplayHeight();

if(height == THE_SIZE_EXPECTED){
  UiDevice.getInstance().click(int_x, int_y);
 } elseif (height == ANOTHER_SCREEN_HEIGHT_OPTION){ 
   UiDevice.getInstance().click(int_x, int_y);
 } 

Hope this helps
