Resolution / Answer

Query key state of Blue - Orange - Shift Key

Customer can simulate a keypress to capture the keystate if using a Full Screen application using an OnCreate

1. The key code for orange and blue and shift is below(as per MC33 ) 

public static final int KEYCODE_SYMBOL_BLUE = 10027; 

public static final int KEYCODE_SYMBOL_ORANGE = 10028; 

public static final int KEYCODE_SYMBOL_SHIFT = 10032;

2. Customer can override Android API onKeyDown to access orange key or Blue key press in their application. Below is the code snippet example :- 


public boolean onKeyDown(int keyCode, KeyEvent event) { 

Log.d(TAG, "onKeyDown: Keycode: "+keyCode+" KeyEvent: "+event); 


Toast.makeText(this, "KeyName:KEYCODE_SYMBOL_ORANGE pressed!!!", Toast.LENGTH_SHORT).show(); 

}else if(KEYCODE_SYMBOL_BLUE == keyCode){ 

Toast.makeText(this, "KeyName:KEYCODE_SYMBOL_BLUE pressed!!!", Toast.LENGTH_SHORT).show(); 


return super.onKeyDown(keyCode, event);
