利用 sendKeyDownUpSync 模擬使用者按下鍵盤。

	 public boolean KeyUP() {
		 Instrumentation m_Instrumentation = new Instrumentation();
		 m_Instrumentation.sendKeyDownUpSync( KeyEvent.KEYCODE_DPAD_UP );
		 return true;
	 }
	 
	 public boolean KeyDOWN() {
		 Instrumentation m_Instrumentation = new Instrumentation();
		 m_Instrumentation.sendKeyDownUpSync( KeyEvent.KEYCODE_DPAD_DOWN );
		 return true;
	 }
	 
	 public boolean KeyLEFT() {
		 Instrumentation m_Instrumentation = new Instrumentation();
		 m_Instrumentation.sendKeyDownUpSync( KeyEvent.KEYCODE_DPAD_LEFT );
		 return true;
	 }
	 
	 public boolean KeyRIGHT() {
		 Instrumentation m_Instrumentation = new Instrumentation();
		 m_Instrumentation.sendKeyDownUpSync( KeyEvent.KEYCODE_DPAD_RIGHT );
		 return true;
	 }
