通过uiautomatorbrider来调用inject事件

public static boolean longPressKeyCode(int keyCode,int PressTime) {
          try {
               Field mUiAutomationBridge = Class.forName("com.android.uiautomator.core.UiDevice").getDeclaredField("mUiAutomationBridge"); 
               mUiAutomationBridge.setAccessible(true); 
    
               Object bridgeObj = mUiAutomationBridge.get(UiDevice.getInstance());
               Method injectInputEvent = Class.forName("com.android.uiautomator.core.UiAutomatorBridge").getDeclaredMethod("injectInputEvent",new Class[]{android.view.InputEvent.class,boolean.class}); 
      
               final long eventTime = SystemClock.uptimeMillis(); 
               KeyEvent downEvent = new KeyEvent(eventTime, eventTime, KeyEvent.ACTION_DOWN,  keyCode, 0, 0, KeyCharacterMap.VIRTUAL_KEYBOARD, 0, 0, InputDevice.SOURCE_KEYBOARD);
               if ((Boolean) injectInputEvent.invoke(bridgeObj, new Object[]{downEvent, true})) { 
                    SystemClock.sleep(PressTime*1000);
                    KeyEvent upEvent = new KeyEvent(eventTime, eventTime, KeyEvent.ACTION_UP, keyCode, 0, 0, KeyCharacterMap.VIRTUAL_KEYBOARD, 0, 0, InputDevice.SOURCE_KEYBOARD);
                    if ((Boolean) injectInputEvent.invoke(bridgeObj, new Object[]{upEvent, true})) { 
                         return true; 
                    }
               }
          } catch (NoSuchMethodException e) { 
               e.printStackTrace(); 
          } catch (InvocationTargetException e) { 
               e.printStackTrace(); 
          } catch (NoSuchFieldException e) { 
               e.printStackTrace(); 
          } catch (IllegalAccessException e) { 
               e.printStackTrace(); 
          } catch (ClassNotFoundException e) { 
               e.printStackTrace(); 
          } 
          return false; 
     } 

2. 

//长按菜单键

boolean longpressRes = MdmHelper.longPressKeyCode(82, 4);
