Android Send event 汇总 （点击，滑动，两指操作 源码）

UiAutomation 跨应用操作三大利器：

setOnAccessibilityEventListener() 开启Accessibility

executeShellCommand() 执行shell命令（权限比Runtime.getRuntime().exec()高，相当于adb shell）

injectInputEvent() 注入事件，比如点击。

EventCode

public static final int ACTION_DOWN             = 0;
public static final int ACTION_UP               = 1;
public static final int ACTION_MOVE             = 2;

先看看send event的方法：

Send Event

1.Instrumentation

Instrumentation inst = new Instrumentation();
nst.sendPointerSync

2.Uiautomation

mUiAutomation.injectInputEvent

3.IWindowManager

IWindowManager.Stub.asInterface(ServiceManager.getService("window"));

4.InputManager

MotionEvent me = getEvent();
InputManager.getInstance().injectInputEvent(me, 1)

 5.IWindowManager 

IBinder wmbinder = ServiceManager.getService( "window" ); 
IWindowManager m_WndManager = IWindowManager.Stub.asInterface( wmbinder ); 
// key down 
m_WndManager.injectKeyEvent( new KeyEvent( KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_A ),true ); 
// key up

m_WndManager.injectKeyEvent( new KeyEvent( KeyEvent.ACTION_UP, KeyEvent.KEYCODE_A ),true );

6./dev/input/eventX  这个需要权限哦

Touch

MotionEvent event = MotionEvent.obtain(downTime, eventTime, 0, (float) x, (float) y, 0);  //dowm
inst.sendPointerSync(MotionEvent.obtain(300 + downTime, 300 + eventTime, 1, (float) x, (float) y, 0));  //up

Swipe

   xStep = (double)(upX - downX) / (double)swipeSteps;
        yStep = (double)(upY - downY) / (double)swipeSteps;
        ret = this.touchDown(downX, downY);
        if(drag) {
            SystemClock.sleep(this.mUiAutomatorBridge.getSystemLongPressTime());
        }

        for(int i = 1; i < swipeSteps; ++i) {
            ret &= this.touchMove(downX + (int)(xStep * (double)i), downY + (int)(yStep * (double)i));
            if(!ret) {
                break;
            }

            SystemClock.sleep(5L);
        }

        if(drag) {
            SystemClock.sleep(100L);
        }

        ret &= this.touchUp(upX, upY);

pinchOpen

  private static MotionEvent getMotionEvent(long downTime, long eventTime, int action, List<PointerProperties> properties, List<PointerCoords> coordinates) {
        PointerProperties[] props = (PointerProperties[])properties.toArray(new PointerProperties[properties.size()]);
        PointerCoords[] coords = (PointerCoords[])coordinates.toArray(new PointerCoords[coordinates.size()]);
        return MotionEvent.obtain(downTime, eventTime, action, props.length, props, coords, 0, 0, 1.0F, 1.0F, 0, 0, 4098, 0);
    }
