帶有API 16和Webview的MotionEvent（Android）

Question

我想製作一個MotionEvent來控制一個webiew。如果API低於16一切正常用：

long downTime = SystemClock.uptimeMillis(); 
    long eventTime = SystemClock.uptimeMillis() + 500; 
    float x = 50f; 
    float y = 50f; 
    // List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState() 
    int metaState = 0; 
    MotionEvent me = MotionEvent.obtain(
     downTime, 
     eventTime, 
     action, 
     x, 
     y, 
     metaState 
    ); 

    view.dispatchTouchEvent(me); 

不過是API更高，然後我得到一個錯誤有：不是來自SOURCE_CLASS_PIONTER。然後我將代碼更改爲：

long downTime = SystemClock.uptimeMillis(); 
    long eventTime = SystemClock.uptimeMillis() + 500; 
    float x = 50f; 
    float y = 50f; 
    // List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState() 
    int metaState = 0; 
    MotionEvent.PointerCoords p[] = null; 
    MotionEvent.PointerProperties p2[] = null; 
    p[0] = new MotionEvent.PointerCoords(); 
p[0].x = x; 
p[0].y = y; 
p2[0] = new MotionEvent.PointerProperties(); 
p2[0].toolType = MotionEvent.TOOL_TYPE_FINGER; 
p2[0].id = 0; 
MotionEvent me = MotionEvent.obtain(downTime, eventTime, action, 1, p2, p, metaState, 0, 1f, 1f, 0,0, 0, 0); 
    view.dispatchTouchEvent(me); 

但它沒有工作。你有沒有可以幫助我？ 對不起，我的英語不好。

來自德國的問候。

Answer 1

MotionEvent me = MotionEvent.obtain(
     downTime, 
     eventTime, 
     action, 
     x, 
     y, 
     metaState 
    ); 
    me.setSource(4098); 
    view.dispatchTouchEvent(me); 

適合我。
