Question

这里我想调用android.view.View :: dispatchPointerEvent方法。当我这样做时，我得到以下异常：

java.lang.IllegalArgumentException: expected receiver of type android.view.View, but got java.lang.Class<android.view.View>

        at com.android.internal.os.ZygoteInit.main(Native Method)
        at dalvik.system.NativeStart.main(Native Method)

这是代码

static void injectMyCrap() {
    Log.i("JSLock-injectMyCrap","I got called");
    Class _class = null;

    try {
        _class = Class.forName("android.view.View");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    Method method = null;
    try {

        method = _class.getMethod("dispatchPointerEvent", MotionEvent.class);
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    }
    try {
        MotionEvent evntDown = MotionEvent.obtain( SystemClock.uptimeMillis(),
                SystemClock.uptimeMillis(),
                MotionEvent.ACTION_DOWN,
                10, 10, 0);
        method.invoke(_class,evntDown);

        MotionEvent evntUp = MotionEvent.obtain( SystemClock.uptimeMillis(),
                SystemClock.uptimeMillis(),
                MotionEvent.ACTION_UP,
                10, 10, 0);
        method.invoke(_class,evntUp);

    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    }

}

或者我可能需要创建STUB？我不知道怎么样，有什么帮助吗？

您必须将其强制转换为View对象:(查看）method.invoke（_class，eventUp）;

Android反射 - 调用方法
