Question

我正在尝试检测网页浏览中的滑动手势。

我尝试使用以下功能：

public boolean onTouchEvent(MotionEvent event) {

    int action = MotionEventCompat.getActionMasked(event);
    String DEBUG_TAG = "test";

    switch (action) {
        case (MotionEvent.ACTION_DOWN):
            Log.d(DEBUG_TAG, "Action was DOWN");
            return true;
        case (MotionEvent.ACTION_MOVE):
            Log.d(DEBUG_TAG, "Action was MOVE");
            return true;
        case (MotionEvent.ACTION_UP):
            Log.d(DEBUG_TAG, "Action was UP");
            return true;
        case (MotionEvent.ACTION_CANCEL):
            Log.d(DEBUG_TAG, "Action was CANCEL");
            return true;
        case (MotionEvent.ACTION_OUTSIDE):
            Log.d(DEBUG_TAG, "Movement occurred outside bounds " +
                    "of current screen element");
            return true;
        default:
            return super.onTouchEvent(event);
    }
}

当没有webview时，它会起作用并找回正确的答案。但是，当我添加上面的内容时，它在webview上不起作用。由于webview必须全屏，我想我不能使用上面的功能。有没有其他方法或我有什么问题？
