问题描述
我需要模拟 DragEvent 进行测试。但是，我无法访问 DragEvent.obtain（）方法。
I need to simulate DragEvent for testing purpose. However I am not able to access DragEvent.obtain() method.
请建议一种方式模拟DragEvent ，以便我可以为DragListener的onDrag（）方法定义DragEvent的操作
Please suggest a way to simulate DragEvent such that I can define actions for DragEvent in onDrag() method of DragListener
对于Touch MotionEvent，我们可以这样做通过MotionEvent.obtain（）和传递相关参数，但是如果DragEvent
For Touch MotionEvent, we could do so by MotionEvent.obtain() and passing relevant parameters, however this method is not accessible in case of DragEvent
推荐答案
DragEvent .obtain（）是一个内部的API函数，它不被 @hide 注释所显示。
DragEvent.obtain() is an internal API function which is not exposed yet as seen by @hide annotation.
作为解决方法，您可以从包裹对象
As a wayaround, you can create a DragEvent from parcelable objecthttp://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.3_r1/android/view/DragEvent.java#488
DragEvent.CREATOR.createFromParcel(parcel);
Parcel parcel = Parcel.obtain();
parcel.writeInt(action);
parcel.writeFloat(x);
parcel.writeFloat(y);
parcel.writeInt(0); // Result
parcel.writeInt(0); // No Clipdata
parcel.writeInt(0); // No Clip Description
parcel.setDataPosition(0);
如果要添加Clipdata，请参阅createFromParcel（）方法。
If you want to add Clipdata, see it's createFromParcel() method.
