java - 如何从Intent接收文件路径

Question

在我的应用程序中，我有一个文本编辑器，其中包含我的应用程序要处理的文件的路径。我有一个浏览按钮，以便用户可以选择文件。选择文本后，编辑应包含路径/文件信息。在按钮的 onClick 方法中，我有以下代码:

 Intent intent = new Intent( Intent.ACTION_GET_CONTENT ); 
 intent.setType ( "*/*" );
 startActivity ( Intent.createChooser ( intent, "Select a file" ) );

用户完成后如何获取Uri？

startActivityForResult() 每 dev guide ，置顶推荐Android docs on Intents

Starting an activity

An Activity represents a single screen in an app. You can start a new instance of an > Activity by passing an Intent to startActivity(). The Intent describes the activity to start and carries any necessary data.

If you want to receive a result from the activity when it finishes, call startActivityForResult(). Your activity receives the result as a separate Intent object in your activity's onActivityResult() callback. For more information, see the Activities guide.
