Explorer在我的应用程序中使用

Question

当我点击按钮时，程序询问我想要使用哪个文件管理器（或Dropbox等）。然后我选择，例如，.mp3文件。我怎么能告诉我的程序启动这个.mp3，什么时候我需要它？如何记住这个选择的文件？

<ul>
  <li>
    <ol>
      <li>Start with the function keyword</li>
      <li>Inputs go between ()</li>
      <li>Actions go between {}</li>
      <li>jQuery is for chumps!</li>
    </ol>
     <ol>
      <li>Start with the function keyword</li>
      <li>Inputs go between ()</li>
      <li>Actions go between {}</li>
      <li>jQuery is for chumps!</li>
    </ol>
     <ol>
      <li>Start with the function keyword</li>
      <li>Inputs go between ()</li>
      <li>Actions go between {}</li>
      <li>jQuery is for chumps!</li>
    </ol>
     <ol>
      <li>Start with the function keyword</li>
      <li>Inputs go between ()</li>
      <li>Actions go between {}</li>
      <li>jQuery is for chumps!</li>
    </ol>
  </li>
  <li>Inputs are separated by commas.</li>
  <li>Inputs can include other functions!</li>
</ul>

试试这个

Uri myUri = Uri.parse(entry.getFile());
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(myUri, "audio/*");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
