java - 如何在对话框子类内单击按钮时使用“创建选择器”

Question

使用此代码通过创建选择器共享音频文件但不起作用...

公共(public)类 ActionDialog 扩展 Dialog {

static String sSongTitle="";
static String sSongPath = "";
static File fSongFile ;

public ActionDialog(final Context context, Message response) {
    super(context);

    // Inflate our UI from its XML layout description.
    setContentView(R.layout.after_save_action);

    setTitle(R.string.alert_title_success);

    ((Button)findViewById(R.id.button_share))
    .setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                Uri StringUri = Uri.fromFile(new File(sSongPath)); 
                Intent intent = new Intent(android.content.Intent.ACTION_SEND, StringUri);
                Intent in = new Intent(android.content.Intent.ACTION_SEND, StringUri, context, null);
                intent.setType("audio/*");
                startActivity(Intent.createChooser(in, "select any from the list:"));//getting error here as create method startActivity(Intent)

            }
        });
}

}

你的 Intent 是 Intent 而不是ishare Uri 是 stringUri 但你提到 ed 为 StringUri.. 你可以发布完整的代码..以查看错误(如果有)
