android - 如何在单击按钮时将音频文件设置为铃声？

Question

我想将一个 mp3 文件设置为按下按钮时的铃声。我已将我的代码文件附在这个问题上。正如您在图像中看到的，我想在用户单击设置 1 按钮后将 shiv shiv 设置为铃声，对于其他设置按钮也是如此，每个设置按钮都会设置在其列中显示的铃声。

我添加了一些代码来将 mp3 设置为铃声，但它不起作用

创建方法并将其放入其中

 String filepath ="/sdcard/sample/"+currentName+"";
                            System.out.println("/sdcard/sample/"+currentName+"");


                            File ringtoneFile = new File(filepath);

                            ContentValues content = new ContentValues();
                            content.put(MediaStore.MediaColumns.DATA,ringtoneFile.getAbsolutePath());
                            content.put(MediaStore.MediaColumns.TITLE, currentName);
                            content.put(MediaStore.MediaColumns.SIZE, 215454);
                            content.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
                            //  content.put(MediaStore.Audio.Media.ARTIST, "Madonna");
                            content.put(MediaStore.Audio.Media.DURATION, 230);
                            content.put(MediaStore.Audio.Media.IS_RINGTONE, true);
                            content.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
                            content.put(MediaStore.Audio.Media.IS_ALARM, true);
                            content.put(MediaStore.Audio.Media.IS_MUSIC, true);

                        String Ringtonepath= "content://media/internal/audio/media/297";
                            Uri Ringtone1 = Uri.parse(filepath);   
                            //Insert it into the database
                            Log.i("TAG", "the absolute path of the file is :"+
                                    ringtoneFile.getAbsolutePath());
                            Uri uri = MediaStore.Audio.Media.getContentUriForPath(
                                    ringtoneFile.getAbsolutePath());




                            getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" + ringtoneFile.getAbsolutePath() + "\"",
                                      null);
                            Uri newUri = getContentResolver().insert(uri, content);
                            System.out.println("uri=="+uri);
                            Log.i("TAG","the ringtone uri is :"+newUri);
                               RingtoneManager.setActualDefaultRingtoneUri(
                                       getApplicationContext(), RingtoneManager.TYPE_RINGTONE,
                                       newUri);

然后在你的按钮点击中调用这个方法

如果你想让用户从他的设备中选择他自己的文件

添加下一行以获取文件路径

  Intent intent = new Intent();
      intent.setAction(Intent.ACTION_GET_CONTENT);
      intent.setType("file/*");
      startActivity(intent);
