android - 单击editText时如何选择音频文件？

Question

单击片段类(ReminderPage)中的editText时，我希望它打开音频文件，以便可以选择音乐文件作为铃声。

ringtone.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View arg0) {

                        Intent intent1 = new Intent();
                        intent1.setAction(Intent.ACTION_GET_CONTENT);
                        intent1.setType("audio/*");
                        startActivityForResult(
                                Intent.createChooser(intent1, "Choose Sound File"), 6);
                    }
                });

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data,Context context) {
        if (resultCode == getActivity().RESULT_OK && requestCode == 6) {
            Uri i = data.getData();  // getData
            String s = i.getPath(); // getPath
            File k = new File(s);  // set File from path
            if (s != null) {      // file.exists

                ContentValues values = new ContentValues();
                values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
                values.put(MediaStore.MediaColumns.TITLE, "ring");
                values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
                values.put(MediaStore.MediaColumns.SIZE, k.length());
                values.put(MediaStore.Audio.Media.ARTIST, R.string.app_name);
                values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
                values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
                values.put(MediaStore.Audio.Media.IS_ALARM, true);
                values.put(MediaStore.Audio.Media.IS_MUSIC, false);

                Uri uri = MediaStore.Audio.Media.getContentUriForPath(k
                        .getAbsolutePath());
                context.getContentResolver().delete(
                        uri,
                        MediaStore.MediaColumns.DATA + "=\""
                                + k.getAbsolutePath() + "\"", null);
                Toast.makeText(getActivity(),values+"",Toast.LENGTH_LONG).show();
                Uri newUri = context.getContentResolver().insert(uri, values);

                try {
                    RingtoneManager.setActualDefaultRingtoneUri(
                            getActivity().ReminderPage, RingtoneManager.TYPE_RINGTONE,
                            newUri);
                } catch (Throwable t) {

                }
            }
        }
    }

但是我遇到了错误，并且从未使用过onActivityResult。

Error:(473, 42) error: cannot find symbol variable ReminderPage Error:(443, 5) error: method does not override or implement a method from a supertype

在我更改为getActivity()。getContentResolver()和Reminder.this之后，我得到了新的错误

Error:(444, 20) error: onActivityResult(int,int,Intent) in ReminderPage cannot override onActivityResult(int,int,Intent) in Fragment attempting to assign weaker access privileges; was public Error:(472, 36) error: method setActualDefaultRingtoneUri in class RingtoneManager cannot be applied to given types; required: Context,int,Uri found: ReminderPage,int,Uri reason: actual argument ReminderPage cannot be converted to Context by method invocation conversion

Answer 1

对于第一个错误，请在调用getActivity().ReminderPage时尝试用getActivity()替换setActualDefaultRingtoneUri。

关于第二个错误:Fragment.onActivityResult方法中没有Context context参数，可见性应为public。覆盖方法时，必须尊重方法的签名。

更换

protected void onActivityResult(int requestCode, int resultCode, Intent data,Context context) {

通过

public void onActivityResult(int requestCode, int resultCode, Intent data) {

并更换

context.getContentResolver()

通过

getActivity().getContentResolver()
