java - android 调用系统录音机并能返回含所录音频的

Answer 1

Audio is also obtained in onActivityResult
Call system audio:

        Intent intent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
        startActivityForResult(intent, RECORD_AUDIO);

Get Uri:

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
            case RECORD_AUDIO:
                try {
                    Uri uri = data.getData();
                    String filePath = getAudioFilePathFromUri(uri);
                    Log.d(TAG, filePath);
                } catch (Exception e) {
                    throw new RuntimeException(e);
                }
                break;
        }
    }

    private String getAudioFilePathFromUri(Uri uri) {
        Cursor cursor = getContentResolver()
                .query(uri, null, null, null, null);
        cursor.moveToFirst();
        int index = cursor.getColumnIndex(MediaStore.Audio.AudioColumns.DATA);
        return cursor.getString(index);
    }

filePath is the audio file you recorded, you can copy it to any location.
Don’t forget to add uses-permission related permissions
