推荐答案

这是一个Mediastore文件意味着录音。就像按一下按钮，开始记录

This is a Mediastore file means Audio Recording .just like click the button and start the recording

public class MediastoreActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
 Button btn = (Button)findViewById(R.id.recordBtn);
btn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View view) {
startRecording();
}});
}
public void startRecording() {
Intent intt = new Intent("android.provider.MediaStore.RECORD_SOUND");
startActivityForResult(intt, 0);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case 0:
if (resultCode == RESULT_OK) {
 Uri recordedAudioPath = data.getData();
}
}
}
}
