我的代码:语音录制节目
public class MainActivity extends AppCompatActivity {
private Button mRecordBtn;
private TextView mRecordLabel;
private MediaRecorder mRecorder;
private String mFileName = null;
private static final String LOG_TAG = "Record_log";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRecordLabel = (TextView) findViewById(R.id.recordLabel);
mRecordBtn = (Button) findViewById(R.id.recordBtn);
mFileName = Environment.getExternalStorageDirectory().getAbsolutePath();
mFileName = "/recorded_audio.3gp";
mRecordBtn.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent motionEvent) {
if(motionEvent.getAction() == MotionEvent.ACTION_DOWN){
startRecording();
mRecordLabel.setText("Recording in Progress");
}
else if (motionEvent.getAction() == MotionEvent.ACTION_UP){
stopRecording();
mRecordLabel.setText("Recording Stopped");
}
return false;
}
});
}
private void startRecording() {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setOutputFile(mFileName);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
try {
mRecorder.prepare();
} catch (IOException e) {
Log.e(LOG_TAG, "prepare() failed");
}
mRecorder.start(); //I am getting a bug on this line
}
private void stopRecording() {
mRecorder.stop();
mRecorder.release();
mRecorder = null;
}
}
