问题描述
我从AudioRecorder试图记录，那么我想打相同的媒体播放器，但其给媒体播放器。prepare（）未能prepare。难道任何一个告诉我什么可能合适的理由。下面是code我使用
I am trying record from the AudioRecorder then I am trying to play the same with Media Player, But its giving mediaplayer.prepare() failed to prepare. Could any one tell me what could appropriate reason.Below is the code I am using
public void onClick(View v) {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
if(case_value==0)
recorder.setOutputFile(deviceMIC_path);
else if(case_value==1)
recorder.setOutputFile(deviceMIC_Handset_path);
else if(case_value==2)
recorder.setOutputFile(headsetMIC_path);
recorder.setOnErrorListener(errorListener);
recorder.setOnInfoListener(infoListener);
try {
recorder.prepare();
recorder.start();
if (ENABLE_LOGS)
Log.e(LOG_TAG, resources
.getString(R.string.record_started));
Toast.makeText(context,
resources.getString(R.string.record_started),
Toast.LENGTH_LONG).show();
recording = true;
} catch (IllegalStateException e) {
Log.e("","ILLEAGAL EXCEPTION...");e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
Log.e("","IO EXCEPTION...");
}
catch(Exception e){
e.printStackTrace();
Log.e("","UNKNOWN EXCEPTION...");
}
}
});
stopButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (recording) {
if (ENABLE_LOGS)
Log.e(LOG_TAG, "Record is going to be stoped...");
recorder.stop();
if (ENABLE_LOGS)
Log.e(LOG_TAG, "Record STOPPED....");
Toast
.makeText(context, "Record STOPPED",
Toast.LENGTH_LONG).show();
recorder.release();
recorder=null;
}
}
});
playButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MediaPlayer mediaplayer = new MediaPlayer();
try {
if(case_value==0)
mediaplayer.setDataSource(deviceMIC_path);
else if(case_value==1)
mediaplayer.setDataSource(deviceMIC_Handset_path);
else if(case_value==2)
mediaplayer.setDataSource(headsetMIC_path);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
mediaplayer.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
catch(Exception e){
e.printStackTrace();
}
// mAudioManager.setSpeakerphoneOn(false);
if (ENABLE_LOGS)
Log.e(LOG_TAG, "CASE VALUE : " + case_value);
if (case_value == 0) {
if (MainActivity.headsetState == 0) {
if (!mediaplayer.isPlaying()) {
mediaplayer.start();
if (ENABLE_LOGS)
Log.e(LOG_TAG, "PLAY started...");
Toast.makeText(context, "PLAY started...",
Toast.LENGTH_LONG).show();
} else {
mediaplayer.stop();
}
下面是错误我收到

难道任何一个，请告诉我解决这个问题的办法。
Could any one please tell me the way to resolve this problem.
推荐答案
实施OnCompletionListener，并与您的MediaPlayer实例进行注册。
Implement the OnCompletionListener and register it with your MediaPlayer instance.
在媒体已经发挥出它会调用这个回调方法onCompletion
After the media has been played out it will call this callback method onCompletion
void onCompletion(MediaPlayer mp){
//Here you stop it.
mp.stop();
//Reset the data source path to the new file
mp.setDataSource(<uri>);
mp.prepare(); // or mp.prepareAsync();
// start the mediaplayer after the prepare has completed.
}
松开媒体播放器实例，一旦你完成播放的所有文件。
Release the mediaplayer instance once you are done playing all the files.
