我的活动中有两种方法，一种是setOnClickListener()，另一种是setOnLongClickListener()
对于用于开始录音的相同按钮。
现在我不知道如何使用条件，如果我使用setOnClickListener()那么录音应该开始1分钟并自动停止，如果我使用setOnLongClickListener()然后录制开始2分钟然后自动停止。
buttonStart.setOnLongClickListener(new OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
Toast.makeText(Record_Audio.this,
"Start Recording With LongClick", Toast.LENGTH_SHORT)
.show();
enableButtons(true);
startRecording();
return true;
}
});
private View.OnClickListener btnClick = new View.OnClickListener() {
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnStart: {
Toast.makeText(Record_Audio.this, "Start Recording",
Toast.LENGTH_SHORT).show();
enableButtons(true);
startRecording();
break;
}
}
});
private void startRecording() {
displayAlertDialog();
}
private void displayAlertDialog() {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(
Record_Audio.this);
alertDialog.setTitle("Would you Like to save your Recording");
alertDialog.setMessage("Enter Audio Name");
alertDialog.setIcon(R.drawable.save_icon);
final EditText editTextAudioName = new EditText(Record_Audio.this);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
editTextAudioName.setLayoutParams(lp);
alertDialog.setView(editTextAudioName);
alertDialog.setPositiveButton("Save",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Code.audioName = editTextAudioName.getText().toString()
.trim();
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(output_formats[currentFormat]);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(getFilename());
recorder.setOnErrorListener(errorListener);
recorder.setOnInfoListener(infoListener);
try {
recorder.prepare();
recorder.start();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
myChronometer.setBase(SystemClock.elapsedRealtime());
myChronometer.start();
}
});
alertDialog.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Write your code here to execute after dialog
dialog.cancel();
}
});
alertDialog.show();
}
我知道我必须在特定时间间隔内使用setMaxDuration，但我不知道如何使用这两种方法。
提前致谢。
答案 0 :(得分：0)
无论如何，MediaRecorder Api不是使用录音音频的好方法。使用AudioRecorder API。
让我解释一下

开始和停止记录
<强> MainActivity
TaukkyRecordr taukyrecorder=new Taukyrecorder(mcontext);
taukyrecorder.startRecording();
//For stop
taukyrecorder.stopRecording();
如果您想在几秒钟后自动停止，请创建一个主题。
public class StopRecord extends Thread {
int i = 0;
@Override
public void run() {
// TODO Auto-generated method stub
super.run();
handler.post(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
taukyrecorder.stopRecording();
}
});
}
}
然后使用处理程序
调用线程Handker mhandler=new Handeler;
mhandler.postDelayed(mRunnable, 1000);//put your secodn here
