这里我想记录来自15555215556的电话，因为我给了IF条件 - “String aa =”15555215556“; if（aa.equals（incomingNumber））”。如果incomingNumber等于aa，它应该开始录制，但不能录制。
公共类记录扩展了BroadcastReceiver {
PhoneStateListener listener;
TelephonyManager telephony;
MediaRecorder recorder = new MediaRecorder();
boolean recordStarted;
String phonenumber;
@Override
public void onReceive(final Context context, final Intent intent) {
// TODO Auto-generated method stub
telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
listener = new PhoneStateListener() {
public void onCallStateChanged(int state, String incomingNumber) {
//want to record call from 15555215556
String aa="15555215556";
if(aa.equals(incomingNumber)){
phonenumber=incomingNumber;
System.out.println(""+phonenumber);
try{
switch(state)
{
case TelephonyManager.CALL_STATE_IDLE:
{
Log.d("DEBUG", "IDLE");
StopRecording();
break;
}
case TelephonyManager.CALL_STATE_RINGING:
{
Log.d("DEBUG", "RINGING");
StopRecording();
break;
}
case TelephonyManager.CALL_STATE_OFFHOOK:
{
Log.d("DEBUG", "OFFHOOK");
StartRecording();
break;
}
}
}
catch (Exception e) {
// TODO: handle exception
}
}
}
public void StartRecording(){
try{
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(this.getFullSdPath());
recorder.prepare();
recorder.start(); // Recording is now started
Log.i(this.getClass().getName(), "Start Recording");
}
catch (Exception e) {
// TODO: handle exception
}
}
public void StopRecording(){
recorder.stop();
recorder.release();
recorder = null;
Log.i(this.getClass().getName(), "Stop Recording");
}
public String getFullSdPath(){
File sdCard = new File(Environment.getExternalStorageDirectory() + "/RecordMyVoice");
if (!sdCard.exists()) {
sdCard.mkdir();
}
File file = new File(Environment.getExternalStorageDirectory() +"/RecordMyVoice/",new Date().getTime()+".mp3");
System.out.println("Full path of record sound is : "+file.getAbsolutePath());
return file.getAbsolutePath();
}
};
telephony.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
}

我的代码有什么问题吗？

在这里，您只能在“onCallStateChanged”中获取一次传入号码，因此您需要将该号码置于共享首选项中，最好在振铃状态下获取该号码
myprefs=context.getSharedPreferences("myprefs",001);
final SharedPreferences.Editor prefseditor=myprefs.edit();
try{
switch(state)
{
case TelephonyManager.CALL_STATE_IDLE:
{
try
{
Log.d("DEBUG", "IDLE");
StopRecording();
}
catch (Exception e) {
// TODO: handle exception
}
break;
}
case TelephonyManager.CALL_STATE_RINGING:
{
prefseditor.putString("in",incomingNumber);
prefseditor.commit();
Log.d("DEBUG", "RINGING");
StopRecording();
break;
}
case TelephonyManager.CALL_STATE_OFFHOOK:
{
no1=myprefs.getString("in", "nothing");
System.out.println("INCOMING"+no1);
Log.d("DEBUG", "OFFHOOK");
String aa="15555215556";
if(aa.equals(no1)){
StartRecording();
break;
}
}
}
}
catch (Exception e) {
// TODO: handle exception
}
super.onCallStateChanged(state, incomingNumber);
}
private void StartRecording() {
// TODO Auto-generated method stub
try{
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(this.getFullSdPath());
recorder.prepare();
recorder.start(); // Recording is now started
Log.i(this.getClass().getName(), "Start Recording");
}
catch (Exception e) {
