Question

其实我是Android开发人员的新手，我在我的活动类中有一个停止按钮，我想停止电话服务，以便在点击停止按钮后它不会记录呼叫，但它不是停止服务而是记录电话。请帮助解决问题

我的活动课程是

package com.jain.callrecorderdemo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
Button startbtn, stopbtn;
@Override
protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.main);
    super.onCreate(savedInstanceState);
    startbtn = (Button) findViewById(R.id.startbtnid);
    stopbtn = (Button) findViewById(R.id.stopbtnid);
    startbtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent in = new Intent(getApplicationContext(), CallRecordingService.class);
            startService(in);

        }
    });
    stopbtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent in = new Intent(getApplicationContext(), CallRecordingService.class);
            stopService(in);

        }
    });
}
}

我的CallREcorder服务

package com.jain.callrecorderdemo;
import java.io.File;
import java.io.IOException;
import android.app.Service;
import android.content.Intent;
import android.media.MediaRecorder;
import android.os.Environment;
import android.os.IBinder;
import android.preference.PreferenceManager.OnActivityStopListener;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.widget.Toast;

public class CallRecordingService extends Service{

TelephonyManager tm;
MediaRecorder mr;
static int x=0;
int id;
@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
} 

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    id=startId;
    tm=(TelephonyManager) getSystemService(TELEPHONY_SERVICE);
    tm.listen(new MyPhoneListener(), PhoneStateListener.LISTEN_CALL_STATE);
    return super.onStartCommand(intent, flags, startId);
}
@Override
public void onDestroy() {

Toast.makeText(getApplicationContext(), "Call Recorder off", Toast.LENGTH_LONG).show();

    super.onDestroy();
}


class MyPhoneListener extends PhoneStateListener
{
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        super.onCallStateChanged(state, incomingNumber);
        switch (state) {
        case TelephonyManager.CALL_STATE_IDLE:
            Toast.makeText(getApplicationContext(), "IDLE", Toast.LENGTH_LONG).show();
            try {
                mr.release();   
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
            }

            break;

        case TelephonyManager.CALL_STATE_RINGING:
            Toast.makeText(getApplicationContext(), "Ringing", Toast.LENGTH_LONG).show();
            break;

        case TelephonyManager.CALL_STATE_OFFHOOK:
            Toast.makeText(getApplicationContext(), "OFFHOOK", Toast.LENGTH_LONG).show();
            try {
                mr=new MediaRecorder();
                mr.setAudioSource(MediaRecorder.AudioSource.MIC);
                mr.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
                mr.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
                File mysdpath=Environment.getExternalStorageDirectory();
                File mydir=new File(mysdpath,"Recording_folder");
                if(mydir.exists()==false)
                {
                    mydir.mkdir();
                }
                String filepath=mydir.getAbsolutePath()+"/recorderfile"+(x++)+".mp3";
                mr.setOutputFile(filepath);
                mr.prepare();
                mr.start();
                Toast.makeText(getApplicationContext(), "Recording started", Toast.LENGTH_LONG).show();
            } catch (IllegalStateException e) {
                Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
                e.printStackTrace();
            } catch (IOException e) {
                Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
                e.printStackTrace();
            }

            break;
        }
    }
}
}

我的清单文件是

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.jain.callrecorderdemo"
android:versionCode="1"
android:versionName="1.0" >

Answer 1

您可以使用LISTEN_NONE作为参数来停止侦听更新。

telephonymanager.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE );

希望这会对你有所帮助，谢谢。
