Android在来电时关闭媒体服务

概述我真的是android和java的新手.我正在制作一个应用程序,它具有媒体服务,我希望在来电时停止或暂停媒体.这是我的媒体服务代码公共类ServiceMusic扩展Service{MediaPlayermusic;@OverridepublicIBinderonBind(Intentarg0){returnnull;}@Overridepublicvoido

我真的是android和java的新手.我正在制作一个应用程序,它具有媒体服务,我希望在来电时停止或暂停媒体.
这是我的媒体服务代码

公共类ServiceMusic扩展Service {

MediaPlayer music;@OverrIDepublic IBinder onBind(Intent arg0) {    return null;}@OverrIDepublic voID onDestroy() {    super.onDestroy();    music.stop();    music.release();}@OverrIDepublic voID onStart(Intent intent, int startID) {    super.onStart(intent, startID);    if (music !=null)    music.stop();    music = MediaPlayer.create(ServiceMusic.this, R.raw.music);    music.start();    music.setLooPing(true);}

}

如果您能为我提供帮助,并且能给我完整的指导,那将是非常不错的.
谢谢

解决方法:

您必须为来话呼叫创建接收方,如下所示：

public class call_reciver extends broadcastReceiver {    @OverrIDe    public voID onReceive(Context context, Intent intent) {        // Todo auto-generated method stub        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);        String number = "";        Bundle bundle = intent.getExtras();        if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {            // Phone is ringing            number = bundle.getString("incoming_number");        } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {            // Call received        } else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {            // Call Dropped or rejected        }    }

在清单中放入：

<receiver androID:name=".call_reciver" >            <intent-filter>                <action androID:name="androID.intent.action.PHONE_STATE" />            </intent-filter>        </receiver>

许可：

<uses-permission androID:name="androID.permission.READ_PHONE_STATE" >    </uses-permission>

使您的媒体播放器变量变为静态&全局,在接收方呼叫另一个服务以检查您的媒体播放器是否正在运行.如果它正在运行,则停止它.您可以使用也可以使用相同的服务.

您必须从接收方启动服务：

Intent myIntent = new Intent(context, Service_temp.class);        context.startService(myIntent);

在使用中使用此：

@OverrIDe    public int onStartCommand(Intent intent, int flags, int startID) {        // Todo auto-generated method stub        return super.onStartCommand(intent, flags, startID);    }

检查编辑的ans：

在下面的示例中,我已完成所有 *** 作.有一个按钮可以播放正在播放的歌曲.那时您收到来电,它将停止您的服务(停止播放歌曲),当您拒绝或挂断电话时,它将再次开始播放歌曲

主要活动类别：

package com.example.androIDmediaplay;import androID.os.Bundle;import androID.app.Activity;import androID.content.Intent;import androID.vIEw.Menu;import androID.vIEw.VIEw;public class MainActivity extends Activity {    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_main);    }    @OverrIDe    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.activity_main, menu);        return true;    }    public voID clickBtn(VIEw v) {        if (v.getID() == R.ID.button1) {            UtilClass.playing = true;            Intent i = new Intent(MainActivity.this,                    BackgroundSoundService.class);            startService(i);        }    }}

BackgroundSoundService类：

package com.example.androIDmediaplay;import java.io.file;import androID.app.Service;import androID.content.Intent;import androID.media.MediaPlayer;import androID.net.Uri;import androID.os.Environment;import androID.os.IBinder;import androID.util.Log;public class BackgroundSoundService extends Service {    private static final String TAG = null;    MediaPlayer player;    public IBinder onBind(Intent arg0) {        return null;    }    @OverrIDe    public voID onCreate() {        super.onCreate();        player = MediaPlayer.create(                this,                Uri.fromfile(new file(Environment.getExternalStorageDirectory()                        + "/Songs/test.mp3")));        player.setLooPing(true); // Set looPing        player.setVolume(100, 100);    }    public int onStartCommand(Intent intent, int flags, int startID) {        Log.e("onStartCommand", "onStartCommand");        if (player.isPlaying()) {            player.pause();            UtilClass.pause = true;            Log.e("onStartCommand pause", "onStartCommand pause");        } else {            UtilClass.pause = false;            player.start();        }        return 1;    }    public voID onStart(Intent intent, int startID) {        // TO DO    }    public IBinder onUnBind(Intent arg0) {        // TO DO auto-generated method        return null;    }    public voID onStop() {    }    public voID onPause() {    }    @OverrIDe    public voID onDestroy() {        UtilClass.playing = false;        player.stop();        player.release();    }    @OverrIDe    public voID onLowMemory() {    }}

呼叫接收者类别：

package com.example.androIDmediaplay;import androID.app.ActivityManager;import androID.app.ActivityManager.RunningServiceInfo;import androID.content.broadcastReceiver;import androID.content.Context;import androID.content.Intent;import androID.content.SharedPreferences;import androID.content.SharedPreferences.Editor;import androID.os.Bundle;import androID.preference.PreferenceManager;import androID.telephony.TelephonyManager;import androID.util.Log;public class call_reciver extends broadcastReceiver {    @OverrIDe    public voID onReceive(Context context, Intent intent) {        // Todo auto-generated method stub        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);        String number = "";        Bundle bundle = intent.getExtras();        if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {            // Phone is ringing            number = bundle.getString("incoming_number");            Log.e("incoming_number", "incoming_number");            _stopServices(context);        } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {            // Call received        } else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {            // Call Dropped or rejected            _stopServices(context);        }    }    private voID _stopServices(Context con) {        // Todo auto-generated method stub        if (UtilClass.playing == true) {            Log.e("start services", "start services");            Intent i = new Intent(con, BackgroundSoundService.class);            con.startService(i);        } else {            Log.e("start not services", "start not services");        }    }}

静态成员的额外类：

package com.example.androIDmediaplay;public class UtilClass {    public static Boolean playing = false;    public static boolean pause = false;}

在最后一个清单文件中：

<?xml version="1.0" enCoding="utf-8"?><manifest xmlns:androID="http://schemas.androID.com/apk/res/androID"    package="com.example.androIDmediaplay"    androID:versionCode="1"    androID:versionname="1.0" >    <uses-sdk        androID:minSdkVersion="8"        androID:targetSdkVersion="17" />    <uses-permission androID:name="androID.permission.READ_PHONE_STATE"/>    <application        androID:allowBackup="true"        androID:icon="@drawable/ic_launcher"        androID:label="@string/app_name"        androID:theme="@style/Apptheme" >        <activity            androID:name="com.example.androIDmediaplay.MainActivity"            androID:label="@string/app_name" >            <intent-filter>                <action androID:name="androID.intent.action.MAIN" />                <category androID:name="androID.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <service            androID:name=".BackgroundSoundService"            androID:enabled="true" >        </service>        <receiver androID:name=".call_reciver" >            <intent-filter>                <action androID:name="androID.intent.action.PHONE_STATE" />            </intent-filter>        </receiver>    </application></manifest>

所有代码都在我的工作端.请检查并告诉我.
