需求

當我們開啟一個服務運行的時候(查詢來電歸屬地)，但是可能會被用戶自行停止服務邮屁，或者被用戶的安(liu)全(mang)軟件殺掉整袁。那么我們需要查看自已的服務有沒有殺掉。

1. Setting_Activity：一個CheckBox勾選后開啟Service佑吝，設置CheckBox狀態(tài)為勾選
2. Service被殺掉坐昙，此時CheckBox狀態(tài)仍為勾選
3. 進入Setting_Activity界面時，CheckBox被勾選芋忿，但Service并未運行

邏輯

• 進入Setting_Activity炸客，檢查自已的Service的運行狀態(tài)盗飒，是否正在運行
  • 正在運行嚷量，設置CheckBox為勾選狀態(tài)
  • 未運行，設置CheckBox為未勾選狀態(tài)

判斷Service運行邏輯

public class ServiceRunning {
    /*
  判斷service是否運行
 */  public static boolean isRun(Context context,String serviceName){
        ActivityManager mActivityManager = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);
  List<ActivityManager.RunningServiceInfo> runServiceList = mActivityManager
                .getRunningServices(100);
 for (ActivityManager.RunningServiceInfo info:runServiceList){
            System.out.println(info.service.getClassName());
  String name=info.service.getClassName();

 if (serviceName.equals(name)){
                return true;
  }
        }
        return false;
  }
}

Service邏輯

public class comPhone extends Service {
    private TelephonyManager telephonyManager;
 private Mylisten mylisten;
  @Nullable
 @Override  public IBinder onBind(Intent intent) {
        return null;
  }

    @Override
  public void onCreate() {
        super.onCreate();
  telephonyManager= (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
  mylisten=new Mylisten();
  telephonyManager.listen(mylisten,PhoneStateListener.LISTEN_CALL_STATE);
  }
    class Mylisten extends PhoneStateListener{
        @Override
  public void onCallStateChanged(int state, String incomingNumber) {
            super.onCallStateChanged(state, incomingNumber);
 switch(state){
                //電話等待接聽
  case TelephonyManager.CALL_STATE_RINGING:
                    System.out.println(AddressDao.getAdress(incomingNumber));
 break;  //電話接聽
  case TelephonyManager.CALL_STATE_OFFHOOK:
                    break;
  //電話掛機
  case TelephonyManager.CALL_STATE_IDLE:

                    break;
  }
        }
    }

    @Override
  public void onDestroy() {
        super.onDestroy();
  telephonyManager.listen(mylisten,TelephonyManager.PHONE_TYPE_NONE);
  }
}

Setting_Activity的Checkbox啟動(關閉)服務

boolean running=ServiceRunning.isRun(this,"com.phonesafe.service.comPhone");
if (running){
    set_item1.setCheck(true);
}else {
    set_item1.setCheck(false);
}
isUpdate.setOnClickListener(new View.OnClickListener() {
    @Override
  public void onClick(View v) {
        if (isUpdate.isChecked()){
            set_item1.setCheck(true);
  Intent start=new Intent(Setting.this,comPhone.class);
  startService(start);
  }else{
            set_item1.setCheck(false);
  stopService(new Intent(Setting.this,comPhone.class));
  }
    }
});
