Android监听系统来电并弹出提示窗口

1.问题

项目中有自己企业的通讯录，但是在应用中拨打公司通讯录的联系人，由于手机通讯录中没有相应的信息，只显示一串电话号

2 .目的

监听系统来电，获取到电话号码，通过调用接口，查询出来相应电话号码的详细信息，并弹出系统悬浮框，给用户提示。

3.实现

首先 注册广播监听系统来电。监听系统来电需要、注册相应的权限

代码地址：https://github.com/sdsjk/phone_alert.git

自定义广播去监听系统来电

 public class PhoneReceiver extends BroadcastReceiver {

  private Context mcontext;


  @Override
  public void onReceive(Context context, Intent intent){
    mcontext=context;
    System.out.println("action"+intent.getAction());
    if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
      //如果是去电（拨出）
      Log.e("TAG","拨出");
    }else{

      Log.e("TAG","来电");
      TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
      tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
      //设置一个监听器
    }
  }


  private PhoneStateListener listener=new PhoneStateListener(){

    @Override
    public void onCallStateChanged(int state, final String incomingNumber) {
      // TODO Auto-generated method stub
      //state 当前状态 incomingNumber,貌似没有去电的API
      super.onCallStateChanged(state, incomingNumber);
      switch(state){
 case TelephonyManager.CALL_STATE_IDLE:
   Log.e("TAG","挂断");

   break;
 case TelephonyManager.CALL_STATE_OFFHOOK:
   Log.e("TAG","接听");

   break;
 case TelephonyManager.CALL_STATE_RINGING:

   //输出来电号码
   Log.e("TAG","响铃:来电号码"+incomingNumber);
   Log.e("TAG","响铃:======"+Thread.currentThread().getName());

   break;
      }
    }
  };
  };

需要静态注册广播

其次在注册完，广播之后我们需要在监听到系统的来电之后，后获取到电话号之后去请求接口，获取数据。并弹出系统悬浮框。

注意：在弹出系统悬浮框的时候需要注册权限，并且检查应用的允许弹出悬浮框权限是否开启。

在监听中的 TelephonyManager.CALL_STATE_RINGING中操作

    inflate= LayoutInflater.from(mcontext);
wm = (WindowManager)mcontext.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams params = new WindowManager.LayoutParams();
params.type = WindowManager.LayoutParams.TYPE_PHONE;
params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
params.gravity= Gravity.CENTER;
params.width = WindowManager.LayoutParams.MATCH_PARENT;
params.height = 600;
params.format = PixelFormat.RGBA_8888;
phoneView=inflate.inflate(R.layout.phone_alert,null);
wm.addView(phoneView, params);

自定义一个布局文件，作为要添加的View，布局文件如下

使用到两个背景shape

      //如果是去电（拨出）
      Log.e("TAG","拨出");
    }else{
      //查了下android文档，貌似没有专门用于接收来电的action,所以，非去电即来电
      Log.e("TAG","来电");
      TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
      tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
      //设置一个监听器
    }
  }

  private TextView tv;

      super.onCallStateChanged(state, incomingNumber);
      switch(state){
 case TelephonyManager.CALL_STATE_IDLE:

   wm.removeView(tv);
   break;
 case TelephonyManager.CALL_STATE_OFFHOOK:
   Log.e("TAG","接听");
   wm.removeView(tv);
   break;
 case TelephonyManager.CALL_STATE_RINGING:

   inflate= LayoutInflater.from(mcontext);

   params.format = PixelFormat.RGBA_8888;
   phoneView=inflate.inflate(R.layout.phone_alert,null);
   wm.addView(phoneView, params);
   Log.e("TAG","响铃:来电号码"+incomingNumber);
   Log.e("TAG","响铃:======"+Thread.currentThread().getName());
   //输出来电号码
   break;
      }
    }
  };
  };
