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

 <?xml version="1.0" encoding="utf-8"?>
  
  
  
  
  
  
    
    
  

  

使用到两个背景shape

 <?xml version="1.0" encoding="utf-8"?>
  
  
  
  

  <?xml version="1.0" encoding="utf-8"?>
