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

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

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

 <receiver android:name="com.cloud.adapter.myview.PhoneReceiver">      <intent-filter>        <action android:name="android.intent.action.PHONE_STATE"/>        <action android:name="android.provider.Telephony.SMS_RECEIVED"/>        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />      </intent-filter>    </receiver>

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。

 <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />

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"?>  <com.cloud.adapter.myview.MyLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  android:layout_width="300dp"  android:layout_height="200dp"  android:orientation="vertical"  android:layout_gravity="center"  android:id="@+id/rootview"  >  <LinearLayout  android:background="@drawable/top_background"  android:layout_width="300dp"  android:layout_height="100dp"  android:orientation="vertical"  android:layout_gravity="center"  android:gravity="center"  >  <TextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:text="陆XX"    android:textSize="26sp"    />  <TextView    android:layout_marginTop="5dp"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:textSize="16sp"    android:text="系统运行科科长"    />  </LinearLayout>  <LinearLayout    android:background="@drawable/bottom_background"    android:layout_width="300dp"    android:layout_height="100dp"    android:orientation="vertical"    android:layout_gravity="center"    android:gravity="center"    >    <TextView      android:textColor="#fff"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:text="公司本部-信息中心-系统运营科"      android:textSize="20sp"      />    <TextView      android:layout_marginTop="10dp"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:textSize="20sp"      android:textColor="#fff"      android:text="XXX有限公司"      android:layout_marginBottom="10dp"      />  </LinearLayout>  </com.cloud.adapter.myview.MyLinearLayout>

使用到两个背景shape

 <?xml version="1.0" encoding="utf-8"?>  <shape xmlns:android="http://schemas.android.com/apk/res/android"  android:shape="rectangle">  <corners android:topLeftRadius="20dp"    android:topRightRadius="20dp"    />  <solid android:color="@color/colorPrimary"/>  </shape>  <?xml version="1.0" encoding="utf-8"?>  <shape xmlns:android="http://schemas.android.com/apk/res/android"  android:shape="rectangle">  <corners android:bottomLeftRadius="20dp"    android:bottomRightRadius="20dp"    />  <solid android:color="#f44"/>  </shape>
