Android監(jiān)聽系統(tǒng)來電并彈出提示窗口

本篇文章主要介紹了Android監(jiān)聽系統(tǒng)來電并彈出提示窗口，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

1.問題

項目中有自己企業(yè)的通訊錄，但是在應(yīng)用中撥打公司通訊錄的聯(lián)系人，由于手機(jī)通訊錄中沒有相應(yīng)的信息，只顯示一串電話號

2 .目的

監(jiān)聽系統(tǒng)來電，獲取到電話號碼，通過調(diào)用接口，查詢出來相應(yīng)電話號碼的詳細(xì)信息，并彈出系統(tǒng)懸浮框，給用戶提示。

3.實現(xiàn)

首先注冊廣播監(jiān)聽系統(tǒng)來電。監(jiān)聽系統(tǒng)來電需要、注冊相應(yīng)的權(quán)限

代碼地址：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" />

自定義廣播去監(jiān)聽系統(tǒng)來電

 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)){
      //如果是去電（撥出）
      Log.e("TAG","撥出");
    }else{

      Log.e("TAG","來電");
      TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
      tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
      //設(shè)置一個監(jiān)聽器
    }
  }


  private PhoneStateListener listener=new PhoneStateListener(){

    @Override
    public void onCallStateChanged(int state, final String incomingNumber) {
      // TODO Auto-generated method stub
      //state 當(dāng)前狀態(tài) incomingNumber,貌似沒有去電的API
      super.onCallStateChanged(state, incomingNumber);
      switch(state){
        case TelephonyManager.CALL_STATE_IDLE:
          Log.e("TAG","掛斷");

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

          break;
        case TelephonyManager.CALL_STATE_RINGING:

          //輸出來電號碼
          Log.e("TAG","響鈴:來電號碼"+incomingNumber);
          Log.e("TAG","響鈴:======"+Thread.currentThread().getName());

          break;
      }
    }
  };
  };

需要靜態(tài)注冊廣播

 <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>

其次在注冊完，廣播之后我們需要在監(jiān)聽到系統(tǒng)的來電之后，后獲取到電話號之后去請求接口，獲取數(shù)據(jù)。并彈出系統(tǒng)懸浮框。

注意：在彈出系統(tǒng)懸浮框的時候需要注冊權(quán)限，并且檢查應(yīng)用的允許彈出懸浮框權(quán)限是否開啟。

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

在監(jiān)聽中的 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);

自定義一個布局文件，作為要添加的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="陸XX"
    android:textSize="26sp"
    />
  <TextView
    android:layout_marginTop="5dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="16sp"
    android:text="系統(tǒng)運(yùn)行科科長"
    />
  </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-系統(tǒng)運(yùn)營科"
      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>

使用到兩個背景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>
