Android監聽系統來電並彈出提示視窗

Android監聽系統來電並彈出提示視窗

1.問題

專案中有自己企業的通訊錄,但是在應用中撥打公司通訊錄的聯絡人,由於手機通訊錄中沒有相應的資訊,只顯示一串電話號

2 .目的

監聽系統來電,獲取到電話號碼,通過呼叫介面,查詢出來相應電話號碼的詳細資訊,並彈出系統懸浮框,給使用者提示。

3.實現

首先 註冊廣播監聽系統來電。監聽系統來電需要、註冊相應的許可權

程式碼地址: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" />

自定義廣播去監聽系統來電


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);
//設定一個監聽器
}
}
private PhoneStateListener listener=new PhoneStateListener(){
@Override
public void onCallStateChanged(int state, final String incomingNumber) {
// TODO Auto-generated method stub
//state 當前狀態 incomingNumber,貌似沒有去電的API
super.onCallStateChanged(state, incomingNumber);
switch(state){
case TelephonyManager.CALL_STATE_IDLE:
Log.e("TAG","結束通話");
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;
}
}
};
};

需要靜態註冊廣播


<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>

其次在註冊完,廣播之後我們需要在監聽到系統的來電之後,後獲取到電話號之後去請求介面,獲取資料。並彈出系統懸浮框。

注意:在彈出系統懸浮框的時候需要註冊許可權,並且檢查應用的允許彈出懸浮框許可權是否開啟。


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

在監聽中的 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);

自定義一個佈局檔案,作為要新增的View,佈局檔案如下


<?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="系統執行科科長"
/>
</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-資訊中心-系統運營科"
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>
