Android监听系统来电并弹出提示窗口
2020年02月14日

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>
