ANDROID 通过监听来电去电，并弹出悬浮窗

时间：2024-04-22 17:34:24

要监听android打电话和接电话，有一种的是通过新建一个Receiver继承自BroadcastReceiver。

还有一种也可通过PhoneStateListener来实现。今天就说说后面一种，废话不说了，直接上代码

public class TelListener extends PhoneStateListener {
         
        private Context context;
        private WindowManager wm;//系统管理
        private TextView tv;//悬浮窗文本
        private Boolean isInComing=false;//标记是否为来电
        public TelListener(Context context){
                this.context = context;
        }
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
                switch(state)
                {
                case TelephonyManager.CALL_STATE_RINGING://此时为响铃状态
                    {
                        isInComing=true;//如果有响铃状态，则表示此时为来电

                        //以下代码为悬浮窗显示来电号码

                        //定义窗口布局

                        wm = (WindowManager)context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE); 

                        WindowManager.LayoutParams params = new WindowManager.LayoutParams(); 

                        //设置窗口布局居于所有之上

                        params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY; 

                        //使窗口失去焦点

                        params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
                        params.width = WindowManager.LayoutParams.WRAP_CONTENT; 

                        params.height = WindowManager.LayoutParams.WRAP_CONTENT; 

                        //背景透明

                        params.format = PixelFormat.RGBA_8888;
                        tv = new TextView(context);
                        String comingNum=  GetInComingNumber();
                        tv.setTextSize(40);
                        tv.setText("来电"+comingNum);
                        wm.addView(tv, params);//添加到系统窗口中。
                    }break;
                case TelephonyManager.CALL_STATE_OFFHOOK: //如果处于忙时状态
                    {
                        if(!isInComing)//如果非来电状态，则标记为去电
                        {
                            if(wm != null)
                                wm.removeView(tv);

                            //以下代码为悬浮窗显示去电号码

                            wm = (WindowManager)context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE); 
                            WindowManager.LayoutParams params = new WindowManager.LayoutParams(); 
                            params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY; 
                            params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
                            params.width = WindowManager.LayoutParams.WRAP_CONTENT; 
                            params.height = WindowManager.LayoutParams.WRAP_CONTENT; 
                            params.format = PixelFormat.RGBA_8888;
                            tv = new TextView(context);
                            tv.setTextSize(40);
                            //获取实际去电号码，此处使用自定义方法，（这边去电号码自己想办法保存）
                            String outcomingNum=AppData.getRealNum();
                            tv.setText("去电" + outcomingNum);
                            wm.addView(tv, params);
                            isInComing=false;//标记为非来电
                        }
                    }break;
                case TelephonyManager.CALL_STATE_IDLE:
                    {
                        if(wm != null && tv!=null)
                            wm.removeView(tv);
                    }break;
                }
                super.onCallStateChanged(state, incomingNumber);
        }
}

当然了，虽然代码是OK了，但是记得配置好权限。

1
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

虽然如此，既然是弹出悬浮窗，那也该配置下弹出悬浮窗的权限吧。

1
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

都好了，那最重要的一步可别忘记了，在启动的时候添加监听，并且注册广播。

TelephonyManager telM = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
      //设置监听
      telM.listen(new TelListener(this.getContext()), PhoneStateListener.LISTEN_CALL_STATE);

还要在AndroidManifest.xml中注册广播接收类

<receiver android:name=".PhoneBootReceiver">
            <intent-filter>
                    <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
    </receiver>

如果想要接收开机广播，然后在接收到广播后注册来电监听。接收开机广播需要有“RECEIVE_BOOT_COMPLETED”权限，AndroidManifest.xml 中申明如下

1
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

其实android API本身是无法监听去电的，这只是一种转弯的方法。。

PS：在转个弯，你就可以实现来电归属地查询了。。

目前我的处理方式是接收开机广播，然后在接收到广播后注册来电监听。接收开机广播需要有“android.permission.RECEIVE_BOOT_COMPLETED”权限，manifest中申明如下
