Android监听系统来电并弹出提示窗口
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>
