Android監(jiān)聽(tīng)系統(tǒng)來(lái)電并彈出提示窗口
1.問(wèn)題
創(chuàng)新互聯(lián)建站專注為客戶提供全方位的互聯(lián)網(wǎng)綜合服務(wù)，包含不限于成都做網(wǎng)站、成都網(wǎng)站制作、成都外貿(mào)網(wǎng)站建設(shè)、白塔網(wǎng)絡(luò)推廣、微信小程序開(kāi)發(fā)、白塔網(wǎng)絡(luò)營(yíng)銷(xiāo)、白塔企業(yè)策劃、白塔品牌公關(guān)、搜索引擎seo、人物專訪、企業(yè)宣傳片、企業(yè)代運(yùn)營(yíng)等，從售前售中售后，我們都將竭誠(chéng)為您服務(wù)，您的肯定，是我們最大的嘉獎(jiǎng)；創(chuàng)新互聯(lián)建站為所有大學(xué)生創(chuàng)業(yè)者提供白塔建站搭建服務(wù)，24小時(shí)服務(wù)熱線：028-86922220，官方網(wǎng)址：www.cdcxhl.com
項(xiàng)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(méi)有相應(yīng)的信息，只顯示一串電話號(hào)
2 .目的
監(jiān)聽(tīng)系統(tǒng)來(lái)電，獲取到電話號(hào)碼，通過(guò)調(diào)用接口，查詢出來(lái)相應(yīng)電話號(hào)碼的詳細(xì)信息，并彈出系統(tǒng)懸浮框，給用戶提示。
3.實(shí)現(xiàn)
首先 注冊(cè)廣播監(jiān)聽(tīng)系統(tǒng)來(lái)電。監(jiān)聽(tīng)系統(tǒng)來(lái)電需要、注冊(cè)相應(yīng)的權(quán)限
代碼地址：https://github.com/sdsjk/phone_alert.git
自定義廣播去監(jiān)聽(tīng)系統(tǒng)來(lái)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(lái)電");
TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
//設(shè)置一個(gè)監(jiān)聽(tīng)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(méi)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(tīng)");
break;
case TelephonyManager.CALL_STATE_RINGING:
//輸出來(lái)電號(hào)碼
Log.e("TAG","響鈴:來(lái)電號(hào)碼"+incomingNumber);
Log.e("TAG","響鈴:======"+Thread.currentThread().getName());
break;
}
}
};
};
需要靜態(tài)注冊(cè)廣播
其次在注冊(cè)完，廣播之后我們需要在監(jiān)聽(tīng)到系統(tǒng)的來(lái)電之后，后獲取到電話號(hào)之后去請(qǐng)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(shí)候需要注冊(cè)權(quán)限，并且檢查應(yīng)用的允許彈出懸浮框權(quán)限是否開(kāi)啟。
在監(jiān)聽(tīng)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(gè)布局文件，作為要添加的View，布局文件如下
<?xml version="1.0" encoding="utf-8"?>
使用到兩個(gè)背景shape
<?xml version="1.0" encoding="utf-8"?><?xml version="1.0" encoding="utf-8"?>
