Android 系统广播 打电话状态

转载请说明出处 

最近在做公司新产品的设计，想到广播效果设计加入到项目应该挺不错的，所以我们想将这个设计理念加入到我们的产品中。

电话状态实例

  要先创建一个新Activity

package com.dzz.android20_phonest;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.telephony.TelephonyManager;import android.util.Log;/** * Created by 朝花偏不夕拾 on 2017/2/7. */public class MyPhoneState extends BroadcastReceiver{    @Override    public void onReceive(Context context, Intent intent) {        if("android.intent.action.PHONE_STATE".equals(intent.getAction())){            //获取电话号码            String number=intent.getStringExtra("incoming_number");            Log.i("test","有电话进来了"+number);            //获取电话状态            //电话管理者            TelephonyManager tm= (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);            int state= tm.getCallState();            switch (state){                case TelephonyManager.CALL_STATE_RINGING://来电                    Log.i("test","来电话了_前");                    break;                case TelephonyManager.CALL_STATE_OFFHOOK://接听                    Log.i("test","通话中_中");                    break;                case TelephonyManager.CALL_STATE_IDLE:   //挂断                    Log.i("test","挂断了_后");                    break;            }        }    }}

清单文件中配置 和加权限

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.dzz.android20_phonest">

<!--读取电话状态权限-->    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

    <application android:allowBackup="true" android:icon="@mipmap/ic_launcher"        android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme">        <activity android:name=".MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>

需要配置下        <receiver android:name=".MyPhoneState">              <intent-filter>                <action android:name="android.intent.action.PHONE_STATE"></action>            </intent-filter>        </receiver>

    </application></manifest>

test: 结果

注：BroadcastReceiver  生命周期有 onReceive 一个
