【问题描述】：

根据文档，PhoneStateListener 是一个处理手机状态变化的类， onCallStateChanged 方法应该获取 2 个参数，状态（整数）和字符串 -> 电话号码。

package com.eddieharari.shippit;

import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

public class PhoneStateBcListener extends PhoneStateListener {
    @Override
    public void onCallStateChanged(int state,String phone) {

        switch (state) {
            case TelephonyManager.CALL_STATE_IDLE:
                Log.d("SHIPIT","Call State Idle");
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                Log.d("SHIPIT","Call State OffHook:");
                break;
            case TelephonyManager.CALL_STATE_RINGING:
                Log.d("SHIPIT","Call State Ringing:"+phone);
                break;
        }
        if (phone == null) {
            Log.d("SHIPPIT","Number is null");
        } else Log.d("SHIPPIT","Number is not Null");
    }
}

上面的代码是我的 PhoneStateListener 类，我从服务中调用它：

package com.eddieharari.shippit;

import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

public class GetCallService extends Service {
    TelephonyManager telephony;
    PhoneStateBcListener myListener = new PhoneStateBcListener();

    @Override
    public IBinder onBind(Intent i) {
        return null;
    }

    @Override
    public void onCreate() {
        Log.d("SHIPT","Inside Oncreate");
        Log.d("SHIPPIT","Started Receiver");
        telephony = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        telephony.listen(myListener, PhoneStateListener.LISTEN_CALL_STATE);
    }

    @Override
    public void onStart(Intent i, int start ) {
        Log.d("SHIPIT","Inside START");
    }
    @Override
    public void onDestroy() {
        Log.d("SHIPIT","Inside Ondestroy");

    }
}

我从我的主要活动开始服务，但是我从来没有得到号码（它不是 NULL，但它是一个空字符串）。我已经看到人们使用广播接收器的例子，但我不明白为什么文档声明该号码应该可以使用 PhoneStateListener。

这是我的清单：

<?xml version="1.0" encoding="utf-8"?>

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

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    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>
    <service
        android:name=".GetCallService"
        android:enabled="true" />
</application>

【问题讨论】：

我有一些进展，因为似乎有了新的 API 级别，我需要询问运行时的权限，但是即使我只能获得传入的号码而不是传出的号码，而且它也无法正常工作模拟器，仅在实际设备上...

【解决方案1】：

以下是我获取拨打号码/来电号码的方法：

这是我的主要活动：

包 com.eddieharari.shippit;

导入 androidx.appcompat.app.AppCompatActivity; 导入android.Manifest；导入android.content.Context；导入android.content.Intent；导入 android.content.IntentFilter；导入 android.content.pm.PackageManager；导入android.os.Bundle；

导入 android.telephony.PhoneStateListener; 导入 android.telephony.TelephonyManager；导入android.util.Log；

公共类 MainActivity 扩展 AppCompatActivity {

 TelephonyManager tm;
 PhoneStateListener mReceiver = new mPhoneStateListener();

 @Override
 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

     setContentView(R.layout.activity_main);
     if (checkSelfPermission(Manifest.permission.READ_PHONE_STATE) !=PackageManager.PERMISSION_GRANTED) {
         Log.d("SHIPIT","NOT HAVE PERMISSION FOR PHONE_STATE");
         requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE},0);} else Log.d("SHIPIT","HAVE THE PHONE STATE PERMISSIONS");
     if (checkSelfPermission(Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED) {
         Log.d("SHIPIT","NOT HAVE PERMISSION FOR CALL_LOG");
         requestPermissions(new String[]{Manifest.permission.READ_CALL_LOG},0);} else Log.d("SHIPIT","HAVE THE READ CALL LOG");

     tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
     tm.listen(mReceiver,mPhoneStateListener.LISTEN_CALL_STATE);


     Log.d("SHIPIT","Registered the receiver");

 }

 @Override
 protected  void onDestroy(){
     super.onDestroy();
 }

}

请注意，您需要在清单和运行时询问权限，如您在此处看到的那样...不需要广播侦听器，只有 phonestate 侦听器...这是我的电话状态侦听器类：

package com.eddieharari.shippit;

import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

public class mPhoneStateListener extends PhoneStateListener {
    @Override
    public void onCallStateChanged(int state, String number){
        switch (state) {
            case TelephonyManager.CALL_STATE_IDLE:
                Log.d("SHIPIT","State is IDLE");
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                Log.d("SHIPIT","State is OffHook:"+number);
                break;
            case TelephonyManager.CALL_STATE_RINGING:
                Log.d("SHIPIT","State is Ringing:"+number);
                break;
        }
    }
}
