PhoneStateListener 沒有給出撥打/呼叫的號碼

Question

根據文檔，PhoneStateListener 是一個 class 處理電話 state 更改，onCallStateChanged 方法應獲取 2 個參數，state（整數）和字符串。

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");
    }
}

上面的代碼是我的 PhoneStateListener class，我從服務中調用它：

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");

    }
}

我從我的主要活動開始服務，但是我從來沒有得到號碼（它不是 NULL，但它是一個空字符串）。 我見過有人使用廣播接收器的例子，但我不明白為什么文檔聲明該號碼應該可以使用 PhoneStateListener。

這是我的清單：

<?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>

Answer 1

以下是我獲取撥打號碼/來電號碼的方法：

1. 這是我的主要活動：

   package com.eddieharari.shippit；

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

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

   公共 class MainActivity 擴展 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(); }

   }

請注意，您需要在清單和運行時詢問權限，如您在此處看到的...不需要廣播偵聽器，只有 phonestate 偵聽器...這是我的手機 state 偵聽器 class：

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;
        }
    }
}
