如何从来电的电话中获取电话号码

Question

当Android中有一个来电时，我如何获得电话号码？

Answer 1

使Broadcast receiver说ServiceReceiver在清单中分配其动作。

<receiver android:name=".ServiceReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>

将PhoneStateListener添加到您的TelephonyManager，phonEstateListener具有带有传入号码参数的onCallStateChanged()。多数民众赞成在。

servicereceiver.java

public class ServiceReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(final Context context, Intent intent) {
        TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        telephony.listen(new PhoneStateListener(){
            @Override
            public void onCallStateChanged(int state, String incomingNumber) {
                super.onCallStateChanged(state, incomingNumber);
                System.out.println("incomingNumber : "+incomingNumber);
            }
        },PhoneStateListener.LISTEN_CALL_STATE);
    }
}

以下解决方案帮助我检索了传入和发出的电话号码。

在清单中包括的东西：

1）许可：

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

2）广播接收器：

<receiver android:name=".AnswerCallBroadcastReceiver">
        <intent-filter> 
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
</receiver>

---

在Broadcastreceiver类中包括的东西：

    public class AnswerCallBroadcastReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            if(arg1.getAction().equals("android.intent.action.PHONE_STATE")){
                String state = arg1.getStringExtra(TelephonyManager.EXTRA_STATE);
                if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){
                    Log.d(TAG, "Inside Extra state off hook");
                    String number = arg1.getStringExtra(TelephonyManager.EXTRA_PHONE_NUMBER);
                    Log.e(TAG, "outgoing number : " + number);              
                }       
                else if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)){   
                    Log.e(TAG, "Inside EXTRA_STATE_RINGING");
                    String number = arg1.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
                    Log.e(TAG, "incoming number : " + number);
                }
                else if(state.equals(TelephonyManager.EXTRA_STATE_IDLE)){
                    Log.d(TAG, "Inside EXTRA_STATE_IDLE");
                }   
            }   
        }
    }

这肯定会帮助您。

这是一个实现，如果它是传入的电话，则可以检索电话号码，也可以在呼叫完成时检索 - 注意handler（）代码。

private class PhoneCallListener extends PhoneStateListener {
private boolean isPhoneCalling = false;
@Override
public void onCallStateChanged(int state, String incomingNumber) {
    if (TelephonyManager.CALL_STATE_RINGING == state) {
        // phone ringing
        Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
    }
    if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
        // active
        Log.i(LOG_TAG, "OFFHOOK");
        isPhoneCalling = true;
    }
    if (TelephonyManager.CALL_STATE_IDLE == state) {
        // run when class initial and phone call ended, need detect flag
        // from CALL_STATE_OFFHOOK
        Log.i(LOG_TAG, "IDLE number");
        if (isPhoneCalling) {
            Handler handler = new Handler();
            //Put in delay because call log is not updated immediately when state changed
            // The dialler takes a little bit of time to write to it 500ms seems to be enough
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    // get start of cursor
                      Log.i("CallLogDetailsActivity", "Getting Log activity...");
                        String[] projection = new String[]{Calls.NUMBER};
                        Cursor cur = getContentResolver().query(Calls.CONTENT_URI, projection, null, null, Calls.DATE +" desc");
                        cur.moveToFirst();
                        String lastCallnumber = cur.getString(0);
                }
            },500);
            isPhoneCalling = false;
        }
    }
} 

，然后在您的ongreate或onstartCommand代码中添加并初始化侦听器：

  PhoneCallListener phoneListener = new PhoneCallListener();
TelephonyManager telephonyManager = (TelephonyManager) this
        .getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(phoneListener,
        PhoneStateListener.LISTEN_CALL_STATE);

Answer 4

您可以在此处找到解决方案

Bundle bundle = intent.getExtras();
String phoneNr= bundle.getString("incoming_number");

Answer 5

如果您使用的是incallService并且有一个呼叫对象，则可以通过使用以下代码

快速获取传入的电话号码

if (call.getDetails().getGatewayInfo()!=null){
number=call.getDetails().getGatewayInfo().getOriginalAddress().getSchemeSpecificPart();}
else {  
number=mainCall.getDetails().getHandle().getSchemeSpecificPart();}

这里调用是android.telecom.Call软件包中的对象，"数字"是字符串类型变量。

希望这对您有帮助。

Answer 6

上面的答案是正确的，但是，不要忘记权限
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

注意，启动表格 Android 9要读取传入电话号码，您必须请求此许可
<uses-permission android:name="android.permission.READ_CALL_LOG" />

Answer 7

来自Android 9明确要求两个运行时许可。

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

现在在onReceive中，我们可以从意图中提取电话号码

String number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

但是捕获在这里： onReceive方法针对每个状态进行两次调用，一个带有空白的Extra_incoming_number，另一个带有电话号码。因此，如果要提取电话号码，则必须获得正确的值，只需返回包含空的null ..

 @Override
public void onReceive(Context context, Intent intent) {
 if(!intent.hasExtra(TelephonyManager.EXTRA_INCOMING_NUMBER))
            return;
   //....Further TODO
}
