如何从来电中获取电话号码？

Question

安卓有来电怎么获取电话号码？

Answer 1

做一个

Broadcast receiver

说

ServiceReceiver

在Manifest中分配它的动作。

<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 已使用 Incoming number 参数覆盖

onCallStateChanged()

。就是这样。

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传出的电话号码。

清单中要包含的内容：

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>

---

BroadcastReceiver 类中包含的内容:

    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");
                }   
            }   
        }
    }

Answer 3

这一定能帮到你。

这里是一个实现，如果它是来电，它将允许您检索电话号码作为来电号码，并且当呼叫结束时 - 请注意 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 onCreate 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

你可以在这里找到解决方案

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

Answer 5

如果您正在使用 InCallService 并且您有一个 Call 对象，那么您可以使用以下代码快速获取来电号码

if (call.getDetails().getGatewayInfo()!=null){

number=call.getDetails().getGatewayInfo().getOriginalAddress().getSchemeSpecificPart();}

else {  
number=mainCall.getDetails().getHandle().getSchemeSpecificPart();}

这里调用的是

android.telecom.Call

包中的对象，'number'是一个字符串类型变量。

希望对您有所帮助

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，从

Android 9

开始阅读来电号码，您必须请求此权限

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

Answer 7

从 Android 9 开始明确要求两个运行时权限。

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

现在在里面

onReceive

我们可以从意图中提取电话号码

String number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER); 但问题就在这里：

onReceive

 方法为每个状态调用两次，一次 EXTRA_INCOMING_NUMBER 空白，另一次填充电话号码。
所以如果你想提取电话号码你必须得到正确的值你可以这样做，只需返回包含 null ..

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