Question

我正在尝试接收来电号码。我搜索并找到了这个 Retrieve incoming call's phone number in Android。我的问题是我无法在4.0.3以上版本中“传入号码”。如果我做错了什么，请指导我，或如何获得4.0.3以上版本的来电号码。提前致谢。这是代码：

TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(new PhoneStateListener(){
   public void onCallStateChanged(int state, String incomingNumber) {
       super.onCallStateChanged(state, incomingNumber);
          switch (state) {
              // not getting incoming number in latest version of android
              Log.e(Utils.TAG, "incomingNumber: "+incomingNumber);
          }
    }
},PhoneStateListener.LISTEN_CALL_STATE);

Answer 1

在清单中创建一个接收器：

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

添加此权限：

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

创建广播接收器：

public class PhoneState extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE); 

        switch (tm.getCallState()) {

            case TelephonyManager.CALL_STATE_RINGING:
                    String phoneNr= intent.getStringExtra("incoming_number");
                    Toast.makeText(context, phoneNr,Toast.LENGTH_LONG).show();
                    break;
        } 
    }
}

Answer 2

我遇到了同样的问题。修复了以下代码：

if (ActivityCompat.checkSelfPermission(this,
    Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]
    {Manifest.permission.READ_PHONE_STATE},3);
}
