如何在Android中以编程方式拒绝通话

首先创建此接口：

  public interface ITelephony {        boolean endCall();        void answerRingingCall();        void silenceRinger();  }

然后创建扩展BroadcastReceiver的此类

public class IncomingCallReceiver extends BroadcastReceiver {    private ITelephony telephonyService;    private String blacklistednumber = "+458664455";    @Override    public void onReceive(Context context, Intent intent) {       TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);       try {         Class c = Class.forName(tm.getClass().getName());         Method m = c.getDeclaredMethod("getITelephony");         m.setAccessible(true);         ITelephony telephonyService = (ITelephony) m.invoke(tm);         Bundle bundle = intent.getExtras();         String phoneNumber = bundle.getString("incoming_number");         Log.e("INCOMING", phoneNumber);         if ((phoneNumber != null) && phoneNumber.equals(blacklistednumber)) {  telephonyService.silenceRinger(); telephonyService.endCall(); Log.e("HANG UP", phoneNumber);         }       } catch (Exception e) {         e.printStackTrace();       }}

这只会阻止该单个电话号码，但是您明白了。

在清单中添加以下内容：

<receiver android:name=".IncomingCallReceiver">    <intent-filter android:priority="999">        <action android:name="android.intent.action.PHONE_STATE" />    </intent-filter></receiver><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.MODIFY_PHONE_STATE" /><uses-permission android:name="android.permission.CALL_PHONE" /><uses-permission android:name="android.permission.PROCESS_INCOMING_CALLS" />
