解决方法
首先创建此接口：
public interface ITelephony {
boolean endCall();
void answerRingingCall();
void silenceRinger();
}
然后创建扩展BroadcastReceiver的这个类
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();
}
}
这只能阻止那个单一的电话号码,但你明白了.
在你的清单中添加：
<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" />
