Answer 1

此代码将阻止您的所有通话(INCOMING AND OUTGOING)

import java.lang.reflect.Method;

import android.content.Context;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;

import com.CallLogApp.helper.BlockNumberHelper;
import com.CallLogApp.util.UDF;
import com.android.internal.telephony.ITelephony;

public class CustomPhoneStateListener extends PhoneStateListener {

    //private static final String TAG = "PhoneStateChanged";
    Context context;
    public CustomPhoneStateListener(Context context) {
        super();
        this.context = context;
    }

    @Override
    public void onCallStateChanged(int state, String outGoingNumber) {
        super.onCallStateChanged(state, outGoingNumber);

        switch (state) {
            case TelephonyManager.CALL_STATE_IDLE:
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                endCallIfBlocked(outGoingNumber);
                break;
            case TelephonyManager.CALL_STATE_RINGING:
                break;
            default:
                break;
        }

     }

     private void endCallIfBlocked(String outGoingNumber) {
        try {
            // Java reflection to gain access to TelephonyManager's
            // ITelephony getter
            TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            Class<?> c = Class.forName(tm.getClass().getName());
            Method m = c.getDeclaredMethod("getITelephony");
            m.setAccessible(true);
            com.android.internal.telephony.ITelephony telephonyService = (ITelephony) m.invoke(tm);  

            if (new BlockNumberHelper(context).isBlocked(outGoingNumber))
            {
                telephonyService = (ITelephony) m.invoke(tm);
                telephonyService.silenceRinger();
                telephonyService.endCall();
            }


        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

在此CALL_STATE_OFFHOOK状态会打电话的时候,您的通话将要连接每一次,当你接收的来电

没有任何方法可以让你知道天气是来电还是来电

但是你可以在两个场景中结束呼叫
