我想挂断来电，检测到它，然后挂断。

问题是：这com.android.internal.telephony.ITelephony没有解决。

我试图将包添加com.android.internal.telephony到我的应用程序并创建接口：

package com.android.internal.telephony;

public interface ITelephony {      

    boolean endCall();     

    void answerRingingCall();      

    void silenceRinger(); 

}

但通话并未结束。

在这里，我检测到呼叫，显示toast（已显示），然后尝试挂断，但是正如我首先说的那样，com.android.internal.telephony.ITelephony在创建该程序包之前没有：

private class CallStateListener extends PhoneStateListener {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                // called when someone is ringing to this phone
                Toast.makeText(ctx, "Incoming: " + incomingNumber, Toast.LENGTH_LONG).show();
                 try{
                        TelephonyManager tm = (TelephonyManager) ctx.getSystemService(Context.TELEPHONY_SERVICE);
                        Class c = Class.forName(tm.getClass().getName());
                        Method m = c.getDeclaredMethod("getITelephony");
                        com.android.internal.telephony.ITelephony telephonyService = (com.android.internal.telephony.ITelephony) m.invoke(tm);  

                        telephonyService = (com.android.internal.telephony.ITelephony) m.invoke(tm);
                        telephonyService.silenceRinger();
                        telephonyService.endCall();
                    }catch (Exception e) {
                        e.printStackTrace();

                    }
                break;
            }
        }
    }
