我有一个 BroadcastReceiver，我知道如何拒绝来电。但是当我按下后退按钮时，我需要帮助拒绝来电，因为我的代码中有某种错误......

public class CallReceiveD extends BroadcastReceiver {
    private ITelephony telephonyService;
    public String phoneNumber;
    public Bundle extras;
    public TelephonyManager tm; 
    public Intent i;

    @Override
    public void onReceive(Context context, Intent intent) {
        i=intent;
        extras = intent.getExtras();
        if (extras != null) 
        {
            String state = extras.getString(TelephonyManager.EXTRA_STATE);

            if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
            {
                phoneNumber = extras.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
                Toast toast= Toast.makeText(context,phoneNumber, Toast.LENGTH_LONG);toast.show();
                tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); 
                try { 
                    Class c = Class.forName(tm.getClass().getName()); 
                    Method m = c.getDeclaredMethod("getITelephony"); 
                    m.setAccessible(true);

                    telephonyService = (ITelephony) m.invoke(tm);
                    // telephonyService.endCall(); 
                } catch (Exception e) { 
                    e.printStackTrace(); 
                }
            }
        }
    }

    //@Override
    public void onBackPressed() {
        telephonyService.endCall(); 
        return;
    }   
}

据我所知，您不能使用您用来拒绝呼叫的后退按钮 onreceive 事件，但是后退按钮按下功能我可以，如果您在广播接收 onReceive 之外使用它，它应该可以工作
