Java 如何将 com.android.internal.telephony.ITelephony 导入到 Android 应用程序

How to import com.android.internal.telephony.ITelephony to the Android application

提问by Yoda

I want to hang up incoming call I detect it and then I want to hang it up.

我想挂断来电我检测到它然后我想挂断它。

The problem is that this: com.android.internal.telephony.ITelephonyis not resolved.

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

I tried to adding package com.android.internal.telephonyto my application and create interface:

我尝试将包添加com.android.internal.telephony到我的应用程序并创建界面：

package com.android.internal.telephony;

public interface ITelephony {      

    boolean endCall();     

    void answerRingingCall();      

    void silenceRinger(); 

}

but the call is not ended.

但通话并没有结束。

Here I detect call, display toast(it is displayed) then try to hang up but as I said first there was no com.android.internal.telephony.ITelephonybefore I created that package:

在这里，我检测到呼叫，显示吐司（显示）然后尝试挂断，但正如我首先所说的那样，com.android.internal.telephony.ITelephony在创建该包之前没有：

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;
            }
        }
    }

The ITelephonyinterface is internal, so you cannot get a standard reference to it. You coulduse reflection all the way, i.e.

该ITelephony接口是内部的，因此您无法获得对它的标准引用。你可以一直使用反射，即

TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);

Method m1 = tm.getClass().getDeclaredMethod("getITelephony");
m1.setAccessible(true);
Object iTelephony = m1.invoke(tm);

Method m2 = iTelephony.getClass().getDeclaredMethod("silenceRinger"); 
Method m3 = iTelephony.getClass().getDeclaredMethod("endCall"); 

m2.invoke(iTelephony);
m3.invoke(iTelephony);

But either way those methods need the MODIFY_PHONE_STATEpermission, which can only be granted to system apps. So I'm afraid it won't work anyway.

但无论哪种方式，这些方法都需要MODIFY_PHONE_STATE权限，该权限只能授予系统应用程序。所以恐怕无论如何都行不通。

For kotlin:

对于科特林：

 val tm = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
 val m1 = tm::class.java.getDeclaredMethod("getITelephony")
 m1.setAccessible(true)
 val telephonyService = m1.invoke(tm)
 val m2 = telephonyService::class.java.getDeclaredMethod("silenceRinger")
 val m3 = telephonyService::class.java.getDeclaredMethod("endCall")

 m2.invoke(telephonyService)
 m3.invoke(telephonyService)
