这是最新的代码，它也适用于Android P，因为它具有官方API(在此处)：

在清单中，添加以下内容：

在代码中，使用以下代码：

Java的：

@SuppressLint("PrivateApi")

public static boolean endCall(Context context) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {

final TelecomManager telecomManager = (TelecomManager) context.getSystemService(Context.TELECOM_SERVICE);

if (telecomManager != null && ContextCompat.checkSelfPermission(context, Manifest.permission.ANSWER_PHONE_CALLS) == PackageManager.PERMISSION_GRANTED) {

telecomManager.endCall();

return true;

}

return false;

}

//use unofficial API for older Android versions, as written here: https://stackoverflow.com/a/8380418/878126

try {

final Class> telephonyClass = Class.forName("com.android.internal.telephony.ITelephony");

final Class> telephonyStubClass = telephonyClass.getClasses()[0];

final Class> serviceManagerClass = Class.forName("android.os.ServiceManager");

final Class> serviceManagerNativeClass = Class.forName("android.os.ServiceManagerNative");

final Method getService = serviceManagerClass.getMethod("getService", String.class);

final Method tempInterfaceMethod = serviceManagerNativeClass.getMethod("asInterface", IBinder.class);

final Binder tmpBinder = new Binder();

tmpBinder.attachInterface(null, "fake");

final Object serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);

final IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");

final Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);

final Object telephonyObject = serviceMethod.invoke(null, retbinder);

final Method telephonyEndCall = telephonyClass.getMethod("endCall");

telephonyEndCall.invoke(telephonyObject);

return true;

} catch (Exception e) {

e.printStackTrace();

LogManager.e(e);

}

return false;

}

或在科特林：

@SuppressLint("PrivateApi")

fun endCall(context: Context): Boolean {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {

val telecomManager = context.getSystemService(Context.TELECOM_SERVICE) as TelecomManager

if (ContextCompat.checkSelfPermission(context, Manifest.permission.ANSWER_PHONE_CALLS) == PackageManager.PERMISSION_GRANTED) {

telecomManager.endCall()

return true

}

return false

}

//use unofficial API for older Android versions, as written here: https://stackoverflow.com/a/8380418/878126

try {

val telephonyClass = Class.forName("com.android.internal.telephony.ITelephony")

val telephonyStubClass = telephonyClass.classes[0]

val serviceManagerClass = Class.forName("android.os.ServiceManager")

val serviceManagerNativeClass = Class.forName("android.os.ServiceManagerNative")

val getService = serviceManagerClass.getMethod("getService", String::class.java)

val tempInterfaceMethod = serviceManagerNativeClass.getMethod("asInterface", IBinder::class.java)

val tmpBinder = Binder()

tmpBinder.attachInterface(null, "fake")

val serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder)

val retbinder = getService.invoke(serviceManagerObject, "phone") as IBinder

val serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder::class.java)

val telephonyObject = serviceMethod.invoke(null, retbinder)

val telephonyEndCall = telephonyClass.getMethod("endCall")

telephonyEndCall.invoke(telephonyObject)

return true

} catch (e: Exception) {

e.printStackTrace()

return false

}

}
