Question

如何从Android应用程序拨打未接来电到指定号码。我试过这个但它会启动一个电话并等待呼叫终止。我希望电话响一次然后停止。请帮帮我。

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:123456789"));
startActivity(callIntent);

从Android应用程序拨打未接来电到指定号码

你可以实现但不能保证（如果其他人立即接到电话）！你的计算1环需要多少时间。启动Thread/Timer，然后调用此方法结束通话！

private void mEndCall() {
        try {
        String serviceManagerName = "android.os.ServiceManager";
        String serviceManagerNativeName = "android.os.ServiceManagerNative";
        String telephonyName = "com.android.internal.telephony.ITelephony";

        Class telephonyClass;
        Class telephonyStubClass;
        Class serviceManagerClass;
        Class serviceManagerStubClass;
        Class serviceManagerNativeClass;
        Class serviceManagerNativeStubClass;

        Method telephonyCall;
        Method telephonyEndCall;
        Method telephonyAnswerCall;
        Method getDefault;

        Method[] temps;
        Constructor[] serviceManagerConstructor;

        // Method getService;
        Object telephonyObject;
        Object serviceManagerObject;

        telephonyClass = Class.forName(telephonyName);
        telephonyStubClass = telephonyClass.getClasses()[0];
        serviceManagerClass = Class.forName(serviceManagerName);
        serviceManagerNativeClass = Class.forName(serviceManagerNativeName);

        Method getService = // getDefaults[29];
                serviceManagerClass.getMethod("getService", String.class);

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

        Binder tmpBinder = new Binder();
        tmpBinder.attachInterface(null, "fake");

        serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);
        IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");
        Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);

        telephonyObject = serviceMethod.invoke(null, retbinder);
        //telephonyCall = telephonyClass.getMethod("call", String.class);
        telephonyEndCall = telephonyClass.getMethod("endCall");
        //telephonyAnswerCall = telephonyClass.getMethod("answerRingingCall");

        telephonyEndCall.invoke(telephonyObject);

    } catch (Exception e) {
        e.printStackTrace();
        Log.e("error",
                "FATAL ERROR: could not connect to telephony subsystem");

    }
}

错过了在android中的后台调用
