的Android狀態欄顏色在Embarcadero的RAD Studio中，C++

Question

編輯：

我設法使用此代碼

ANativeActivity_setWindowFlags(PANativeActivity(System::DelphiActivity), 
TJWindowManager_LayoutParams::JavaClass->FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS, 
TJWindowManager_LayoutParams::JavaClass->FLAG_TRANSLUCENT_STATUS); 

仍然不刪除狀態欄的當前背景（與導航欄也意外背景）知道如何添加新的背景顏色

這是行不通的：

_di_JWindow androidWindow = SharedActivity()->getWindow(); 
androidWindow->setStatusBarColor(17170432);

原帖：

我試圖用着色FireMonkey/RAD Studio中製作一個Android應用程序的狀態欄。

爲了實現它在Java中，我通常使用此代碼：

Window window = activity.getWindow(); 
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); 
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); 
window.setStatusBarColor(activity.getResources().getColor(R.color.my_statusbar_color)); 

在RAD Studio在我試圖做這樣的

首先，我包括頭的Android庫：

#ifdef __ANDROID__ 
#include <FMX.Helpers.Android.hpp> 
#include <Androidapi.JNIBridge.hpp> 
#include <Androidapi.JNI.Os.hpp> 
#include <Androidapi.JNI.JavaTypes.hpp> 
#include <Androidapi.JNI.GraphicsContentViewText.hpp> 
#include <Androidapi.JNI.Util.hpp> 
#include <Androidapi.JNI.App.hpp> 
#include <Androidapi.JNI.Embarcadero.hpp> 
#include <Androidapi.Jni.hpp> 
#endif 

然後當我試圖打電話時：

JWindow androidWindow = JNativeActivity::getWindow(); 

我得到像下面這樣超過100個錯誤：

    Androidapi.JNI.GraphicsContentViewText.hpp(18837): unimplemented pure virtual method 'getAllowEnterTransitionOverlap' in 'JWindow' 

這是我用C++的第一步，所以我不知道我這樣做是正確的。

你沒有正確使用Embarcadero的JNI包裝類。翻譯一下會更喜歡這個：

_di_JActivity activity = SharedActivity(); 
// or: _di_JActivity activity = TAndroidHelper::Activity; 

_di_JWindow window = activity->getWindow(); 
window->clearFlags(TJWindowManager_LayoutParams::JavaClass->FLAG_TRANSLUCENT_STATUS); 
window->addFlags(TJWindowManager_LayoutParams::JavaClass->FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); 
window->setStatusBarColor(activity->getResources()->getColor(...)); 
// I don't know how to translate R.color.my_statusbar_color 

然而，隨着中說，英巴卡迪諾的JWindow接口的定義不包括Window.setStatusBarColor()方法這是在API等級21加（安卓5，棒糖）。因此，除非您在自己的代碼中爲Window類手動定義了自己的JNI接口，否則在C++ Builder中將無法調用setStatusBarColor()，除非您訴諸於Java代碼中的調用是由您的C++調用的代碼或使用反射。
