C++11在Android NDK中已经支持了,本文主要介绍如何在NDK中添加C++11标准的支持。
在开源项目Cocos2d-x中,已经添加了C++11标准的支持。
1.修改Application.mk文件,添加NDK_TOOLCHAIN_VERSION
NDK_TOOLCHAIN_VERSION=4.8
APP_CPPFLAGS := -frtti -std=c++11
#include
#include
#include
using namespace::std;
#define LOG_TAG "cachetest"
#define LOGI(...) __android_log_print(ANDROID_LOG_INFO,LOG_TAG,__VA_ARGS__)
template
class MyArray
{
private:
vector m_Array;
public:
MyArray() { }
MyArray(const initializer_list& il)
{
// Manually populate the elements of the array from initializer_list x
for (auto x: il){ // use range-based for statement to iterate over the elements of the initializer list
m_Array.push_back(x); // push them into the array manually
}
}
void showContent()
{
//old way
LOGI("in old way");
for (std::vector::iterator itr = m_Array.begin(); itr != m_Array.end(); ++itr){
LOGI("%d",(*itr));
}
LOGI("in c++11 new way");
for (auto x: m_Array){ //x is readonly
LOGI("%d",x);
}
}
};
void test_cpp_new_version_11()
{
auto x = 1;//int x = 1;
int *p = nullptr;//int *p = NULL;
MyArray foo = { 3, 4, 6, 9 };
foo.showContent();
}
