如何在Android上获取Cocos2d-x的屏幕快照保存路径 [英] How to get screenshot saved path by Cocos2d-x on android

问题描述

我使用saveToFile方法保存屏幕截图，并检查CCLOG，它显示/data/data/com.xxx.xxx/files/xxx.png

I use saveToFile method to save screenshot, and I check CCLOG, it shows /data/data/com.xxx.xxx/files/xxx.png

但是，当我使用Java获取此文件时，它显示没有这样的文件或目录".... 我该怎么办?

However, when I use Java to get this file, it says "No such file or directory".... What can I do?

推荐答案

我也遇到了同样的问题.当我尝试renderTexture->saveToFile方法时，无法提交Java路径.没关系，我使用getWritablePath()或直接设置路径"/sdcard/Android/data/com.xxx.xxx/snapshot.jpg".
我还尝试根据 Facundo Olano 的建议解决此问题.但是CCImage仅构成纯黑色图像.
最后，我将这两种方法结合起来.首先，我用renderTexture->saveToFile制作图像:

I also had the same problem. When I try renderTexture->saveToFile method, I can't submit path to java. No matter, I used getWritablePath() or set the path directly "/sdcard/Android/data/com.xxx.xxx/snapshot.jpg".
I try also to solve this problem on the advice of Facundo Olano. But CCImage compose only solid black image.
Finally I combine this two methods. First, I make an image by renderTexture->saveToFile:

void MyScene::pressFaceBook()
{
    ...
    RenderTexture* renderTexture = RenderTexture::create(sharedImage->getBoundingBox().size.width, sharedImage->getBoundingBox().size.height, Texture2D::PixelFormat::RGBA8888);
    renderTexture->begin();
    sharedImage->visit();
    renderTexture->end();
    renderTexture->saveToFile("snapshot.jpg", Image::Format::JPG);
    const std::string fullpath = FileUtils::getInstance()->getWritablePath() + "snapshot.jpg";
    sharedImage->setVisible(false);
    this->runAction(Sequence::create(DelayTime::create(2.0f),
                                     CallFunc::create(std::bind(&MyScene::shareFaceBook, this, fullpath)),
                                     NULL));
}

然后我将initWithImageFile与传输的文件名一起使用:

And then I use initWithImageFile with the transferred file name:

void MyScene::shareFaceBook(const std::string& outputFile)
{
    const std::string joutputFile = "/sdcard/Android/data/com.xxx.xxx/snapshot.jpg";
    cocos2d::Image* img = new Image;
    img->initWithImageFile(fullpath);
    img->saveToFile(joutputFile);
    CC_SAFE_DELETE(img);
    singleton->shareFaceBook(joutputFile);
}

需要2秒的延迟才能捕获屏幕截图. 当然，必须用您的应用名称代替com.xxx.xxx.

A delay of 2 seconds is needed to capture the screenshot. Of course, instead com.xxx.xxx you must substitute your app name.
