问题描述

我想我的位图图像存储到项目目录。我怎么能有机会到我的项目文件夹或什么是我的项目文件夹的地址？

I want to store my Bitmap image into project directory. How can I have access to my project folder or what is the address of my project folder?

推荐答案

您必须把图像中的 RES /绘制文件夹中。 R.drawable.name_of_image （为 name_of_image.png 或<$ C $：那么，您可以通过使用访问它们C> name_of_image.jpg ）。

You have to put the images in the res/drawable folder. Then, you can access them by using: R.drawable.name_of_image (for name_of_image.png or name_of_image.jpg).

如果您希望通过自己原来的名字来访问它们，你最好将它们保存在资产文件夹中。然后，您可以通过使用访问它们的 AssetManager ：

If you want to access them by their original name, you better save them in the assets folder. Then, you can access them by using the AssetManager:

AssetManager am = getResources().getAssets();
try {
    InputStream is = am.open("image.png");
    // use the input stream as you want
} catch (IOException e) {
    e.printStackTrace();
}

如果你想保存一个编程生成的图像，你可以这样做：

If you want to save a programatically created image, you can do:

try {
       FileOutputStream out = new FileOutputStream(context.getFilesDir().getAbsolutePath()+"/imagename.png");
       bmp.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
       e.printStackTrace();
}

您不能将其保存到您的项目目录。我建议你​​阅读有关如何Android包工作的文件，因为它似乎你不明白。

You can't save it to your project directory. I recommend you to read the documentation about how android packages work, because it seems you don't understand.
