在Android内部存储器中存储gif图像

问题描述

我对android很陌生.我想将图像保存到内存中，然后再从内存中检索图像并将其加载到图像视图中.我已使用以下代码成功将图像存储在内部存储器中:

I am quite new to android. I want to save image to internal memory and later retrieve the image from internal memory and load it to image view. I have successfully stored the image in internal memory using the following code :

void saveImage() {
    String fileName="img"+ cnt +".jpg";
    //File file=new File(fileName);
    try
    {

       FileOutputStream fOut=openFileOutput(fileName, MODE_PRIVATE);
       bmImg.compress(Bitmap.CompressFormat.JPEG, 100, fOut);

    }
    catch (Exception e)
    {
       e.printStackTrace();
    }
}

此代码用于保存jpg图像.如果我要保存gif图像，该怎么办?请帮我.我只能看到jpg和png的选项.

This code is for saving the jpg image. If I want to save a gif image how can i do that?? Please help me. I can see the options for only jpg and png.

推荐答案

位图仅适用于png，jpg等，并且gif是图像列表，因此您必须将其作为二进制文件使用并使用 FileOutputStream 和write(byte[])

Bitmap only works with png, jpg etc, and gif is a list of images, so you have to work with it as a binary file and use FileOutputStream and write(byte[])
