如何从Android的内部存储器读取图像? [英] How to read image from internal memory in android?

问题描述

我的内部存储器的屏幕快照，我已经保存了图像.
我想在图像视图中读取图像.那么如何获取图像路径或如何从内存中读取图像?请帮助我.

我尝试了一些代码，但是没有用:-

this screen shot of my internal memory storage which i save image already.
i want to read image in image view. so how to get path of image or how can i read image from internal memory? please help me..

i tried some code but its not working:-

 FileInputStream fis;
        String filePath = activity.getFilesDir().getPath();
         String path = data.get(position).get("product_image");
         fis = openFileInput(filePath+"/broccolicasserole.jpg");
         Bitmap      bitmapA = BitmapFactory.decodeStream(fis);
         producticon.setImageBitmap(bitmapA);

图像名称是从数据库获取的，例如:-data.get(position).get("product_image");
也可以尝试以下代码:-

image name is get from database like :-data.get(position).get("product_image");
also try this code also:-

  >  String filePath = activity.getFilesDir().getPath();
   File filePath1 =   imageLoader.DisplayImage(filePath+data.get(position).get("product_image"), producticon);

推荐答案

private String readFileFromInternalStorage(){
    ImageView imageView = (ImageView) findViewById(R.id.image);
    ContextWrapper cw = new ContextWrapper(context);

    //path to /data/data/yourapp/app_data/dirName
    File directory = cw.getDir("dirName", Context.MODE_PRIVATE);          
    File mypath=new File(directory,"imagename.jpg");

    ImageView imageView = (ImageView) findViewById(R.id.image);
    imageView.setImageDrawable(Drawable.createFromPath(mypath.toString()));
}

代码未经测试.或尝试以下！

Code isn't tested. Or Try Below!

private void setImage(String imgPath)
{

    try {
        File f=new File(imgPath, "imgName.jpg");
        Bitmap b = BitmapFactory.decodeStream(new FileInputStream(f));
        ImageView img=(ImageView)findViewById(R.id.image);
        img.setImageBitmap(b);
    } 
    catch (FileNotFoundException e) 
    {
        e.printStackTrace();
    }

}
