You can take the images in your resource folder. After that follow this simple code:
try {
Class<drawable> res = R.drawable.class;
if(str!=null){
Field field = res.getField(str);
int drawableId = field.getInt(null);
bengalidaypng.setImageResource(drawableId);
}
}
catch (Exception e) {
System.out.println("Image not found in drawable folder");
}

您可以使用 类型化数组 资源。链接末尾有一个示例，说明如何将其用于可绘制对象（图像）。
编辑：
资源可以作为原始数据访问：使用AssetManager.open(..)
然后你可以使用 BitmapFactory.decodeStream(. .) 从数据流创建位图。
You could use Typed Array resource. There is an example at the end of the link how to use it for drawables (images).
Edited:
Resources can be accessed as raw data: use AssetManager.open(..)
Then you can use BitmapFactory.decodeStream(..) to create a Bitmap from the data stream.
您可以在资源文件夹中获取图像。之后遵循这个简单的代码：

您可以将图像存储到数据库中，然后 当您绑定每一行时，将图像拉入 ListView。
You could store the images into a database, then pull the images into the ListView when you are binding each row.
