Load an image from assets folder

Question

I am trying to load an image from the asset folder and then set it to an ImageView. I know it\'s much better if I use the R.id.* for t

Answer 1

public static Bitmap getImageFromAssetsFile(Context mContext, String fileName) {
        Bitmap image = null;
        AssetManager am = mContext.getResources().getAssets();
        try {
            InputStream is = am.open(fileName);
            image = BitmapFactory.decodeStream(is);
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return image;
    }

Answer 2

If you know the filename in the code, calling this won't be a problem:

ImageView iw= (ImageView)findViewById(R.id.imageView1);  
int resID = getResources().getIdentifier(drawableName, "drawable",  getPackageName());
iw.setImageResource(resID);

Your filename will be the same name as drawableName so you won't have to deal with assets.

Answer 3

WebView web = (WebView) findViewById(R.id.webView);
web.loadUrl("file:///android_asset/pract_recommend_section1_pic2.png");
web.getSettings().setBuiltInZoomControls(true);

Answer 4

Checkout this code . IN this tutorial you can find how to load image from asset folder.

// load image

try 
{
    // get input stream
    InputStream ims = getAssets().open("avatar.jpg");
    // load image as Drawable
    Drawable d = Drawable.createFromStream(ims, null);
    // set image to ImageView
    mImage.setImageDrawable(d);
  ims .close();
}
catch(IOException ex) 
{
    return;
}

Answer 5

This worked in my use case:

AssetManager assetManager = getAssets();
ImageView imageView = (ImageView) findViewById(R.id.imageView);
try (
        //declaration of inputStream in try-with-resources statement will automatically close inputStream
        // ==> no explicit inputStream.close() in additional block finally {...} necessary
        InputStream inputStream = assetManager.open("products/product001.jpg")
) {
    Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
    imageView.setImageBitmap(bitmap);
} catch (IOException ex) {
    //ignored
}

Some of these answers may answer the question but I never liked any of them so I ended up writing this, it my help the community.

Get Bitmap from assets:

public Bitmap loadBitmapFromAssets(Context context, String path)
{
    InputStream stream = null;
    try
    {
        stream = context.getAssets().open(path);
        return BitmapFactory.decodeStream(stream);
    }
    catch (Exception ignored) {} finally
    {
        try
        {
            if(stream != null)
            {
                stream.close();
            }
        } catch (Exception ignored) {}
    }
    return null;
}

Get Drawable from assets:

public Drawable loadDrawableFromAssets(Context context, String path)
{
    InputStream stream = null;
    try
    {
        stream = context.getAssets().open(path);
        return Drawable.createFromStream(stream, null);
    }
    catch (Exception ignored) {} finally
    {
        try
        {
            if(stream != null)
            {
                stream.close();
            }
        } catch (Exception ignored) {}
    }
    return null;
}
