add these lines to your code.

LinearLayout linearLayout = findViewById(R.id.linear);
1-create an instance of ImageView
ImageView image = new ImageView(this);
//find resource from uril
int imageResource = 
getResources().getIdentifier(fileUri,null,getPackageName());
Drawable res = getResources().getDrawable(imageResource);
image.setImageDrawable(res);
//this will add the imageto the layout.
linearLayout.addView(image);
