Answer 1

First you need to create an imageview.

ImageView imageView = new ImageView(getApplicationContext());

Create layout param to add imageview on layout

LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

Then get your image path

String path = Environment.getExternalStorageDirectory() + "/your folder name/image_name.bmp";

Set your image on ImageView

Bitmap image = BitmapFactory.decodeFile(path);
imageView.setImageBitmap(image);

Fetch your layout on which you want to add

RelativeLayout rl = (RelativeLayout) findViewById(R.id.relativeLayout1);

Add your view to the layout

rl.addView(imageView, lp);
