Create ImageViews dynamically inside a loop

Question

I have written this code that loads an image to in ImageView widget:

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.gallery);
    i = (ImageView)findViewById(R.id.imageView1);

    new get_image("https://www.google.com/images/srpr/logo4w.png") {
        ImageView imageView1 = new ImageView(GalleryActivity.this);

        ProgressDialog dialog = ProgressDialog.show(GalleryActivity.this, "", "Loading. Please wait...", true);

        protected void onPreExecute(){
             super.onPreExecute();
        }

         protected void onPostExecute(Boolean result) {
             i.setImageBitmap(bitmap); 
         dialog.dismiss();
         }
    }.execute();


}

bu now, I want to load several images. for this I need create image views dynamically but i don't know how...

I want run my code inside a for loop:

for(int i;i<range;i++){
   //LOAD SEVERAL IMAGES. READ URL FROM AN ARRAY
}

my main problem is creating several ImageViews inside a loop dynamically

Answer 1

you can modify the layout , image resource and no of images (may be dynamic as well) according to your requirement...

LinearLayout layout = (LinearLayout)findViewById(R.id.imageLayout);
for(int i=0;i<10;i++)
{
    ImageView image = new ImageView(this);
    image.setLayoutParams(new android.view.ViewGroup.LayoutParams(80,60));
    image.setMaxHeight(20);
    image.setMaxWidth(20);

    // Adds the view to the layout
    layout.addView(image);
}

Answer 2

You can use this code to create ImageViews

ImageView image = new ImageView(this);
LinearLayout.LayoutParams vp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
image.setLayoutParams(vp);
image.setMaxHeight(50);
image.setMaxWidth(50);
// other image settings
image.setImageDrawable(drawable);
theLayout.addView(image);

where theLayout is the layout you want to add your image views to.

For more customization check out the dev page, where all the possible options are listed.

If your requirement is show in List or Gridview then you should go for Lazy Loading List or grid.

Try this

 rootLayout = (LinearLayout) view1.findViewById(R.id.linearLayout1);

    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    params.gravity = Gravity.CENTER_VERTICAL;

    params.setMargins(0, 0, 60, 0);


    for(int x=0;x<2;x++) {
        ImageView image = new ImageView(getActivity());

        image.setBackgroundResource(R.drawable.ic_swimming);
        rootLayout.addView(image);
    }
