How To Set Imageview Using Bitmap Array

I'm doing one demo of getting Image URLs through JSON and after getting the ULR I'm downloading that images and display them into the GridView. For storing downloaded images I'm us

Solution 1:

Its so simple way use setImageBitmap..

imageView.setImageBitmap(imageAdapter.bm[position]);

Solution 2:

You should use , setImageBitmap (Bitmap bm) method which Sets a Bitmap as the content of this ImageView.

So your code will be,

imageView.setImageBitmap(imageAdapter.bm[position]);

Docs.

Solution 3:

imageView.setImageBitmap(imageAdapter.bm[position]);

Solution 4:

here i give you my code of my app that works with a gallery from drawable resources with int position, modify it for your needs, should work with your code.

My intent of gallery is:

@OverridepublicvoidonItemClick(AdapterView<?> parent, View  view, int position, long id) {
    intselectedId= imgs[position]; 
    Intentintent=newIntent(Gallery3DActivity.this,MainActivity.class);
    intent.putExtra("imageId", selectedId);
    startActivity(intent);
}

In the main activity i receive the intent and set it on the imageview:

Intentavatar= getIntent(); 
intimageId= avatar.getIntExtra("imageId", -0); 
// -0 would be a default value// -1 will crash with a missing resourceif (getIntent().getExtras() != null) {
    Avatar.setImageResource(imageId);
    savedAvatar.setImageResource(imageId);
} else {
    Avatar.setImageResource(R.mipmap.ic_launcher);
}

Your code is similiar as mine, but you get it from url them to bitmap, me i get it from drawable resources, with long id list set on the activity java for name and position, i chose the one i want to set as avatar them pass it inside intent to main activity and define the intent name that contains the drawable cache to an imageview, after in button onclick i convert to bitmap, bitmap to string, string to image to restore imageview view on start main activity, and i save the string to sharedpreferences, getting the imageview view back again even after close the app.

Good luck
