Question

When I run my app on screen 4.3 it works fine but when I run on 3.14 screen, images don’t show correctly one above the other in a big size.

Is there a way to show an image using percentage which depends on different screen sizes?

Here is the ImageView code:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView = new ImageView(mContext);
    imageView.setImageResource(mThumbIds[position]);
    imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
    imageView.setLayoutParams(new GridView.LayoutParams(200,200 ));
    return imageView;
}

i found the solution of my answer
it’s close to @dmon answer

I created dimensions.xml in Values folder

<?xml version="1.0" encoding="utf-8"?>
<resources>
<dimen name="width">150dp</dimen>   
<dimen name="height">150dp</dimen>
</resources>

and in imageadapter.java

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView = new ImageView(mContext);
    imageView.setImageResource(mThumbIds[position]);
    imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
    imageView.setLayoutParams(new GridView.LayoutParams(
            (int) mContext.getResources().getDimension(R.dimen.width),                                                                                   
            (int) mContext.getResources().getDimension(R.dimen.height)));
    imageView.setPadding(5, 5, 5, 5);
    return imageView;
}
