Try to add or override setOnTouchListener for GridView, then in onTouch method you can use code like this to make gridview not scrolling :

gridview.setOnTouchListener(new OnTouchListener(){

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_MOVE){
            return true;
        }
        return false;
    }

});


Use this custom gridview. It automatically sets the height and does not scroll:

public class MyGridView extends GridView {
    public MyGridView(Context context) {
        super(context);
    }

    public MyGridView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyGridView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int heightSpec;

        if (getLayoutParams().height == LayoutParams.WRAP_CONTENT) {
            // The great Android "hackatlon", the love, the magic.
            // The two leftmost bits in the height measure spec have
            // a special meaning, hence we can't use them to describe height.
            heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        } else {
            heightSpec = heightMeasureSpec;
        }

        super.onMeasure(widthMeasureSpec, heightSpec);
    }
}


GridView is designed to scroll vertically, and I am not aware that you can stop it from scrolling. If you do not want scrolling, do not use a GridView.


public class myGridView extends GridView {

    public myGridView(Context context) {
        super(context);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {

    switch(event.getAction()){

    case MotionEvent.ACTION_DOWN:
    return super.onTouchEvent(event);

    case MotionEvent.ACTION_MOVE:
    //Do nothing here!!!
    break;

    case MotionEvent.ACTION_UP:
    return super.onTouchEvent(event);
    }

    //false return 
    return false;
    }
}
