Question

What I tried

---

Hello Guys, I have made a GridView which I’ve filled over my database. Now I made an onItemClickListner, from the Google GridView tutorial. Now I tried to make that when the user clicks on a picture in the GridView, it keeps selected and gets a backgroundcolor so the user sees which Image he chooses.
But exactly this isn’t working how it should. I made a If with a boolean which allways when the User clicks on the next View, that the old View gets transperent again and the new clicked View got a backgroundcolor. But after I selected a View and I scroll up and down. The highlighted View changes sometimes randomstyled.

Question

So my question is what I have to change in my onItemClickListner, that this random View changing stops (?), I didn’t found out a way to do so. And is there a easier way to highlight the selected View?
For the understanding “selected View” = User clicks on it, than its selected and should be highlighted.

Here’s the Code of my onItemClickListner:

    //Hier wird die Grindview gefüllt
    final GridView gridview = (GridView) findViewById(R.id.SmileyGrind);
    gridview.setAdapter(new ImageAdapter(this, info));


    //Hier wird gemerkt welches bild
    gridview.setOnItemClickListener(new OnItemClickListener() {

boolean color = false;
View vv;


        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            Toast.makeText(SFilterConfigActivity.this, "" + position, Toast.LENGTH_SHORT).show();
           // gridview.setSelection(position);

            if ( color == false){
                v.setBackgroundColor(0xFF00FF00);
                vv = v;
                color = true;

            }
            else {
                vv.setBackgroundColor(0x00000000);
                v.setBackgroundColor(0xFF00FF00);
                vv = v;


            }


        }      
    });

Answer 1

I had the same issue but it was with ListView .follow this it will work for GridView too.

if(position == grid.getSelectedItemPosition())
   holder._linear.setBackgroundColor(Color.GRAY);           
else  
   holder._linear.setBackgroundColor(Color.BLACK);

and get the Parent Layout of the Layout that you are using for your GridView and on onClick method of layout just add this .

 holder._linear.setBackgroundColor(Color.GRAY); 

This will change the Background color of the layout and the above code will solve your random background problem.
