    <p>I have tried all my best to look for solution everywhere including SO but it seems that I am not getting anywhere and I decided to ask the question to see if I can get someone that will help me out on this. OK here is what I am trying to do:</p> <p>I have a GridView of 4 columns and 4 rows. The GridView is filled with images using imageAdapter. When an image is selected in a row the image in that position changes to another image and when it is selected (Deselected) again it changes back to the previous image. That is fine. what I am trying to do now is that when a position is selected, I want to disable all other position until the selected position is deselected by clicking on it again. In essence I want to make sure that no two positions can be selected at the same time. I have tried my best but this seems a bit impossible for now. Can anyone please tell me what I am doing wrong. When the user select a position, in a row others don't get disabled. Below is my code: Any help will be much appreciated. Thank you for your anticipated help.</p> <p>private OnItemClickListener onGridItemClickListener = new OnItemClickListener() {</p> <pre><code> public void onItemClick(AdapterView&lt;?&gt; parent, View v, int position, long id) { //if (v == null) return; //Just added 03/04/2013 int rowOfSelectedItem = getRowInGrid(position); Log.i(TAG, "Selected View is : "+v.getId()+" (Id arg = "+id+")- Position is "+ position+" Row is = "+rowOfSelectedItem); switch(rowOfSelectedItem){ case 1: //iterate through first row items and check if any of the items was selected before for(int x=2; x &lt; 4; x++){ // Object tag = ((ImageView)gridView.getChildAt(x)).getTag(); Log.i(TAG, "This is : "+ x + "TAG is " + tag); if(tag ==null || !Boolean.valueOf(tag.toString())){ //disable clicking so the user cannot select another image on same row ((ImageView)gridView.getChildAt(x)).setClickable(false); ((ImageView)gridView.getChildAt(x)).setEnabled(false); Log.i(TAG, "This is : "+ x + tag); } } break; case 2: for(int x=4; x &lt; 8; x++){ // Object tag = ((ImageView)gridView.getChildAt(x)).getTag(); if(tag ==null || !Boolean.valueOf(tag.toString())){ //disable clicking so the user cannot select another image on same row ((ImageView)gridView.getChildAt(x)).setClickable(false); ((ImageView)gridView.getChildAt(x)).setEnabled(false); } } break; case 3: for(int x=8; x &lt; 12; x++){ // Object tag = ((ImageView)gridView.getChildAt(x)).getTag(); if(tag ==null || !Boolean.valueOf(tag.toString())){ //disable clicking so the user cannot select another image on same row ((ImageView)gridView.getChildAt(x)).setClickable(false); ((ImageView)gridView.getChildAt(x)).setEnabled(false); } } break; case 4: for(int x=12; x &lt; 16; x++){ // Object tag = ((ImageView)gridView.getChildAt(x)).getTag(); if(tag ==null || !Boolean.valueOf(tag.toString())){ //disable clicking so the user cannot select another image on same row ((ImageView)gridView.getChildAt(x)).setClickable(false); ((ImageView)gridView.getChildAt(x)).setEnabled(false); } } break; } </code></pre> <p>private int getRowInGrid(int position){</p> <pre><code> if(position &lt;= 3){ return 1; } else if(position &lt;=7){ return 2; } else if(position &lt;= 11){ return 3; } else if(position &lt;= 15){ return 4; } else{ return -1;} } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
