How to set data in a Gridview dyanamically

[NeelNisha Singh]

I have created a gridview and added adapter to show view dyanamically

Here is my code

1.GroupIDUDesAct .java

public class GroupIDUDesAct extends Activity {
	
	GridView gridIDU;
	String[] iduName={"A","B","C","D","E"};
	String[] setTemp={"10","20","24","25","12"};
	String[] tempValue={"18","18","18","18","18"};
	int[] imageID={R.drawable.casset_ac,R.drawable.concealled_ac};
	String[] iduActive_deactiveStatus={"1","0","1","0","1"};
	
	@SuppressLint("NewApi")
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		
		setContentView(R.layout.group_idu_des);
		
		final ActionBar actionBar = getActionBar();

        // Specify that the Home button should show an "Up" caret, indicating that touching the
        // button will take the user one step up in the application's hierarchy.
        actionBar.setDisplayHomeAsUpEnabled(true);
		
		initialize();
	}

	private void initialize() {
		gridIDU=(GridView) findViewById(R.id.gridViewId);
		
		gridIDU.setAdapter(new MyArrayAdapter(this,iduName, setTemp,tempValue,imageID,iduActive_deactiveStatus));
	}
	
	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) {
	    // Respond to the action bar's Up/Home button
	    case android.R.id.home:
	        Intent upIntent = NavUtils.getParentActivityIntent(this);
	        if (NavUtils.shouldUpRecreateTask(this, upIntent)) {
	            // This activity is NOT part of this app's task, so create a new task
	            // when navigating up, with a synthesized back stack.
	            TaskStackBuilder.create(this)
	                    // Add all of this activity's parents to the back stack
	                    .addNextIntentWithParentStack(upIntent)
	                    // Navigate up to the closest parent
	                    .startActivities();
	        } else {
	            // This activity is part of this app's task, so simply
	            // navigate up to the logical parent activity.
	            NavUtils.navigateUpTo(this, upIntent);
	        }
	        return true;
	    }
	    return super.onOptionsItemSelected(item);
	}
	
	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		// TODO Auto-generated method stub
		super.onActivityResult(requestCode, resultCode, data);
	}
	
	public class MyArrayAdapter extends BaseAdapter{

So what part are you having trouble with? The layout or the gridview or what?

Your row_deactive.xml is not that great. When using GridView (and probably ListView as well) you should try to avoid nesting layouts. You have a RelativeLayout with a LinearLayout inside. You do not need, and should not use the LinearLayout at all. You should just use the RelativeLayout. For reference see: http://developer.android.com/guide/topics/ui/layout/relative.html
