How to disable a grid item when loading activity

I have few grid elements. Depending on the flag, I want to disable some grid elements.

For instance:

  • Grid elements are Order, CallLost, Payment. If boolean status = true, then I want to disable CallLost . Others should be included.
    • If boolean status = false, then I want to disable Order , Payment and CallLost

& I made grid elements using:

  @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.retailer_main); Bundle bundle = this.getIntent().getExtras(); retailerName = bundle.getString("RetailerName"); relailerCode = bundle.getString("RetailerCode"); isDefault = bundle.getBoolean("isDefault", false); routeCode = bundle.getString("RouteCode"); getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); SharedPreferences myRoutes = this.getSharedPreferences("myDefalutRoute",MODE_PRIVATE); defaultRoutePositions = myRoutes.getInt("defaultRoutePositions", -1); retailerGrid = (GridView)findViewById(R.id.retailergridview); retailerGrid.setAdapter(new RetailerImageAdapter(this)); retailerGrid.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View v, int position,long id) { if (position == 0) { Intent i = new Intent(getBaseContext(), RetailerOrderActivity.class); Bundle bundle = new Bundle(); bundle.putString("Activity", "RetailerOptionActivity"); bundle.putString("RetailerName", retailerName); bundle.putString("RetailerCode", relailerCode); i.putExtras(bundle); View vi = SalesActivityGroup.group.getLocalActivityManager().startActivity("RetailerOrderActivity", i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); SalesActivityGroup.group.replaceView(vi); } if (position == 2) { Intent i = new Intent(getBaseContext(), CallLostActivity.class); Bundle bundle = new Bundle(); bundle.putString("Activity", "RetailerOptionActivity"); bundle.putString("RetailerName", retailerName); bundle.putString("RetailerCode", relailerCode); i.putExtras(bundle); View vi = SalesActivityGroup.group.getLocalActivityManager().startActivity("RetailerOrderActivity", i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); SalesActivityGroup.group.replaceView(vi); } } }); Button reOpCancel = (Button)findViewById(R.id.reOpCancel); reOpCancel.setOnClickListener(new OnClickListener() { public void onClick(View v) { Intent i = new Intent(getBaseContext(), ListRetailerActivity.class); Bundle bundle = new Bundle(); bundle.putString("RetailerName", retailerName); bundle.putString("RetailerCode", relailerCode); bundle.putInt("positon", defaultRoutePositions); bundle.putString("RouteCode", routeCode); i.putExtras(bundle); View vi = SalesActivityGroup.group.getLocalActivityManager().startActivity("ListRetailerActivity", i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); SalesActivityGroup.group.replaceView(vi); isDefault = false; //defaultRoutePositions = -1; } }); } public void onCancelAction(View view){ SalesActivityGroup.group.back(); return; } public void onCompleteAction(View view){ SalesActivityGroup.group.back(); return; } public class RetailerImageAdapter extends BaseAdapter{ Context MyContext; public RetailerImageAdapter(Context _MyContext){ MyContext = _MyContext; } public int getCount() { return mThumbIds.length; } public View getView(int position, View convertView, ViewGroup parent) { View v; if(convertView==null){ LayoutInflater li = getLayoutInflater(); v = li.inflate(R.layout.grid_item, null); TextView tv = (TextView)v.findViewById(R.id.grid_item_text); tv.setText("Profile "+position); ImageView iv = (ImageView)v.findViewById(R.id.grid_item_image); tv.setText(names[position]); iv.setImageResource(mThumbIds[position]); } else { v = convertView; } return v; } public Object getItem(int arg0) { return null; } // public boolean areAllItemsEnabled() { // return false; // } // // // public boolean isEnabled(int position) { // if(isDefault){ // if(position == 0) return true; // if(position == 1) return true; // if(position == 3) return true; // // }else{ // if(position == 2) return false; // } // return false; // } public long getItemId(int arg0) { return 0; } // references to our images private Integer[] mThumbIds = { R.drawable.one, R.drawable.two, R.drawable.five, R.drawable.four, R.drawable.eight,R.drawable.seven, R.drawable.seven,R.drawable.seven, R.drawable.seven }; private String[] names = { "Order","Order Flow", "Call Lost","Collection", "Cancel Invoice","Survey", "Complain","Customer Card", "ComInv" }; } }

Please comment on this. I saw this one , but it disables all elements, only specific ones.

I assume that when you say “disconnect”, you intend to make the grid element un-clickable (but still visible) - as in View.setEnabled() .

Try this in RetailerImageAdapter.getView() , before return ;

 if (isDefault && position == 2) { v.setEnabled(false); } else if (!default) { if (position == 0 | position == 1 | position == 3) { v.setEnabled(false); } }

I'm not sure if this will work (I have not tested it), but theoretically it should be.

enter the code below before the return view in the getView () method in the RetailerImageAdapter class

 if(isDefault){ v.setClickable(true); } else{ v.setClickable(false); } return v;

Note: check the opposite, depending on your condition.
