How to set some item unclickable in GridView

For example, I need to judge the contents of the item in the Item can be clicked.
enter image description here
As shown in the picture, I need to get the gray Item cannot be clicked.
Here is my adapter
public class RoomAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private Context mContext;
private List<Room> mDatas;
public RoomAdapter(Context context, List<Room> mDatas) {
mInflater = LayoutInflater.from(context);
this.mContext = context;
this.mDatas = mDatas;
}
#Override
public int getCount() {
return mDatas.size();
}
#Override
public Object getItem(int position) {
return mDatas.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Room room = mDatas.get(position);
ViewHolder viewHolder = null;
View view;
if (convertView == null) {
viewHolder = new ViewHolder();
view = mInflater.inflate(R.layout.roomstate_item, null);

}else{

}
// String nu = room.getRoom_number();
viewHolder.tv_roomstate.setText(room.getRoom_status());

I set view.setClickable (false)in my Adapter, but it does not work.

item.setEnabled(false);
when u need to make it clickable call
item.setEnabled(true);
Here item is your edittext or button or anything else
Try this:
if (room.getRoom_status().equals("0") &&room.getRoomType().getRoom_type_name().equals("0")) {
view.setBackgroundResource(R.drawable.single);
view.setEnabled(false);
} else if (room.getRoom_status().equals("1") && room.getRoomType().getRoom_type_name().equals("0")) {
view.setBackgroundResource(R.drawable.single_b);
} else if (room.getRoom_status().equals("1") && room.getRoomType().getRoom_type_name().equals("1")) {
view.setBackgroundResource(R.drawable.double_b);
} else if(room.getRoom_status().equals("0") && room.getRoomType().getRoom_type_name().equals("1")){
view.setEnabled(false);
view.setBackgroundResource(R.drawable.doubleg);
}
else
view.setEnabled(true);

The right way is to write a Boolean value, and let it based on a Boolean value to determine whether to jump.
private boolean checkedIntent = false;
if (roomstate.equals("0") && roomtype.equals("0")) {
checkedIntent = false;
} else if (roomstate.equals("1") && roomtype.equals("0")) {
checkedIntent = true;
} else if (roomstate.equals("1") && roomtype.equals("1")) {
checkedIntent = true;
} else if (roomstate.equals("0") && roomtype.equals("1")) {
checkedIntent = false;
}
if (checkedIntent == true) {
Intent intent = new Intent(RoomList.this, BookRoomDetail.class);
intent.putExtras(mBundle);
startActivity(intent);
}

The application's PagerAdapter changed the adapter's contents

I'm trying to build a pager to display images, sequentially. But I am getting this error.
The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged!
Expected adapter item count: 0, found: 1 Pager id:.
Please someone guide to fix it.

this is what is causing the crash you can't add multiple objects to an array that is attached to an adapter inside a for loop
move this
mAdapterForGellary = new MyViewPagerAdapter(imageList);
//imageExtendedGallery.setAdapter(mAdapterForGellary);
viewPager.setAdapter(mAdapterForGellary);
to on post execute of the task

add this to your pager adapter
// Trying to add data dynamically
public void addData(#NonNull List<Object> data) {
mData.addAll(data);
notifyDataSetChanged();
}
after that in your main method
MyAdapter myAdapter = new MyAdapter(getContext());
myViewPager.setAdapter(myAdapter);
myViewPager.setScrollMode(UltraViewPager.ScrollMode.HORIZONTAL);
myViewPager.setPageTransformer(false, new UltraDepthScaleTransformer());
// Runs after data loaded from server (in the future):
myAdapter.addData(myData)
i hope this helps.

How to update the value of the textview inside the fragment on the click of the button present in the adapter class in android?

In your Adapter class create one interface
Adapter.class
public class CartBaseAdapter extends BaseAdapter {
private Context mContext;
private ArrayList<PojoCart> mList;
private ViewHolder viewHolder;
private HashMap<String, Integer> mHashMap = new HashMap<String, Integer>();
private Integer total;
private DataBaseHandler dbh;
private int Id = 1;
private String value1, value2;
private int z;
private FragmentTransactionListener fragmentTransactionListener = (FragmentTransactionListener) new Cart();
private SendDataToFragment sendDataToFragment;
public CartBaseAdapter(FragmentCart fragmentCart, Context mContext, ArrayList<PojoCart> mList) {
this.mContext = mContext;
this.mList = mList;
dbh = new DataBaseHandler(mContext);
sendDataToFragment = (SendDataToFragment) fragmentCart;
}
//Interface to send data from adapter to fragment
public interface SendDataToFragment {
void sendData(String Data);
}
#Override
public int getCount() {
return mList.size();
}
#Override
public Object getItem(int position) {
return mList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.cart_item, parent, false);
viewHolder = new ViewHolder();
viewHolder.mImgItem = (ImageView) convertView.findViewById(R.id.cart_image);
viewHolder.mTvItemName = (TextView) convertView.findViewById(R.id.tv_item_name);
viewHolder.mTvItemPrice = (TextView) convertView.findViewById(R.id.tv_item_price);
viewHolder.mTvNumber = (TextView) convertView.findViewById(R.id.tv_number);
viewHolder.mBtnAdd = (Button) convertView.findViewById(R.id.btn_add);
viewHolder.mBtnMinus = (Button) convertView.findViewById(R.id.btn_sub);
viewHolder.mImgDelete = (ImageView) convertView.findViewById(R.id.img_del);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
convertView.setTag(viewHolder);
final PojoCart pojoCart = (PojoCart) getItem(position);
viewHolder.mTvItemName.setText(pojoCart.getmItemName());
viewHolder.mTvItemPrice.setText(pojoCart.getmItemPrice());
viewHolder.mImgItem.setImageBitmap(Utility.StringToBitMap(pojoCart.getmItemImage()));
viewHolder.mBtnAdd.setTag(pojoCart);
viewHolder.mBtnMinus.setTag(pojoCart);
viewHolder.mTvItemPrice.setTag(pojoCart);
viewHolder.mTvNumber.setTag(pojoCart);
viewHolder.mImgDelete.setTag(position);
if (pojoCart.getmQuantity() > 0) {
viewHolder.mTvNumber.setText("" + pojoCart.getmQuantity());
} else {
viewHolder.mTvNumber.setText("" + 0);
}
viewHolder.mBtnAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Send data via interface to your fragment
sendDataToFragment.sendData("Your Data");
//Your existing code
}
});
viewHolder.mBtnMinus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Send data via interface to your fragment
sendDataToFragment.sendData("Your Data");
//Your existing code
}
});
return convertView;
}
private class ViewHolder {
TextView mTvItemName, mTvItemPrice, mTvNumber;
ImageView mImgItem, mImgDelete;
Button mBtnAdd, mBtnMinus;
}
}
Inside your fragment implement that interface so as soon as your button is clicked in your adapter you will get the data inside your fragment.
Fragment.class
public class FragmentCart extends Fragment implements
View.OnClickListener, CartBaseAdapter.SendDataToFragment{
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.your_layout, null);
return rootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
CartBaseAdapter adapter = new CartBaseAdapter(FragmentCart.this, getActivity(), yourList);
}
#Override
public void onClick(View v) {
}
#Override
public void sendData(String Data) {
//set this data to your textView
}
}

Create a interface :
public interface MyListener {
// you can define any parameter as per your requirement
public void callback(View view, int value);
}
In your listview adapter use interface like below on click of button + or - like :
MyListener ml;
ml = (MyListener) context;
ml.callback(this, "success");
In activity implements MyListener than callback method override there and than you get performed action from fragment to activity.

How to refresh fragment from out of activity or fragment but from baseAdapter class

I have some problem. when I click a delete(btnPlus.setOnClickListener in the interestAdepter class) button from listview baseAdapter, I want to refresh the fragment which contains the listview.

Update your adapter constructor. After deleting content, remove the item from the arraylist and notify dataset changed.

Update Adapter initialization in fragment. You are adding item to adapter directly. Use arraylist and after downloading data create adapter instance.
private ArrayList<InterestClass> interestList = new ArrayList<>();
and update your onPostExecute Method
#Override
protected void onPostExecute(JSONArray result) {
try{
for (int i = 0 ; i < result.length() ; i ++){
InterestClass i_Class = new InterestClass();
String date=result.getJSONObject(i).getString("indate");
String time=date.substring(5,date.length());
i_Class.setJmcode(result.getJSONObject(i).getString("jmcode"));
i_Class.setName(result.getJSONObject(i).getString("jmname"));
i_Class.setDate(time);
i_Class.setConPrice(result.getJSONObject(i).getString("fprice"));
i_Class.setNowPrice(result.getJSONObject(i).getString("price"));
i_Class.setFog("40");
i_Class.setPlus(true);
interestList.add(i_Class);
}
interest_Adapter = new InterestAdapter(getActivity,interestList);
interest_ListView.setAdapter(interest_Adapter);
}catch(Exception e){
Toast.makeText(getActivity(), "interest"+e.getMessage(), Toast.LENGTH_SHORT).show();
}
}

If I understand you correctly you want to remove the item from your ListView too after your removing it from your Database, to achieve that you can call this
m_List.remove(position);
interest_Adapter..notifyDataSetChanged();
First line removes the item and Second one will insure that the Adapter gets updated after the item has been removed.
Hope this helps

Why a fragment is not executing?

I am trying to call a new fragment in android and when I am clicking the button Search it is working but after to execute the code:
Activity ac = (Activity) v.getContext();
AllFragment to = new AllFragment(null, false);
FragmentTransaction fragTransaction = ac.getFragmentManager().beginTransaction();
fragTransaction.replace(R.id.frame_container, to);
fragTransaction.addToBackStack(null);
fragTransaction.commit();
after it I see in the emulator the next screen:
then what I expected is a Listview of Products. The code I have in the fragment it is working perfect.
my fragment code is:
#SuppressLint("UseValueOf")
public class AllFragment extends ListFragment {
String codigo = null;
boolean esOferta = false;
public AllFragment(String codigo, boolean esOferta) {
this.esOferta = esOferta;
this.codigo = codigo;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
try
{
DataBaseManager db = new DataBaseManager(inflater.getContext());
Integer poblacion = null;
Integer provincia = null;
String codigo = null;
ArrayList<ProductsOffers> data = null;
if (db.existKey("PROVINCIA")) provincia = new Integer(db.getDatoByKey("PROVINCIA"));
if (db.existKey("POBLACION")) poblacion = new Integer(db.getDatoByKey("POBLACION"));
if (db.existKey("CODIGO")) codigo = db.getDatoByKey("CODIGO");
if (!this.esOferta) data = IAndroid.getAllProductsAndOffers(provincia, poblacion, this.codigo, null, null);
else {
data = IAndroid.getProductsByOfferCode(this.codigo);
}
if (data != null) setListAdapter(new ProductOffersListAdapter(inflater.getContext(), data));
}
catch (Exception ex)
{
}
return super.onCreateView(inflater, container, savedInstanceState);
}
#Override
public void onDestroyView() {
super.onDestroyView();
}
}
In my emulator I am using version 4.0.3
My adapter code is:
public class ProductOffersListAdapter extends BaseAdapter {
private Context context;
private ArrayList<info.android.model.ProductsOffers> navProOffers;
public ProductOffersListAdapter(Context context, ArrayList<info.android.model.ProductsOffers> navProOffers) {
this.context = context;
this.navProOffers = navProOffers;
}
#Override
public int getCount() {
return navProOffers.size();
}
#Override
public info.android.model.ProductsOffers getItem(int position) {
return navProOffers.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.fragment_row, null);
}
ProductsOffers po = (ProductsOffers) getItem(position);
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
TextView vwtipo = (TextView) v.findViewById(R.id.vwTipo);
TextView vwcodigo = (TextView) v.findViewById(R.id.txtCodigo);
Activity act = (Activity) v.getContext();
ProductFragment to = new ProductFragment(vwcodigo.getText().toString(), vwtipo.getText().equals("OFERTA"));
FragmentTransaction fragTransaction = act.getFragmentManager().beginTransaction();
fragTransaction.replace(R.id.frame_container, to);
fragTransaction.addToBackStack(null);
fragTransaction.commit();
}
});
try
{
ImageView img = (ImageView) convertView.findViewById(R.id.image);
TextView vwtipo = (TextView) convertView.findViewById(R.id.vwTipo);
TextView txtCodigo = (TextView) convertView.findViewById(R.id.txtCodigo);
TextView txtCiudad = (TextView) convertView.findViewById(R.id.txtCiudad);
TextView txtVF = (TextView) convertView.findViewById(R.id.txtVF);
String sVF = Double.toString(getItem(position).ValorFinal) + "€";
String aux = "";
aux = po.tipo;
vwtipo.setText((aux.equals("O"))? "OFERTA":"PRODUCTO");
vwtipo.setBackgroundColor(aux.equals("O")?Color.RED: Color.WHITE);
txtVF.setText(sVF);
txtCiudad.setText(po.ciudad);
txtCodigo.setText(po.codigo);
convertView.setTag(po.codigo);
img.setImageBitmap(po.Imagen);
} catch (Exception ex) {}
return convertView;
}
}
