How can I put drawable image into gridview?

How can I put drawable image into gridview? - java

I have a gridview with 5 columns, how could add in column 4 and 5, images that I have in drawable folder? The problem is that being a String arraylist not catch me drawable because it is an integer.
This is my XML:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/scrolView"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:orientation="vertical">
<GridView
android:id="#+id/Grid"
android:numColumns="5"
android:stretchMode="columnWidth"
android:layout_width="match_parent"
android:gravity="center"
android:columnWidth="120dp"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:layout_height="2000dp"
android:layout_marginTop="10dp"
android:layout_marginLeft="30dp"></GridView>
</LinearLayout>
This is the java code where I call carrito.xml, and i make the listview. This list view is filled with a String array.
public class carrito extends Fragment {
protected Context context;
private int numComandesCarrito;
private String[][] CarritoProductes;
private double Total;
DecimalFormat precision = new DecimalFormat("0.00");
NumberFormat formatter = NumberFormat.getCurrencyInstance();
String output = formatter.format(Total);
public carrito(){
}
public void setContext (Context context){
this.context = context;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
int i, i2;
numComandesCarrito = ((MainActivity) context).getNumComandesCarrito();
// Toast.makeText(context, Integer.toString(numComandesCarrito), Toast.LENGTH_LONG).show();
CarritoProductes = ((MainActivity) context).getCarritoProductes();
Total = 0;
ArrayList<String> lineasPedido = new ArrayList<String>();
ArrayList<Integer> itemsimg = new ArrayList( );
//Afegim la capçalera de la grid
lineasPedido.add("Plat");
lineasPedido.add("Quantitat");
lineasPedido.add("Preu");
for (i= 0; i < numComandesCarrito; i++){
for (i2 = 0; i2<3; i2++){
if (i2 == 2) {
lineasPedido.add(precision.format(Double.parseDouble(CarritoProductes[i2][i])) + " €");
Total = Total + Double.parseDouble(CarritoProductes[i2][i]);
}
else{
lineasPedido.add(CarritoProductes[i2][i]);
}
}
itemsimg.add(R.drawable.botonmenos);
}
lineasPedido.add("");
lineasPedido.add("");
lineasPedido.add("Total: " + (precision.format(Total)) + " €");
View rootView = inflater.inflate(R.layout.carrito, container, false);
GridView grdView = (GridView)rootView.findViewById(R.id.grdComanda);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1, lineasPedido);
grdView.setAdapter(adapter);
return rootView;
}

You have to use custom adapter to put image in gridview

Hope this will work..

Maybe try something like this? The user comments seem to be positive for the most part. http://www.compiletimeerror.com/2013/02/display-images-in-gridview.html#.VRF2I2NTf5w

Why is recycler giving a strange behaviour with selection?

I have made an Image Editor and it works fine. Now, in my recent edits page, I added a feature select multiple items. But, I get a strange behaviour when I refresh the recycler view. See this ->
https://www.veed.io/view/43fa65a4-24e6-44e8-8cea-468ca8c62d7a.
This is my adapter code ->
public class RecentsAdapter extends RecyclerView.Adapter<RecentsAdapter.ViewHolder>{
private List<ImageFile> files;
private final PopupListener popupListener;
RecentItemListeners recentItemListeners;
public Integer selectedItemsCount = 0;
TextView neEditsTV;

this.files = files;
this.popupListener = popupListener;
this.recentItemListeners = listeners;
this.neEditsTV = neEditsTV;
}
public void updateList(List<ImageFile> filesList){
if (files.size() < filesList.size()){
int dif = filesList.size() - files.size();
this.files = filesList;
for (int i = 0; i < dif; i++) {
notifyItemInserted(i);
}
}else if (files.size() > filesList.size()){
for (int i = 0; i < filesList.size(); i++) {
notifyItemChanged(i);
}
notifyDataSetChanged();
notify();
}else {
this.files = filesList;
for (int i = 0; i < filesList.size(); i++) {

Add objects to JSONObj

I want to add objects inside to JSONObj when onClick and display in another Activity inside of a ListView as a CardView.
I tried something but nothing appears, no errors and I have no clue what's the problem.
Here is my code for JSONObj:

jsonData = new JSONObject();
dateJSON = new JSONArray();
obj = new JSONObject();
arrayForList = new JSONArray();
JSONObject objListaSiModalitate = new JSONObject();
// arrayForList.put(stock_list.toString());
objListaSiModalitate.put("lista", new JSONArray(Util.getInstance().getVanzatorProduse()));
objListaSiModalitate.put("metodaPlata", metodaPlata);
obj.put("data", getDate(calendarData.getTimeInMillis()));
obj.put("numeVanzator", numeVanzator);
obj.put("numarClient", 0);
obj.put("detaliiCos", objListaSiModalitate);
dateJSON.put(obj);
jsonData.put("jsonData", dateJSON.toString());
SharedPreference.putString(this, SharedPreference.APP_DATA, SharedPreference.JSON_DATA, jsonData.toString());
} else {

obj.put("produseSelectate", listaProdusePreview.getAdapter().getCount());
int totalPrice = 0;
for (VanzatorProduse v : Util.getInstance().getVanzatorProduse()) {

Hope you understand my question..

The standard way to send data from Activity to another is to pass parcelable data in the Intent bundle.
Make card implement Parcelable
Pass the items to the intent
public void startSecondActivity(List<Card> cards) {
Intent i = new Intent(this, SecondActivity.class);
i.putParcelableArrayListExtra("EXTRA_CARDS", new ArrayList<Card>(cards));
startActivity(i);
}
Retrieve it like this in the second activity
Bundle bundle = getIntent().getExtras();
List<Card> cards = (ArrayList<Card>)bundle.getParcelableArrayList("EXTRA_CARDS");

and the result that I got from looping Utils.log("studio_name: " + studio_name) are :
studio_name: Dodi fit
studio_name: inu fit
studio_name: Vstudio
studio_name: Infovendor
studio_name: Seleb Fitnes One
studio_name: Riri Studio
studio_name: NF Studio
It means I already got all of it use looping.
But the problem is the result did not populate into listview (it show as one one last result NF Studio, the other did not appear).
What I need is populate this into 4 texview from country_info (I disable imageview) :
String studio_name, address, website, seo_url
What is the correct code to show/populate that into listview?

Add the values into a List and pass it to the Adapter class of your ListView inside onPostExecute()

You don't need a thread, that's the whole point of async.
List View code is in the for loop
UI code belongs to PostExecute() not doInBackground()
You reinitialized the list inside of the loop
Try like this:
private class SendfeedbackJob extends AsyncTask<String, Void, String> {
private static final String LOG_TAG = "CariStudio";
private ArrayList<Country> countryList = new ArrayList<Country>();
ProgressDialog dialog;
Bundle extras = getIntent().getExtras();
final String token= extras.getString("TOKEN");
#Override
protected String doInBackground(String... params) {
String areaid = params[0];
Utils.log("params 1:"+ areaid);
// do above Server call here
ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("region_id", areaid ));
String responseString = null;
final String url_studio = Constant.URI_BASE_AVAILABLE_STUDIO+ "?token=" + token;
Utils.log("url studio:"+ url_studio);
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url_studio);
// no idea what this does :)
httppost.setEntity(new UrlEncodedFormEntity(postParameters));
// This is the line that send the request
HttpResponse response = httpclient.execute(httppost);
Utils.log("response:"+ response);
HttpEntity entity = response.getEntity();
String responseAsText = EntityUtils.toString(entity);
Utils.log("daftar isi studio: " + responseAsText);

Replacing JSON Populated TextView with JSON Populated ListView [duplicate]

This question already has an answer here:
JSON String is incorrectly mapped to textviews
(1 answer)
Closed 9 years ago.
I have a JSON request which returns a response from youtube containing the comments for a particular video. I currently have 3 textviews: one for the name/uploader, one for the content, and one for the date published - which are then populated with the data from my JSON response.
My problem is - only the first comment, date published and uploader appear.
I belive I'll need to replace my textviews with a list view and parse the 3 fields to it - I simply do not know how.

YouTubePlayer.OnInitializedListener {

uploaderTv.setText("by" + uploader + " |");
viewCountTv.setText(viewCount + " views");

<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="left"
android:text="" />
<TextView
android:id="#+id/content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/name"
android:layout_weight="1"

android:layout_below="#id/content"
android:layout_weight="1"

android:text="" />

Continuing my answer from your previous question # JSON String is incorrectly mapped to textviews
First you need a listview in your layout xml
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
Declare list as a instance variable
ArrayList<CommentsLibrary> list = new ArrayList<CommentsLibrary>();
Then
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name = jsonObject.optString("name","defaultValue");
String content = jsonObject.optString("content","defaultValue");
String published = jsonObject.optString("published","defaultValue");
list.add(new CommentsLibrary(name, content, published));
}
Then initialize listview
ListView lv =(ListView)findViewById(R.id.list);
CustomAdapter cus = new CustomAdapter(ActivityName.this,list);
lv.setAdapter(cus);
Define a custom layout with 3 textviews. (list_item.xml)
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="18dp"
android:layout_marginTop="31dp"
android:text="TextView" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/textView1"
android:layout_alignBottom="#+id/textView1"
android:layout_centerHorizontal="true"
android:text="TextView" />
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/textView2"
android:layout_alignBottom="#+id/textView2"
android:layout_alignParentRight="true"
android:layout_marginRight="24dp"
android:text="TextView" />
</RelativeLayout>
Then define a custom adapter by extending a base adapter. Override getView inflate the custom layout and set text views there.
public class CustomAdapter extends BaseAdapter
{
LayoutInfalter mInflater;
ArrayList<CommentsLibrary> list;
public CustomAdapter(Context context,ArrayList<CommentsLibrary> list)
{
mInflater = LayoutInfalter.from(context);
this.list = list;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder holder;
if(convertView==null)
{
convertView =minflater.inflate(R.layout.list_item, parent,false);
holder = new ViewHolder();
holder.tv1 = (TextView) convertView.findViewById(R.id.textView1);
holder.tv2 = (TextView) convertView.findViewById(R.id.textView2);
holder.tv3 = (TextView) convertView.findViewById(R.id.textView3);
convertView.setTag(holder);
}
else
{
holder= (ViewHolder) convertView.getTag();
}
holder.tv1.setText(list.get(position).getName());
holder.tv2.setText(list.get(position).getContent());
holder.tv3.setText(list.get(position).getPublished());
return convertView;
}
static class ViewHolder
{
TextView tv1,tv2,tv3
}
}

You need to add a list view in your layout and populate it using an ArrayAdapter. Here's a tutorial that shows you how - http://www.vogella.com/articles/AndroidListView/article.html#arrayAdapter
