Spinner BaseAdapter(android)

Spinner BaseAdapter(android) - java

Sorry for my English. As research, I want to try to use the spinner with baseAdapter. But I do not know why I spinner does not output anything.
Its xml:
student_list_questions.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/listsQuestions"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp" >
</ListView>
</LinearLayout>
student_list.xml
<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
android:layout_width="match_parent"

android:id="#+id/s_spinner_rating"
android:layout_width="90dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
</LinearLayout>
And my Class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.student_list_questions);
Spinner sp = new Spinner(this);
SpinnerBaseAdapter adapter = new SpinnerBaseAdapter(this, new ArrayList<String>());
sp.setAdapter(adapter);
//then code
}
And this spinner adapter:
public class SpinnerBaseAdapter extends BaseAdapter {
private List<String> numberList;
private LayoutInflater mInflater;
#SuppressWarnings("unchecked")
public SpinnerBaseAdapter(Context context, Object results) {
numberList = (List<String>) results;
numberList.add("1");
numberList.add("2");
numberList.add("3");
mInflater = LayoutInflater.from(context);
}
#Override

}
#Override

return numberList.get(position);
}
#Override

#Override

if(convertView == null) {

ListView CustomAdapter not showing first position results

I'm new to Android Studio and coding in general and I am trying to display a custom ListView with an image of a colour and the name of the colour. I have used a custom Adapter to inflate the view with two arrays containing the drawable image colours and string of the names.
The problem I am having - the custom adapter is only displaying the layers from position 1 and onwards. For example, where the first layer should be img_01 and "red" - it is displaying img_02 and "Orange".
I've tried debugging the code and it seems that though the adapter is setting the values for position 0, but I cannot find the reason why it is not displaying (as the others are displaying fine).
The images & names are just placeholders, so an alternative solution that doesn't include both the drawables and names wouldn't be viable,
Thank you in advance
CustomAdapter.java
public class CustomAdapter extends BaseAdapter {
Context context;
int[] images;
String[] colour;
LayoutInflater mInflater;
public CustomAdapter(Context c, int[] i, String[] col) {
this.context = c; //sets the application context that has been passed to the adapter
this.images = i; //sets the images array that has been passed to the adapter
this.colour = col; //sets the colour array that has been passed to the adapter
mInflater = (LayoutInflater.from(context)); //sets the layout inflater from context
}
#Override
public int getCount() { //total number of elements in the array
return images.length;
}
#Override
public Object getItem(int position) { //gets the item using the position
return null;
}
#Override
public long getItemId(int position) { //gets the item position
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) { //this is used to update the view
convertView = mInflater.inflate(R.layout.custom_layout, null);
ImageView image = convertView.findViewById(R.id.imageView);
TextView text = convertView.findViewById(R.id.textView);
text.setText(colour[position]);
image.setImageResource(images[position]);
return convertView;

Try to set the height of the ListView to wrap_content instead of hardcoding it
<ListView
...
android:layout_height="wrap_content"/>

You can do it with RecyclerView.
Create a custom class
public class ExampleItem {
private int mImageResource; //your color image
private String mText1; //your text
public ExampleItem(int imageResource, String text1) {
mImageResource = imageResource;
mText1 = text1;
}
public int getImageResource() {
return mImageResource;
}
public String getText1() {
return mText1;
}
}
Create a XML layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"
app:cardCornerRadius="4dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="4dp">
<ImageView
android:id="#+id/imageView"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="2dp" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toEndOf="#+id/imageView"
android:text="Line 1"
android:textColor="#android:color/black"
android:textSize="20sp"
android:textStyle="bold" />
</RelativeLayout>
</android.support.v7.widget.CardView>
Create a Recycler View Adapter
public class ExampleAdapter extends RecyclerView.Adapter<ExampleAdapter.ExampleViewHolder> {
private ArrayList<ExampleItem> mExampleList;
public static class ExampleViewHolder extends RecyclerView.ViewHolder {
public ImageView mImageView;
public TextView mTextView1;
public ExampleViewHolder(View itemView) {
super(itemView);
mImageView = itemView.findViewById(R.id.imageView);
mTextView1 = itemView.findViewById(R.id.textView);
}
}
public ExampleAdapter(ArrayList<ExampleItem> exampleList) {
mExampleList = exampleList;
}
#Override
public ExampleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.example_item, parent, false);
ExampleViewHolder evh = new ExampleViewHolder(v);
return evh;
}
#Override
public void onBindViewHolder(ExampleViewHolder holder, int position) {
ExampleItem currentItem = mExampleList.get(position);
holder.mImageView.setImageResource(currentItem.getImageResource());
holder.mTextView1.setText(currentItem.getText1());
}
#Override
public int getItemCount() {
return mExampleList.size();
}
}

Spinner's style is changed once i open it for the second

I am developing an app where I show a dropdownlist using a spinner.
I used a custom adapter, here is the code:
public class DemandeCongeAdapter extends BaseAdapter {
public static final String TAG = "DemandeCongeAdapter";
private final Context mContext;
private List<DemandeCongeType> mData;
protected LayoutInflater mInflater;
public DemandeCongeAdapter(Context mContext, List<DemandeCongeType> mData) {
this.mContext = mContext;
this.mData = mData;
this.mInflater = LayoutInflater.from(mContext);
}
static class ViewHolder {
public ViewHolder(View v) {
typedeDemandeName = (TextView) v.findViewById(R.id.type_demande_name);
}
protected final TextView typedeDemandeName;
}
#Override
public int getCount() {
return mData.size();
}
#Override
public DemandeCongeType getItem(int position) {
return mData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.layout_create_demande_conge_custom_spinner, parent, false);
viewHolder = new ViewHolder(convertView);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
if (position != 0) {
DemandeCongeType item = getItem(position);
String name = item.getTypdeDemandeName() == null ? "" : item.getTypdeDemandeName();
viewHolder.typedeDemandeName.setText(name);
}
return convertView;
}
}
And for the activity code, here is it:
private List<DemandeCongeType> congeTypes;
private DemandeCongeAdapter spinnerCongeTypeArrayAdapter;
congeTypes.addAll(new ArrayList<>((List<DemandeCongeType>) responseBody));
congeTypes.add(0, new DemandeCongeType());
spinnerCongeTypeArrayAdapter = new
DemandeCongeAdapter(DemandeCongeNewActivity.this, congeTypes);
congeTypeSpinner.setAdapter(spinnerCongeTypeArrayAdapter);
congeTypeSpinner.setSelection(Adapter.NO_SELECTION, false);
Everything works fine, but when I select the spinner for the first time, it shows the list correctly like this:
Once I click outside the spinner and I click for the second time on the spinner, I got it like this:
So I can't the find the problem, please if anyone can help me with that.
Here is the XML code:
<Spinner
android:id="#+id/spinner_type_conge"
fontPath="fonts/light.otf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:background="#null"
android:dropDownWidth="match_parent"
android:ellipsize="end"
android:lines="1"
android:paddingRight="2dp"
android:spinnerMode="dropdown"
android:textSize="13sp" />
And for the spinner item xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/type_demande_name"
fontPath="fonts/light.otf"

android:ellipsize="marquee"
android:lines="1"
android:padding="10dp"
android:textColor="#color/annuaire_hint_color"
android:textSize="13sp" />

Try This way i have use this in my Application.
XML Design Code.
Spinner set in your Activity
<Spinner
android:id="#+id/sp_pen_Category"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

This is Java code when you fill spinner.
ArrayAdapter<String> adp_sp = new ArrayAdapter<String>(Activity.this, R.layout.sp_items, arr_spinner);
adp_sp.setDropDownViewResource(R.layout.sp_list);
sp_pen_Category.setAdapter(adp_sp);

Custom GridView Adapter not displaying

I'm creating a list of "channels" on an app that users can select. I want them in a grid view, (kind of like clickable tiles). There are supposed to be two separate Grids on this Fragment - default channels (channelListSupplied) and ones that the user will have to request subscriptions to (channelListEarned).
I used a custom adapter that I got from another answer here on SO, but I can't get it to work because it's in a Fragment instead of in the Activity, and I'm sure there's some reference I'm not passing correctly.
Below is a list of the relevant pieces of Java and XML...
FragmentChannels.java: (fragment to MainActivity.java)
public class FragmentChannels extends Fragment implements FragmentManager.OnBackStackChangedListener {
ViewGroup container;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
...
final JSONObject channelList = data.getJSONObject("channels");
final JSONArray channelListSupplied = channelList.getJSONArray("supplied");
final JSONArray channelListEarned = channelList.getJSONArray("earned");
GridView channelViewSupplied = (GridView) view.findViewById(R.id.channel_grid_supplied);
GridView channelViewEarned = (GridView) view.findViewById(R.id.channel_grid_earned);
if (Session.getSessionVar("canHasSpecial").equals("1")) {
FragmentChannels.this.createGridView(channelViewEarned, channelListEarned, FragmentChannels.this.container);
}
FragmentChannels.this.createGridView(channelViewSupplied, channelListSupplied, FragmentChannels.this.container);
...
return view;
}
public void createGridView(final GridView gridView, JSONArray list, final ViewGroup container) throws JSONException {
final String[] gridList = new String[list.length()];
final Activity activity = getActivity();
for (int i = 0; i < list.length(); i++) {
JSONObject channelData = (JSONObject) list.get(i);
gridList[i] = channelData.getString("source_name");
}
activity.runOnUiThread(new Runnable() {
#Override
public void run() {
gridView.setAdapter(new GridViewAdapter(activity, gridList, container));
}
});
}

inflater.inflate(R.menu.menu_channels, menu);

As of now, nothing displays on the Fragment except the "My Channels" TextView.
I greatly appreciate any help!

Fixed.
I changed the line:
gridView = inflater.inflate(R.layout.grid_item_layout, this.container);
To:
gridView = inflater.inflate(R.layout.grid_item_layout, null);
in the GridViewAdapter.java class.

I have tried most of the solutions regarding this topic on StackOverFlow none of them worked for me. This app lists all the images but when you click onItemClick isnt fired. Probably there is something wrong with my code.
Thank you!!

Remove android:clickable="true" in row_grid.xml. and add android:clickable="true" in activity_main.xml
Also remove the
android:focusable="false"
android:focusableInTouchMode="false"
As row_grid.xml is clickable, it blocks the grid's onclick listener from responding.
