I'm attempting to set up a TextAdapter for a String array. Basically it's a drop-down menu that holds a list of strings associated with the size of the item that the user wants to purchase.
private void SetupSpinner(String[] drawables) {
Spinner spinner = (Spinner) view.findViewById(R.id.spinner_sizes);
spinner.setAdapter(new ImageAdapter(getActivity(), R.layout.row, drawables));
}
public class ImageAdapter extends ArrayAdapter<String> {
private String[] drawables;
public ImageAdapter(Context context, int textViewResourceId, String[] drawables) {
super(context, textViewResourceId);
this.drawables = drawables;
}
#Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
return getView(position, convertView, parent);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView view = new TextView(getContext());
view.setText(Integer.parseInt(drawables[position]));
return view;
}
}
I had it working with drawables but that's inefficient. I don't want to make graphics for each of the size options. Anyway, all help greatly appreciated!
Create a xml custom_spinner
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical">
<TextView
android:id="#+id/text_main_seen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
<TextView
android:id="#+id/sub_text_seen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
Then put the spinner in your main xml where you need
<Spinner
android:id="#+id/spinner_show"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="100px"
android:drawSelectorOnTop="true" />
Then in your class
public class SpinnerCustomizationActivity extends Activity {
String[] spinnerValues = { "Blur", "NFS", "Burnout","GTA IV", "Racing", };
String[] spinnerSubs = { "Ultimate Game", "Need for Speed", "Ulimate Racing", "Rockstar Games", "Thunder Bolt" };
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Spinner mySpinner = (Spinner) findViewById(R.id.spinner_show);
mySpinner.setAdapter(new MyAdapter(this, R.layout.custom_spinner, spinnerValues)); }
public class MyAdapter extends ArrayAdapter<String> {
public MyAdapter(Context ctx, int txtViewResourceId, String[] objects)
{
super(ctx, txtViewResourceId, objects); }
#Override
public View getDropDownView(int position, View cnvtView, ViewGroup prnt) { return getCustomView(position, cnvtView, prnt); }
#Override
public View getView(int pos, View cnvtView, ViewGroup prnt)
{
return getCustomView(pos, cnvtView, prnt);
}
public View getCustomView(int position, View convertView, ViewGroup parent)
{
LayoutInflater inflater = getLayoutInflater();
View mySpinner = inflater.inflate(R.layout.custom_spinner, parent, false);
TextView main_text = (TextView)mySpinner.findViewById(R.id.text_main_seen);
main_text.setText(spinnerValues[position]);
TextView subSpinner = (TextView)mySpinner.findViewById(R.id.sub_text_seen);
subSpinner.setText(spinnerSubs[position]);
return mySpinner; }
}
}

I am using GridView to display a list but the grid return just one row .
How can I display all items in gridView?
My code :
<GridView
android:id="#+id/slide_item_rc_latest"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:verticalSpacing="5dp"
android:horizontalSpacing="5dp"
android:stretchMode="columnWidth"
android:numColumns="2"
/>
And my Adapter :
public class latestProductAdapter extends BaseAdapter {
private List<SlideItem> slideItems;
private Context mContext;
public latestProductAdapter(Context c, List<SlideItem> slideItems) {
mContext = c;
this.slideItems = slideItems;
}
#Override
public int getCount() {
return slideItems.size();
}
...
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolderItem viewHolder;
if (convertView == null) {
LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
convertView = inflater.inflate(R.layout.slid_item, parent, false);
...
}
return convertView;
}
}
In my activivty :
latestProductAdapter = new latestProductAdapter(getContext(), productListLatest);
LatestProductsGridView.setAdapter(latestProductAdapter);
Most possible reason could be you might be using grid view inside scroll view.
So remove scroll view or use other xml file to declare.
Please, help to figure out why view binding onItemClickListener doesn't work.
To be short: I'm loading list of fragments. And need to choose fragment to load by clicking to item, so I implemented AdapterView.OnItemClickListener for this purpose. But when I perform a click - nothing happens, method does't called.
public class ChooserFragment extends ListFragment implements AdapterView.OnItemClickListener {
private ChooserFragmentBinding mBinding;
private static final Class<?>[] CLASSES = new Class[]{
EmailPasswordFragment.class,
EmailPasswordFragment.class,
};
private static final int[] DESCRIPTION_IDS = new int[]{
R.string.desc_emailpassword,
R.string.desc_emailpassword,
};
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
mBinding = ChooserFragmentBinding.inflate(inflater, container, false);
View view = mBinding.getRoot();
CustomArrayAdapter adapter = new CustomArrayAdapter(getContext(), android.R.layout.simple_list_item_2, CLASSES);
adapter.setDescriptionIds(DESCRIPTION_IDS);
mBinding.list.setAdapter(adapter);
mBinding.list.setOnItemClickListener(this);
return view;
}
#Override
public void onDestroyView() {
super.onDestroyView();
mBinding = null;
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Class<?> clicked = CLASSES[position];
Log.d("Clicked", String.valueOf(position));
}
public static class CustomArrayAdapter extends ArrayAdapter<Class<?>> {
private Context mContext;
private int[] mDescriptionIds;
public CustomArrayAdapter(Context context, int resource, Class[] objects) {
super(context, resource, objects);
mContext = context;
}
#SuppressWarnings("NullableProblems")
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(android.R.layout.simple_list_item_1, null);
}
((TextView) view.findViewById(android.R.id.text1)).setText(mDescriptionIds[position]);
return view;
}
public void setDescriptionIds(int[] descriptionIds) {
mDescriptionIds = descriptionIds;
}
}
}
XML layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"

Thanks.
Is there some reason you have to have the Fragment extend ListFragment and implement AdapterView.OnItemClickListener? Try it the normal way and see what happens:
mBinding.list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.d("LOG", "test");
}
});
I'm trying to implement a selection activity for a given list of items. Each item is checkable, so I have an item with a TextView and a CheckBox. I implemented a ListView for displaying all the options and a Spinner for showing only the "Top Ten" choices, as a subset of the same list. For now I'm showing all the items in both ListView and Spinner.
I want for the items in the ListView to update when the user selects an item in the Spinner (Note: The reverse path works fine, as the Spinner grabs the updated ArrayList each time it dropsdown).
I tried to implement setOnItemSelectedListener for my Spinner, and to call notifyOnDataSetChanged() for my ListViewAdapter inside the Listener. But the Listener is only called on collapse and I get a weird (maybe unrelated) warning message.
The onItemSelectedListener for the Spinner only runs when the Spinner gets collapsed. But notifyOnDataSetChanged() seems to ignore the checked status of the items as a change. How can I make the first option run everytime I check an item and have the change get properly received by the ListAdapter?
Here's the Activity.java code:
public class TriageReasonActivity extends BaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_triage_reason);
final String[] select_qualification = {
"Select Qualification", "10th / Below", "12th", "Diploma", "UG",
"PG", "Phd"};
Spinner spinner = (Spinner) findViewById(R.id.top_reasons_spinner);
ListView symptoms_list = (ListView) findViewById(R.id.view_list_symptoms);
ArrayList<Symptoms> listVOs = new ArrayList<>();
for (int i = 0; i < select_qualification.length; i++) {
Symptoms reason = new Symptoms();
reason.setTitle(select_qualification[i]);
reason.setSelected(false);
listVOs.add(reason);
}
SymptomsListAdapter mListAdapter = new SymptomsListAdapter(this, 0,
listVOs);
SymptomsSpinnerAdapter mSpinnerAdapter = new SymptomsSpinnerAdapter(this, 0,
listVOs);
symptoms_list.setAdapter(mListAdapter);
spinner.setAdapter(mSpinnerAdapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
Log.i("Item selected", "but not cahnged");
symptoms_list.invalidateViews();
mListAdapter.notifyDataSetInvalidated();
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
Log.i("Not item selected", "but actually it did");
}
});
}
The SpinnerCustom Adapter code:
public class SymptomsSpinnerAdapter extends ArrayAdapter<Symptoms>{
private Context mContext;
private ArrayList<Symptoms> listState;
private SymptomsSpinnerAdapter myAdapter;
private boolean isFromView = false;
/*#Override
public void notifyDataSetChanged() {
super.notifyDataSetChanged();
//mNotifyOnChange = true;
}*/
public SymptomsSpinnerAdapter(Context context, int resource, List<Symptoms> objects) {
super(context, resource, objects);
this.mContext = context;
this.listState = (ArrayList<Symptoms>) objects;
this.myAdapter = this;
}
#Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
return getCustomView(position, convertView, parent);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
return getCustomView(position, convertView, parent);
}
public View getCustomView(final int position, View convertView,
ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
LayoutInflater layoutInflator = LayoutInflater.from(mContext);
convertView = layoutInflator.inflate(R.layout.item_reasons, null);
holder = new ViewHolder();
holder.mTextView = (TextView) convertView.findViewById(R.id.text);
holder.mCheckBox = (CheckBox) convertView.findViewById(R.id.checkbox);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.mTextView.setText(listState.get(position).getTitle());
// To check weather checked event fire from getview() or user input
isFromView = true;
holder.mCheckBox.setChecked(listState.get(position).isSelected());
isFromView = false;
if ((position == 0)) {
holder.mCheckBox.setVisibility(View.INVISIBLE);
} else {
holder.mCheckBox.setVisibility(View.VISIBLE);
}
holder.mCheckBox.setTag(position);
holder.mCheckBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int getPosition = (Integer) buttonView.getTag();
if (!isFromView) {
listState.get(position).setSelected(isChecked);
}
}
});
return convertView;
}
#Override
public int getCount() {
return listState.size();
}
#Override
public Symptoms getItem(int position) {
if( position < 1 ) {
return null;
}
else {
return listState.get(position-1);
}
}
#Override
public long getItemId(int position) {
return 0;
}
private class ViewHolder {
private TextView mTextView;
private CheckBox mCheckBox;
}
}
Here's the (almost identical) ListAdapter:
public class SymptomsListAdapter extends BaseAdapter implements ListAdapter {
private Context mContext;
private ArrayList<Symptoms> listState;
private boolean isFromView = false;
public SymptomsListAdapter(Context context, int resource, List<Symptoms> objects) {
this.mContext = context;
this.listState = (ArrayList<Symptoms>) objects;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
return getCustomView(position, convertView, parent);
}
public View getCustomView(final int position, View convertView,
ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
LayoutInflater layoutInflator = LayoutInflater.from(mContext);
convertView = layoutInflator.inflate(R.layout.item_reasons, null);
holder = new SymptomsListAdapter.ViewHolder();
holder.mTextView = (TextView) convertView.findViewById(R.id.text);
holder.mCheckBox = (CheckBox) convertView.findViewById(R.id.checkbox);
convertView.setTag(holder);
} else {
holder = (SymptomsListAdapter.ViewHolder) convertView.getTag();
}
holder.mTextView.setText(listState.get(position).getTitle());
// To check weather checked event fire from getview() or user input
isFromView = true;
holder.mCheckBox.setChecked(listState.get(position).isSelected());
isFromView = false;
if ((position == 0)) {
holder.mCheckBox.setVisibility(View.INVISIBLE);
} else {
holder.mCheckBox.setVisibility(View.VISIBLE);
}
holder.mCheckBox.setTag(position);
holder.mCheckBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int getPosition = (Integer) buttonView.getTag();
if (!isFromView) {
listState.get(position).setSelected(isChecked);
}
}
});
return convertView;
}
#Override
public int getCount() {
return listState.size();
}
#Override
public Symptoms getItem(int position) {
if( position < 1 ) {
return null;
}
else {
return listState.get(position-1);
}
}
#Override
public long getItemId(int position) {
return 0;
}
private class ViewHolder {
public TextView mTextView;
public CheckBox mCheckBox;
}
}
And here's the warning I'm getting:
W/art: Before Android 4.1, method int android.support.v7.widget.DropDownListView.lookForSelectablePosition(int, boolean) would have incorrectly overridden the package-private method in android.widget.ListView
EDIT: Adding the layouts and the model class in case they may cause an issue:

The reason that nothing is changing is because you haven't implemented the method to handle the data set changes. You need to handle how the data is reloaded in your adapter:
public class SymptomsListAdapter extends BaseAdapter implements ListAdapter {
...
public void refreshData(ArrayList<Symptoms> objects){
this.listState = (ArrayList<Symptoms>) objects;
notifyDataSetChanged();
}
...
}
This link does a great job of explaining how the notifyDataSetInvalidated() works (or in your case, why it's not working).
I am new for Android development.
I was trying to implement a custom ArrayAdapter to accept custom object in Android Studio.
I have referenced the source code from some tutorial, but my screen output was improper that the custom object only fill in the TextView which link with the textViewResourceId of ArrayAdapter , but not the custom object's properties fill in all EditText in the layout appropriately.
I tried to remove textViewResourceId parameter in the constructor of ArrayAdapter to fix the problem, but Android Studio returned error - You must supply a resource ID for a TextView
I want the properties of custom object fill in all EditText and no error message be returned, can anyone give me a hint?
Here is my layout:
row_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/row_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"/>
<EditText
android:id="#+id/row_no"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_margin="1dp"
android:layout_gravity="center_horizontal"
android:background="#color/colorWhite"/>
<EditText
android:id="#+id/row_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_margin="1dp"
android:layout_gravity="center_horizontal"
android:background="#color/colorWhite"/>
</LinearLayout>
Here is my custom object:
Row.java
public class Row
{
public int RowNo;
public String RowText;
public Row(int no, String text)
{
this.RowNo = no;
this.RowText = text;
}
}
Here is my custom ArrayAdapter:
RowAdapter.java
public class RowAdapter extends ArrayAdapter<Row> {
private final Activity _context;
private final ArrayList<Row> rows;
static class ViewHolder
{
EditText RowNo;
EditText RowText;
}
public RowAdapter(Activity context, ArrayList<Row> rows)
{
super(context,R.layout.row_layout, R.id.row_id ,rows);
this._context = context;
this.rows = rows;
}
public View GetView(int position, View convertView, ViewGroup parent){
ViewHolder holder = null;
if(convertView == null)
{
LayoutInflater inflater = _context.getLayoutInflater();
convertView = inflater.inflate(R.layout.row_layout,parent,false);
holder = new ViewHolder();
holder.RowNo = (EditText)convertView.findViewById(R.id.row_no);
holder.RowText = (EditText)convertView.findViewById(R.id.row_text);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.RowNo.setText(rows.get(position).RowNo);
holder.RowText.setText(rows.get(position).RowText);
return convertView;
}
}
Here is my Activity class:
RowActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.row_list_page);
listView = (ListView)findViewById(R.id.list_view);
ArrayList<Row> rows = new ArrayList<Row>();
rows.add(new Row(1,"Test"));
rows.add(new Row(2,"Test"));
rows.add(new Row(3"Test"));
RowAdapter adapter = new RowAdapter(this,rows);
listView.setAdapter(adapter);
}
Here is working adapter code
public class RowAdapter extends ArrayAdapter<Row> {
private final Activity _context;
private final ArrayList<Row> rows;
public class ViewHolder
{
EditText RowNo;
EditText RowText;
}
public RowAdapter(Activity context, ArrayList<Row> rows)
{
super(context,R.layout.row_layout, R.id.row_id ,rows);
this._context = context;
this.rows = rows;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
ViewHolder holder = null;
if(convertView == null)
{
LayoutInflater inflater = _context.getLayoutInflater();
convertView = inflater.inflate(R.layout.row_layout,parent,false);
holder = new ViewHolder();
holder.RowNo = (EditText)convertView.findViewById(R.id.row_no);
holder.RowText = (EditText)convertView.findViewById(R.id.row_text);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.RowNo.setText(""+rows.get(position).RowNo);
holder.RowText.setText(rows.get(position).RowText);
return convertView;
}
}
Your getting exception at holder.RowNo.setText(rows.get(position).RowNo);
so replace it with
holder.RowNo.setText(""+rows.get(position).RowNo);
Change with below code:-
RowAdapter.java
public class RowAdapter extends BaseAdapter {
private final Context _context;
private final ArrayList<Row> rows;
public RowAdapter(Context context, ArrayList<Row> rows)
{
this._context = context;
this.rows = rows;
}
#Override
public int getCount() {
return rows.size();
}
#Override
public Object getItem(int position) {
return rows;
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent){
LayoutInflater inflater = (LayoutInflater) _context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView=inflater.inflate(R.layout.row_layout, null,true);
EditText RowNo = (EditText) rowView.findViewById(R.id.row_no);
EditText RowText = (EditText) rowView.findViewById(R.id.row_text);
RowNo.setText(rows.get(position).RowNo);
RowText.setText(rows.get(position).RowText);
return rowView;
}
}
public View getView (int position, View convertView, ViewGroup parent)
This method is called to get view object.
In your code there is GetView, not getView
change your
public View GetView(int position, View convertView, ViewGroup parent)
with
#Override
public View getView(int position, View convertView, ViewGroup parent)
and
holder.RowNo.setText(rows.get(position).RowNo);
with
holder.RowNo.setText(""+rows.get(position).RowNo);

ResivedSMS.java:50 is:

Whats my code problem and how to resolved Thanks?
problem:
inflater.inflate(R.layout.list_fragment, container, false);
You are inflating a LinearLayout not a ListView thus giving you ClassCastException
solution:
Since you are using ListFragment you can directly set the adapter, since ListFragment has its own default ListView. Set the adapter in the onCreate Method.
sample:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ViewResivedSMSDetailes customListView = new ViewResivedSMSDetailes(getActivity(),testArray1,testArray2);
setListAdapter( customListView ); //call the method if listFragment
}
