RadioGroup listener dont work

RadioGroup listener dont work - android

I have a Fragment that displays a Dialog.
Inside that Dialog there is a RadioGroup.
I tried to create a listener to this RadioGroup, but i didn't successed.
Fragment --> Dialog --> RadioGroup
I tried four ways:
OnCheckedChangeListener on RadioGroup.
OnClickListener on RadioGroup.
OnCheckedChangeListener on RadioButton.
OnClickListener on RadioButton
No one worked.
Here is my code:
The Dialog - layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<RadioGroup
android:id="#+id/bS_rg"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:orientation="vertical">
<RadioButton
android:id="#+id/r_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="ID"
android:textSize="24sp" />
<RadioButton
android:id="#+id/r_title"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Title"
android:textSize="24sp" />
<RadioButton
android:id="#+id/r_genre"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Genre"
android:textSize="24sp" />
<RadioButton
android:id="#+id/r_author"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Author"
android:textSize="24sp" />
</RadioGroup>
<AutoCompleteTextView
android:id="#+id/c_bSearch"
android:layout_width="278dp"
android:layout_height="72dp"
android:singleLine="true"/>
</LinearLayout>
The Fragment - layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

<de.codecrafters.tableview.TableView
android:id="#+id/tableView"
android:layout_width="wrap_content"

</RelativeLayout>
And the Fragment - code: (I marked where is the problem, the other code is not important)
package com.example.adiel.library_app_30;

RadioButton state and Button validation

I am facing two issues.
Radio buttons in radiogroup loosing state: when I click yes or no and scroll down the list view it looses the radiobutton value which is checked. I tried many ways to fix it but unable to achieve.
Submit button validation(Please refer image four): list of questions user should select either yes or no before clicking on submit button, if user click on submit button without selecting either yes or no it should them a toast message. all the questions should be selected with either yes or no. More specific each radiogroup should give me yes or no, not empty string.
Thanks in advance.

Try this.
Use ViewHolder so it does not lose the data set
Custom Adapter class
#Override

if(view == null){
view = inflter.inflate(R.layout.list_items, null);
viewHolder = new ViewHolder();
ViewHoldwe.question = (TextView) view.findViewById(R.id.question);
viewHolder.yes = (RadioButton) view.findViewById(R.id.yes);
viewHolder.no = (RadioButton) view.findViewById(R.id.no);
viewHolder.rg = (RadioGroup) view.findViewById(R.id.radio_group);
view.setTag(viewHolder)
}else{
viewHolder = (ViewHolder) view.getTag();
viewHolder.rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (viewHolder.yes.isChecked()) {
viewHolder.yes.setBackgroundColor(Color.GREEN);
viewHolder.no.setBackgroundColor(Color.BLACK);
}
if (viewHolder.no.isChecked()){
viewHolder.no.setBackgroundColor(Color.rgb(255,165,0));
viewHolder.yes.setBackgroundColor(Color.BLACK);
}
}
});
viewHolder.yes.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked)
selectedAnswers.set(i, "1");
}
});
viewHolder.no.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked)
selectedAnswers.set(i, "2");
}
});
question.setText(questionsList[i]);
}
return view;
}
Make a private inner class
private class ViewHolder{
RadioButton yes;
TextView question;
RadioButton no ;
RadioGroup rg;
}

1. Try to call method configViews() from onCreateView() and pass the view kf06_view as parameter.
2. Implement View.OnClickListener to handle button_kf06_back and button_kf06_next click events.
Update your K06_Away Fragment as below:
public class K06_Away extends Fragment implements View.OnClickListener {
protected Typeface tfLatoBold,tfLatoMedium,tfLatoRegular;
private Button button_kf06_back,button_kf06_next;
private TextView txtVw_kf06_resident_away;
private EditText edTxt_kf06_visiting_lastname;
private RadioGroup radioGp_kf06_resident_away;
List<RadioButton> radioButtons = new ArrayList<RadioButton>();
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View kf06_view = inflater.inflate(R.layout.k06_away, container, false);
// Init
configViews(kf06_view);
return kf06_view;
}
private void configViews(View view) {
button_kf06_back = (Button) view.findViewById(R.id.button_kf06_back);
button_kf06_next = (Button) view.findViewById(R.id.button_kf06_next);

radioGp_kf06_resident_away = (RadioGroup) view.findViewById(R.id.radioGp_kf06_resident_away);
radioButtons.add( (RadioButton) view.findViewById(R.id.radio_kf06_1_2_hours) );

radioButtons.add( (RadioButton) view.findViewById(R.id.radio_kf06_allday) );
radioButtons.add( (RadioButton) view.findViewById(R.id.radio_kf06_moreday) );
configClickListeners();
radioButtonAction();
}
#Override
public void onClick(View v) {

}
private void configClickListeners() {
button_kf06_back.setOnClickListener(this);

RadioGroup Directly contain only RadioButtons,No other Layouts,if you add LinearLayout inside RadioGroup,it will not works as you expect.Only use RadioButtons as child of RadioGroup.

How do I replace my popupmenu code with ListPopupWindow?

Currently , I am programatically creating a popupmenu which displays a list of floors and a title. However, changing the background color of just the title and adding a close button to title is turning out to be a nightmare.
I want to replace this popupmenu with a list popup window so I can add an XML file with background attribute for the title with a black color as the background and a close button on the right and white background for items in the menu. Is there a way I can achieve this with list popup window? Here's my code for that:
private void floorMenu(ImageView btnFloorMenu){
MapData data = new MapDao(MyPlugin.mapId);
final List<Floor> flList = dao.getFloors();
// set popupMenu
final PopupMenu floorsPm = new PopupMenu(MapViewActivity.this,btnFloorMenu);
MenuItem titleItem = floorsPm.getMenu().add(Menu.NONE, Menu.NONE, Menu.NONE, "Floors");
int i = 1;
for(Floor fl : flList)
{
floorsPm.getMenu().add(Menu.NONE, i,i, fl.getName());
if(i>3)
break;
i++;
}
// add popup listener
floorsPm.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
// onClick
#Override
public boolean onMenuItemClick(MenuItem item){
// get floorname
int flOrder = item.getOrder();
if(flOrder == Menu.NONE )
return true;
flOrder--;
final String floorId = flList.get(flOrder).getMapId();
// set camera to floor
runOnUiThread(new Runnable() {
#Override
public void run() {
floorsPm.dismiss();
mapFragment.getMapManager().setCameraLayer(floorId, false);
Log.d(TAG, "post cameraLayer set");
changedSteps = true;
pauseNav();
}
});
return true;
}
});
floorsPm.show();
}

Here is my example to create show a ListPopupWindow
First, create layout item_list_popup_window for each item of ListPopupWindow
<?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="wrap_content"
android:background="#e4e4e4"
android:paddingTop="1dp"
android:orientation="horizontal">
<TextView
android:id="#+id/text_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1" />
<Button
android:id="#+id/button_delete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Delete" />
</LinearLayout>
Second, create an Adapter for your ListPopupWindow like
public class ListPopupWindowAdapter extends BaseAdapter{
private Activity mActivity;
private List<String> mDataSource = new ArrayList<>();
private LayoutInflater layoutInflater;
private OnClickDeleteButtonListener clickDeleteButtonListener;
ListPopupWindowAdapter(Activity activity, List<String> dataSource, #NonNull OnClickDeleteButtonListener clickDeleteButtonListener){
this.mActivity = activity;
this.mDataSource = dataSource;
layoutInflater = mActivity.getLayoutInflater();
this.clickDeleteButtonListener = clickDeleteButtonListener;
}
#Override
public int getCount() {
return mDataSource.size();
}
#Override
public String getItem(int position) {
return mDataSource.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if(convertView == null){
holder = new ViewHolder();
convertView = layoutInflater.inflate(R.layout.item_list_popup_window, null);
holder.tvTitle = (TextView) convertView.findViewById(R.id.text_title);
holder.btnDelete = (Button) convertView.findViewById(R.id.button_delete);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
// bind data
holder.tvTitle.setText(getItem(position));
holder.btnDelete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
clickDeleteButtonListener.onClickDeleteButton(position);
}
});
return convertView;
}
public class ViewHolder{
private TextView tvTitle;
private Button btnDelete;
}
// interface to return callback to activity
public interface OnClickDeleteButtonListener{
void onClickDeleteButton(int position);
}
}
Third, You create a function for create and show ListPopupWindow
private void showListPopupWindow(View anchorView) {
final ListPopupWindow listPopupWindow = new ListPopupWindow(this);
listPopupWindow.setWidth(600);
List<String> sampleData = new ArrayList<>();
sampleData.add("A");
sampleData.add("B");
sampleData.add("CCCCCCCCCCCCCC");
sampleData.add("D");
sampleData.add("EEEEEEEEE");
listPopupWindow.setAnchorView(anchorView);
ListPopupWindowAdapter listPopupWindowAdapter = new ListPopupWindowAdapter(this, sampleData, new ListPopupWindowAdapter.OnClickDeleteButtonListener() {
#Override
public void onClickDeleteButton(int position) {
Toast.makeText(MainActivity.this, "Click delete " + position, Toast.LENGTH_SHORT).show();
listPopupWindow.dismiss();
}
});
listPopupWindow.setAdapter(listPopupWindowAdapter);
listPopupWindow.show();
}
Finally, you can show the ListPopupWindow by
showListPopupWindow(v);
for example, if you want to show it when click button
anyButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showListPopupWindow(v);
}
});
Full Demo is here

Please Try this code, Maybe you wont like this
private void floorMenu(ImageView btnFloorMenu){
final Dialog customDialog = new Dialog(this);
customDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
customDialog.setContentView(R.layout.item_dialog_coustom_design);
TextView clickItem = (TextView)customDialog.findViewById(R.id.item_click);
TextView clickItem1 = (TextView)customDialog.findViewById(R.id.item_click1);
TextView clickItem2 = (TextView)customDialog.findViewById(R.id.item_click2);
Button btnClose = (Button)customDialog.findViewById(R.id.btn_close);
clickItem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
customDialog.dismiss();
// wright your Button Action
}
});
clickItem1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
customDialog.dismiss();
// wright your Button Action
}
});
clickItem2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
customDialog.dismiss();
// wright your Button Action
}
});
btnClose.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
customDialog.dismiss();
}
});
customDialog.show();
}
Create Linearlayout layout_width="280dp" layout_height="wrap_content"
android:orientation="vertical" file name item_dialog_coustom_design.xml then put this code
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Title"
android:background="#000"
android:textColor="#fff"
android:padding="12dp"
android:textSize="20sp"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dp"
android:background="#fff"
android:padding="10dp"
android:text="Your Item"
android:id="#+id/item_click"
android:textSize="16sp" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dp"
android:background="#fff"
android:padding="10dp"
android:text="Your Item"
android:id="#+id/item_click1"
android:textSize="16sp" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dp"
android:background="#fff"
android:padding="10dp"
android:text="Your Item"
android:id="#+id/item_click2"
android:textSize="16sp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="10dp"
android:paddingRight="10dp"
android:paddingBottom="10dp"
android:background="#fff"
android:gravity="right">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/btn_close"
android:text="Close"/>
</LinearLayout>

How to get value of all selected radio buttons from all the views in sliding Fragment

I have three views in sliding Fragment with Survey Questions having dynamic radiobuttons (the layout for all views are same, i am just repeating). I can get the data of selected radiobuttons from one screen, but how can i get the data of all selected radiobuttons from all screens ? Below is my working code

Android opOptionsItemSelected menu doesn't work

I have a problem with a menu in my Android app: it displays when I click the button, but when I try to click the option which will start another activity, it does nothing. It doesn't crash, either.
Here's the code for the menu:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.bookmark:
this.item.setBookmark(!this.item.getBookmarks()) ;
if(this.item.getBookmarks()){
bookmark.setImageResource(R.drawable.favorito1);
}
else{
bookmark.setImageResource(R.drawable.favorito);
}
return true;
case R.id.settings:
Intent settings = new Intent(this,Settings.class);
startActivity(settings);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
And here's the full code of my activity:
public class EventList extends Activity implements OnClickListener {
ImageView bookmark;
ImageView palau;

Thank you very much.

Try adding this to EventList.java:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
case R.id.settings:
Intent settingsIntent = new Intent(this, Settings.class);
startActivity(settingsIntent);
return true;
}
}

can you please paste your event.xml as well as is Settings.class extending PreferenceActivity ?
Also this is happening sometimes if your are using eclipse. Just clean try to clean and rebuild your project.
if it wont work, then try:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.createOnOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.event, menu);
return true;
}
