I want to put button below ListView and have everything inside ScrollView(not only ListView should be scrollable but button too so if ListView has a lot of elements button is invisible and user has to scroll down to click it).
My xml is:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.plan.aplikacjamobilna.fragments.tabs.Allergies">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="center_horizontal">
<ListView
android:id="#+id/allergies_listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:dividerHeight="3dp"
android:divider="#cccccc">
</ListView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"/>
</LinearLayout>
</ScrollView>
it looks like:
I'm not sure why it doesn't work, there is "match_parent" as layout_hight.
What shuld I change in my code?

You can use this function to set the height of list view based on your children.
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
Example:
setListViewHeightBasedOnChildren(yourlistview);
A ListView is scrollable on it's own and should not be wrapped in a ScrollView. For your use, what you should do is to simply have the ListView as it is and have the button as the last view in the ListView. You will have to modify the getview() method in your adapter to achieve this. Based on the index, you will return a view that displays a Button.
I suggest you to use RecyclerView with footer as a button like this way,and also try HFRecyclerView
public class HeaderFooterAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private static final int TYPE_HEADER = 0;
private static final int TYPE_ITEM = 1;
private static final int TYPE_FOOTER = 2;
ArrayList<Generic> generics;
Context context;
public HeaderFooterAdapter(Context context, ArrayList<Generic> generics) {
this.context = context;
this.generics = generics;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder (ViewGroup parent, int viewType) {
if(viewType == TYPE_HEADER) {
View v = LayoutInflater.from (parent.getContext ()).inflate (R.layout.header_item, parent, false);
return new HeaderViewHolder (v);
} else if(viewType == TYPE_FOOTER) {
View v = LayoutInflater.from (parent.getContext ()).inflate (R.layout.footer_item, parent, false);
return new FooterViewHolder (v);
} else if(viewType == TYPE_ITEM) {
View v = LayoutInflater.from (parent.getContext ()).inflate (R.layout.list_item, parent, false);
return new GenericViewHolder (v);
}
return null;
}
private Generic getItem (int position) {
return generics.get (position);
}
#Override
public void onBindViewHolder (RecyclerView.ViewHolder holder, int position) {
if(holder instanceof HeaderViewHolder) {
HeaderViewHolder headerHolder = (HeaderViewHolder) holder;
headerHolder.txtTitleHeader.setText ("Header");
headerHolder.txtTitleHeader.setOnClickListener (new View.OnClickListener () {
#Override

});
} else if(holder instanceof FooterViewHolder) {

When i choose an item from listview, it turns gray but when I select another item in the listview then the previous highlighted item turns to default color and the new item turns to gray. What I want is to stay both of them to be highlighted, and when a click on the highlighted items they should turn back to normal as well.
My code:

How can i achive that functionality?
First, add a field conversationSelected in the Conversation class.
You should useRecyclerView instead of ListView.
You can refer to the official documentation to get started with RecyclerView.
When you have your RecyclerView, you can define the Adapter in this way:
public class ConversationAdapter extends RecyclerView.Adapter<ConversationAdapter.ViewHolder> {
List<Conversation> conversations;
public ConversationAdapter(List<Conversation> conversations) {
this.conversations = conversations;
}
public ConversationAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
TextView v = (TextView) LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_view, parent, false);
...
MyViewHolder vh = new MyViewHolder(v);
return vh;
}
// Replace the contents of a view (invoked by the layout manager)
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Conversation conversation = conversations.get(position);
holder.mTextView.setText(conversation.getConversationText());
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
return conversations.size();
}
public static class MyViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
public TextView mTextView;
public MyViewHolder(TextView v) {
super(v);
mTextView = v;
}
}
Next step: add item click listener to the RecyclerView: I struggled a little bit before see this answer which helps me to solve the problem: RecyclerView click Listener
In the clickListener you have to change the state conversationSelected of the Conversation in the conversations list (not inside the ViewHolder) to true.Then when you need to retrieve the selected conversation you have only to check this value.
I have RecycleView List with an ExpandableLinearLayout ( i use a third party library). In my ExpandableLinearLayout I have a ListView, with an custom ArrayAdapter.
I set my Adapter in the RecycleViewAdapter and submit one ArrayList that contains 4 ArrayLists and the position from the onBindViewHolder() method , too fill the different sections in the RecycleView.
I pass the data in the correct section but i get only the first element of each ArrayList. I Log some stuff and the problem is the position from the getView method in my ArrayAdapter is always 0..
I search and played around a bit but i didnt found a solution.. I hope somebody can help..
Sorry for my bad grammar

I have stored some value in arraylist if checkbox is clicked but i am having a difficult time to get it from listView class. How can i get it. Also if I keep
clickListener in view that contains checkbox and textView, the checkbox click is not working but if i click in textview it works. How to fix it. Below is my code.

final Holder holder=new Holder();
View rowView;
rowView = inflater.inflate(R.layout.singlerow_compare, null);
holder.tv=(TextView) rowView.findViewById(R.id.textViewCompare);
holder.checkBox = (CheckBox) rowView.findViewById(R.id.imageViewCompare);
holder.tv.setText(result.get(i).toString());
holder.checkBox.setButtonDrawable(imageId[i]);
final String selectedCbValue = holder.tv.getText().toString();
holder.checkBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
boolean checked = ((CheckBox) view).isChecked();
if(checked){
if (!addCheckBoxValue.contains(selectedCbValue))
addCheckBoxValue.add(selectedCbValue);
}else{
if (addCheckBoxValue.contains(selectedCbValue))
addCheckBoxValue.remove(selectedCbValue);
}
}
});
rowView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//if i click on textView, it works but when i click on checkbox here, it doesnt work why?? So i have clicklistener in checkbox abov
}
});
return rowView;
}
Create Following method in your CustomAdapter class:
public ArrayList<String> getCheckBoxValue(){
return addCheckBoxValue;
}
And in your ListActivity. Change your activity code like this:
private CustomAdapter listAdapter; // declare this before on create
Now where you are setting adapter in your on create write this code:
listAdapter = new CustomAdapter(this, nameList, imageList)
// set Adapter like this:
listView.setAdapter(listAdapter);
your button on click code should be like this:
compareBtn.setOnClickListener(new View.OnClickListener()
{ #Override
public void onClick(View view) {
//I need to have addCheckBoxValue arraylist from adapter here
listAdapter.getCheckBoxValue(); // do whatever you want to do here
}
}
Happy Coding!!!
I suggest you make boolean array for checkbox and maintain it like this way,this worked for me
public class CustomAdapter extends BaseAdapter {
private final LayoutInflater inflater;
private final Context context;
private List<ModelPooja> listData;
public CustomAdapter(Context mainActivity, List<ModelPooja> listData) {
context = mainActivity;
this.listData = listData;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return listData.size();
}
#Override
public Object getItem(int position) {
return listData.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.list_item_poojaselection, null);
holder.tv = (TextView) convertView.findViewById(R.id.list_item_poojaname);
holder.checks = (CheckBox) convertView.findViewById(R.id.list_item_poojacheck);
convertView.setTag(holder);
}else {
holder = (ViewHolder) convertView.getTag();
}
holder.checks.setOnCheckedChangeListener(null);
holder.checks.setFocusable(false);
if (listData.get(position).isselected) {
holder.checks.setChecked(true);
} else {
holder.checks.setChecked(false);
}
holder.checks.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton cb, boolean b) {
if (checkMaxLimit()) {
if (listData.get(position).isselected && b) {
holder.checks.setChecked(false);
listData.get(position).isselected = false;
} else {
holder.checks.setChecked(false);
listData.get(position).isselected = false;
Toast.makeText(context, "Max limit reached", Toast.LENGTH_SHORT).show();
}
} else {
if (b) {
listData.get(position).isselected = true;
} else {
listData.get(position).isselected = false;
}
}
}
});
holder.tv.setText(listData.get(position).getPOOJA_LISTING_NAME());
return convertView;
}
public boolean checkMaxLimit() {
int countermax = 0;
for(ModelPooja item : listData){
if(item.isselected){
countermax++;
}
}
return countermax >= 5;

I want to mark radio button true in listview onItemClick so what I am doing is
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
LinearLayout item_view = (LinearLayout) view;
final RadioButton itemcheck = (RadioButton) item_view
.findViewById(R.id.listview_radiobutton);
if (itemcheck.isChecked()) {
itemcheck.setChecked(true);
} else {
itemcheck.setChecked(false);
}
itemcheck.setChecked(true);
}
My listview
<ListView
android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_marginLeft="#dimen/view_margin_15"
android:layout_marginRight="#dimen/view_margin_15"
android:layout_marginTop="#dimen/view_margin_20"
android:layout_weight="1"
android:choiceMode="singleChoice"
android:divider="#drawable/list_divider"
android:dividerHeight="#dimen/padding_2"
android:fastScrollEnabled="true"
android:footerDividersEnabled="true"
android:listSelector="#null"
android:scrollbars="none"
android:textFilterEnabled="true"
android:textStyle="normal" />
Edit:--
My Adapter code :--
public class Adapter extends ArrayAdapter<Details> {
private Context mContext;
private List<Details> transList;
private LayoutInflater infalInflater;
private OnCheckedRadioButon onCheckedRadioButon;
private Typeface mTypeface, mEditTypeface, mPasswdTypeface;
private int mSelectedPosition = -1;
private RadioButton mSelectedRB;
private PromoViewHolder viewHolder;
public Adapter(Context context, List<Details> mtransList, OnCheckedRadioButon onCheckedRadioButon) {
super(context, R.layout.dialog_listview, mtransList);
this.mContext = context;
this.transList = mtransList;
this.onCheckedRadioButon = onCheckedRadioButon;
this.infalInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
try {
viewHolder = null;
row = infalInflater.inflate(R.layout.dialog_listview_code, parent, false);
viewHolder = new ViewHolder();
viewHolder.radiobutton = (RadioButton) row.findViewById(R.id.radiobutton);
viewHolder.listview_name = (TextView) row.findViewById(R.id.listview_name);
setValueText(viewHolder, position);
viewHolder.radiobutton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean checked) {
if (checked) {
onCheckedRadioButon.onCheckedButton(transList.get(position));
}
}
});
viewHolder.radiobutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (position != mSelectedPosition && mSelectedRB != null) {
mSelectedRB.setChecked(false);
}
mSelectedPosition = position;
mSelectedRB = (RadioButton) v;
}
});
if (mSelectedPosition != position) {
viewHolder.radiobutton.setChecked(false);
} else {
viewHolder.radiobutton.setChecked(true);
if (mSelectedRB != null && viewHolder.radiobutton != mSelectedRB) {
mSelectedRB = viewHolder.radiobutton;
}
}
row.setTag(viewHolder);
} catch (Exception e) {
e.printStackTrace();
}
return row;
}
private void setValueText(ViewHolder viewHolder, final int position) {
viewHolder.listview_name.setText(transList.get(position).getName());
}
public interface OnCheckedRadioButon {
void onCheckedButton(Details pr);
}
class ViewHolder {
RadioButton radiobutton;
TextView listview_name;
}
}
It is working but if I click on another position of the listview then the previous radiobutton position is not unchecked.I want to uncheck all the previous ones and mark only one at a time.
Any help will be appreciated.
Use POJO classes (Setter or Getter) to manage this type of condition. Use boolean variable in that class and change its values according to the position true or false.
POJO Class Like :
public class CheckListSource {
public boolean isSelected;
public boolean isSelected() {
return isSelected;
}
public void setSelected(boolean selected) {
isSelected = selected;
}
}
In your adapter :
private ArrayList<CheckListSource > itemsData;
public ChildListAdapter(Activity activity, ArrayList<ChildListResponse> baseResponse) {
this.itemsData = baseResponse;
this.activity = activity;
}
In BindViewHolder Like :
viewHolder.checkParentView.setTag(itemsData.get(position));
viewHolder.checkParentView.setOnClickListener(checkedListener);
private View.OnClickListener checkedListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
CheckListSource childListResponse = (CheckListSource ) v.getTag();
if (childListResponse.isSelected())
childListResponse.setSelected(false);
else
childListResponse.setSelected(true);
notifyDataSetChanged();
}
};
Use a boolean array in your Activity. Each boolean value corresponds to a RadioButton.
If a RadioButton is checked, set its boolean value to true, and set all other boolean values in the array to false.
In the getView() of your Adapter, call your_radio_button.setChecked(your_boolean_array[position]).
Once the boolean array is modified, call your_adapter.notifyDataSetChanged().
Checkout this it works for me..
public class ProgramAdapter extends ArrayAdapter<KeyInformation> {
private final String TAG = "ProgramAdapter";
private List<KeyInformation> mList;
private Context mContext;
private LayoutInflater mInflater;
private int mSelectedPosition = -1;
private RadioButton mSelectedRB;
private String mUserApllication = "";
public ProgramAdapter(Context context, List<KeyInformation> objects) {
super(context, R.layout.program_item, objects);

}

holder.mImageView = (ImageView) convertView.findViewById(R.id.icon);
holder.mTextView = (TextView) convertView.findViewById(R.id.text);
holder.mSeparator = (TextView) convertView.findViewById(R.id.title_separator);
holder.mRadioButton = (RadioButton) convertView.findViewById(R.id.radioBtn);
convertView.setTag(holder);
} else {

}
holder.mRadioButton.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View view) {
if(position != mSelectedPosition && mSelectedRB != null){
mSelectedRB.setChecked(false);
}
mUserApllication ="";
mSelectedPosition = position;
mSelectedRB = (RadioButton) view;
}
});
String userApp = mList.get(position).packageName;
if(mUserApllication.equals(userApp)) {
mSelectedPosition = position;
}
if (mSelectedPosition != position) {
holder.mRadioButton.setChecked(false);
} else {
holder.mRadioButton.setChecked(true);
mSelectedRB = holder.mRadioButton;
}
holder.mImageView.setImageDrawable(mList.get(position).icon);
holder.mTextView.setText(mList.get(position).lable);
if (position == 5) {
holder.mSeparator.setVisibility(View.VISIBLE);
} else {
holder.mSeparator.setVisibility(View.GONE);
}
return convertView;
}
public int getmSelectedPosition () {
return mSelectedPosition;
}
private static class ViewHolder {

}
}
