list view inside list View in android

I am Using a list view inside a listview and both listview share same list item.
It is working fine but if height of the item increases in inside list view it doesn't wrap the content and put a scrollview which is not as per requirement.
Please see the codes below
activity_main.xml

please see the highlighted area of image listview height is not proper to wrap the content
any help would be appericiated

The problem is you can't get the scroll of both listview at a time. if you what you both at the same time. you need to create a custom list view try something like this instead of your list view (inside list).
public class NonScrollListView extends ListView {
public NonScrollListView(Context context) {
super(context);
}
public NonScrollListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
}

Their are some points you need to fix.
Give a proper height to your ListView so that it can scroll within that boundry, wrap_content is never recommended for ListView. So better to put some height to your ListView.
Listview inside a ListView will not give the user experience good. Try a work around or better to Use RecyclerView. RecyclerView is better in performance in case of nested list.
Hope it will help :)

How to use buttons from different xml files in one class

I have a listview with multiple items and one button to start a new activity. I'm getting Null Pointer Exception when I run my app. How and where shoud I set the OnClickListener to run properly?
Also, how can I pass with Intent the arraylist named listaIngrediente?
Here is my code
main_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context="com.example.radu.fridgecheck.MainActivity"
android:orientation="vertical">
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
</ListView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/find_recipies"
android:id="#+id/find"
android:layout_weight="0"/>
</LinearLayout>
list_item.xml

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/checkBox"
android:layout_alignBottom="#+id/checkBox"
android:layout_toRightOf="#+id/checkBox"
android:text="TextView" />
</RelativeLayout>
Adapter
public class Adapter extends ArrayAdapter<Ingredient> {
public LayoutInflater inflater;
public ArrayList<Ingredient> listaIngrediente;
ArrayList<String> ingredienteDisponibile;
private Activity activity;
public Adapter(Activity activity, int textResourceId, ArrayList<Ingredient> ingrediente) {
super(activity, textResourceId, ingrediente);
this.activity=activity;
this.listaIngrediente=ingrediente;
try {
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
} catch (Exception e) {
e.printStackTrace();
}
}
public int getCount() {
return listaIngrediente.size();
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (convertView == null) {
v = inflater.inflate(R.layout.list_item, null);
}
final Ingredient ingredients = getItem(position);
final TextView display_ingredients = (TextView) v.findViewById(R.id.name);
display_ingredients.setText(ingredients.getNameI());
final CheckBox checkBox = (CheckBox) v.findViewById(R.id.checkBox);
ListView listView = (ListView) v.findViewById(R.id.listView1);
Button button = (Button) v.findViewById(R.id.button);
listView.addFooterView(button);
Button find = (Button) v.findViewById(R.id.find);
find.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent i = new Intent(getContext(), ShowRecipes.class);
Bundle args = new Bundle(); /// nu reusesc sa transfer obiectele
args.putSerializable("ARRAYLIST",listaIngrediente);
i.putExtra("BUNDLE",args);
activity.startActivity(i);
}
});
v.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(!ingredients.isSelected()) {
checkBox.setChecked(true);
ingredients.setSelected(true);
}
else{
checkBox.setChecked(false);
ingredients.setSelected(false);
}
}
});
return v;
}
}

You have to write that in MainActivity class, because your button is in main_activity.xml
In MainActivity, write this method
public void showRecipes(View view) {
Intent i = new Intent(getContext(), ShowRecipes.class);
Bundle args = new Bundle(); /// nu reusesc sa transfer obiectele
args.putSerializable("ARRAYLIST",listaIngrediente);
i.putExtra("BUNDLE",args);
startActivity(i);
}
In Xml add onClick
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/find_recipies"
android:id="#+id/find"
android:onClick="showRecipes"
/>`

setOnItemClickListener is not working for ArrayAdapter<ImageView>

When i try to click on items in the list it doesnt go through the onItemClick method.

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.

Android ListView based in custom BaseAdapter is not shown in my code

I've working on ListView with a custom BaseAdapter which I've watched on the Slidenerd tutorial series here:(It's not important to watch to understand my question)
http://www.youtube.com/watch?v=_l9e2t4fcfM&list=PLonJJ3BVjZW6hYgvtkaWvwAVvOFB7fkLa&index=91
After running the code on the virtual device there is no error but not ListView too.
Is it possible to tell me what's the problem of my code?
public class List extends Activity {
ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
lv = (ListView) findViewById(R.id.listView);
lv.setAdapter(new EhsanAdapter(this));
}

getMenuInflater().inflate(R.menu.list, menu);
return true;
}
}
class SingleRow{
String title;
String description;
int image;
public SingleRow(String title,String description,int image) {
this.title = title;
this.description=description;
this.image=image;
}
}
class EhsanAdapter extends BaseAdapter{
ArrayList<SingleRow> list;
Context context;
public EhsanAdapter(Context c) {
list = new ArrayList<SingleRow>();
context = c;
Resources res = c.getResources();
String[] titles = res.getStringArray(R.array.titles);
String[] descriptions = res.getStringArray(R.array.descriptions);
int[] images = {R.drawable.image1,R.drawable.image2,R.drawable.image3,R.drawable.image4,R.drawable.image5};
for(int i=0;i<10;i++){
list.add(new SingleRow(titles[i], descriptions[i], images[i]));
}
}
#Override

return list.size();
}
#Override

SingleRow temp = list.get(i);
title.setText(temp.title);
description.setText(temp.description);
image.setImageResource(temp.image);
return row;
}
}
The layout of activity:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Remove the line LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); from getView() method and instead add it in the constructor of EhsanAdapter class.

I see different issues:
The layout of single row contains a relative layout which the android:layout_height="match_parent" should be android:layout_height="wrap_content"
Then inside the Adapter you are neither recycling the views nor using the ViewHolder pattern:
http://developer.android.com/training/improving-layouts/smooth-scrolling.html
About ViewHolder pattern implementation optimisation in ListView
http://www.jmanzano.es/blog/?p=166
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
if (view == null){ //The row view is not created, let's do it:
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.single_row, viewGroup,false);
TextView title = (TextView) row.findViewById(R.id.txtTitle);
TextView description = (TextView) row.findViewById(R.id.txtDescription);
ImageView image = (ImageView) row.findViewById(R.id.imgPic);
// Here we add the title, description and image inside the ViewHolder
....
}else{
//With the View holder pattern we get the views inside the row view to fill it later
....
}
// Now we get the SingleRow and we fill it using the ViewHolder pattern
SingleRow temp = list.get(i);
....
return row;
}

You only have 5 images and you wrote i<10 you should've wrote i<5 the amount of "titles" and "descriptions" and "images" must be the same.
for(int i=0;i<5;i++){
list.add(new SingleRow(titles[i], descriptions[i], images[i]));
}

UnsupportedOperationException in creating custom ListView in Android

i wanted to have a custom listView so I did this:
Created an Activity:
public class PRS_MainList_Act extends ListActivity {
MainListAdapter mladp;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_prs__main_list_);
ArrayList<MainMenuItem> menuItems = new ArrayList<MainMenuItem>();
menuItems.add(new MainMenuItem(getResources().getString(R.string.main_list_connectivity), getResources().getString(R.string.main_list_connectivityDesc)));
this.mladp = new MainListAdapter(this, R.layout.man_list_item, R.id.textView1, menuItems);
setListAdapter(mladp);
}
}
Create a class for menu items:
public class MainMenuItem {
private String itemText;

Custom array adapter:
public class MainListAdapter extends ArrayAdapter<MainMenuItem> {
ArrayList<MainMenuItem> menuItems;
public MainListAdapter(Context context, int resource,
int textViewResourceId, ArrayList<MainMenuItem> menuItems) {
super(context, resource, textViewResourceId, menuItems);
this.menuItems = menuItems;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (convertView == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.man_list_item, parent);
}
MainMenuItem it = menuItems.get(position);
if (it != null) {
TextView titleTV = (TextView) view.findViewById(R.id.textView1);
TextView descriptionTV = (TextView) view.findViewById(R.id.textView2);
ImageView iconIV = (ImageView)view.findViewById(R.id.imageView1);
if (titleTV != null) {
titleTV.setText(it.getItemText());
}
if(descriptionTV != null){
descriptionTV.setText(it.getItemDescription());
}
if(iconIV != null){
if(it.getItemText().equals(getContext().getResources().getString(R.string.main_list_connectivity)))
iconIV.setImageResource(R.drawable.network_connections);
}
}
return view;
}
}
and here are my activity layout and item layout:
<LinearLayout 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=".PRS_MainList_Act" >
<ListView android:id="#android:id/list"
android:layout_height="match_parent"
android:layout_width="match_parent"/>
</LinearLayout>
Item Layout:
<?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"

I got this error saying: java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView
Thanks in advance for your help.

You can't use this version of the inflate method:
view = vi.inflate(R.layout.man_list_item, parent);
because this will add the inflated View to the parent, which isn't allowed in a ListView. Instead use this version:
view = vi.inflate(R.layout.man_list_item, parent, false);
which will inflate the view but will not add it to the parent. This version is important because it will provide the proper LayoutParams for your inflated view.
