I have a custom listview, inside of which there is another one. And the one that is nested will not scroll. Perhaps you need to register something in the parent setOnTouchListener? I don't have anything like that in getView.

I have a view in an activity as below .I want to set Margin to the view.But i used Viewgroup.LayoutParams but it doesn't change the view of the row.Below i have given custom adapter which takes data from firstpagerowitems.xml.I have given the java code for adapter .I tried doing android:layout_marginbottom="10dp" for firstpagerowitems.xml and firstpage.xml but it doesnt work.
class MyAdapter extends ArrayAdapter<String> {
Context context;
ArrayList<String> rTitle;
ArrayList<String> rDescription;
ArrayList<String> rImgs;
MyAdapter (Context c, ArrayList<String> title,ArrayList<String> description,ArrayList<String> imgs) {
super(c, R.layout.firstpagerowitems, R.id.textView1, title);
this.context = c;
this.rTitle = title;
this.rDescription = description;
this.rImgs = imgs;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
LayoutInflater layoutInflater = (LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = layoutInflater.inflate(R.layout.firstpagerowitems, parent, false);
TextView images = row.findViewById(R.id.textView3);
TextView myTitle = row.findViewById(R.id.textView1);
TextView myDescription = row.findViewById(R.id.textView2);
Log.d("entered last","yes");
Log.d("postion", String.valueOf(position));
Log.d("rimgs", String.valueOf(rImgs));
Log.d("desc", String.valueOf(rDescription));
Log.d("title", String.valueOf(rTitle));
// now set our resources on views
images.setText(rImgs.get(position));
myTitle.setText(rTitle.get(position));
myDescription.setText(rDescription.get(position));
Random random=new Random();
int trp=random.nextInt(16);
Log.d("enteredcolor",mycolors[trp]);

I have a custom layout for the list's cells where you have a checkbox and 3 text elements. I found on Stackoverflow that I should add android:descendantFocusability = "blocksDescendants" on my LinearLayout where the list is but it doesn't change anything.
Here is my XML for the page with the list :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
android:background="#color/colorPrimary"
android:clickable="true"
android:focusable="true"
android:orientation="vertical"
tools:context=".ui.home.AperoDetailFragment"
android:descendantFocusability="blocksDescendants">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:orientation="horizontal">
<TextView
android:id="#+id/name_apero"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingHorizontal="10dp"
android:gravity="left"
android:textSize="18sp" />
<TextView
android:id="#+id/date_apero"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingHorizontal="10dp"
android:ems="10"
android:gravity="right"
android:textSize="18sp" />
</LinearLayout>
<View

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:orientation="horizontal">
<TextView
android:id="#+id/txtView_shopping_list"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="1"
android:paddingHorizontal="10dp"
android:text="#string/shopping_list_title" />
<Button
android:id="#+id/btn_add_ingredients"

</LinearLayout>
<ListView
android:id="#+id/list_ingredient"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal" />
</LinearLayout>
then in my Java code I set the listener like this :
#Override
public View onCreateView(#NonNull final LayoutInflater inflater,
final ViewGroup container, Bundle savedInstanceState) {
root = inflater.inflate(R.layout.fragment_detail_apero, container, false);
final TextView name = (TextView) root.findViewById(R.id.name_apero);
name.setText(detailApero.name);
TextView date = (TextView) root.findViewById(R.id.date_apero);
date.setText(detailApero.date);
// some code that aren't useful right now
//-------------- List of ingredients for the detailed apero
final ListView list_ingredient = (ListView) root.findViewById(R.id.list_ingredient);
LaperoDatabase db = Room.databaseBuilder(root.getContext(),
LaperoDatabase.class, "lapero_db").allowMainThreadQueries().build();
IngredientDao dbIngredient = db.getIngredientDao();
//#TODO control if we get the right ingredients
ArrayList<Ingredient> ingredient_of_this_apero = (ArrayList<Ingredient>) dbIngredient.getIngredientsFromApero(detailApero.aid);
IngredientAdapter adapter = new IngredientAdapter(root.getContext(), R.layout.ingredient_cell_layout, ingredient_of_this_apero);
list_ingredient.setAdapter(adapter);
list_ingredient.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View v, int position, long id) {
Ingredient selected_ingredient = (Ingredient) adapter.getItemAtPosition(position);
Log.e("test","okasodkdaso");
}
});
return root;
}
I also tried using a OnItemLongClickListener but it also does nothing. How can I put a listener for the list items ?
I have an ExpandableListView in my app. I want to make the child layout a bit narrower than the group header and also keep it centered. Due to some visual effects i must set layout params from code however i can't seem to find the best solutions for this tried changing layout width from xml with no luck. Any advice will be helpful.
Thanks

I'd put all Views in one single ConstraintLayout. By attaching the background to the parent left and right, the View is default centered. By adding margins left and right, you achieve the View being smaller.
Like in this example:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageView2"
android:layout_width="0dp"
android:layout_height="?attr/actionBarSize"
android:layout_marginBottom="8dp"
android:layout_marginEnd="16dp"
android:layout_marginStart="16dp"
android:layout_marginTop="8dp"
android:background="#android:color/darker_gray"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<CheckBox
android:id="#+id/checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:buttonTint="#android:color/background_light"
android:text="CheckBox"
android:textColor="#android:color/background_light"
app:layout_constraintBottom_toBottomOf="#+id/imageView2"
app:layout_constraintStart_toStartOf="#+id/imageView2"
app:layout_constraintTop_toTopOf="#+id/imageView2" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginStart="24dp"
android:layout_marginTop="8dp"
android:text="Stuff"
android:textColor="#android:color/background_light"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toEndOf="#+id/checkBox"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
which looks like this:
the
android:layout_width="0dp"
actually means the view will be stretched to match the constraints. A bit like "match_parent", but within the bounds you set via its constraints.
Play around with the ConstraintLayout a bit. Once you get the hang of it, you will not want to miss it anymore :)

java code used to show snake bar
private CoordinatorLayout _CoordinatorLayout;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.compition, null);
_CoordinatorLayout = (CoordinatorLayout) v.findViewById(R.id.fullview);
}
Snackbar.make(_CoordinatorLayout , message , Snackbar.LENGTH_LONG).show();
here is screen shot
what I miss ??
The documentation here says:
Snackbars appear above all other elements on screen and only one can
be displayed at a time.
So, Snackbar will cover your view, just like a Toast.
I have a listview with some texts in it like this
and I want to expand each item to like this
I have seen this answer(How can I make a cell in a ListView in Android expand and contract vertically when it's touched?), here it doesn't changes to a new view, but just changes the height.
UPDATE:list_item.xml

You can use ExpandableListView:
You define a custom layout for the child (the details when you click on the row)
You define an public class ExpandableAdapter extends BaseExpandableListAdapter
Override the method
public View getChildView(int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
....
}
where you implement your detail layout (child layout).
Override the method
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
...
}
where you implement the layout like the ListView.
Set the custom adapter in your ExpandableListView instance
If you want to have more info give a look at my post here http://www.survivingwithandroid.com/2013/01/android-expandablelistview-baseexpandablelistadapter.html
Have you tried ExpandableListView with only one child view for each group view? then you can expand and collapse rows as you want.
