I have made a custom ArrayAdapter and tried to add the another TextView "Breed" of the animals, but when i execute the program , its not showing the Breed. Where am i doing wrong ? I am scratching my head since long. please help where is the mistake ?
MainActivity.Java
public class MainActivity extends AppCompatActivity {
ListView simpleList;
ArrayList<Item> animalList=new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
simpleList = (ListView) findViewById(R.id.simpleListView);
animalList.add(new Item("Lion",R.drawable.lion,"Khatarnak"));
animalList.add(new Item("Tiger",R.drawable.tiger,"Fudu"));
animalList.add(new Item("Monkey",R.drawable.monkey,"Lallu"));
animalList.add(new Item("Elephant",R.drawable.elephant,"Jabardast"));
animalList.add(new Item("Dog",R.drawable.dog,"ItemDog"));
animalList.add(new Item("Cat",R.drawable.cat,"MeeMee"));
MyAdapter myAdapter=new MyAdapter(this,R.layout.list_view_items,animalList);
simpleList.setAdapter(myAdapter);
}
}
MyAdapter.Java
public class MyAdapter extends ArrayAdapter<Item> {
ArrayList<Item> animalList = new ArrayList<>();
public MyAdapter(Context context, int textViewResourceId, ArrayList<Item> objects) {
super(context, textViewResourceId, objects);
animalList = objects;
}
#Override
public int getCount() {
return super.getCount();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.list_view_items, null);
TextView textView = (TextView) v.findViewById(R.id.textView);
ImageView imageView = (ImageView) v.findViewById(R.id.imageView);
TextView breedView = (TextView)v.findViewById(R.id.breed);
textView.setText(animalList.get(position).getAnimalName());
imageView.setImageResource(animalList.get(position).getAnimalImage());
breedView.setText(animalList.get(position).getBreed());
return v;
}
}
Item.Java
public class Item {
String animalName;
int animalImage;
String breedName;
public String getBreed() {
return breedName;
}
public void setBreed(String breed) {
this.breedName = breedName;
}
public Item(String animalName,int animalImage,String breedName)
{
this.animalImage=animalImage;
this.animalName=animalName;
this.breedName = breedName;
}
public String getAnimalName()
{
return animalName;
}
public int getAnimalImage()
{
return animalImage;
}
}

This is most likely a problem with the linear layout for each item. The orientation is horizontal, which lays each view one after the other horizontally. The problem is that the text view for the animal type has a width of fill_parent leaving no space for the breed view. If you change it to wrap_content it'll probably work for some of the cases, but might not work with everything.
In any case I think this is a problem with the views' positions and sizes. Try and move them around. Perhaps even a simple change would be placing them vertically:
<?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:orientation="horizontal">
<ImageView
android:id="#+id/imageView"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="5dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Demo"

<TextView
android:id="#+id/breed"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Breed"
android:textColor="#000" />
</LinearLayout>
</LinearLayout>
There's perhaps a more efficient way of doing this, but this is just an example. The inner linear layout places one text view on to of the other.
PS: your getCount method is not really doing anything. You can remove it.
replace your layout with my code your issue will resolve.
<?xml version="1.0" encoding="utf-8"?>

I am trying to create an activity where the user can create some recipe and input the ingredients. every time the user enters an ingredient, it should be added to a listview. The issue I am having here is that the first input is the only one that is added to the listview not the others.
Here is the layout script:
<?xml version="1.0" encoding="utf-8"?><ScrollView

android:orientation="vertical">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="226dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="8dp"
android:orientation="vertical">

And the logic behind it :
public class AddActivity extends AppCompatActivity {
private ListView added_ing;
private IngredientAdapter adapter;
private ArrayList<String> ingredients = new ArrayList<String>();
private EditText new_ing;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add);
adapter = new IngredientAdapter(AddActivity.this,ingredients);
added_ing = findViewById(R.id.ingredient_list);
added_ing.setAdapter(adapter);
new_ing = findViewById(R.id.new_ing);
ImageView add_ingredien = findViewById(R.id.add_ingredient_btn);
add_ingredien.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ingredients.add(new_ing.getText().toString());
Toast.makeText(AddActivity.this, new_ing.getText().toString(), Toast.LENGTH_SHORT).show();
adapter.notifyDataSetChanged();
}
});
}
public class IngredientAdapter extends ArrayAdapter<String> {
ArrayList<String> mNewIngredients;
public IngredientAdapter(Context context, ArrayList<String> objects) {
super(context, 0, objects);
mNewIngredients = objects;
}
public String getItem(int position) {
return mNewIngredients.get(position).toString();
}
public View getView(int position, View convertView, ViewGroup parent) {
String item = getItem(position);
if(convertView==null)
convertView = LayoutInflater.from(getContext()).inflate(R.layout.ingredient,parent,false);
TextView recipeName= convertView.findViewById(R.id.new_added_ingredient);
recipeName.setText(item);
return convertView;
}
}
}
Try to scroll down your list view, maybe in your item's layout, you set the layout_height = match_parent so you do not see the other inputs.
You need to add android:fillViewport="true" to your ScrollView
Also change all child LinearLayout height to wrap_content instead of match_parent
Try this
<?xml version="1.0" encoding="utf-8"?><ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

In your implementation of IngredientAdapter, you are using your own ArrayList mNewIngredients for the data instead of the collection in the ArrayAdapter. When you add new data into ingredients, it is not added to the adapter.
To make use of the collection implemented in ArrayAdapter for simplicity. The following is an example, with a view holder so that views can be reused.
public class IngredientAdapter extends ArrayAdapter<String> {
public IngredientAdapter(Context context, ArrayList<String> objects) {
super(context, 0, objects);
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if(convertView==null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.ingredient, parent, false);
holder = new ViewHolder();
holder.recipeName = convertView.findViewById(R.id.new_added_ingredient);
convertView.Tag = holder;
} else {
holder = (ViewHolder)convertView.Tag;
}
String item = getItem(position);
holder.recipeName.setText(item);
return convertView;
}
}
public class ViewHolder {
public TextView recipeName;
}
The data in the adapter is now backed by the internal collection. And in the activity, you should add the new data into adapter directly.
public class AddActivity extends AppCompatActivity {
private ListView added_ing;
private IngredientAdapter adapter;
// keep this if you need it for something else
// private ArrayList<String> ingredients = new ArrayList<String>();
private EditText new_ing;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add);
adapter = new IngredientAdapter(AddActivity.this,ingredients);
added_ing = findViewById(R.id.ingredient_list);
added_ing.setAdapter(adapter);
new_ing = findViewById(R.id.new_ing);
ImageView add_ingredien = findViewById(R.id.add_ingredient_btn);
add_ingredien.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// keep this if you need it for something else
// ingredients.add(new_ing.getText().toString());
// to add adata into the adapter
adapter.Add(new_ing.getText().toString());
Toast.makeText(AddActivity.this, new_ing.getText().toString(), Toast.LENGTH_SHORT).show();
adapter.notifyDataSetChanged();
}
});
}
}
I have a problem. I got an Stackoverflow Error. I tried reduced the Layout and so on. But nothing worked.
I have a view pager and in the fragments are recyclerviews 4 times. (one in each). The inflater Code
View root = inflater.inflate(R.layout.content_main, container, false);
One Layout in Fragment for example:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.RecyclerView
android:id="#+id/list_view"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:layout_marginTop="15dp"
android:layout_height="wrap_content" />
And this is the Layout for the ReclerView Item
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
android:id="#+id/cv"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_margin="20dp"
android:clickable="true"
android:background="?attr/selectableItemBackground"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center|left"
android:padding="10dp"
android:clickable="true"
android:background="?attr/selectableItemBackground"
>
<ImageView
android:id="#+id/album_cover"
android:layout_width="33dp"
android:layout_height="50dp"
android:layout_marginRight="16dp"
android:src="#drawable/ic_supervisor_account_black_24dp" />
<TextView
android:id="#+id/album_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Artistname"
android:textColor="#000000"
android:textSize="15sp" />
</LinearLayout>
</android.support.v7.widget.CardView>
One Layout has a Relative Layout but it works before I made some changes:
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cv"
android:layout_width="match_parent"

android:layout_margin="10dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:clickable="true"
android:longClickable="true"
android:background="?attr/selectableItemBackground"
>
<ImageView
android:id="#+id/album_cover"
android:layout_width="66dp"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginRight="16dp"
android:src="#drawable/spring_276014_640" />
<TextView
android:id="#+id/album_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/album_cover"
android:text="Albumtitel"
android:textColor="#000000"
android:textSize="20sp" />
<TextView
android:id="#+id/album_artist"
android:layout_width="wrap_content"
android:layout_marginTop="5dp"
android:layout_height="wrap_content"
android:layout_below="#+id/album_name"
android:layout_toRightOf="#+id/album_cover"
android:text="von Artist xy" />
</RelativeLayout>
</android.support.v7.widget.CardView>
Captureing View Table is not possible because app is going down before it changes the layout.
Bitmaps are scaled.
Here is my Adapter:
public class DefaultAdapter extends RecyclerView.Adapter<DefaultAdapter.SongViewHolder> {
private Context con;
private List<String> names;
boolean useplaylist;
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public static class SongViewHolder extends RecyclerView.ViewHolder {
CardView cv;
TextView title;
SongViewHolder(View itemView) {
super(itemView);
cv = (CardView)itemView.findViewById(R.id.cv);
title = (TextView)itemView.findViewById(R.id.album_name);
}
}
// Provide a suitable constructor (depends on the kind of dataset)
public DefaultAdapter(Context context,List<String> names,boolean playlist) {
con = context;
this.names = names;
useplaylist = playlist;
}
// Create new views (invoked by the layout manager)
#Override
public SongViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.playlist_item, viewGroup, false);
SongViewHolder pvh = new SongViewHolder(v);
return pvh;
}
#Override
public void onBindViewHolder(SongViewHolder personViewHolder, int i) {
personViewHolder.title.setText(names.get(i));
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
return names.size();
}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
}

Can somebody help me?
Problem solved.
I don't know where the Error was but maby it was an empty list or the ImageAssets wich I replaced with vector assets and activate the Libary in the Gradle.
For thoos who have the same problem in a viewpage: Deactivate all fragments and enable them single, to test where the error is.
I have a GridView which has a ViewFlipper in each tile. Each view in the ViewFlipper has a different size, but when the tile is flipped, both views are forced to the same size as the GridView column. What i've tried:

Managed to achieve the same grid-style layout with my intented ViewFlipper effect using a StaggeredGridLayoutManager and a RecyclerView.
In Main RelativeLayout contain ViewFlipper, you set height and width!
set them "wrap_content"
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
maybe worked.
good luck.
Update
Use this library:
https://github.com/etsy/AndroidStaggeredGrid
I have gone through this & this SO questions but unable to figure out why the first item of my list view is not visible. I have checked the size of arraylist and it's correct.
if there is 2 items then it shows only 1.
if there is 1 item then it shows 0.
listview file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

Change the ListView attribute layout_width and layout_height to Fill_Parent
it worked for me.
I was having the same issue because my ListView layout_width and layout_height was "match_constraint" and the toolbar was overlapping the first item. Just adjust the height of the ListView. It works for me.
I already read tons of similar questions, but I found no solution that fixed my problem, so please do not mark this as duplicate.
I have a ListFragment with a FrameLayout containing a ListView, populated through a custom ArrayListAdapter.
Each row of the list has three elements:
Checkbox, EditText and ImageButton.
My problem is that when I tap on an EditText to change the string it contains the keyboard shows up, but the focus immediately goes away and I'm not able to write.
Please note that I already have added to my Activity in the manifest file
android:windowSoftInputMode="adjustResize"
even the
android:descendantFocusability="afterDescendants"
android:descendantFocusability="beforeDescendants"
doesn't solve the problem.
Here is my XML code:
row_item.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/item_checkbox"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
/>
<EditText
android:id="#+id/item_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="60px"
android:text="Test text"
android:singleLine="true"
android:layout_toRightOf="#id/item_checkbox"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/item_important"
android:layout_toStartOf="#+id/item_important" />
<ImageButton
android:id="#+id/item_important"
android:layout_width="20dip"
android:layout_height="20dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:visibility="visible"
android:layout_marginLeft="10dp" />
</RelativeLayout>
fragment_list.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="8dp"
android:paddingRight="8dp"
>
<ListView android:id="#id/android:list"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</FrameLayout>
It would be great if you could suggest me some resource where to understand how focusability works in this case.
Thank you
UPDATE
I found out the problem is created by the keyboard showing up: I guess the view recycling is the reason why the EditText loses focus.
I solved my issue using the new RecyclerView class. It seems that was a problem of the ListView
Try this code
row_item.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<CheckBox
android:id="#+id/item_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:focusable="false"/>
<EditText
android:id="#+id/item_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/item_important"
android:layout_toRightOf="#id/item_checkbox"
android:layout_toStartOf="#+id/item_important"
android:minHeight="60px"
android:focusable="true"
android:singleLine="true" />
<ImageButton
android:id="#+id/item_important"
android:layout_width="20dip"
android:layout_height="20dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:visibility="visible" />

Did you set android:focusable="true" and android:focusableInTouchMode="true" on your EditText?
Also the android:windowSoftInputMode="adjustPan" in your AndroiManifest file.
