I am a beginner to android. I want to display a customized list view which contains a number. I customized my ListView size(android:layout_height="50dp"). But when I run the app it display the size largely which am not given. I don't know how to fix this problem. Please anyone help me.
activity_topic_list.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I want to fix the list cell height
FYI
You want to add HEIGHT for each Cell
Then
<?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"
android:background="#drawable/storylist">
<TextView
android:id="#+id/topictitle"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="#string/title"
android:textSize="12sp"
android:textStyle="bold"
android:textColor="#android:color/background_light" />
</RelativeLayout>
Note
Use TextView Size unit sp instead of pt .
Try below changes on your parent layout on titledesign.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/storylist">
and if you want that your list capture full width of device screen make change on layout_width like
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/storylist">
This should help you out..
ListAdapter listadp = lv_ancillaryservice.getAdapter();
if (listadp != null) {
int totalHeight = 0;
for (int i = 0; i < listadp.getCount(); i++) {
View listItem = listadp.getView(i, null, lv_ancillaryservice);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = lv_ancillaryservice.getLayoutParams();
params.height = totalHeight + (lv_ancillaryservice.getDividerHeight() * (listadp.getCount() - 1));
lv_ancillaryservice.setLayoutParams(params);
lv_ancillaryservice.requestLayout();
Create the List view as
activity_word.xml
<?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">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#000000"
android:padding="5dp"
android:textSize="25dp"
android:gravity="center_horizontal|center_vertical"
android:text="Text"
android:id="#+id/text_list_view" />
</LinearLayout>
create another xml file and create a text view in it
listitem.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="match_parent">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:id="#+id/listView"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"/>
</RelativeLayout>
in the Toplist java class add this as setContentView
setContentView(R.layout.activity_word);

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 ?

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"
android:textColor="#000" />
<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.

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:
Googled
Set android:measureAllChildren to false on ViewFlipper(only works with ListView)
Left android:columnWidth unspecified
Made ViewFlipper root tag in grid tile layout file
grid_item.xml:

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 implemented my custom list but when I click an element of my list a Toast message should be displayed. It looks like that the setOnItemClickListener does not work.
Here there is the code of of my fragment layout in which there is my ListView
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff">
<ListView
android:id="#+id/listSearch"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false"
android:paddingStart="15dp"
android:paddingEnd="15dp"
android:focusable="false"/>
</LinearLayout>
here there is the structure of my list (each single line)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<ImageView
android:id="#+id/imageContact"
android:layout_width="60dp"
android:layout_height="60dp"
android:padding="5dp"
android:focusable="false"/>
<TextView
android:id="#+id/nameSurnameContact"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_marginLeft="10dp"
android:layout_marginTop="5dp"
android:padding="2dp"
android:textColor="#33CC33"
android:focusable="false"/>
<TextView
android:id="#+id/idContact"
android:layout_width="match_parent"
android:layout_height="0dp"
android:visibility="invisible"
android:focusable="false"
/>
</LinearLayout>
</LinearLayout>
and here there is the mothod of my fragment that creates the layout and populate the list
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedBundle) {
View firstAccessView;
if(savedBundle==null) {
firstAccessView = inflater.inflate(R.layout.search_fragment_layout, null);
for(int i=0; i<8; i++){
Contact c = new Contact(idContact[i], nameSurname[i], facebookId[i], timeStamp[i]);
this.rows.add(c);
}
adapter = new SearchListAdapter(getActivity(), this.rows);
list = (ListView) firstAccessView.findViewById(R.id.listSearch);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getActivity().getApplicationContext(), "item selected", Toast.LENGTH_SHORT).show();
}
});
list.setOnScrollListener(this);
}else{
firstAccessView = getView();
}
return firstAccessView;
}
is there something that I missed in the xml files of in the Fragment file?
Remove android:focusable="false" from ListView.
android:focusable="false"
Remove this line from your listview xml file
I want my rows of gridview be placed in center(horizontally)
I have two columns with same width.
Each item will be placed in center of the respective column.
I tried to follow other answers. None of them worked.
So frustrating when simple layout doesn't work as intended...
<?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="match_parent"
>
<GridView
android:id="#+id/gridView_album"
android:numColumns="2"
android:stretchMode="columnmWidth"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:gravity="center"
android:layout_gravity="center"
>
</GridView>
</RelativeLayout>
row's xml is
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:orientation="vertical" >
<TextView
android:id="#+id/textView_albumTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="album title" />
</LinearLayout>
<ImageView
android:id="#+id/imageView1"
android:layout_width="105dp"
android:layout_height="100dp"
android:src="#drawable/abs__ab_share_pack_holo_light" />
</LinearLayout>
This is how I've done it
Your gridView.xml
<?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"
android:orientation="vertical" >
<GridView
android:id="#+id/home_grid"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:listSelector="#drawable/holo_blue_color"
android:numColumns="2"
android:layout_marginTop="10dip"
android:verticalSpacing="10dip" >
</GridView>
</LinearLayout>
Now Your gridView Items xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="3dp"
android:textColor="#000000"
android:textSize="16dip"
android:textStyle="normal" >
</TextView>
Now I made an adapter class which set the image and text
class MyGridAdapter extends BaseAdapter {
ArrayList<String> name;
ArrayList<Integer> resId;
LayoutInflater inflater;
public MyGridAdapter(Context context, ArrayList<String> name,
ArrayList<Integer> resId) {
this.name = name;
this.resId = resId;
inflater = LayoutInflater.from(context);
}
public int getCount() {
// TODO Auto-generated method stub
return name.size();
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return resId.get(arg0);
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
convertView = inflater.inflate(R.layout.grid_textview, null);
TextView tv = (TextView) convertView.findViewById(R.id.textview);
tv.setText(name.get(position));
tv.setCompoundDrawablesWithIntrinsicBounds(0, resId.get(position),
0, 0);
return convertView;
}
}
You do not need to include ImageView. You can align the image around TextView using setCompoundDrawablesWithIntrinsicBounds
Now just two line in your activity
final MyGridAdapter adapter = new MyGridAdapter(this, name, resId);
gridView.setAdapter(adapter);
I am having problems with ListView on android. I have an Activity with an EditText view and a button. The idea is user should enter some info in the EditText field, touch the Search button which retrieves a list from a web service that it is displayed in the same activity below the EditText and the Button. Everything fine, I got the data from Internet but items weren't displaying. I was using the notifyDataSetChanged(). After a couple of hours with no success, I decided trying to put some items manually and it turns out that again nothing was displayed, hence I think I am doing something wrong when I am trying to set the listview and the adapter. So here is the code..
the xml of the activity activity_search.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp">
<EditText
android:id="#+id/edit_search"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5"
android:inputType="text"
android:hint="Enter info"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/button_search"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#android:drawable/ic_menu_search"
android:contentDescription="Search"
android:ems="10" />
</LinearLayout>
<ListView
android:id="#+id/listview_items"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false" />
The XML of the item row.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_margin="5dp">
<TextView
android:id="#+id/row_code"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Common_TextContent"
android:textAppearance="#android:style/TextAppearance.Holo.Medium" />
<TextView
android:id="#+id/row_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="#string/Common_TextContent"
android:textAppearance="#android:style/TextAppearance.Holo.Small" /></LinearLayout>
the custom Adapter:
public class ItemsListAdapter extends ArrayAdapter<ItemsList> {
private int[] colors = new int[] { 0x30ffffff, 0x30808080 };
public AssetListAdapter(Context context,
List<ItemsList> itemsList) {
super(context, 0, itemsList);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.row, null);
}
convertView.setBackgroundColor(colors[position % colors.length]);
TextView code = (TextView) convertView.findViewById(R.id.row_code);
code.setText(getItem(position).getCode());
TextView name = (TextView) convertView.findViewById(R.id.row_name);
name.setText(getItem(position).getName());
return convertView;
}
and the onCreate method on the Activity
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
_listView = (ListView) findViewById(R.id.listview_items);
_listItems = new ArrayList<ItemsList>();
_listItems.add(new ItemsList ("cosa1", "cosa1", "cosa1", "cosa1"));
_listItems.add(new ItemsList ("cosa2", "cosa2", "cosa2", "cosa2"));
_listItems.add(new ItemsList ("cosa3", "cosa3", "cosa3", "cosa3"));
_adapter = new ItemsListAdapter(this, _listItems);
_listView.setAdapter(_adapter);
}
The ItemsList is just an Object with 4 strings with all the getters implemented.
When I debug in the getView method of the Adapter, the view (convertView) is created and it has the right information. It is just that is not showing those in the screen. What am I doing wrong?
Thanks...
Your second LinearLayout has a height of match_parent. Try wrap_content instead.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp">
