How to populate a GridView from a Cursor with custom layout in Fragment

I did some research but wasn't able to find a good example.
Current setup:
ArrayList<String> arrCursor = new ArrayList<String>();
List<mydata> md = mydatabase.getthedata("1");
for (mydata cn1 : md) {
arrCursor.add(cn1.getTheFirst());
arrCursor.add(cn1.getTheSecond());
}
ArrayAdapter arrayAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, arrCursor);
gv.setAdapter(arrayAdapter); //the gridview
GridView layout:
<FrameLayout 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.myapp.chao">
<GridView
android:id="#+id/gvalldata"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="auto_fit"
android:gravity="center"
android:stretchMode="columnWidth"
android:columnWidth="90dp"
android:horizontalSpacing="10dp"
android:verticalSpacing="10dp" />
</FrameLayout>
The above only displays a simple list rather than a custom one.
To start the custom adapter process, I have setup an item list 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"
android:orientation="vertical"
android:padding="10dp">
<TextView
android:text="TextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/tvfirst"
android:layout_marginBottom="10dp"
android:gravity="center"
android:textSize="25dp" />
<TextView
android:text="TextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/tvsecond" />
</LinearLayout>
How can I add a custom adapter which will show the gridview using the item list layout and in boxes.
What I am looking for:

This should work make custom adapter and set that adapter to gridview
gv.setAdapter(new CustomAdapter(this, prgmNameList,prgmImages));
public class CustomAdapter extends BaseAdapter{
String [] result;
Context context;
int [] imageId;
private static LayoutInflater inflater=null;
public CustomAdapter(MainActivity mainActivity, String[] prgmNameList, int[] prgmImages) {
// TODO Auto-generated constructor stub
result=prgmNameList;
context=mainActivity;
imageId=prgmImages;
inflater = ( LayoutInflater )context.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return result.length;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public class Holder
{
TextView tv;
ImageView img;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
Holder holder=new Holder();
View rowView;
rowView = inflater.inflate(R.layout.program_list, null);
holder.tv=(TextView) rowView.findViewById(R.id.textView1);
holder.img=(ImageView) rowView.findViewById(R.id.imageView1);
holder.tv.setText(result[position]);
holder.img.setImageResource(imageId[position]);
rowView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "You Clicked "+result[position], Toast.LENGTH_LONG).show();
}
});
return rowView;
}
}

Try inserting your own custom layout (R.layout.custom_layout) in the ArrayAdapter constructor instead of the android one (***android.**R.layout.simple_list_item_1*)
so E.g
ArrayAdapter arrayAdapter = new ArrayAdapter(getActivity(), R.layout.custom_layout, arrCursor);

Android gridview in a fragment showing nothing

I am creating a gridview with different images and texts from a class containing those images and texts in a fragment. The GridView is inside a TabHost. The TabHost is working fine. I can see other buttons in the same view. But nothing is inside the GridView. Here is the code:
public class MenuPage extends Fragment{
GridView CategoryGridview;
View MainMenuView, HomePageView, GalleryView;
#Override
public void onAttach(Activity activity) {
// TODO Auto-generated method stub
super.onAttach(activity);
}
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final Context context = getActivity();
this.MainMenuView = inflater.inflate(R.layout.mainmenupage, container, false);
this.GalleryView = inflater.inflate(R.layout.gallery, container, false);
this.CategoryGridview = (GridView)GalleryView.findViewById(R.id.gridViewGallery);
CategoryGridview.setAdapter(new GalleryAdapter(getActivity()));
:
:
:
return MainMenuView;
}
Adapter:
public class GalleryAdapter extends BaseAdapter{
ArrayList<Gallery> list;
Context context;
GalleryAdapter(Context context){
this.context = context;
list = new ArrayList<Gallery>();
int[] TempGalleryId = {R.drawable.a, R.drawable.b, R.drawable.c, R.drawable.d, R.drawable.e, R.drawable.f, R.drawable.g, R.drawable.h, R.drawable.i, R.drawable.j, R.drawable.k, R.drawable.l, R.drawable.m, R.drawable.n, R.drawable.o, R.drawable.p, R.drawable.q, R.drawable.r, R.drawable.s};
String[] TempGalleryName = {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s"};
for (int i = 0; i < 19; i++){
Gallery TempGallery = new Gallery(TempGalleryId[i], TempGalleryName[i]);
list.add(TempGallery);
}
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return list.get(position);
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View row = convertView;
ViewHolder holder = null;
if(row == null){
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.single_gallery, parent, false);
holder = new ViewHolder(row);
row.setTag(holder);
}
else{
holder = (ViewHolder) row.getTag();
}
Gallery temp = list.get(position);
holder.imageViewGallery.setImageResource(temp.GalleryId);
return row;

In mainmenupage.xml, one of the tab include gallery.xml file for animation with a gridview imageViewGallery and some buttons in it.

I tried change
CategoryGridview.setAdapter(new GalleryAdapter(getActivity()));
to
CategoryGridview.setAdapter(new GalleryAdapter(context));
and
this.CategoryGridview = GridView)MainMenuView.findViewById(R.id.gridViewGallery);
to
this.CategoryGridview = (GridView)GalleryView.findViewById(R.id.gridViewGallery);
still doesn't work.
I also tried open a new project with extend Activity(){}. It work fine with
CategoryGridview.setAdapter(new GalleryAdapter(this));
So I guess the problem is somewhere else. Can anyone help?

It probably happens because before bitmaps get loaded and saved to your array, you call adapter. Downloading images takes some time and your adapter is not waiting for them. See this example, it is using image loader: http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/

Are there any NetworkOnMainThreadException in the log ?
When calling getBitmapFromUrl from onCreate, you are downloading the bitmap on the main thread, which is prohibited if your application is targeting Honeycomb or later. In your case it will fail silently because you are catching the exception but you will get a null result.
As loading images from network is very common, there are a lot of library that handle this (and a lot more like caching) for you, e.g. Universal-Image-Loader
or ion

get check box from listview baseadapter

I have List view in layout

the question I want to get checked values from checkbox and return it to my activity

I found the solution
first make a static Boolean variable
static Boolean checkboxstate[];
then define it in the constructor with the size of the list
checkboxstate=new Boolean[messageNo.length];
then make your checkbox on click listener and fill the boolean array
if(checkboxstate[position]==null){
checkboxstate[position]=false;
}
cb.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(((CheckBox)v).isChecked()){
checkboxstate[position]=true;
v.setSelected(true);
}else{
checkboxstate[position]=false;
v.setSelected(false);
}
}
});
finally
public class ImageInboxAdapter extends BaseAdapter{
Context context;
String[] messageNo,messageTitle,senderId,senderName;
Bitmap[] bitmap;
Boolean selected;
static Boolean checkboxstate[];
int checkedp;
public ImageInboxAdapter(Context context, Bitmap[] bitmap,String[] messageNo,String[] messageTitle, String[] senderId,String[] senderName,Boolean selected) {

How to add ImageView, TextView and Button in ListView in android

In my application I am trying to create a ListView that contains an ImageView a TextView and a Button. I have created a separate XML file and drag all the above mentioned elements in that XML and in my main java file I have created an Object of BaseAdapter and in the getView() method I have declared these elements but when I run the application I cant see the list. I haven't used the BaseAdapter, so I am missing with some code in order to view the List. I also want to apply some operations on the button so please let me know that code also.
Code for my main.xml file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
Code for my list_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="75dp"
android:layout_height="75dp"
android:scaleType="fitXY"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="50dp"
android:layout_marginTop="25dp"
android:text="Button" />
</LinearLayout>
Code for my main.java file:
public class CustomListActivity extends Activity {
/** Called when the activity is first created. */
ListView lv;
LayoutInflater inflator;
#Override
