Answer 1

Create a listview in your main xml file like this:

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/masterLayout"
 android:orientation="vertical" 
 android:layout_width="wrap_content"
 android:layout_height="wrap_content">
    <ListView
     android:id="@+id/list"
     android:cacheColorHint="#00000000"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"/>
</LinearLayout>

Then create another xml file called child_layout:

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content">
     <ImageView android:id="@+id/image"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"/>
</RelativeLayout>

Then in your activity class initialize your listview:

ListView listView1 = (ListView)findViewById(R.id.list);

Create a class that extends baseadapter and modify all the necessary methods the way you need to (create the constructor that takes a list of drawables as an argument and create a global variable that is set to the provided list). Then do the following in your activity class:

ArrayList<Drawable> images = new ArrayList<Drawable>();
// add to the list here
CustomListAdapter adapter = new CustomListAdapter(images);
listView1.setAdapter(adapter);

Do this in your getView() function in your customlistadapter class:

public View getView(int position, View convertView, ViewGroup parent)
{
    Drawable image = images.get(position);
    if (convertView == null)
    {
        LayoutInflater infalInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.child_layout, null);
    }
    ImageView imageView = (ImageView)convertView.findViewById(R.id.image);
    imageView.setBackgroundDrawable(image);

    return convertView;
}

ListView item click listener:

listView1.setOnItemClickListener(new ListView.OnItemClickListener()
{
    public void onItemClick(AdapterView<?> listView, View itemView, int position, long itemId)
    {
        String message = "example text: " + position;
        Toast.makeText(MyActivity.this, message, Toast.LENGTH_SHORT).show();
    }
});

You need to create a Custom ListAdapter. An Example is give in API samples. Just add an ImageView as the layout of the custom adapter and you should get going. Search more for the examples.

Answer 3

take one main layout xml file in which you have to give the . something like this

     <List
       android:width="wrap_content"
       android:height="wrap_content"
       android:id="@+id/list"
  />

and take another layout xml file with

<ImageView
     android:width="wrap_content"
     android:height="wrap_content"/>

In the adapter inflate this xml file that contains ImageView. so that you can get image in the list
