   holder.txtTitle.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) 
        {
            System.out.println("hhhhhhhhhhhhhhhhhhhh");

You are using this into listener then it will belongs to listener object. But you need Context object to declare the Intent. So you need to change this with YOUR_ACTIVITY_NAME.this.

Change

Intent i2 = new Intent(this,ImageSelection.class);
startActivity(i2);

to

Intent i2 = new Intent(YOUR_ACTIVITY.this,ImageSelection.class);
YOUR_ACTIVITY.this.startActivity(i2);

Ohh yes you are trying to start activity from adapter.

Then it should be

Intent i2 = new Intent(context_object_which_is_in_adapter, ImageSelection.class);
context_object_which_is_in_adapter.startActivity(i2);

You are trying to start another activity from your Custom ListView Adapter, right?

Than do this:

     Intent i2 = new Intent(mContext ,ImageSelection.class);
     mContext.startActivity(i2);

where mContext is the Context of the calling activity.
