baseadapter

I have simple code snippet to implement custom list view. In this code, I have CustomAdapter class which extends ArrayAdapter : CustomAdapter adapter = new CustomerAdapter(getApplicationContext(),R.layout.listview_item_row, weather_data); The constructor of CustomAdapter is as below: public CustomerAdapter(Context context, int layoutResourceId, weather[] data) { super(context, layoutResourceId, data); mlayoutResourceId = layoutResourceId; mcontext = context; mdata = data; } If I write this, the logcat shows following error: Java.lang.ClassCastException: android.app.Application context can not

I am having a weird issue in my app. In one of my app activity I am inflating three fragments in it with tabs. Everything works fine. In the fragment in which I am having problem, I have listview which is inflated using adapter and data fro web service. This also works well. Now the problem is this the row which is inflated in adapter, has a hidden view which has visibility=gone in xml. On tap of imageview from that row I make that layout visible through java code. The problem is layout doesn't become visible on tap. I have even set breakpoint on the onClickListener of imageview and it does

This is a piece of code from my adapter class public static class ItemAdapter extends BaseAdapter { private String[] mData; private LayoutInflater mInflater; // I called this method to change data public void setEditText(int position, final String item) { mData[position] = item; notifyDataSetChanged(); } } I change data at some dialog like this

I would like to ask why CursorAdapter splits the process of creating a view and populating it with data into newView() and bindView() while BaseAdapter only does this with getView() ?
