I have read copious posts on this, but no solution. After using MAT
extensively on an ApiDemo list view sample, I am ABSOLUTELY convinced
that the ListView/ListActivity is leaking memory.
import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
public class TmpTestActivity extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new MyListAdapter(this));
}
@Override
protected void onDestroy()
{
super.onDestroy();
final MyListAdapter mla =
(MyListAdapter)getListView().getAdapter();
mla.onDestroy();
// here I tried setting the activity's contained ListView's
onItemClickListener to null
getListView().setOnItemClickListener(null);
getListView().focusableViewAvailable(null);
}
private static class MyListAdapter extends BaseAdapter {
public void onDestroy()
{
mContext = null;
}
public MyListAdapter(Context context) {
mContext = context;
}
public int getCount() {
return mStrings.length;
}
@Override
public boolean areAllItemsEnabled() {
return false;
}
@Override
public boolean isEnabled(int position) {
return !mStrings[position].startsWith("-");
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup
parent) {
TextView tv;
if (convertView == null) {
tv = (TextView) LayoutInflater.from(mContext).inflate(
android.R.layout.simple_expandable_list_item_1, parent, false);
} else {
tv = (TextView) convertView;
}
tv.setText(mStrings[position]);
return tv;
}
private Context mContext;
private String[] mStrings = {
"----------",
"----------",
"Abbaye de Belloc",
"Abbaye du Mont des Cats",
"Abertam",

}
}
