I'm trying to create a custom cursoradapter that will use two different layouts depending on some data in the cursor. I keep reading about 'overriding getViewTypeCount() and getItemViewType()' to make this happen but I can't seem to figure out how to implement this..
This is my code for the bindView and new View methods:
@Override
public void bindView(View view, Context context, Cursor cursor) {
TextView tView = (TextView) view.findViewById(R.id.TextView1);
tView.setText("The text");
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return mInflater.inflate(R.layout.item1, parent, false);
}
.
EDIT: Now I got this working, but I want to choose what rowlayout to use depending on some data in the cursor and I can't get that working.. anybody got some ideas?
@Override
public int getItemViewType(int position) {
return position % 2;
}
@Override
public int getViewTypeCount() {
return 2;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
ViewHolder holder = (ViewHolder) view.getTag();
holder.txtAddress
.setText("blabla");
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
ViewHolder holder = new ViewHolder();
View v = null;
int type = cursor.getPosition() % 2;
if(type == 0) {
v = mInflater.inflate(R.layout.item, parent, false);
} else {
v = mInflater.inflate(R.layout.item2, parent, false);
}
holder.txtAddress = (TextView) v.findViewById(R.id.tvName);
v.setTag(holder);
return v;
}
So I finally got it work. For the ones interested the working code is below:
private int getItemViewType(Cursor cursor) {
String type = cursor.getString(cursor.getColumnIndex("type"));
if (type.equals("1")) {
return 0;
} else {
return 1;
}
}
@Override
public int getItemViewType(int position) {
Cursor cursor = (Cursor) getItem(position);
return getItemViewType(cursor);
}
@Override
public int getViewTypeCount() {
return 2;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
ViewHolder holder = (ViewHolder) view.getTag();
holder.textView
.setText(cursor.getString(cursor.getColumnIndex("body")));
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
ViewHolder holder = new ViewHolder();
View v = null;
if (cursor.getString(cursor.getColumnIndex("type")).equals("1")) {
v = mInflater.inflate(R.layout.message1, parent, false);
holder.textView = (TextView) v
.findViewById(R.id.textView1);
} else {
v = mInflater.inflate(R.layout.message2, parent, false);
holder.textView = (TextView) v
.findViewById(R.id.textView2);
}
v.setTag(holder);
return v;
}
public static class ViewHolder {
public TextView textView;
}
Take a look to this example, you can easily adapt it for solving your problem. It's pretty straightforward.
