Optimize lists a 150%
We can optimize the Adapters
attached to a ListView
inflating our custom layouts when it is necessary. This process is easy to implement with only one condition (Android will managed the rest of the work).
// MyAdapter.java
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
if (row == null) {
LayoutInflater inflater = (LayoutInflater) this.mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.your_row_layout, null);
}
// Populate row
// ...
return row;
}
