I am developing a weather app in which i wanted to use two Views inside RecyclerView which is having CursorAdapter as its member. I want to use one View to display todays weather and other view to display other days weathers. My RecyclerView is working perfectly and i even displaying the two layouts but not correctly i.e layout i want to use for today's weather is used by tomorrow weather and second last day in the list
Following is the code for my RecyclerView Adapter :-
public class WeatherAdapter extends RecyclerView.Adapter<WeatherAdapter.ViewHolder> {
private static int VIEW_TYPE_TODAY = 0;
private static int VIEW_TYPE_FUTURE_DAY = 1;
private static final int VIEW_TYPE_COUNT = 2;
public CursorAdapter mCursorAdapter;
private Context mContext;
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public class ViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
TextView date,weather,min,max;
ImageView icon;
public ViewHolder(View itemView) {
super(itemView);
date =(TextView) itemView.findViewById(R.id.list_item_date_textview);
weather = (TextView) itemView.findViewById(R.id.list_item_forecast_textview);
min = (TextView) itemView.findViewById(R.id.list_item_low_textview);
max = (TextView) itemView.findViewById(R.id.list_item_high_textview);
icon = (ImageView) itemView.findViewById(R.id.list_item_icon);
}
}
// Provide a suitable constructor (depends on the kind of dataset)
public WeatherAdapter(Context context, Cursor c,int flags) {
mContext = context;
mCursorAdapter = new CursorAdapter(mContext,c,flags) {
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
int viewType = getItemViewType(cursor.getPosition());
int layoutId = -1;
if(viewType==VIEW_TYPE_TODAY)
layoutId = R.layout.list_item_forecast_today;
else if(viewType==VIEW_TYPE_FUTURE_DAY)
layoutId = R.layout.list_item_forecast;
View view = LayoutInflater.from(context).inflate(layoutId, parent, false);
return view;
}
@Override
public void bindView(View itemView, Context context, final Cursor cursor) {
// our view is pretty simple here --- just a text view
// we'll keep the UI functional with a simple (and slow!) binding.
TextView date,weather,min,max;
ImageView icon;
date =(TextView) itemView.findViewById(R.id.list_item_date_textview);
weather = (TextView) itemView.findViewById(R.id.list_item_forecast_textview);
min = (TextView) itemView.findViewById(R.id.list_item_low_textview);
max = (TextView) itemView.findViewById(R.id.list_item_high_textview);
icon = (ImageView) itemView.findViewById(R.id.list_item_icon);
int weatherId = cursor.getInt(ForecastFragment.COL_WEATHER_ID);
icon.setImageResource(R.drawable.ic_launcher);
long dateId = cursor.getLong(ForecastFragment.COL_WEATHER_DATE);
date.setText(Utility.getDayName(mContext,dateId));
String weatherDesc = cursor.getString(ForecastFragment.COL_WEATHER_DESC);
weather.setText(weatherDesc);
boolean isMetric = Utility.isMetric(mContext);
double high = cursor.getDouble(ForecastFragment.COL_WEATHER_MAX_TEMP);
max.setText(Utility.formatTemperature(high, isMetric) + "/");
double low = cursor.getDouble(ForecastFragment.COL_WEATHER_MIN_TEMP);
min.setText(Utility.formatTemperature(low, isMetric));
}
@Override
public int getViewTypeCount() {
return VIEW_TYPE_COUNT;
}
@Override
public int getItemViewType(int position) {
Log.e("getItemViewType: ",""+position);
if(position == VIEW_TYPE_TODAY)
return VIEW_TYPE_TODAY;
else
return VIEW_TYPE_FUTURE_DAY;
}
};
}
// Create new views (invoked by the layout manager)
@Override
public WeatherAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
View v = mCursorAdapter.newView(mContext, mCursorAdapter.getCursor(), parent);
return new ViewHolder(v);
}
// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
mCursorAdapter.getCursor().moveToPosition(position);
mCursorAdapter.bindView(holder.itemView, mContext, mCursorAdapter.getCursor());
Cursor cursor = mCursorAdapter.getCursor();
cursor.moveToPosition(position);
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Cursor cursor = mCursorAdapter.getCursor();
cursor.moveToPosition(position);
if (!cursor.isClosed()) {
String locationSetting = Utility.getPreferredLocation(mContext);
Intent intent = new Intent(mContext.getApplicationContext(), DetailActivity.class)
.setData(WeatherContract.WeatherEntry.buildWeatherLocationWithDate(
locationSetting, cursor.getLong(ForecastFragment.COL_WEATHER_DATE)
));
mContext.startActivity(intent);
}
}
});
}
// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
return mCursorAdapter.getCount();
}
}
I am not able to understand what wrong in my implementation.Thanks in advanced
