make a List of HashMap type in recycler view adapter

I am using this liabray for swipe gestures. https://github.com/nikhilpanju/RecyclerViewEnhanced.
In the MainAdapter.java class recyclerView contains List but i want to replace this to List> type. When i do this, so many errors appear. Kindly guide me how can i do this or suggest me any tutorial to do that.
MainAdapter.java
public class MainAdapter extends RecyclerView.Adapter<MainAdapter.MainViewHolder> {
LayoutInflater inflater;
List<RowModel> modelList;
public MainAdapter(Context context, List<RowModel> list) {
inflater = LayoutInflater.from(context);
modelList = new ArrayList<>(list);
}
#Override
public MainViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = inflater.inflate(R.layout.recycler_row, parent, false);
return new MainViewHolder(view);
}
#Override
public void onBindViewHolder(MainViewHolder holder, int position) {
holder.bindData(modelList.get(position));
}
#Override
public int getItemCount() {
return modelList.size();
}
class MainViewHolder extends RecyclerView.ViewHolder {
TextView mainText, subText;
public MainViewHolder(View itemView) {
super(itemView);
mainText = (TextView) itemView.findViewById(R.id.mainText);
subText = (TextView) itemView.findViewById(R.id.subText);
}
public void bindData(RowModel rowModel) {
mainText.setText(rowModel.getMainText());
subText.setText(rowModel.getSubText());
}
}
}
Activity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_admin_panel);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
unclickableRows = new ArrayList<>();
unswipeableRows = new ArrayList<>();
dialogItems = new String[25];
for (int i = 0; i < 25; i++) {
dialogItems[i] = String.valueOf(i + 1);
}
mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView);
mAdapter = new MainAdapter(this, getData());
mRecyclerView.setAdapter(mAdapter);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
onTouchListener = new RecyclerTouchListener(this, mRecyclerView);
onTouchListener
.setIndependentViews(R.id.rowButton)
.setViewsToFade(R.id.rowButton)
.setClickable(new RecyclerTouchListener.OnRowClickListener() {
#Override
public void onRowClicked(int position) {
util.shortToast(getApplicationContext(), "Row " + (position + 1) + " clicked!");
}
#Override
public void onIndependentViewClicked(int independentViewID, int position) {
util.shortToast(getApplicationContext(), "Button in row " + (position + 1) + " clicked!");
}
})
.setSwipeOptionViews(R.id.add, R.id.edit, R.id.change)
.setSwipeable(R.id.rowFG, R.id.rowBG, new RecyclerTouchListener.OnSwipeOptionsClickListener() {
#Override
public void onSwipeOptionClicked(int viewID, int position) {
String message = "";
if (viewID == R.id.add) {

} else if (viewID == R.id.change) {

}
message += " clicked for row " + (position + 1);
util.shortToast(getApplicationContext(), message);
}
});
mRecyclerView.addOnItemTouchListener(onTouchListener);
// Detect touched area
detector = new Swipe(this,this);
db = new DB(getApplicationContext());
Bundle bundle = getIntent().getExtras();
if(bundle != null) {
String id = bundle.getString("id");
Toast.makeText(this, "Welcome " + db.getUsernameById(id), Toast.LENGTH_LONG).show();

}
public void showAllUsers() {
try {
Cursor cursor = db.selectAllUsers();
cursor.moveToFirst();
adapter.clear();
if (cursor.getCount() == 0) {
Toast.makeText(this, "Empty user list", Toast.LENGTH_SHORT).show();
} else {
for (int i = 0; i < cursor.getCount(); i++) {
HashMap<String, Object> hm = new HashMap<String, Object>();
hm.put(ID, cursor.getString(cursor.getColumnIndex(db.ID_USER)));
hm.put(USERNAME, cursor.getString(cursor.getColumnIndex(db.NAME_USER)));
arrayList.add(hm);
cursor.moveToNext();
}
}
} catch (Exception e) {
Log.d("Show users", " failed due to " + e.getMessage());
}
}
// Swipe interface
#Override
public void onSwipe(int direction) {
String str = "";
switch (direction) {
case Swipe.SWIPE_RIGHT :
listView.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
//deleteUser(id);
Toast.makeText(AdminPanel.this, "user deleted", Toast.LENGTH_LONG).show();
}
});
str = "Swipe Right";
break;
case Swipe.SWIPE_LEFT : str = "Swipe Left";
break;
case Swipe.SWIPE_DOWN : str = "Swipe Down";
break;
case Swipe.SWIPE_UP : str = "Swipe Up";
break;
}
Toast.makeText(this, str, Toast.LENGTH_SHORT).show();
}
#Override
public void onDoubleTap() {
Toast.makeText(this, "Double Tap", Toast.LENGTH_SHORT).show();
}
#Override
public boolean dispatchTouchEvent(MotionEvent ev) {
if (touchListener != null) touchListener.getTouchCoordinates(ev);
return super.dispatchTouchEvent(ev);
}
#Override
public void setOnActivityTouchListener(OnActivityTouchListener listener) {
this.touchListener = listener;
}
private List<RowModel> getData() {
List<RowModel> list = new ArrayList<>(25);
for (int i = 0; i < 25; i++) {
list.add(new RowModel("Row " + (i + 1), "Some Text... "));
}
return list;
}
}

you can change your getData() method and make it return HashMap.
private HashMap <String,String> getData() {
HashMap <String,String> list = new HashMap <String,String>();
for (int i = 0; i < 25; i++) {
list.put(i,"Text");
}
return list;
}
now in your Adapter you can handle it like...
public class MainAdapter extends RecyclerView.Adapter<MainAdapter.MainViewHolder> {
LayoutInflater inflater;
<HashMap<String,String> modelList;
public MainAdapter(Context context, <HashMap<String,String> modelList) {
this.inflater = LayoutInflater.from(context);
this.modelList = modelList;
}
#Override
public MainViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = inflater.inflate(R.layout.recycler_row, parent, false);
return new MainViewHolder(view);
}
#Override
public void onBindViewHolder(MainViewHolder holder, int position) {
//holder.bindData();
holder.mainText.setText(modelList.get(position)); // value for the given key
}
#Override
public int getItemCount() {
return modelList.size();
}
class MainViewHolder extends RecyclerView.ViewHolder {
TextView mainText, subText;
public MainViewHolder(View itemView) {
super(itemView);
mainText = (TextView) itemView.findViewById(R.id.mainText);
subText = (TextView) itemView.findViewById(R.id.subText);
}
}
}

Using onclicklistener in a Fragmentactivity?

i have prepared an onclicklistener listview to put in a tab menu but after all done, i have noticed that such thing is not possible, i dont know may be with a small change to the code i can achieve what i need but my brain seriously stopped due to fraustrating:( :

i think what you need is navigation drawer
or you can use action bar

Converting ListActivity to ListFragment

ListFragment will provide you with all what you need like ListActivity. You need to make a new Activity (Main Activity) extends FragmentActivity and make the ListFragment as a different class then add the Fragment to the Activity. If you don't know how to do this I strongly recommend you read The Fragments Tutorial Here.

Here is the whole fragment.

If Both classes Item and CustomAdapter reside in same java file then you need to remove public keyword from Item class.
Java only permits one public class on a .java file since Java designers chose a strict approach that enforces their idea of good design practices, and this is part of that theme.

It looks like your:
public class Item
is outside your CustomAdapter class, move it inside CustomAdapter class, or make Item non public class.
Also, if you move it inside your CustomAdapter then consider making it static class. From your code you are not using enclosing class (here CustomAdapter) inside Item, so there is no need to make Item non static.
