my app always crash,i try to access a fragment that displays a cardview using RecyclerView.
Here is my Fragment
public class Fragmentone extends Fragment {
private RecyclerView recyclerView;
private List<TestBean> listItem;
private RecyclerAdapter adapter;
public Fragmentone() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_fragmentone, container, false);
recyclerView = (RecyclerView) view.findViewById(R.id.recyclerview);
initData();
adapter = new RecyclerAdapter(listItem,getActivity());
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
recyclerView.setHasFixedSize(true);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(adapter);
return view;
}
private void initData() {
listItem = new ArrayList<>();
listItem.add(new TestBean("佛山傻逼酒店","二月17号","二月18号","600","已付款"));
}
}
and this is my adapter
public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ListViewHolder> {
private List<TestBean> listitem;
private Context context;
public RecyclerAdapter(List<TestBean> listitem, Context context) {
this.listitem = listitem;
this.context = context;
}
#Override
public ListViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(context).inflate(R.layout.card_item, viewGroup, false);
ListViewHolder listViewHolder = new ListViewHolder(v);
return listViewHolder;
}
#Override
public void onBindViewHolder(ListViewHolder holder, int i) {
holder.tv_roomfee.setText(listitem.get(i).getRoomfee());
holder.tv_hotelname.setText(listitem.get(i).getHotelname());
holder.tv_liststate.setText(listitem.get(i).getListstate());
holder.tv_checkindate.setText(listitem.get(i).getCheckindate());
holder.tv_lastcheckindate.setText(listitem.get(i).getLastcheckindate());
holder.btn_paynow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
holder.btn_cancellist.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
#Override
public int getItemCount() {
return listitem.size();
}
public class ListViewHolder extends RecyclerView.ViewHolder {
CardView id_cardview;
TextView tv_roomfee;
TextView tv_liststate;
TextView tv_hotelname;
TextView tv_checkindate;
TextView tv_lastcheckindate;
Button btn_paynow;
Button btn_cancellist;
public ListViewHolder(final View itemView) {

tv_checkindate = (TextView) itemView.findViewById(R.id.tv_checkindate);
tv_lastcheckindate = (TextView) itemView.findViewById(R.id.tv_lastcheckindate);
btn_paynow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
btn_cancellist.setOnClickListener(new View.OnClickListener() {
#Override

});
}
}
}

I tried below code to implement an expend and collapse content using recyclerview(listview) a link
final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
if (isExpanded)
previousExpandedPosition = position;
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mExpandedPosition = isExpanded ? -1:position;
notifyItemChanged(previousExpandedPosition);
notifyItemChanged(position);
}
});
In my case when i click the particular position in recyclerview its expanding but it goes above the recyclerview.I cant see the full expanded content.i can see only partial content.In this case i need to scroll the recyclerview to view the full content.But i am searching for a solution to view the content without scroll the recyclerview. If i click another position in recyclerview that should be placed over an recyclerview.
Hear is My Code

Try to use NestedScrollView instead of ScrollView and set below to your activity :-
recyclerView.setNestedScrollingEnabled(false);
For more information you can refer below stackoverflow links:-
How to use RecyclerView inside NestedScrollView?
Recyclerview inside ScrollView not scrolling smoothly
I am searching for a long time on net. But no use. Please help or try to give some ideas how to solve this problem.

DishesAdapter constructor is being called. I am getting follower1 log along with the list of items.
I have created RecyclerView. When it renders on screen it shows only one item per screen. I can see next item when I scroll down RecyclerView. Here is my code
public class LeaveStatusViewAdapter extends RecyclerView
.Adapter<LeaveStatusViewAdapter
.DataObjectHolder> {
private static String LOG_TAG = "MyRecyclerViewAdapter";
private ArrayList<Employee> mDataset;
private static MyClickListener myClickListener;
public static class DataObjectHolder extends RecyclerView.ViewHolder
implements View
.OnClickListener {
TextView startDate;
TextView endDate;
TextView leaveType;
TextView leaveDays;
TextView leaveReason;
TextView leaveStatus;
public DataObjectHolder(View itemView) {
super(itemView);
startDate = (TextView) itemView.findViewById(R.id.textView_StartDate);
endDate = (TextView) itemView.findViewById(R.id.textView_EndDate);
leaveType = (TextView) itemView.findViewById(R.id.textView_LeaveType);
leaveDays = (TextView) itemView.findViewById(R.id.textView_LeaveDays);
leaveReason = (TextView) itemView.findViewById(R.id.textView_LeaveReason);
leaveStatus = (TextView) itemView.findViewById(R.id.textView_LeaveStatus);
Log.i(LOG_TAG, "Adding Listener");
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
myClickListener.onItemClick(getAdapterPosition(), v);
}
}
public void setOnItemClickListener(MyClickListener myClickListener) {
this.myClickListener = myClickListener;
}
public LeaveStatusViewAdapter(ArrayList<Employee> myDataset) {
mDataset = myDataset;
}
#Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.card_view_row, parent, false);
DataObjectHolder dataObjectHolder = new DataObjectHolder(view);
return dataObjectHolder;
}
#Override
public void onBindViewHolder(DataObjectHolder holder, int position) {
holder.startDate.setText(mDataset.get(position).getLeaveStartDate());
holder.endDate.setText(mDataset.get(position).getLeavesEndDate());
holder.leaveType.setText(mDataset.get(position).getLeaveType());
holder.leaveDays.setText(mDataset.get(position).getLeaveDays());
holder.leaveReason.setText(mDataset.get(position).getLeaveReason());
holder.leaveStatus.setText(mDataset.get(position).getLeaveStatus());
}
public void addItem(Employee dataObj, int index) {
mDataset.add(index, dataObj);
notifyItemInserted(index);
}
public void deleteItem(int index) {
mDataset.remove(index);
notifyItemRemoved(index);
}
#Override
public int getItemCount() {
return mDataset.size();
}
public interface MyClickListener {
public void onItemClick(int position, View v);
}
}
Following is activity class
public class LeaveStatusActivity extends AppCompatActivity {
private RecyclerView mRecyclerView;
private RecyclerView.Adapter mAdapter;
private RecyclerView.LayoutManager mLayoutManager;
private static String LOG_TAG = "CardViewActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_leave_status);
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new LeaveStatusViewAdapter(getDataSet());
mRecyclerView.setAdapter(mAdapter);
}
#Override
protected void onResume() {
super.onResume();
((LeaveStatusViewAdapter) mAdapter).setOnItemClickListener(new LeaveStatusViewAdapter
.MyClickListener() {
#Override
public void onItemClick(int position, View v) {
Log.i(LOG_TAG, " Clicked on Item " + position);
}
});
}
private ArrayList<Employee> getDataSet() {
ArrayList results = new ArrayList<Employee>();
for (int index = 0; index < 3; index++) {
Employee obj = new Employee(" : 15/07/2016",
" : 20/07/2016"," : EL: Earned Leave"," : 5"," : Not feeeling well"," : Pending");
results.add(index, obj);
}
return results;
}
}

Am I missing something here??
You should change the view of each element of the list to android:layout_height="wrap_content"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.CardView
android:id="#+id/card_view"
android:layout_gravity="center"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp">
.....
</LinearLayout>
When you use android:layout_height="match_parent" every item of the list will try to use the maximum space possible in the screen
I have an activity with viewpager inside it and inside one of the fragment i am using a Recycler view with view item as edit text. Here is my code.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FFFF00"
android:gravity="center_vertical"
android:orientation="horizontal"
android:padding="#dimen/five">
<CheckBox
android:id="#+id/checkbox"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="top"
android:padding="#dimen/three" />
<EditText
android:id="#+id/etEditorListItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
android:hint="#string/et_add_item"
android:padding="#dimen/three"/>
</LinearLayout>
Here i have given edittext width as match_parent ( android:layout_width="match_parent") but while running it's getting wrapped based on the width of the hint.
Can someone help me with this.
Adapter:
public class ListAdapter extends RecyclerView.Adapter<NoteListAdapter.ListHolder> {
private List<String> mList = new ArrayList<String>();
private Context mContext;
public ListAdapter(List<String> list){
this.mList = list;
}
#Override
public ListHolder onCreateViewHolder(ViewGroup parent, int viewType) {
this.mContext = parent.getContext();
return new ListHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item,null));
}
#Override
public void onBindViewHolder(final ListHolder holder, final int position) {
holder.etEditorListItem.setText(mList.get(position));
}
#Override
public int getItemCount() {
return mList != null ? mList.size() : 0;
}
public class ListHolder extends RecyclerView.ViewHolder{
public CheckBox checkBox;
public EditText etEditorListItem;
public ListHolder(View itemView) {
super(itemView);
checkBox = (CheckBox)itemView.findViewById(R.id.checkbox);
etEditorListItem = (EditText)itemView.findViewById(R.id.etEditorListItem);
}
}
}
Fragment :
RecyclerView rvList = (RecyclerView) view.findViewById(R.id.rvList);
rvList.setHasFixedSize(true);
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
rvList.setLayoutManager(layoutManager);
mListAdapter = new ListAdapter(listItems);
rvList.setAdapter(mListAdapter);
Fragment layout:
<android.support.v7.widget.RecyclerView
android:id="#+id/rvList"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
Try this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:orientation="horizontal"
android:background="#FFFF00"
android:weightSum="1"
android:padding="5dp">
<CheckBox
android:id="#+id/checkbox"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_weight="0.1"
android:padding="3dp"/>
<EditText
android:id="#+id/etEditorListItem"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#null"
android:layout_gravity="center_horizontal"
android:layout_weight="0.9"
android:hint="Hello"
android:padding="3dp"/>
