How to add info icon on textinputlayout when floating label is raised

How to add info icon when floating label is raised just beside hint.
Like this http://prntscr.com/nlipdn
I have tried with below code:
when focus change on edittext.I added info icon.But I don't know how to set info icon beside floating label. I have added but it's not positioning proper.
public void OnFocusChange(View v, bool hasFocus)
{
ImageView _infoView=null;
if (_infoView != null)
{
_songTitleLayout.RemoveView(_infoView);
_infoView = null;
}
if (v==_eSongTitle)
{
if(hasFocus)
{
int length= _songTitleLayout.Hint.Length;
_infoView = new ImageView(this);
_infoView.SetImageResource(Resource.Drawable.MoreInfo);
_songTitleLayout.AddView(_infoView);
}
}
}

Solution:
I add a margin before you add the _inforView by using code below, you can change the values to adjust the margin and size of image:
ViewGroup.MarginLayoutParams paramsw = new ViewGroup.MarginLayoutParams(40,40);
paramsw.SetMargins(200,0,0,0);
CollapsingToolbarLayout.LayoutParams lp = new
CollapsingToolbarLayout.LayoutParams(paramsw);
txtlayoutusername.AddView(_infoView,0,lp);
Here is all the codes I tested:
This is the code in MainActivity:
public class MainActivity : AppCompatActivity
{
TextInputLayout txtlayoutusername;
EditText txtusername;
ImageView _infoView;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.activity_main);
txtlayoutusername = FindViewById<TextInputLayout>(Resource.Id.textuernameInputLayout);
txtusername = FindViewById<EditText>(Resource.Id.txtusername);
txtusername.FocusChange += (object sender, View.FocusChangeEventArgs e) =>
{
if (_infoView != null)
{
txtlayoutusername.RemoveView(_infoView);
_infoView = null;
}
if (sender == txtusername)
{
if (txtusername.IsFocused)
{
int length = txtlayoutusername.Hint.Length;
_infoView = new ImageView(this);
_infoView.SetImageResource(Resource.Drawable.ttt);
ViewGroup.MarginLayoutParams paramsw = new ViewGroup.MarginLayoutParams(40,40);
paramsw.SetMargins(200,0,0,0);
CollapsingToolbarLayout.LayoutParams lp = new CollapsingToolbarLayout.LayoutParams(paramsw);
txtlayoutusername.AddView(_infoView,0,lp);
}
}
};
}
}
Here is code in Xaml:

The result:

How to change the indicator color every different cardview?

This is the adapter :
public class OrderListAdapter extends RecyclerView.Adapter<OrderListAdapter.OrderListViewHolder> {
private ArrayList<OrderListModel> itemOrderList;
public OrderListAdapter(ArrayList<OrderListModel> itemOrderList) {
this.itemOrderList = itemOrderList;
}
#Override
public OrderListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
View view = layoutInflater.inflate(R.layout.order_list_item, parent, false);
return new OrderListViewHolder(view);
}
#Override
public void onBindViewHolder(OrderListViewHolder orderListViewHolder, int position) {
orderListViewHolder.txtDate.setText(itemOrderList.get(position).getDate());
orderListViewHolder.txtOrderNumber.setText(itemOrderList.get(position).getOrderNumber());
orderListViewHolder.txtCustomerName.setText(itemOrderList.get(position).getCustomerName());
orderListViewHolder.txtProductStatus.setText(itemOrderList.get(position).getProductStatus());
orderListViewHolder.txtNotes.setText(itemOrderList.get(position).getNotes());
}
#Override
public int getItemCount() {
return (itemOrderList != null) ? itemOrderList.size() : 0;
// return itemOrderList.size();
}
public class OrderListViewHolder extends RecyclerView.ViewHolder{
private TextView txtDate, txtOrderNumber, txtCustomerName, txtProductStatus,
txtNotes;
public OrderListViewHolder(View itemView) {
super(itemView);
txtDate = (TextView) itemView.findViewById(R.id.txt_order_date);
txtOrderNumber = (TextView) itemView.findViewById(R.id.txt_order_number);
txtCustomerName = (TextView) itemView.findViewById(R.id.txt_customer_name);
txtProductStatus = (TextView) itemView.findViewById(R.id.txt_product_status);
txtNotes = (TextView) itemView.findViewById(R.id.txt_notes);
}
}
}
This is the main :
public class OrderListFragment extends Fragment {
private RecyclerView recyclerView;
private OrderListAdapter adapter;
private ArrayList<OrderListModel> OrderListArrayList;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_order_list, container, false);
getActivity().setTitle(R.string.title_mn_order_list);
addData();
recyclerView = (RecyclerView) view.findViewById(R.id.orderList_recycler_view);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this.getActivity());
recyclerView.setLayoutManager(layoutManager);
adapter = new OrderListAdapter(OrderListArrayList);
recyclerView.setAdapter(adapter);
return view;
}
void addData(){
OrderListArrayList = new ArrayList<>();
OrderListArrayList.add(new OrderListModel(
"4 Juli 2018 10:54",
"0001",
"Jopa",
"No",
"Notes"));
OrderListArrayList.add(new OrderListModel(
"4 Juli 2018 10:54",
"0001",
"Jopa",
"Yes",
"Notes"));
}
}
Do you have any idea how can i change it?

You must give an id to your ImageView say status
In OrderListViewHolder add in your declarations private ImageView status;
In OrderListViewHolder add status = (ImageView) itemView.findViewById(R.id.status);
In OrderListViewHolder add
if (itemOrderList.get(position).getStatus().equals("Yes")) {
orderListViewHolder.status.setBackgroundColor(0x00ff00);
} else {
orderListViewHolder.status.setBackgroundColor(0xff0000); }
of course you must create the getStatus() method like all the others getSomething()

Assuming, that your ImageView is your indicator bar:
<ImageView
android:id="#+id/ivIndicator" <!-- Add this id -->
android:layout_marginLeft="22dp"
android:layout_marginTop="14dp"
android:layout_marginBottom="14dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/rectangle"/>
Get a reference to it in your OrderListViewHolder:
ivIndicator = (ImageView) itemView.findViewById(R.id.ivIndicator);
And then tint your imageview in onBindViewHolder:
if("Yes".equals(itemOrderList.get(position).getStatus())) {
orderListViewHolder.ivIndicator.setColorFilter(ContextCompat.getColor(activity, android.R.color.green))
else {
orderListViewHolder.ivIndicator.setColorFilter(ContextCompat.getColor(activity, android.R.color.red))
}

Make two drawable files like #drawable/rectangle, set it with different color you want.
if(status.equals("No") {
yourView.setBackground(context.getResources().getDrawable(R.drawable.rectangleWithRed));
}
else if (status.equals("Yes") {
yourView.setBackground(context.getResources().getDrawable(R.drawable.rectangleWithGreen);
}

if you want to change the color according to the status, then on onBindViewHolder of your Recycler Adapter, check for the status and set to desired color.
if(status.equals("Yes")
{
rectangleImageView.setColor(Color.GREEN);
}
else
{
rectangleImageView.setColor(Color.RED);
}

public void onBindViewHolder(OrderListViewHolder orderListViewHolder, int position) {
if (OrderListModel.getProductStatus().equals("Yes"))
rectangleImageView.setColorFilter(getContext().getResources().getColor(R.color.green));
} else {
rectangleImageView.setColorFilter(getContext().getResources().getColor(R.color.red));
}
}

Horizontal GridView with customAdaptor not displaying properly

I want to display a single row of 5 images which then I can click on, this is what I hope to get:
[1][2][3][4][5]
This is what I actually get:"____" is a large, long blank area
[1]________________________
[2]________________________
[3]________________________
[4]________________________
[5]________________________
At first I thought there was something up with the orientation so I tried both "horizontal" and "vertical" but nothing worked.
Here is the adaptor code:
public class CustomTopGridMenuAdaptor extends BaseAdapter {
private Context mContext;
private final int[] gridViewImageId;
private ImageView imageViewAndroid;
public CustomTopGridMenuAdaptor(Context context, int[] gridViewImageId) {
mContext = context;
this.gridViewImageId = gridViewImageId;}
#Override
public int getCount() {
return gridViewImageId.length;
}
#Override
public Object getItem(int i) {
return null;
}
public void setImageSource (int i,ImageView v){
imageViewAndroid.setImageResource(gridViewImageId[i]);
}
#Override
public long getItemId(int i) {
return 0;
}
#Override
public View getView(int i, View convertView, ViewGroup parent) {
View gridViewAndroid;
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
gridViewAndroid = new View(mContext);
gridViewAndroid = inflater.inflate(R.layout.android_custom_gridview_layout_top, null);
imageViewAndroid = (ImageView)
gridViewAndroid.findViewById(R.id.android_gridview_image_top);
setImageSource(i,imageViewAndroid);
} else {
gridViewAndroid = (View) convertView;
}
return gridViewAndroid;
}
}
As far as it goes the adaptor is working just fine.
This is the xml file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/android_custom_gridview_layout_top"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:orientation="vertical">
<ImageView
android:id="#+id/android_gridview_image_top"
android:layout_width="50dp"
android:layout_height="50dp"/>
</LinearLayout>
This is the xml segment in the activity layout, where the menu will be displayed:
<GridView
android:id="#+id/android_gridview_menu_top"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ffffff"
android:orientation="horizontal"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0"
app:layout_constraintLeft_toLeftOf="parent"
android:layout_marginStart="196dp">
Can you tell me why it's not working?

Use the android:numColumns="2" in your GridView if you want 5 then change the android:numColumns="5"
<GridView
android:id="#+id/android_gridview_menu_top"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ffffff"
android:numColumns="2"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0"
app:layout_constraintLeft_toLeftOf="parent"
android:layout_marginStart="196dp">

I don't think that gridviews can be made horizontally scrollable. Android has provided HorizontalScrollView it will scroll your view horizontaly. try this.
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<GridView
android:id="#+id/gridView"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</GridView>
</LinearLayout>
</HorizontalScrollView>
Happy coding!!

Android: Dynamically add ImageView to Linearlayout inside Adapter's onBindViewHolder

So I have cardview which contains a textview and linearlayout, and inside the linearlayout I want to add variable number of image views (These views will be holding app icons). How can I achieve this inside RecyclerView's onBindViewHolder.
Code for CardView (Here the linearlayout will hold imageviews):
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_margin="3dp"
android:orientation="horizontal"
card_view:cardCornerRadius="5dp"
card_view:cardUseCompatPadding="true" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:selectableItemBackground">
<TextView
android:id="#+id/profile_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_margin="4sp"
android:gravity="center"
android:textColor="#android:color/black"
android:textSize="12sp" />
<LinearLayout
android:id="#+id/profile_app_icons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true">
</LinearLayout>
<ToggleButton
android:id="#+id/main_page_toggle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_margin="5sp" />
</RelativeLayout>
</android.support.v7.widget.CardView>
Code for Adapter (Which I am trying to implement):
public class ProfileListAdapter extends RecyclerView.Adapter<ProfileListAdapter.ProfileViewHolder>{
private List<ProfileContentsFull> pcf;
ProfileListAdapter(List<ProfileContentsFull> pcf) {
this.pcf = pcf;
}
#Override
public ProfileViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_view_main_page, parent, false);
return new ProfileViewHolder(v);
}
#Override
public void onBindViewHolder(ProfileViewHolder holder, int position) {
holder.profileName.setText(pcf.get(position).getProfileName());
holder.linearLayout.set
}
#Override
public int getItemCount() {
return 0;
}
public static class ProfileViewHolder extends RecyclerView.ViewHolder {
public TextView profileName;
public LinearLayout linearLayout;
public ToggleButton toggle;
public ProfileViewHolder(View itemView) {
super(itemView);
profileName = (TextView) itemView.findViewById(R.id.profile_name);
linearLayout = (LinearLayout) itemView.findViewById(R.id.profile_app_icons);
toggle = (ToggleButton) itemView.findViewById(R.id.main_page_toggle);
}
}
}
Layout containing the recyclerview:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.retr0spect.quit.social.media.addiction.MainActivity"
tools:showIn="#layout/app_bar_main">

android:id="#+id/main_page_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"/>
</RelativeLayout>
Thanks in advance!

You can add ImageView dynamically into LinearLayout like below.
ImageView imageView = new ImageView(holder.linearLayout.getContext());
holder.linearLayout.addView(imageView);
And you can add multipal ImageView by putting above lines within Loop. ImageViews are added only in vertical or Horizontally.

#Override
public void onBindViewHolder(ProfileViewHolder holder, int position) {
holder.profileName.setText(pcf.get(position).getProfileName());
LayoutInflater layoutinflater=(LayoutInflater)getActivity().getSystemService(getActivity().LAYOUT_INFLATER_SERVICE);
holder. linearLayout.removeAllViews();
for (int j = 1; j < pcf.get(position).getImageArray().size(); j++) {
Log.d(TAG, "&& J :" + j);
// inflate the layout
convertView = layoutinflater.inflate(R.layout.adapter_images, null, false);
convertView.setId(j);
ImageView imageView = (ImageView) convertView.findViewById(R.id.iv_image);
//set image here
holder.linearLayout.addView(convertView);
}
}
adapter_images.xml
<ImageView
android:id="#+id/iv_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

ListView item doesn't inflate to wrap content as intended, height == 0 but shouldn't

I am trying to incorporate 2 lists "sections" into a LinearLayout via height weights. The issue that I am having is that, though the container for the "section" is displayed with the proper height (where the background is sub_gray), and the adapter count is correct, the height of my actual list rows is 0 which makes my list appear invisible.
LIST ITEM
Below is the code that my list rows/items directly work with. To avoid the wall of code getting too long, I will include my code for one of the lists seeing as they are both behaving the same.
layout_quick_guide_checklist_item
<?xml version="1.0" encoding="utf-8"?>
<com.my_project.project.QuickGuideChecklistListItemView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
android:background="#color/sub_gray"
android:orientation="horizontal" >
<CheckBox
android:id="#+id/checkbox_checklist"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:layout_gravity="center"
android:checked="true"
android:clickable="false" />
<TextView
android:id="#+id/text_field"
style="#style/default_text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:text="#string/height_wrap_string"/>
</com.my_project.project.QuickGuideChecklistListItemView>
QuickGuideChecklistListItemView
public class QuickGuideChecklistListItemView extends LinearLayout{
private TextView listText;
public QuickGuideChecklistListItemView(Context context) {
super(context);
}
public QuickGuideChecklistListItemView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public QuickGuideChecklistListItemView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}
public static QuickGuideChecklistListItemView inflate(ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) parent.getContext().
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
QuickGuideChecklistListItemView itemView = (QuickGuideChecklistListItemView)
inflater.inflate(R.layout.layout_quick_guide_checklist_item, parent, false);
return itemView;
}
#Override
public void onFinishInflate(){
super.onFinishInflate();
listText = (TextView) findViewById(R.id.text_field);
}
public void setText(String text){
listText.setText(text);
}
}
COMPLETE LIST
Now I take the above code and use it within my activity to create a list (recall; there are actually two lists in my activity, constructed similarly, and both resulting in row heights of 0).

Sorry for the wall of code, but I have tried adjusting everything and just can't seem to get anything to work. So just as a final bit:
The adapters are set, getCount() returns the valid count of items in the list and clicking on the layouts in order to call checkAdapterSize() also results in a Toast with the proper values.
The first view is "inflated" but results in a view height of 0.
The container layouts for my list "sections" (checklist_section in sub_activity_quick_guide for example) have a height which can be seen by the sub_gray background.
I have tried changing height attributes from match_parent to wrap_content and vice versa with no luck. I have tried explicitly declaring a minHeight for my list items and all that good stuff. I just can't seem to ever get a list row item to actually inflate.

Funny how I always manage to figure out an answer to my own questions right after I post a question on SO after days of trying :P
Anyway, the issue was in placing my ListViews inside of LinearLayouts with heights determined by weight. I removed the LinearLayout wrappers for my "sections" and applied the weights to my ListViews directly, voila... good to go.

Hope it helps someone in the future, didn't realize weights would mess with it like that but apparently ListViews don't like weighted containers.
