Listview add item one at a time

I have a listview and a button in my main activity and three layout ressource files (right.xml, mid.xml and left.xml [They're relative layout]).
I want to make an arrayList (with strings and drawable (images)) and each time I push the button in main.xml the first content of the arrayList will appear at the bottom of the screen (either left, mid or right --> depend of the order of the arrayList) and when I click again the next item (string or drawable) will appear beneath it, pushing it in an upward motion.
UPDATE
I made a Model and an Adapter
Here is the model
public class ModelC1 {
public String C1Name;
public String C1Text;
public int id;
public boolean isSend;
public ModelC1(String C1Name, String C1Text, int id, boolean isSend){
this.id = id;
this.C1Name = C1Name;
this.C1Text = C1Text;
this.isSend = isSend;
}
public int getId(){
return id;
}
public void setId(int id){
this.id = id;
}
public String getC1Name() {
return C1Name;
}
public void setC1Name(String C1Name){
this.C1Name = C1Name;
}
public String getC1Text() {
return C1Text;
}
public void setC1Text (String C1Text){
this.C1Text = C1Text ;
}
public boolean isSend() {
return isSend;
}
public void setIsSend(boolean send){
isSend = send;
}
Here is the Adapter
public class AdapterC1 extends BaseAdapter {
private List<ModelC1> listChat;
private LayoutInflater inflater;
private Context context;
public AdapterC1(List<ModelC1> listChat, Context context){
this.listChat = listChat;
this.context = context;
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return listChat.size();
}
#Override
public Object getItem(int i) {
return listChat.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int i, View convertView, ViewGroup viewGroup) {
View vi = convertView;
if(convertView == null ){
if(listChat.get(i).isSend() == 0)
vi=inflater.inflate(R.layout.list_send,null);
else if ((listChat.get(i).isSend() == 1))
vi=inflater.inflate(R.layout.list_recv,null);
else if ((listChat.get(i).isSend() == 2))
vi=inflater.inflate(R.layout.list_mid,null);
}else{
if(listChat.get(i).isSend() == 0)
vi=inflater.inflate(R.layout.list_send,null);
else if ((listChat.get(i).isSend() == 1))
vi=inflater.inflate(R.layout.list_recv,null);
else if ((listChat.get(i).isSend() == 2))
vi=inflater.inflate(R.layout.list_mid,null);
}
if(listChat.get(i).isSend() !=0 || listChat.get(i).isSend() !=1 || listChat.get(i).isSend() !=2 ){
BubbleTextView bubbleTextView = (BubbleTextView) vi.findViewById(R.id.bubbleChat);
if(bubbleTextView != null)
bubbleTextView.setText(listChat.get(i).C1Text);
TextView nameTextView = (TextView) vi.findViewById(R.id.nameChat);
if(nameTextView != null)
nameTextView.setText(listChat.get(i).C1Name);
}else{
vi=inflater.inflate(R.layout.list_mid,null);
BubbleTextView bubbleTextView = (BubbleTextView) vi.findViewById(R.id.bubbleChat);
bubbleTextView.setText("THE END");
}
return vi;
}
And here is the activity
public class Chat1 extends AppCompatActivity {
private static final String TAG = "Chat1";
private AdapterC1 adapter;
private List<ModelC1> listChat = new ArrayList<>();
private int count = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chat1);
RecyclerView chatContent1 = findViewById(R.id.chatContent1);
}
private ModelC1 setUpMessage(){
Log.d(TAG, "setUpMessage: Exec");
return();
}
///OnClick of the button in the activity_chat1.xml
public void nextClicked1(View view) {
Log.d(TAG, "nextClicked: Is Clicked");
///After the limit of the arraylist is reached
final int limit = 40;
if(count == limit){
Log.d(TAG, "nextClicked: Limit Reached");
Intent i = new Intent(Chat1.this, MainActivity.class);
startActivity(i);
}else{
///Call the list
loadList(null);
}
}
///Load the list of arrays?
public void loadList(View view){
ModelC1 chat = setUpMessage();
listChat.add(chat);
///The ID of the recycleview in the activity_chat1.xml
final RecyclerView recyclerview = findViewById(R.id.chatContent1);
///The adapter
final AdapterC1 adapter = new AdapterC1(listChat, this);
///Make the recyclerview always scroll
///the adapter
///recyclerview.setAdapter(adapter);
}
My questions are now how do I make the ArrayList (containing strings and drawables) and how to link the ArrayList to make it appear one by one when I click on the button ?
As for the ArrayList, will soemthing like that works ?
private List<List<String>> textChat1 = new ArrayList<List<String>>();
ArrayList<String> textChat1 = new ArrayList<String>();
textChat1.add("This is message 1");
textChat1.add("This is message 2");
textChat1.add("This is message 2");
addresses.add(textChat1);
How can I add images and how to say which strings inflate which layout (left, mid or right) ?

You can do your job like this: in your Adapter's getView method ,
#Override
public View getView(int position, View convertView, ViewGroup container) {
if (convertView == null) {
if (position == 1) {
convertView = getLayoutInflater().inflate(R.layout.left, container, false);
} else if (position == 2) {
convertView = getLayoutInflater().inflate(R.layout.mid, container, false);
} else {
convertView = getLayoutInflater().inflate(R.layout.right, container, false);
}
}
//your code here
return convertView;
}
This will do your job, but, I suggest you to use Recyclerview because it's more efficient and better in terms of looks as well as memory management.

Getting focus of EditText inside RecyclerView

I'm implementing an application in which user can store Debit Cards and later they can use it by just entering the CVV number of the same card. I have used RecyclerView for all the items(Debit Cards) stored by the user. Everything is working fine, view is rendering all good and I have used LinearLayoutManager to show Horizontal scroll.
Now the problem which I am facing is whenever I try to enter CVV of any card as soon as I click on it the view gets shifted towards the last item of the list of Stored Cards, So if I'm having three cards stored in my list and I try to enter CVV for the first one the view is shifting directly to the third card but the focus remains on the first cards EditText. I don't know what's going on with the same. I'm sharing some code part for the same.
Setting adapter and defining horizontal scroll :-
recyclerAdapter = new RecyclerStoredCardAdapter(mContext, storedCards);
LinearLayoutManager layoutManager
= new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
storedCardListRecycler.setLayoutManager(layoutManager);
storedCardListRecycler.setVisibility(View.VISIBLE);
storedCardListRecycler.setAdapter(recyclerAdapter);
Sharing the screenshots with this so it will get clear. Any help would be appreciable. Thanks.

I have did this using ListView not with RecyclerView
But you can do with RecyclerView also.

I am giving you my whole class. why? Because it will give you more understanding that how I used it with ListView.
Test it and Let me know. :)
Note
This line of code is very important - getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_MASK_ADJUST);

Not able to reproduce this issue. Let me know if the following code does what you are facing. If not, can provide more feedback if you share you Adapter's Code.
MainActivity.java
public class MainActivity
extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
MyAdapter adapter = new MyAdapter();
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
recyclerView.setAdapter(adapter);
}
}
public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_ite, parent);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
((EditText)((MyViewHolder)holder).mBinding.findViewById(R.id.editText)).setHint(position + " ");
}
#Override
public int getItemCount() {
return 100;
}
public class MyViewHolder extends RecyclerView.ViewHolder {
View mBinding;
public MyViewHolder(View binding) {
super(binding);
this.mBinding = binding;
}
}
}
The 2xml layouts:
<EditText
android:id="#+id/editText"
android:layout_height="200dp"
android:layout_width="300dp"/>
</android.support.v7.widget.CardView>
My main_activity.xml is as follows:
<RelativeLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
</RelativeLayout>
As you can see this is the simplest case. Let me know if I missed anything.

How to replace the baseadapter value and how to stop the pagination loading in android filter screen?

I have worked with the concept of filter that have to filter the job from job list based on skills and some list or there.

final DashListModel dashModel = dashRowList.get(position);
dashHolder = new ViewHolder(convertView);
//Assign the value into screen
dashHolder.dash_company_name.setText(dashModel.getDashCompanyName());
}
the above code for displaying dashboard fragment list.
https://postimg.org/image/nqvp1dud9/ - This link is FilterScreen
By using this image if i filter the job based on the designed UI detail. That should replace into the DashboadFragment list The result should display into the DashBoard Fragment. How can I add pagination on Filter screen the same which have in DashBoardFragment.

Android:Receive Array of Objects and display in listView

Hello to all android folks over there!!

and setVisibiltity(View.VISIBLE)for listview
Put this code here

}
}else{

}

}

you can try this:
this is the adapter class code.
public class CustomTaskHistory extends ArrayAdapter<String> {
private Activity context;
ArrayList<String> listTasks = new ArrayList<String>();
String fetchRefID;
StringBuilder responseOutput;
ProgressDialog progress;
String resultOutput;
public String getFetchRefID() {
return fetchRefID;
}
public void setFetchRefID(String fetchRefID) {
this.fetchRefID = fetchRefID;
}
public CustomTaskHistory(Activity context, ArrayList<String> listTasks) {
super(context, R.layout.content_main, listTasks);
this.context = context;
this.listTasks = listTasks;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_task_history, null, true);
TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName);
LinearLayout linearLayout = (LinearLayout) listViewItem.findViewById(R.id.firstLayout);
//System.out.println("client_id" + _clientID);
//TextView textViewDesc = (TextView) listViewItem.findViewById(R.id.textViewDesc);
//ImageView image = (ImageView) listViewItem.findViewById(R.id.imageView);
if (position % 2 != 0) {
linearLayout.setBackgroundResource(R.color.sky_blue);
} else {
linearLayout.setBackgroundResource(R.color.white);
}
textViewName.setText(listTasks.get(position));
return listViewItem;
}
}
and now in the parent class you must have already added a list view in your xml file so now display code for it is below:
CustomTaskHistory customList = new CustomTaskHistory(TaskHistory.this, task_history_name);
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(customList);
you can also perform any action on clicking cells of listview.If needed code for it is below add just below the above code:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent nextScreen2 = new Intent(getApplicationContext(), SubscribeProgrammes.class);
nextScreen2.putExtra("CLIENT_ID", _clientID);
nextScreen2.putExtra("REFERENCE_ID", reference_IDs.get(i));
startActivity(nextScreen2);
Toast.makeText(getApplicationContext(), "You Clicked " + task_list.get(i), Toast.LENGTH_SHORT).show();
}
});

listview hide on orientation change android

I am using custom list view inside fragment(From Api). on orientation change data is still in array list and also list view get notified but it hides when screen rotates.
here is the code:

You need to load the data into the ListView again. You are binding the ListView to an adapter, you need to do it in onConfigurationChanged() method.

When orientation changes the activity reloads again.So you have to override onConfigurationChanged method.
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
//Your Code Here
}
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
//Your Code Here
}
}

create a directory layout-land in the resources copy the your .xml file there align and set the Edittext and Button according to landscape layout .may be it solved your problem if the listview doest not get enough space to show in landscape layout

In onViewCreated(View view, Bundle savedInstanceState) method above you are setting new empty arraylist every time. So the previous items which are loaded are removed from adapter even though it is retained by setRetainInstance(true)
So you should have a Field that holds the arraylist and pass that field to adapter
private ArrayList<ListRowItem> listItems = new ArrayList<>()
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
if (listAdapter==null) {
listAdapter=new ListAdapter(getActivity(), listItems);//pass the Arraylist here
listView.setAdapter(listAdapter);
listAdapter.notifyDataSetChanged();
}
}
Then in private void listView(String response) method, add items to that listview created above as
listItems = new Gson().fromJson(response, listType);
listAdapter.notifyDataSetChanged();
