How to insert checkbox on custom listview

How to insert checkbox on custom listview - java

I am trying to add a checkbox in a customized listview but don't know how.
I have the following codes:
ListObject.java
package br.com.eduvm.xurrascalc;
public class ListObject {
private String texto;
private int iconeRid;
public ListObject() {
}
public ListObject(String texto, int iconeRid) {
this.texto = texto;
this.iconeRid = iconeRid;
}
public int getIconeRid() {
return iconeRid;
}
public void setIconeRid(int iconeRid) {
this.iconeRid = iconeRid;
}
public String getTexto() {
return texto;
}
public void setTexto(String texto) {
this.texto = texto;
}
}
ListAdapter.java
package br.com.eduvm.xurrascalc;
import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.ImageView;
import android.widget.TextView;
public class ListAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<ListObject> itens;
public ListAdapter(Context context, ArrayList<ListObject> itens) {
// Itens que preencheram o listview
this.itens = itens;
// responsavel por pegar o Layout do item.
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return itens.size();
}
public ListObject getItem(int position) {
return itens.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View view, ViewGroup parent) {
ListObject item = itens.get(position);
view = mInflater.inflate(R.layout.itens_lista, null);
((TextView) view.findViewById(R.id.text)).setText(item.getTexto());
((ImageView) view.findViewById(R.id.imagemview)).setImageResource(item.getIconeRid());
return view;
}
}
List.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:padding="5sp" >
<ImageView
android:id="#+id/imagemview"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
<TextView
android:id="#+id/text"

android:layout_height="match_parent"
android:layout_marginLeft="5sp"
android:gravity="center_vertical"

How could I do to insert a checkbox in the items in this list?

This would be the layout for each individual row in your list
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<CheckBox
android:id="#+id/lstChkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/lstText"
android:textSize="30px"
android:layout_weight="1" />
<ImageView
android:id="#+id/listImage"
android:layout_height="wrap_content"
android:layout_width="wrap_content" />
You main list activity layout will look something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"
android:choiceMode="multipleChoice"
/>
Your class which extends BaseAdapter getView method will somethings like this:
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder vHolder = null;
if (convertView != null)
vHolder = (ViewHolder) convertView.getTag(); // convertView is been recycled
else {
convertView = (View) mInflater.inflate(R.layout.list_item, null); // Set content of new View with list_item.xml
vHolder = new ViewHolder();
vHolder.checkBox = ((CheckBox) convertView.findViewById(R.id.lstChkbox)); // Getting pointers
vHolder.textView = ((TextView) convertView.findViewById(R.id.lstText));
vHolder.imageView = ((ImageView) convertView.findViewById(R.id.listImage));
vHolder.checkBox.setOnCheckedChangeListener(this); // Setting Listeners
convertView.setTag(vHolder);
}
vHolder.checkBox.setId(position); // This is part of the Adapter APi
vHolder.textView.setId(position); // Do not delete !!!
vHolder.imageView.setId(position);
if (mItems.get(position).getChecked()) { // Setting parameters for the View from our mItems list
vHolder.checkBox.setChecked(true);
} else {
vHolder.checkBox.setChecked(false);
}
vHolder.textView.setText(mItems.get(position).getText());
vHolder.imageView.setImageDrawable(mItems.get(position).getmImage());
return convertView;
}
public static class ViewHolder {
CheckBox checkBox;
TextView textView;
ImageView imageView;
}
/*
* Ok for this test but Toast are going to show every time the row comes into View
*/
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
Log.d(TAG, "Checked");
int position = buttonView.getId();
if (isChecked) {
mItems.get(position).setChecked(true);
Toast.makeText(context, mItems.get(position).getText(), Toast.LENGTH_LONG).show();
} else {
mItems.get(buttonView.getId()).setChecked(false);
}
}

Just add a checkbox to the layout itens_lista.xml.
Just adding a checkbox is easy. Do you want to do anything more to ti.

Add a CheckBox View to your custom row layout.

How to make custom adapter?

I'm trying to make custom adapter for my small app, I got stuck in filling my rows with data, I can't find a good tutorial for that. I know how to use Simple Adapter and Array Adapter, but custom ones have some trouble.
I don't know how to implement it, and the online articles confused me, Please help me with the logic and what steps should I do implement.
package com.example.administrator.healthyfood;

Hope this is enough for you.

You can create a simple Adapter class using these simple steps
make a java class
public class Wallet_Adapter extends RecyclerView.Adapter<Wallet_Adapter.ViewHolder>
{
LayoutInflater inflater;
List<Wallet_Model> modelclasslists;
public Wallet_Adapter(Context ctx, List<Wallet_Model> modelclasslists)
{
this.inflater=LayoutInflater.from(ctx);
this.modelclasslists=modelclasslists;
}
#NonNull
#Override
public Wallet_Adapter.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view=inflater.inflate(R.layout.layout_wallet,parent,false);
return new Wallet_Adapter.ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull Wallet_Adapter.ViewHolder holder, int position) {
holder.date.setText(modelclasslists.get(position).getDate());
holder.amount.setText(modelclasslists.get(position).getAmount());
holder.description.setText(modelclasslists.get(position).getDescription());
holder.type.setText(modelclasslists.get(position).getType());
}
#Override
public int getItemCount() {return modelclasslists.size(); }
public class ViewHolder extends RecyclerView.ViewHolder
{
TextView date,amount,description,type;
public ViewHolder(#NonNull View itemView)
{
super(itemView);
date=itemView.findViewById(R.id.dateans);
amount=itemView.findViewById(R.id.amountans);
description=itemView.findViewById(R.id.descriptionans);
type=itemView.findViewById(R.id.typeans);
}
}
}

Spinner's style is changed once i open it for the second

I am developing an app where I show a dropdownlist using a spinner.
I used a custom adapter, here is the code:
public class DemandeCongeAdapter extends BaseAdapter {
public static final String TAG = "DemandeCongeAdapter";
private final Context mContext;
private List<DemandeCongeType> mData;
protected LayoutInflater mInflater;
public DemandeCongeAdapter(Context mContext, List<DemandeCongeType> mData) {
this.mContext = mContext;
this.mData = mData;
this.mInflater = LayoutInflater.from(mContext);
}
static class ViewHolder {
public ViewHolder(View v) {
typedeDemandeName = (TextView) v.findViewById(R.id.type_demande_name);
}
protected final TextView typedeDemandeName;
}
#Override
public int getCount() {
return mData.size();
}
#Override
public DemandeCongeType getItem(int position) {
return mData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.layout_create_demande_conge_custom_spinner, parent, false);
viewHolder = new ViewHolder(convertView);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
if (position != 0) {
DemandeCongeType item = getItem(position);
String name = item.getTypdeDemandeName() == null ? "" : item.getTypdeDemandeName();
viewHolder.typedeDemandeName.setText(name);
}
return convertView;
}
}
And for the activity code, here is it:
private List<DemandeCongeType> congeTypes;
private DemandeCongeAdapter spinnerCongeTypeArrayAdapter;
congeTypes.addAll(new ArrayList<>((List<DemandeCongeType>) responseBody));
congeTypes.add(0, new DemandeCongeType());
spinnerCongeTypeArrayAdapter = new
DemandeCongeAdapter(DemandeCongeNewActivity.this, congeTypes);
congeTypeSpinner.setAdapter(spinnerCongeTypeArrayAdapter);
congeTypeSpinner.setSelection(Adapter.NO_SELECTION, false);
Everything works fine, but when I select the spinner for the first time, it shows the list correctly like this:
Once I click outside the spinner and I click for the second time on the spinner, I got it like this:
So I can't the find the problem, please if anyone can help me with that.
Here is the XML code:
<Spinner
android:id="#+id/spinner_type_conge"
fontPath="fonts/light.otf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:background="#null"
android:dropDownWidth="match_parent"
android:ellipsize="end"
android:lines="1"
android:paddingRight="2dp"
android:spinnerMode="dropdown"
android:textSize="13sp" />
And for the spinner item xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/type_demande_name"
fontPath="fonts/light.otf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:lines="1"
android:padding="10dp"
android:textColor="#color/annuaire_hint_color"
android:textSize="13sp" />

Try This way i have use this in my Application.
XML Design Code.
Spinner set in your Activity
<Spinner
android:id="#+id/sp_pen_Category"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:background="#android:color/transparent"
android:padding="#dimen/margin_10" />
This file XML File sp_list.xml
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:ellipsize="marquee"
android:padding="15dp"
android:singleLine="true"
android:textColor="#color/black"
android:textSize="#dimen/sub_title">
</CheckedTextView>
This file XML File sp_items.xml
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:ellipsize="marquee"
android:singleLine="true"
android:textColor="#color/black">
</CheckedTextView>
This is Java code when you fill spinner.
ArrayAdapter<String> adp_sp = new ArrayAdapter<String>(Activity.this, R.layout.sp_items, arr_spinner);
adp_sp.setDropDownViewResource(R.layout.sp_list);
sp_pen_Category.setAdapter(adp_sp);

Listview OnItemClick Event

I have following code that should:
listView = (ListView) findViewById(R.id.listview_github_entries);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
}
});
This is what I load into the ListView:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_item"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp"
android:orientation="horizontal"
android:clickable="true">
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#mipmap/github_icon"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/github_name"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/github_url"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
Here is the Adapter :
public class GithubEntryAdapter extends ArrayAdapter<GithubEntry>{
public GithubEntryAdapter(Activity context, ArrayList<GithubEntry> githubEntries){
super(context, 0, githubEntries);
}
public View getView(int position, View convertView, ViewGroup parent){
View listItemView = convertView;
if (listItemView == null){
listItemView = LayoutInflater.from(getContext()).inflate(
R.layout.list_item, parent, false);
}
GithubEntry currentGithubEntry = getItem(position);
TextView github_url = (TextView) listItemView.findViewById(R.id.github_url);
github_url.setText(currentGithubEntry.getGithub_url());
TextView github_name = (TextView) listItemView.findViewById(R.id.github_name);
github_name.setText(currentGithubEntry.getGithub_name());
return listItemView;
}
}
This is not working for me. Im no quit sure where I should place this code. Can I place this in the onCreate? If not where should I move it? I completly new in Android and I have also not much experience in Java.

Here is what i did for you..
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.Toast;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
private ListView listView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.listview_github_entries);
listView.setAdapter(new GithubEntryAdapter(MainActivity.this, getList()));
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
TextView github_url_tv = view.findViewById(R.id.github_url);
String url_text= github_url_tv.getText().toString();
Toast.makeText(MainActivity.this, url_text", Toast.LENGTH_LONG).show();
}
});
}
private ArrayList<GithubEntry> getList() {
ArrayList<GithubEntry> githubEntries = new ArrayList<>();
GithubEntry githubEntry = new GithubEntry();
githubEntry.setGithub_name("Name");
githubEntry.setGithub_url("url");
GithubEntry githubEntry1 = new GithubEntry();
githubEntry1.setGithub_name("Name");
githubEntry1.setGithub_url("url");
GithubEntry githubEntry2 = new GithubEntry();
githubEntry2.setGithub_name("Name");
githubEntry2.setGithub_url("url");
githubEntries.add(githubEntry);
githubEntries.add(githubEntry1);
githubEntries.add(githubEntry2);
return githubEntries;
}
}
Here is adapter
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import java.util.ArrayList;

githubEntries){
super(context, 0, githubEntries);
}
public View getView(int position, View convertView, ViewGroup parent){
View listItemView = convertView;
if (listItemView == null){
listItemView = LayoutInflater.from(getContext()).inflate(
R.layout.list_item, parent, false);
}
GithubEntry currentGithubEntry = getItem(position);
TextView github_url = (TextView) listItemView.findViewById(R.id.github_url);
github_url.setText(currentGithubEntry.getGithub_url());
TextView github_name = (TextView) listItemView.findViewById(R.id.github_name);
github_name.setText(currentGithubEntry.getGithub_name());
return listItemView;
}
}
here is POJO(plan java object) class
class GithubEntry {
private String Github_url;
private String Github_name;
public String getGithub_url() {
return Github_url;
}
public void setGithub_url(String github_url) {
Github_url = github_url;
}
public String getGithub_name() {
return Github_name;
}
public void setGithub_name(String github_name) {
Github_name = github_name;
}
}
and here is list_item
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_item"
android:layout_width="match_parent"

</LinearLayout>

If mean that the OnItemClickListeneter not working, then you need to implement a custom adapter by extending ArrayAdater to serve you custom row, And in the custom adapter you can use a callback interface or implement a listener on the view it self See the example.

I think you want to display the list of values here. You should write it inside onCreate because onCreate is a method where you method starts and run. So, Put it inside onCreate. For more correct answer please explain everything.

I think you add an Icon in your GroupView. Then, during getGroupView(), you check how many child view that group have and decide whether to display the "Empty" icon
Group View Layout:
<LinearLayout>
<LinearLayout
...>
<ImageView
.../>
<TextView
... />
<ImageView>
<!-- IMAGEVIEW ICON TO SHOW THIS GROUP IS EMPTY -->
android:id="#+id/empty_group_icon"
android:visibility="invisible"
</ImageView>
</LinearLayout>
</LinearLayout>
And inside your getGroupView()
#Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
...
if(getChildrenCount(groupPosition) > 0)
convertView.findViewById(R.id.empty_group_icon).setVisibility(View.INVISIBLE);
else
convertView.findViewById(R.id.empty_group_icon).setVisibility(View.VISIBLE);
return convertView;
}

Android Grid View with Image and Text

I need to show text below every image in grid view. I have been able to put the images in grid view but how to put text below it? Below I'm posting the code snippets.
fragment_facility_grid.xml
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/grid_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="auto_fit"
android:columnWidth="90dp"
android:horizontalSpacing="10dp"
android:verticalSpacing="10dp"
android:gravity="center"
android:stretchMode="columnWidth" >
</GridView>
FacilityAdapter.class
package com.androidbelieve.HIT_APP;
/**
* Created by Akash on 2/13/2016.
*/
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.TextView;
public class FacilityAdapter extends BaseAdapter {
private Context mContext;
// Keep all Images in array
public Integer[] mThumbIds = {
R.drawable.bank, R.drawable.bus,
R.drawable.girlshostel , R.drawable.guesthouse,
R.drawable.gym , R.drawable.library,R.drawable.sports
};
public String[] mThumbNames = {
"Bank", "Bus Service","Guest House", "GYM","Fac1","Fac2"
};
// Constructor
public FacilityAdapter(Context c){
mContext = c;
}
#Override
public int getCount() {
return mThumbIds.length;
}
#Override
public Object getItem(int position) {
return mThumbIds[position];
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View gridView;
gridView = new View(mContext);
ImageView imageView = new ImageView(mContext);
imageView.setImageResource(mThumbIds[position]);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setLayoutParams(new GridView.LayoutParams(300, 300));
return imageView;
}
}
Thank You

I would rather suggest that instead of creating ImageView dynamically at run time and return that from your getView() method, you should create an xml for your each of the list items. Below is the sample xml with ImageView and TextView
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop"/>
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:gravity="center"/>
</LinearLayout>
Also you should follow ViewHolder Patternto make your GridView memory efficient. Your getView() method will look alike this
#Override
public View getView(int arg0, View convertView, ViewGroup arg2) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = layoutInflater.inflate(R.layout.yourxml,
null);
holder.textview= (TextView) convertView.findViewById(R.id.text);
holder.imageview= (ImageView) convertView.findViewById(R.id.image);
holder.imageView.getLayoutParams().width = yourImageWidth;
holder.imageView.getLayoutParams().height = yourImageHeight;
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.imageView.setImageResource(mThumbIds[position]);
holder.textview.setText(mThumbNames[position]);
return convertView;
}
static class ViewHolder {
ImageView imageView;
TextView textView;
}

Try to extend this:
SimpleAdapter
or use it by default like:
private Context mContext;
// Keep all Images in array
public Integer[] mThumbIds = {
R.drawable.bank, R.drawable.bus,
R.drawable.girlshostel , R.drawable.guesthouse,
R.drawable.gym , R.drawable.library,R.drawable.sports
};
public String[] mThumbNames = {"Bank", "Bus Service","Guest House", "GYM","Fac1","Fac2"};
Simple adapter= new SimpleAdapter(mContext, List<?> your_list, R.layout.your_layout_file, from, to);
You also have to make a layout file and define how the image and text you would like to look for each gridview item like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="#+id/this_image_id_have_to_be_used_in_your_to_array"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop"/>
<TextView
android:id="#+id/this_text_id_have_to_be_used_in_your_to_array"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:gravity="center"/>
</LinearLayout>
Hope it helps!!!
