Custom Listview with CheckBox single selection
Solution 1
Here is what i would do if i need to select only single item at a time.
Home.java (Activity)
package com.lvcheck.activities;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
public class Home extends Activity
{
private ListView lvCheckBox;
private Button btnCheckAll, btnClearALl;
private String[] arr = {"One", "Two", "Three", "Four", "Five", "Six"};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnCheckAll = (Button)findViewById(R.id.btnCheckAll);
btnClearALl = (Button)findViewById(R.id.btnClearAll);
lvCheckBox = (ListView)findViewById(R.id.lvCheckBox);
lvCheckBox.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
lvCheckBox.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice, arr));
btnCheckAll.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
for(int i=0 ; i < lvCheckBox.getAdapter().getCount(); i++)
{
lvCheckBox.setItemChecked(i, true);
}
}
});
btnClearALl.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
for(int i=0 ; i < lvCheckBox.getAdapter().getCount(); i++)
{
lvCheckBox.setItemChecked(i, false);
}
}
});
}
}
and my (main.xml) XML file should like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="fill_parent"
android:orientation="horizontal"
android:gravity="center"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:text="Check All"
android:layout_marginRight="7dip"
android:id="@+id/btnCheckAll"
android:layout_height="wrap_content">
</Button>
<Button
android:layout_width="wrap_content"
android:text="Clear All"
android:id="@+id/btnClearAll"
android:layout_height="wrap_content">
</Button>
</LinearLayout>
<ListView
android:layout_width="fill_parent"
android:id="@+id/lvCheckBox"
android:fadingEdge="none"
android:cacheColorHint="@null"
android:layout_height="fill_parent">
</ListView>
</LinearLayout>
so the output will be like this way..

You can use CheckBox
in your adapter class. Try this.
@Override
public View getView(final int position, View convertView,
ViewGroup parent) {
// TODO Auto-generated method stub
if (convertView == null) {
inflater = LayoutInflater.from(adapterContext);
convertView = inflater.inflate(R.layout.view, null);
final ViewHolder viewHolder = new ViewHolder();
viewHolder.name = (TextView) convertView.findViewById(R.id.txtName);
viewHolder.checkBox = (CheckBox) convertView.findViewById(R.id.checkBox1);
convertView.setTag(viewHolder);
}
final ViewHolder holder = (ViewHolder) convertView.getTag();
holder.name.setText(collectContactList.get(position).getName());
holder.checkBox.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
CheckBox cb = (CheckBox) v;
if (cb.isChecked() == true)
{
// Here you will get list of checked item.
}
else
{
// Here you will get list of unchecked item.
}
}
});
Hope this will help you.

Here I am creating custom listview with checkbox / RadioButton. I got this but I need the single selection for that.
I try using this
lstvw.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
but it not works for me. Is there any other solutions for that then please let me know.main.java
private ImageAdapter adapter; private static String month[] = {"January","February","March","April","May", "June","July","August","September", "October","November","December"}; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ListView lstvw = (ListView) findViewById(R.id.listView); adapter = new ImageAdapter(this, month); lstvw.setAdapter(adapter); lstvw.setChoiceMode(ListView.CHOICE_MODE_SINGLE); lstvw.setOnItemClickListener(this); }
I have no idea for the how to add code for the checkbox into the adapter class.please check the adapter class as below.
ImageAdapter.class
public class ImageAdapter extends BaseAdapter{ public String title[]; public String description[]; public Activity context; public LayoutInflater inflater; public ImageAdapter(Activity context,String[] title) { super(); this.context = context; this.title = title; this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { // TODO Auto-generated method stub return title.length; } @Override public Object getItem(int position) { // TODO Auto-generated method stub return null; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return 0; } public static class ViewHolder { TextView txtViewTitle; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub ViewHolder holder; if(convertView==null) { holder = new ViewHolder(); convertView = inflater.inflate(R.layout.listitem, null); holder.txtViewTitle = (TextView) convertView.findViewById(R.id.lstvw_textView); convertView.setTag(holder); } else holder=(ViewHolder)convertView.getTag(); holder.txtViewTitle.setText(title[position]); return convertView; } }
EDIT:
Listitem.xml
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" > <TextView android:id="@+id/lstvw_textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_toLeftOf="@+id/itemCheckBox" android:padding="8dp" android:text="hello world" /> <CheckBox android:id="@+id/itemCheckBox" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:gravity="right" />
