Android also the option Multiple Select ListView

Android also the option Multiple Select ListView - You might have noticed that Samsung is one of the only brands to opt against a 'notch' at the top like the iPhone X. We're not quite sure why others are so keen to copy Apple and even though some provide a way to switch the feature off, we like the fact Samsung has stuck to the regular style here. add a white pixel, well we have collected a lot of data from the field directly and from many other blogs so very complete his discussion here about Android also the option Multiple Select ListView, on this blog we also have to provide the latest automotive information from all the brands associated with the automobile. ok please continue reading:

Android Multiple Choice ListView Using Custom Adapter.This listview you can use when you send sms to more than one friend or any notification to your friends.


So using Custom Adapeter we have to create row.xml layout which has checkbox.

row.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="@android:color/white" >

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:layout_margin="5dp"
        android:layout_toLeftOf="@+id/checkbox"
        android:text="title"
        android:textColor="@android:color/black"
        android:textSize="20dp"
        android:textStyle="bold" >
    </TextView>

    <CheckBox
        android:id="@+id/checkbox"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_marginRight="10dip"
        android:background="@drawable/chk"
        android:button="@null"
        android:focusable="false"
        android:focusableInTouchMode="false" >
    </CheckBox>
</RelativeLayout>

 Now Using Adapter we can bind data to ListView.But we need to learn easy way to bind data with custom ListView and also hadle CheckBox Listener For Each Row.

So here i have RSS Feed to get data from web and then i add it in List<NameBean>.NameBean is bean class which contains value of Rss Feed Element and we have to maintain one boolean for checkbox state either checked or not.And generate Getters And Setters.

NameBean.java

public class NameBean {

private String name;
private boolean selected;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public boolean isSelected() {
return selected;
}

public void setSelected(boolean selected) {
this.selected = selected;
}

}

Now when you get data through XML Parsing you have to create Object of NameBean and you can set data and add Object to List.


for (int temp = 0; temp < nList.getLength(); temp++) {

Node nNode = nList.item(temp);

                  if (nNode.getNodeType() == Node.ELEMENT_NODE) {

   Element eElement = (Element) nNode;

    NameBean objItem = new NameBean();

   objItem.setName(getTagValue("name", eElement));
                 
   list.add(objItem);

}
}



Now list  is fill up with NameBean Objects.And you can retrive data in Adapter so when you set ListView you just retrieve data in getView(...) method of Adapter.

In getView(...) method put checkBox listener to listen checkbox is check or not, if its checked then set boolean true for that object of NameBean And if its not checked then setSelected false to Namebean object.

So when you start this example in listview and its get data from webservice and bind data to listview using NameAdapter Class.



NameAdapter.java


import java.util.List;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.TextView;

public class NamesAdapter extends ArrayAdapter<NameBean> {

private List<NameBean> list;
private LayoutInflater inflator;

public NamesAdapter(Activity context, List<NameBean> list) {
super(context, R.layout.row, list);
this.list = list;
inflator = context.getLayoutInflater();
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

ViewHolder holder = null;
if (convertView == null) {
convertView = inflator.inflate(R.layout.row, null);
holder = new ViewHolder();
holder.title = (TextView) convertView.findViewById(R.id.title);
holder.chk = (CheckBox) convertView.findViewById(R.id.checkbox);
holder.chk
.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton view,
boolean isChecked) {
int getPosition = (Integer) view.getTag();
list.get(getPosition).setSelected(view.isChecked());

}
});
convertView.setTag(holder);
convertView.setTag(R.id.title, holder.title);
convertView.setTag(R.id.checkbox, holder.chk);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.chk.setTag(position);

holder.title.setText(list.get(position).getName());
holder.chk.setChecked(list.get(position).isSelected());

return convertView;
}

static class ViewHolder {
protected TextView title;
protected CheckBox chk;
}
}


When your listView is bind with data you can see checkbox in row with name and now you can get Selected name using NameBean Object and you can retrieve it from list.


                // Retrive Data from list Using for-each loop
                StringBuffer sb = new StringBuffer();
for (NameBean bean : items) {

if (bean.isSelected()) {
sb.append(bean.getName());
sb.append(",");
}
}



Now you get All Selected name from ListView.So its so easy to write Multiple Choice ListView in Android.
