Custom Single Choice Listview

Custom Single choice ListView

I've been searching for an answer to this problem all morning, and the most useful thing I've found so far is this article.

While I haven't implemented the solution it suggests yet, it sounds like it's on the right track.

Basically, the single-choice ListView expects the widgets you provide it with to implement the Checkable interface. LinearLayout and others don't. So you need to create a custom layout that inherits LinearLayout (or whatever layout you want to use for your items) and implements the necessary interface.

Custom Listview with CheckBox single selection

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..

Custom ListView with RadioButton single choice

Try like this :

public class CheckedLinearLayout extends RelativeLayout implements
    Checkable {

private boolean isChecked;
private List<Checkable> checkableViews;

public CheckedLinearLayout (Context context, AttributeSet attrs,
        int defStyle) {
    super(context, attrs, defStyle);

Custom ListView with single choice selection

I also came across the same problem, I used RelativeLayout

Try like this

public class CheckedLinearLayout extends RelativeLayout implements
        Checkable {

    private boolean isChecked;
    private List<Checkable> checkableViews;

    public CheckedLinearLayout (Context context, AttributeSet attrs,
            int defStyle) {
        super(context, attrs, defStyle);
        initialise(attrs);
    }

    public CheckedLinearLayout (Context context, AttributeSet attrs) {
        super(context, attrs);
        initialise(attrs);
    }

    public CheckedLinearLayout (Context context, int checkableId) {
        super(context);
        initialise(null);
    }

    public boolean isChecked() {
        return isChecked;
    }

    public void setChecked(boolean isChecked) {
        this.isChecked = isChecked;
        for (Checkable c : checkableViews) {
            c.setChecked(isChecked);
        }
    }
    public void toggle() {
        this.isChecked = !this.isChecked;
        for (Checkable c : checkableViews) {
            c.toggle();
        }
    }

    @Override
    protected void onFinishInflate() {
        super.onFinishInflate();

        final int childCount = this.getChildCount();
        for (int i = 0; i < childCount; ++i) {
            findCheckableChildren(this.getChildAt(i));
        }
    }

    /**
     * Read the custom XML attributes
     */
    private void initialise(AttributeSet attrs) {
        this.isChecked = false;
        this.checkableViews = new ArrayList<Checkable>(5);
    }

    /**
     * Add to our checkable list all the children of the view that implement the
     * interface Checkable
     */
    private void findCheckableChildren(View v) {
        if (v instanceof Checkable) {
            this.checkableViews.add((Checkable) v);
        }

        if (v instanceof ViewGroup) {
            final ViewGroup vg = (ViewGroup) v;
            final int childCount = vg.getChildCount();
            for (int i = 0; i < childCount; ++i) {
                findCheckableChildren(vg.getChildAt(i));
            }
        }
    }
}
