Question

I want to make a custom List View having Two TextViews and a radio Button in a single row. And on listitem click the radio button state should be toggle. I cannot use Simple Adapter here.

I have already asked that question Single choice ListView custom Row Layout but don’t find any satisfactory solution.

What I am currently doing is I am using simple_list_item_single_choice and putting data of both TextViews in a single one separated by some white spaces. But here it is getting worse (shown in the image below).

What I want is to fix the location of size and price and make list view as single choice.

XML Layout for the list can be something like:

**<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/tv_size"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        android:textSize="15sp"
        android:width="200dp" />

    <TextView
        android:id="@+id/tv_price"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        android:textSize="15sp"
        android:width="70dp" />

    <RadioButton
        android:id="@+id/radioButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>**

How to make custom adapter for that?

Answer 1

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.
