[Android] 自定義ListView加入RadioGroup

由於需要做一個測驗類的東西，使用ListView發現Subitem除了文字都不能加，最後快崩潰就只好自己刻一個。

XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    
	<LinearLayout android:orientation="vertical"
	        android:layout_width="wrap_content"
	        android:layout_height="wrap_content">
	 
		<TextView
	         android:id="@+id/booktitle"
	         android:layout_width="wrap_content"
	         android:layout_height="wrap_content"
	         android:layout_marginLeft="20dp"
       		 android:textColor="#000000" />

	    
		<RadioGroup
		     android:id="@+id/bookgroup"
		     android:layout_width="wrap_content"
		     android:layout_height="fill_parent"
		     android:layout_alignParentRight="true"
		     android:layout_alignParentTop="true"
		     android:orientation="horizontal" >
		
		     <RadioButton
		         android:id="@+id/book1"
		         android:layout_width="wrap_content"
		         android:layout_height="wrap_content"
		         android:layout_marginLeft="10dip"
		         android:checked="false"
		         android:text="1" />
		
		     <RadioButton
		         android:id="@+id/book2"
		         android:layout_width="wrap_content"
		         android:layout_height="wrap_content"
		         android:layout_marginLeft="10dip"
		         android:checked="false"
		         android:text="2" />
		     
		     <RadioButton
		         android:id="@+id/book3"
		         android:layout_width="wrap_content"
		         android:layout_height="wrap_content"
		         android:layout_marginLeft="10dip"
		         android:checked="false"
		         android:text="3" />
		     
		     <RadioButton
		         android:id="@+id/book4"
		         android:layout_width="wrap_content"
		         android:layout_height="wrap_content"
		         android:layout_marginLeft="10dip"
		         android:checked="false"
		         android:text="4" />
		     
		     <RadioButton
		         android:id="@+id/book5"
		         android:layout_width="wrap_content"
		         android:layout_height="wrap_content"
		         android:layout_marginLeft="10dip"
		         android:checked="false"
		         android:text="5" />
		 </RadioGroup>
	 
	  </LinearLayout>  
</LinearLayout>

Adapter

package com.example.microsoftapp;
 
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.RadioGroup;
import android.widget.TextView;
 
public class BookAdapter extends BaseAdapter {
 
    private LayoutInflater Bookflater;
    
    CharSequence[] title = null;
    CharSequence[] radiogroup = null;
     
    public BookAdapter(Context ctxt, CharSequence[] title){
    	Bookflater = LayoutInflater.from(ctxt);
        this.title = title;
        this.radiogroup = radiogroup;
    }
     
    @Override
    public int getCount() {
         return title.length;
    }
 
    @Override
    public Object getItem(int position) {
         return title[position];
    }
 
    @Override
    public long getItemId(int position) {
         return position;
    }
 
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
 
    	BookView bookview;
 
        if(convertView == null){
            convertView = Bookflater.inflate(R.layout.booklistview, null);
             
            bookview = new BookView(
            (TextView) convertView.findViewById(R.id.booktitle));
             
            convertView.setTag(bookview);
        }
        else{
        	bookview = (BookView) convertView.getTag();
        }
         
        bookview.title.setText(title[position]);
         
        return convertView;
    }
 
    class BookView{
        TextView title;
        RadioGroup radiogroup;
     
        public BookView(TextView title){
            this.title = title;
            this.radiogroup = radiogroup;
        }
    }
}

使用方法

String[] listtitle ;
CharSequence[] ListTitle = listtitle;  
ListView listview ;
listview.setAdapter(new BookAdapter(this, ListTitle));

但目前RadioGroup還沒實作功能。
