사용자 정의 라디오 버튼이있는 Android 사용자 정의 목록보기

Question

사용자 정의 라디오 버튼 (단일 선택 항목 옵션)을 사용하여 사용자 정의 listview (한 이미지 당 하나의 텍스트 &)를 수행하려고합니다.

내 코드 :

이

listview.setAdapter(new myAdapter(getApplicationContext(), 
        R.layout.mycontent, text)); 

내 어댑터 클래스 :

public class myMessageAdapter extends ArrayAdapter<String> { 
private LayoutInflater mInflater; 

private String[] mText = null; 

long id; 
private int mViewResourceId; 

public myMessageAdapter(Context ctx, int viewResourceId, 
     ArrayList<String> textList) { 

    super(ctx, viewResourceId); 

    mInflater = (LayoutInflater) ctx 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    String[] message = textList.toArray(new String[textList.size()]); 

    mText = message; 

    mViewResourceId = viewResourceId; 
} 

@Override 
public int getCount() { 
    return mText .length; 
} 

@Override 
public String getItem(int position) { 
    return mText [position]; 
} 

@Override 
public long getItemId(int position) { 
    return 0; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    convertView = mInflater.inflate(mViewResourceId, null); 

    TextView MESSAGE = (TextView) convertView.findViewById(R.id.message); 

    id = getItemId(position); 

    MESSAGE.setText(mText [position]); 
    return convertView; 
} 
} 

내 출력 목록 항목이 있어야한다 : 당신의 getView 팽창 지정 레이아웃에서

 <radioButton> <Text> <Image>.Single choice selection.How could i do that? 

Answer 1

public View getView(int arg0, View arg1, ViewGroup arg2) { 
    ViewHolder vh; 
    vh= new ViewHolder(); 

    if(arg1==null) 
    { 
     arg1=mInflater.inflate(R.layout.customlistview, arg2,false); 
     vh.iv1= (ImageView)arg1.findViewById(R.id.ivs); 
     vh.rb= (RadioButton) arg1.findViewById(R.id.radioButton1); 
     vh.tv= (TextView)arg1.findViewById(R.id.textView1); 

    } 
    else 
    { 
    arg1.setTag(vh); 
    } 
      //set data to textview, radiobutton and imageview. 
    return arg1; 
} 

    static class ViewHolder 
    { 
    TextView tv; 
    RadioButton rb; 
    ImageView iv1; 
    } 

customlistview.xml. 각 행의 사용자 정의 레이아웃.

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

<RadioButton

    <LinearLayout 
     android:layout_width="fill_parent"

     <RadioButton 
      android:id="@+id/radioButton1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:button="@drawable/button_radio" 
      android:paddingLeft="60dip" 
      android:text="RadioButton" /> 

     <TextView 
      android:id="@+id/textView1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="TextView" /> 

     <Button 
      android:id="@+id/button1"
