列表视图用复选框

我想表明与复选框列表视图像列表视图用复选框

  checkbox listitem1 
      checkbox listitem2 
      checkbox listitem3 
        . 
        . 
        . 
        .

如果点击列表视图中的任何列表项，则相应的复选框选中将是真实的。我想下面的代码

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 
<CheckBox android:text="" 
    android:id="@+id/list_checkbox" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:checked="false" 
    ></CheckBox> 
<TextView 
android:id="@+id/songname" 
android:layout_height="wrap_content" 
android:layout_width="wrap_content" 
android:layout_marginTop="10px" 
android:layout_marginLeft="60px"/> 
<TextView 
android:id="@+id/artist" 
android:layout_height="wrap_content" 
android:layout_width="wrap_content" 
android:layout_marginTop="30px" 
android:layout_marginLeft="60px"/> 
</RelativeLayout>

类文件

list.setOnItemClickListener(this); 
list.setAdapter(new EfficientAdapter(this)); 

private static class EfficientAdapter extends BaseAdapter 
    { 
     private LayoutInflater mInflater; 

     public EfficientAdapter(Context context) 
     { 
     mInflater = LayoutInflater.from(context); 
     } 

     public int getCount() 
     { 
     return title.length; 
     } 

     public Object getItem(int position) 
     { 
     return position; 
     } 

     public long getItemId(int position) 
     { 
      return position; 
     } 

     public View getView(int position, View convertView, ViewGroup parent) 
     { 
     ViewHolder holder; 
     if (convertView == null) 
     { 
     convertView = mInflater.inflate(R.layout.selectsongs, null); 
     holder = new ViewHolder(); 

     holder.title = (TextView) convertView.findViewById(R.id.songname); 
     holder.artist = (TextView) convertView.findViewById(R.id.artist); 
     holder.check = (CheckBox) convertView.findViewById(R.id.list_checkbox);  
     convertView.setTag(holder); 
     } 
     else 
     { 
     holder = (ViewHolder) convertView.getTag(); 
     } 

     holder.title.setText(title[position]); 
     holder.artist.setText(artist[position]); 

     return convertView; 
     } 

     static class ViewHolder 
     { 
     TextView title,artist; 

     CheckBox check; 

     } 
     } 
    @Override 
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) { 
    // TODO Auto-generated method stub 
    Log.e("name",title[position]); 

}

但在这对ListView中OnClickItemClickListener不工作。当我点击不在listview中的listitem上的复选框时，复选框可选。所以请告诉我如何显示列表视图与复选框和listitem复选框checkable是真实的，当我点击listitem。

最好的问候。

在此先感谢

其更好地完成使用ChechBoxPreference名单。

使用偏好的主要优点是您不需要编写代码来保存该值，并且您可以轻松地在任何活动中获取该值。该值作为密钥对值存储在android首选项中。您可以使用'KeyName'来引用该值。

我有同样的问题。我刚才固定它前2天：

在：公共查看getView2小时努力

cb =(CheckBox)row.findViewById(R.id.CheckBox01); 
      cb.setChecked(etat[position]); 

      final int xt=position; 

      cb.setOnCheckedChangeListener(new OnCheckedChangeListener() { 
      @Override 
      public void onCheckedChanged(CompoundButton arg0, boolean arg1) { 
       if(arg0.isChecked()) 
       {   
        etat[xt]=true; 
        //Update the state of Checkbox to the: "tabEtat" 
        Etat.getInstance().setAddIdEtat(String.valueOf(xt)); 
         }       
       } 
       else 
       { 
        //Update the state of Checkbox to the : "tabEtat" 
        Etat.getInstance().setDeleteIdEtat(String.valueOf(xt)); 
         }       
       } 
      } 
     });

后，我得到解决它。

/** 
*This is Adapter class 
*/ 
    public class CustomListAdapter extends BaseAdapter { 

     private String[] stringArray; 
     private Context mContext; 
     private LayoutInflater inflator; 
     int checkbox; 
     /** 
     * 
     * @param context 
     * @param stringArray 
     */ 
     public CustomListAdapter(Context context, String[] stringArray) 
     { 
      this.mContext=context; 
      this.stringArray=stringArray; 
      this.inflator= (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     } 

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

     @Override 
     public Object getItem(int position) 
     { 
      return position; 
     } 

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

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

      final MainListHolder mHolder; 
      View v = convertView; 
      if (convertView == null) 
      { 
       mHolder = new MainListHolder(); 
       v = inflator.inflate(android.R.layout.simple_list_item_multiple_choice, null); 
       mHolder.txt=(CheckedTextView) v.findViewById(android.R.id.text1); 
       v.setTag(mHolder); 
      } 
      else 
      { 
       mHolder = (MainListHolder) v.getTag(); 
      } 
      mHolder.txt.setText(stringArray[position]); 
      mHolder.txt.setTextSize(12); 
      mHolder.txt.setTextColor(Color.YELLOW); 

     /** 
     * When checkbox image is set By setImageFromResourceCheckBox(int id) method...Otherwise it takes default 
     */ 
      if(checkbox!=0) 
       mHolder.txt.setCheckMarkDrawable(R.drawable.android_button); 

      mHolder.txt.setPadding(5, 5, 5, 5); 
      return v; 
     } 
     class MainListHolder 
     { 
      private CheckedTextView txt; 

     } 
     /*** 
     * Setting Image for Checkbox 
     * @param id 
     * 
     */ 
     public void setImageFromResourceCheckBox(int id) 
     { 
      this.checkbox=id; 
     } 


    }

而且Activity类应该是这样的。

public class MyActivity extends ListActivity implements OnItemClickListener { 


    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 



     CustomListAdapter c=new CustomListAdapter(this,GENRES); 
     // c.setImageForCheckBox(R.drawable.android_button);//Image for checkbox 
     setListAdapter(c); 

     final ListView listView = getListView(); 
     listView.setItemsCanFocus(false); 
     // listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);// For single mOde 

     listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); 
     listView.setItemChecked(2, true); 

     listView.setOnItemClickListener(this); 
    } 


    private static String[] GENRES = new String[] { 
     "Action", "Adventure", "Animation", "Children", "Comedy", "Documentary", "Drama", 
     "Foreign", "History", "Independent", "Romance", "Sci-Fi", "Television", "Thriller" 
    }; 
    @Override 
    public void onItemClick(AdapterView<?> adapter, View arg1, int arg2, long arg3) 
    { 

    SparseBooleanArray sp=getListView().getCheckedItemPositions(); 

    String str=""; 
    for(int i=0;i<sp.size();i++) 
    { 
     str+=GENRES[sp.keyAt(i)]+","; 
    } 
    Toast.makeText(this, ""+str, Toast.LENGTH_SHORT).show(); 

    } 


}
