1. 记录所有复选框的状态。

   
   
   • 数据类型的 SparseBooleanArray 好过布尔[] 这里。
   
   
   • 初始化的 thumbnailsselection 在 ImageAdapter建筑工，然后在checkbox.setOnCheckedChangeListener修改其值（新的 OnCheckedChangeListener （）{}）。
   
   

   //初始化

    的for（int i = 0; I＆LT; ITEMCOUNT;我++）
       thumbnailsselection.put（I，FALSE）;
    

   //修改

     holder.checkbox.setOnCheckedChangeListener（新OnCheckedChangeListener（）{
       @覆盖
       公共无效onCheckedChanged（CompoundButton buttonView，布尔器isChecked）{
           INT位置= buttonView.getId（）;
           thumbnailsselection.put（位置，器isChecked）;
       }
   }）;
    




2. 删除从后到前项的 一个接一个，因为删除只影响后面的删除了一个项目的索引。

    的for（int i = ITEMCOUNT  -  1; I＆GT; = 0;我 - ）{
       位置= thumbnailsselection.keyAt（ⅰ）;
       =器isChecked thumbnailsselection.get（位置，FALSE）;    如果（！器isChecked）
           继续;    如果（位置＆LT; items.size（））
           items.remove（位置）;
   }
    




3. 显示新的数据。

     imageAdapter.notifyDataSetChanged（）;
    

am displaying names in list view, with check boxes,here i have button if i click that button that time i need to remove selected items and from list view, remain items only i need to show in list view,using below i code i can find what are the items i selected but i dont know how to remove those, can you any one suggest me

MainActivity.class: 
   public class MainActivity extends Activity {

 private ListView listview;  
 ArrayList<String> items = new ArrayList<String>();  
 private int count;  
 private boolean[] thumbnailsselection;  
 @Override  
 protected void onCreate(Bundle savedInstanceState) {  
      super.onCreate(savedInstanceState);  
      setContentView(R.layout.activity_main);  
      fillarray();  
      count = items.size();  
      thumbnailsselection = new boolean[count];  
      listview = (ListView) findViewById(R.id.listView1);  
      listview.setAdapter(new ImageAdapter(MainActivity.this));  
 }  
 private void fillarray() {  
      // TODO Auto-generated method stub  
      items.clear();  
      items.add("Android alpha");  
      items.add("Android beta");  
      items.add("1.5 Cupcake (API level 3)");  
      items.add("1.6 Donut (API level 4)");  
      items.add("2.0 Eclair (API level 5)");  
      items.add("2.0.1 Eclair (API level 6)");  

 }  
 @Override  
 public boolean onCreateOptionsMenu(Menu menu) {  
      // Inflate the menu; this adds items to the action bar if it is present.  
      getMenuInflater().inflate(R.menu.activity_main, menu);  
      return true;  
 }  
 public class ImageAdapter extends BaseAdapter {  
      private LayoutInflater mInflater;  
      private Context mContext;  
      public ImageAdapter(Context context) {  
           mContext = context;  
      }  
      public int getCount() {  
           return count;  
      }  
      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) {  
                holder = new ViewHolder();  
                convertView = LayoutInflater.from(mContext).inflate(  
                          R.layout.row_photo, null);  
                holder.textview = (TextView) convertView  
                          .findViewById(R.id.thumbImage);  
                holder.checkbox = (CheckBox) convertView  
                          .findViewById(R.id.itemCheckBox);  
                convertView.setTag(holder);  
           } else {  
                holder = (ViewHolder) convertView.getTag();  
           }  
           holder.checkbox.setId(position);  
           holder.textview.setId(position);  
           holder.checkbox.setOnClickListener(new OnClickListener() {  
                public void onClick(View v) {  
                     // TODO Auto-generated method stub  
                     CheckBox cb = (CheckBox) v;  
                     int id = cb.getId();  
                     if (thumbnailsselection[id]) {  
                          cb.setChecked(false);  
                          thumbnailsselection[id] = false;  
                     } else {  
                          cb.setChecked(true);  
                          thumbnailsselection[id] = true;  
                     }  
                }  
           });  
           holder.textview.setOnClickListener(new OnClickListener() {  
                public void onClick(View v) {  
                     // TODO Auto-generated method stub  
                     int id = v.getId();  
                }  
           });  
           holder.textview.setText(items.get(position));  
           holder.checkbox.setChecked(thumbnailsselection[position]);  
           holder.id = position;  
           return convertView;  
      }  

    public void removeItems()
      {
          notifyDataSetChanged();
      }
 }  
 class ViewHolder {  
      TextView textview;  
      CheckBox checkbox;  
      int id;  
 }  
 public void click(View v) {  
      if (v.getId() == R.id.button1) {  

           boolean noSelect = false;  

           for (int i = 0; i < thumbnailsselection.length; i++) {  
              if (thumbnailsselection[i] == true) {  
                   noSelect = true;  

                       items.remove(i);

                }  


         }  
          thumbnailsselection = new boolean[items.size()];
         adapter.removeItems(); 
      }  
 }  
}

1. Record the state of all CheckBox.

   • Data type SparseBooleanArray is better than boolean[] here.
   • Initialize thumbnailsselection in ImageAdapter constructer, and modify its values in checkbox.setOnCheckedChangeListener(new OnCheckedChangeListener() {}).

   // Initialize

   for (int i = 0; i < itemCount; i++)
       thumbnailsselection.put(i, false);
   

   // Modify

   holder.checkbox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
       @Override
       public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
           int position = buttonView.getId();
           thumbnailsselection.put(position, isChecked);
       }
   });
   

2. Remove items from back to front, one by one, because the deletion only affects indices of items behind the removed one.

   for (int i = itemCount - 1; i >= 0; i--) {
       position = thumbnailsselection.keyAt(i);
       isChecked = thumbnailsselection.get(position, false);
   
       if (!isChecked)
           continue;
   
       if (position < items.size())
           items.remove(position);
   }
   

3. Show new data.

   imageAdapter.notifyDataSetChanged();
