适配器 核心代码如下：
public class ListAdapter extends BaseAdapter { private Context context; private List<item> myList; private LayoutInflater mInflater; private int selectedPosition = - 1 ; // 选中的位置 public ListAdapter(Context context, List<item> myList, int selected) { this .context = context; this .myList = myList; this .mInflater = LayoutInflater.from( this .context); selectedPosition=selected; } public int getCount() { return myList.size(); } public Object getItem( int position) { return myList.get(position); } public long getItemId( int position) { return position; } public void setSelectedPosition( int position) { selectedPosition = position; } public View getView( final int position, View convertView, final ViewGroup parent) { ViewHolder holder = null ; if (convertView == null ) { holder = new ViewHolder(); convertView = mInflater.inflate(R.layout.block_list_item, null ); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } final View cView=convertView; final ViewHolder cHolder=holder; holder.iLayout=(LinearLayout) convertView.findViewById(R.id.ll_root); holder.name = (TextView) convertView.findViewById(R.id.tv_name); holder.img = (ImageView) convertView.findViewById(R.id.iv_right); holder.name.setText(myList.get(position).getName()); System.out.println(Item值为：+selectedPosition); System.out.println(自带的为：+position); if (selectedPosition == position) { holder.iLayout.setSelected( true ); holder.iLayout.setPressed( true ); holder.iLayout.setBackgroundColor(Color.RED); } else { holder.iLayout.setSelected( false ); holder.iLayout.setPressed( false ); holder.iLayout.setBackgroundColor(Color.TRANSPARENT); } return convertView; } class ButtonView { int layoutViewId; ButtonView( int tId) { layoutViewId = tId; } } public final class ViewHolder { public TextView name; public ImageView img; public LinearLayout iLayout; } } 参考：http://www.2cto.com/kf/201407/321095.html转载于:https://www.cnblogs.com/feng666/p/4363849.html
