做一個(gè)詞典，要將測試的結(jié)果在最后顯示出來。

舉例：

單詞：anderstand

選項(xiàng)：A：知道

? ? ? ? ?B：牛

? ? ? ? ?C：大便

? ? ? ? ?D：熱火隊(duì)

顯然答案是 A。

做測測試的時(shí)候，類似這樣的單詞測試有50個(gè)，每次都會讓你選擇一個(gè)的。比如我選擇了

B：牛，那么這是錯(cuò)的。

我要在最后的單詞測試中將顯示：

單詞：anderstand

選項(xiàng)： A：知道

? ? ? ? ?B：牛

? ? ? ? ?C：大便

? ? ? ? ?D：熱火隊(duì)

將正確的答案的顏色設(shè)置成為藍(lán)色，選錯(cuò)的答案設(shè)置成為紅色，類似于

-----------------------------------------------------------------------------------------------》》》

也就是動(dòng)態(tài)的顯示我們a b ?c ?d四個(gè)選項(xiàng)的顏色嘍。

listview用的是適配器是繼承了baseadapter，所以我們從網(wǎng)上找答案，

（其實(shí)，我相信，好多同學(xué)朋友，起初使用listview都是通過百度，或者是谷歌來找代碼做demo的）

于是百度，谷歌下，

代碼：

    public class MyAdapter extends BaseAdapter{
 
        private LayoutInflater mInflater;
         
         
        public MyAdapter(Context context){
            this.mInflater = LayoutInflater.from(context);
        }
        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return mData.size();
        }
 
        @Override
        public Object getItem(int arg0) {
            // TODO Auto-generated method stub
            return null;
        }
 
        @Override
        public long getItemId(int arg0) {
            // TODO Auto-generated method stub
            return 0;
        }
 
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
             
            ViewHolder holder = null;
            if (convertView == null) {
                 
                holder=new ViewHolder();  
                 
                convertView = mInflater.inflate(R.layout.vlist2, null);
                holder.img = (ImageView)convertView.findViewById(R.id.img);
                holder.title = (TextView)convertView.findViewById(R.id.title);
                holder.info = (TextView)convertView.findViewById(R.id.info);
                holder.viewBtn = (Button)convertView.findViewById(R.id.view_btn);
                convertView.setTag(holder);
                 
            }else {
                 
                holder = (ViewHolder)convertView.getTag();
            }
             
             
            holder.img.setBackgroundResource((Integer)mData.get(position).get("img"));
            holder.title.setText((String)mData.get(position).get("title"));
            holder.info.setText((String)mData.get(position).get("info"));
             
            holder.viewBtn.setOnClickListener(new View.OnClickListener() {
                 
                @Override
                public void onClick(View v) {
                    showInfo();                 
                }
            });
             
             
            return convertView;
        }
         
    }

還有： http://xqjay19910131-yahoo-cn.iteye.com/blog/1167956

代碼：

    public class MyAdapter extends BaseAdapter{  
          
        private LayoutInflater flater;  
          
        public MyAdapter(Context context) {  
            super();  
            this.flater = LayoutInflater.from(context);  
        }  
  
        public int getCount() {  
            // TODO Auto-generated method stub  
            return list.size();  
        }  
  
        public Object getItem(int arg0) {  
            // TODO Auto-generated method stub  
            return null;  
        }  
  
        public long getItemId(int arg0) {  
            // TODO Auto-generated method stub  
            return 0;  
        }  
  
        public View getView(int position, View convertView, ViewGroup parent) {  
            // TODO Auto-generated method stub  
            ViewHolder holder = null;  
            if(convertView == null){  
                holder = new ViewHolder();  
                convertView = flater.inflate(R.layout.user2, null);  
                holder.headimg = (ImageView) convertView.findViewById(R.id.headimg);  
                holder.nickname = (TextView) convertView.findViewById(R.id.nickname);  
                holder.textsign = (TextView) convertView.findViewById(R.id.textsign);  
                holder.listbtn = (Button) convertView.findViewById(R.id.listbtn);  
                convertView.setTag(holder);  
            }  
            else{  
                holder = (ViewHolder) convertView.getTag();  
            }  
            holder.headimg.setBackgroundResource((Integer)list.get(position).get("headimg"));  
            holder.nickname.setText((String)list.get(position).get("nickname"));  
            holder.textsign.setText((String)list.get(position).get("textsign"));  
            holder.listbtn.setOnClickListener(new View.OnClickListener() {  
                public void onClick(View arg0) {  
                }  
            });  
            return convertView;  
        }  
    }  
}

又或者兩者的代碼是一樣的。

于是，我弄他們的代碼下來到我的代碼中就成了這樣的：

     // 查詢歷史上搜索過的單詞 ，查詢的表是history_word
	private class TestWordResutListAdapter extends BaseAdapter {
		// List<Map<String , String>> lst ;
		private LayoutInflater mInflater;
		public TestWordResutListAdapter(Context context, List<Map<String, String>> lst) {
			// this.lst = lst ;
			this.mInflater = LayoutInflater.from(context);
			
		}

		@Override
		public int getCount() {
			// TODO Auto-generated method stub
			return lst.size();
		}

		@Override
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return position;
		}

		@Override
		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return position;
		}

		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			// 獲取ListView 每個(gè)布局文件
			
			if (convertView == null) {
				convertView = getLayoutInflater().inflate(R.layout.wordtestresult_list_item, null); // 獲取每個(gè)ListView行的布局

? 這里的

    			
			tv_wordtestresult_item_meana 
			tv_wordtestresult_item_meanb

			tv_wordtestresult_item_meand

item的四個(gè)控件是的眼神是根據(jù)item中，從數(shù)據(jù)庫來的值進(jìn)行設(shè)置的

    		String ans_index = wordListMap.get("ans_index").trim();
			String ans_press = wordListMap.get("ans_press").trim();
			
			System.out.println("------->>ans_index" + ans_index + "------>>id=" + id);
			System.out.println("------->>ans_press" + ans_press );
			
			tv_wordtestresult_item_meanb.setTag(id) ;
			
			if (ans_index.equals("1")) {  //為正確答案標(biāo)記綠色的顏色
				tv_wordtestresult_item_meana.setTextColor(Color.GREEN) ;

			else if (ans_index.equals("3")) {
				tv_wordtestresult_item_meanc.setTextColor(Color.GREEN) ;
				System.out.println("ans_index-------3>>id =" + id);
			
            }
			else if (ans_index.equals("4")) {
				tv_wordtestresult_item_meand.setTextColor(Color.GREEN) ;
				System.out.println("ans_index-------4>>id =" + id);
			
            }
			
			
			
			if (!ans_index.equals(ans_press)) { //為選擇錯(cuò)誤的標(biāo)記顏色為紅色
				System.out.println("ans_press------->>id =" + id);
				if (ans_press.equals("1")) {
					System.out.println("ans_press-------1>>id =" + id);
					tv_wordtestresult_item_meana.setTextColor(Color.RED) ;
				}
				
				else if (ans_press.equals("2")) {
					System.out.println("ans_press-------2>>id =" + id);
					tv_wordtestresult_item_meanb.setTextColor(Color.RED) ;
				}
				else if (ans_press.equals("3")) {
					System.out.println("ans_press-------3>>id =" + id);
					tv_wordtestresult_item_meanc.setTextColor(Color.RED) ;
                }

					tv_wordtestresult_item_meand.setTextColor(Color.RED) ;
                }
			}

于是，做好以后，運(yùn)行程序，當(dāng)下拉上拉listview的時(shí)候，item的顏色是不對的，就是說，不該有顏色的控件，也添加了顏色。

可能是listview這樣的情況大家遇到的比較少，我網(wǎng)上查了下，沒有這樣的例子?？啾屏耍詈蟮木尤皇沁@樣的：

如上上面的一行代碼就解決了問題了。
