如何创建含底座适配器搜索 [英] How to create search with base adapter

问题描述

如何创建带有底座适配器搜索选项？以下是我已经尝试了样品code ......请提示

 公共类ListViewAdapter延伸BaseAdapter
   {//创建一个适配器，我们不得不延长BaseAdapter而不是活动，或什么的。  私人活动活动;
  私人的ArrayList＆LT;＆HashMap的LT;字符串，字符串＆GT;＆GT;数据;
  私有静态LayoutInflater吹气= NULL;
公共ListViewAdapter（活动一，ArrayList的＆LT;＆HashMap的LT;字符串，字符串＆GT; D 1和D）{
    活性=一个;
    数据= D;
    吹气=（LayoutInflater）activity.getSystemService（Context.LAYOUT_INFLATER_SERVICE）;}公众诠释的getCount（）{//获取ListView中元素的个数
    返回data.size（）;
}公共对象的getItem（INT位置）{//此方法的对象按位置返回
    返回的位置;
}众长getItemId（INT位置）{//通过位置获取项目ID
    返回的位置;
}公共查看getView（INT位置，查看convertView，父母的ViewGroup）{// getView方法是与我们的个性化行填充列表视图的方法
    查看VI = convertView;
    如果（convertView == NULL）
        VI = inflater.inflate（R.layout.layout1，NULL）; //列表视图中的每一个项目使用XMLlistview_row的设计    TextView的ID =（TextView中）vi.findViewById（R.id.textView1）; //这里是在listview_row XML文件中的两个textviews
    TextView的名字=（TextView中）vi.findViewById（R.id.textView2）; //你可以输入你想要的任何东西，按钮，单选按钮，图像等
    TextView的LOC =（TextView中）vi.findViewById（R.id.textView3）;
    TextView的DESC =（TextView中）vi.findViewById（R.id.textView4）;
    TextView的状态=（TextView中）vi.findViewById（R.id.textView5）;    HashMap的＆LT;字符串，字符串＆GT;哈希=新的HashMap＆LT;字符串，字符串＆GT;（）; //我们需要一个HashMap来存储我们的数据对任何项目
    哈希= data.get（位置）;
    id.setText（hash.get（SaActivity.KEY_ACCOUNTNUMBER））; //我们个性化我们行的项目。
    name.setText（hash.get（SaActivity.KEY_NAME））;
   loc.setText（hash.get（SaActivity.KEY_STATUS））;
   desc.setText（hash.get（SaActivity.KEY_DESC））;
    status.setText（hash.get（SaActivity.KEY_NAME））;    返回VI;
  } }
 

解决方案

你必须学习基本的东西有关适配器和搜索控制，然后尝试实现你想要什么。首先

我建议你看看这个，并尝试实现你想要的。这是仅供参考，了解你的概念。

How to create search option with base adapter? Here is the sample code which i have tried......pls suggest

public class ListViewAdapter extends BaseAdapter 
   {     //To create an adapter we have to extend BaseAdapter instead of Activity, or whatever.

  private Activity activity;
  private ArrayList<HashMap<String, String>> data;
  private static LayoutInflater inflater=null;


public ListViewAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
    activity = a;
    data=d;
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}

public int getCount() {   //get the number of elements in the listview
    return data.size();
}

public Object getItem(int position) {   //this method returns on Object by position
    return position;
}

public long getItemId(int position) {   //get item id by position
    return position;
}

public View getView(int position, View convertView, ViewGroup parent) {   //getView method is the method which populates the listview with our personalized rows
    View vi=convertView;
    if(convertView==null)
        vi = inflater.inflate(R.layout.layout1, null);       //every item in listview uses xml "listview_row"'s design 

    TextView id = (TextView)vi.findViewById(R.id.textView1);  //Here are two textviews in the listview_row xml file
    TextView name = (TextView)vi.findViewById(R.id.textView2);   // You can enter anything you want, buttons, radiobuttons, images, etc.
    TextView loc = (TextView)vi.findViewById(R.id.textView3);
    TextView desc = (TextView)vi.findViewById(R.id.textView4);
    TextView status = (TextView)vi.findViewById(R.id.textView5);

    HashMap<String, String> hash = new HashMap<String, String>();  //We need a HashMap to store our data for any item
    hash = data.get(position);


    id.setText(hash.get(SaActivity.KEY_ACCOUNTNUMBER));  //We personalize our row's items.
    name.setText(hash.get(SaActivity.KEY_NAME));
   loc.setText(hash.get(SaActivity.KEY_STATUS));
   desc.setText(hash.get(SaActivity.KEY_DESC));
    status.setText(hash.get(SaActivity.KEY_NAME));

    return vi;
  }

 }

First of all you have to learn basic thing about adapter and search control and then try to implement what you want.

I suggest you to see this and try to implement as you want. This is only for reference to learn your concept.
