过滤listview项后，该项不会打开相应的活动

Question

我有一个列表视图，项目对应不同的活动。在搜索所需的项目并点击它之后，位置0的项目被打开而不是与项目相对应的活动... EG：item1     ITEM2     项目3 搜索：item3，点击搜索的项目3 问题：它将打开与item1对应的活动。

这是我的代码：

检查以下代码并为新屏幕创建一种方法，如下所示，

  listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        TextView tv = (TextView) view.findViewById(R.id.textViewName);
        String strSelectedString = tv.getText().toString();
        for(int selectedPosition = 0; selectedPosition  < names.lenght; selectedPosition++)
        {
            if(names[selectedPosition].equalsIgnoreCase(strSelectedString))
            {
                moveToNextActivity(selectedPosition);
                break;
            }
        }

Answer 2

你在这里做的是根据点击的听众位置开始新的活动。当用户搜索特定位置时，会发生什么变化，并且您的程序将根据原始列表视图的位置开始活动。而不是使用if（position == x）使用其他将保持相同的内容，即使列表视图发生更改。您可以使用代码

获取元素详细信息

  Object o = lv1.getItemAtPosition(position);
  ItemDetails obj_itemDetails = (ItemDetails)o;
  String name =obj_itemDetails.getName();

然后在开始新活动之前使用名称进行比较，如

if(name.equals(sukharta)){
Intent myIntent = new Intent(view.getContext(), Sukharta.class);
startActivityForResult(myIntent, 0);
}

我希望这会有所帮助。 samajal nahi tar parat wichara

Answer 3

尝试

 Object o = lv1.getItemAtPosition(position);
 ItemDetails obj_itemDetails = (ItemDetails)o;
 String name =obj_itemDetails.getName();
 if(name.equals(sukharta)){
 Intent myIntent = new Intent(view.getContext(), Sukharta.class);
 startActivityForResult(myIntent, 0);
 }
