过滤listview项后，item没有打开对应activity

Question

我有一个列表视图，项目对应于不同的活动..搜索所需项目并单击它后，位置 0 处的项目被打开，而不是对应于该项目的 activity。 . 例如：item1 项目2 项目3 search:item3，点击搜索到的item3后 problem:it会打开item1对应的activity。

这是我的代码：

Answer 1

您在这里所做的是tar根据点击的列表元素的位置创建一个新的activity。当用户搜索特定元素位置时会发生什么，您的程序将根据原始列表视图的位置tart activity。而不是使用 if(position == x) 使用其他即使您的列表视图更改也将保持不变的东西。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starting new activity like

之前使用name进行比较

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

希望对您有所帮助。 samajal nahi tar parat wichara

检查下面的代码并为新屏幕创建一个方法，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;
            }
        }    

        }
    });

    public void moveToNextActivity(int position)
    {
        if (position == 0) {
            Intent myIntent = new Intent(view.getContext(), akalp.class);
            startActivityForResult(myIntent, 0);
        }

        if (position == 1) {

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);
 }

过滤listview项后，item没有打开对应activity

After filtering the listview items, the item does not open the corresponding activity

java

search

android

listview
