问题描述
我有一个自定义行的列表视图从adapter.when被填充我点击任一行，它打开一个新的活动，我想。一切工作正常，但当我添加了搜索过滤功能，这个名单，我在其中搜索的EditText的列表项，并得到适当的过滤器，但是当我点击的过滤器产品，它不会打开与之相关的活动。它打开了与其他listItems中的关联，但并不是说我点击one.it这么多的怪异我。我不是在粘贴完整的code这里只安装所需的code等活动。
下面是我的code其中我启用了搜索功能EDITTEXT的列表视图。
edtSearch.addTextChangedListener（新TextWatcher（）{
公共无效onTextChanged（CharSequence中，诠释开始，诠释之前，
诠释计数）{
。adapter.getFilter（）过滤器（S）;
adapter.notifyDataSetChanged（）;
}
公共无效beforeTextChanged（CharSequence中，诠释开始，诠释计数，
之后INT）{
}
公共无效afterTextChanged（编辑S）{
}
}）;
}
如果就同一任何疑问，那么请发表评论，对我来说，任何帮助将是AP preciated。

解决方案
嘿家伙，我现在已经解决了这个问题，其实我对这个话题面临太大的问题。所以要粘贴解决那些有类似的问题，或将在今后面对的问题。
code，我已经在这里使用：
@覆盖
公共无效onItemClick（适配器视图＆LT;＆GT;为arg0，查看ARG1，INT位置，
长ARG3）{
TextView的电视=（TextView中）arg1.findViewById（R.id.txt）;
。字符串str = tv.getText（）的toString（）修剪（）;
如果（str.equals（国家[0]））{
意图INT0 =新的意图（Tabtwo.this，Admincost.class）;
startActivity（INT0）;
}否则如果（str.equals（国家[1]））{
意图INT1 =新的意图（Tabtwo.this，Affinity.class）;
startActivity（INT1）;
}
}
I have a listview with custom rows being populated from an adapter.when i am clicking of any row, It opening a new Activity that i wants. Everything was working fine but when I added the search filter functionality to this list and I search the listitem in edittext and gets right filter but when i clicked on an filter Item, it doesn't open the activity associated with it. It opening other activities that are associated with other listitems but not that i am clicking one.it is so much weird to me.I am not pasting complete code here only attaching the required code.
Here is my code where i enabled the search functionality to edittext on listview.
edtSearch.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before,
int count) {
adapter.getFilter().filter(s);
adapter.notifyDataSetChanged();
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void afterTextChanged(Editable s) {
}
});
}
If any query regarding the same then please comment to me,Any help would be appreciated.

解决方案
Hey guys now I have Resolved the problem, Actually I was facing much problem on this topic. So want to paste the solution to those that have similar problem or will face in future.
Code that I have use here :
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
TextView tv = (TextView) arg1.findViewById(R.id.txt);
String str = tv.getText().toString().trim();
if (str.equals(countries[0])) {
Intent int0 = new Intent(Tabtwo.this, Admincost.class);
startActivity(int0);
}else if(str.equals(countries[1])) {
Intent int1 = new Intent(Tabtwo.this, Affinity.class);
startActivity(int1);
}
}
