带有首字母缩写词的 AutoCompleteTextview

Question

我是越南人，我使用我的语言为我的应用程序使用 Autocomplete TextView。我想制作 AutoComplete TextView，当我输入 AutoComplete TextView：“ban”时，它知道我想找到：“bạn”或“bán”或“bàn”。这意味着：我的语言中的“a”字符可以理解：á、ạ 或 à。我该怎么做。

public class Google extends Activity {

    AutoCompleteTextView edSearch;
    RelativeLayout.LayoutParams layoutParams;

    RelativeLayout rl;
    RelativeLayout rl1;

Answer 1

您可以通过编写实现android.widget.Filterable 接口的自定义适配器来实现此目的。 您的自定义过滤器可以处理越南语中不同类型的 a。

public class MyAdapter extends ArrayAdapter<String> {

   private Filter myFilter;

   public Filter getFilter() {
       if (myFilter == null) {
            myFilter= new MyArrayFilter();
       }
       return myFilter;
   }

   private class MyArrayFilter extends ArrayFilter {
       @Override
       protected FilterResults performFiltering(CharSequence prefix) {
          // Perform your filtering here. For example replace all possible a-versions with the basic a
          // Note that it's run in a background thread, so no UI interaction from here
      }

      @Override
      protected void publishResults(CharSequence constraint, FilterResults results) {
         // Gets called on the UI thread when filtering is done
         // Second param is return value from performFilter call
         // Put your results to the interface here
      }
   }
}
