在android中创建一个搜索框

Question

我需要在 android 中创建一个search box，它会检查来自arraylist 的数据，如果它在那里，它将返回到该页面。

代码：

 String[] text = { "One", "Two", "Three", "Four", "Five", "Six", "Seven",
   "Eight", "Nine", "Ten" };

edittext.addTextChangedListener(new TextWatcher()
  {

   public void afterTextChanged(Editable s)
   {

   }

   public void beforeTextChanged(CharSequence s, int start,
    int count, int after)
   {

   }

   public void onTextChanged(CharSequence s, int start,
    int before, int count)
   {

    textlength = edittext.getText().length();
    text_sort.clear();
    image_sort.clear();

    for (int i = 0; i < text.length; i++)
    {
     if (textlength <= text[i].length())
     {
      if (edittext.getText().toString().
   equalsIgnoreCase((String) text[i].subSequence(0, textlength)))
      {

      }
     }
    }

我得到了search functionality 的上述代码但我需要当用户将search any keyword 时，它将从array list 进行检查，如果它在那里它将返回到该页面，否则它将显示no data found！

Answer 1

EditText 使用 AutoCompleteTextView

AutoCompleteTextView ：我在 ActionBar 中使用了它。你也可以在活动中使用它。它非常简单。

更多详情请查看artical 和code。

对于 Actionbar，您必须在代码中添加 android-suport-v4.jar 文件..

您应该尝试使用Usage of SearchView in an ActionBar 的android 功能

还提供了它的兼容性Collapsable SearchView

以下是您可以从ArrayList 尝试实现搜索的方式：

  public class SearchActivity extends ListActivity
   {
     private ArrayAdapter<String> m_arrayAdapter;
     private SearchView m_searchView;
@Override
protected void onCreate(Bundle p_savedInstanceState)
{
    super.onCreate(p_savedInstanceState);
    // setContentView(R.layout.search);
    m_arrayAdapter =
            new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, m_items);
    setListAdapter(m_arrayAdapter);
}
public boolean onCreateOptionsMenu(android.view.Menu menu)
{
    // MenuInflater inflater = getMenuInflater();
    // inflater.inflate(R.menu.activity_main, menu);
    getMenuInflater().inflate(R.menu.activity_main, menu);
    m_searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
    m_searchView.setSubmitButtonEnabled(true);//Set the submit button on search view.
    // Associate searchable configuration with the SearchView
    // SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    // SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
    // searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    m_searchView.setOnQueryTextListener(new OnQueryTextListener()
    {
        @Override
        public boolean onQueryTextSubmit(String p_query)
        {
            m_arrayAdapter.getFilter().filter(p_query);
            return true;
        }
        @Override
        public boolean onQueryTextChange(String p_newText)
        {
            m_arrayAdapter.getFilter().filter(p_newText);
            return false;
        }
    });
    return true;
};
String[] m_items = new String[] { "China", "India", "United States", "Indonesia", "Brazil",
        "Pakistan", "Nigeria", "Bangladesh", "Russia", "Japan", "Mexico", "Philippines",
        "Vietnam", "Ethiopia", "Egypt", "Germany", "Iran", "Turkey",
        "Democratic Republic of the Congo", "Thailand", "France", "United Kingdom", "Italy",
        "South Africa", "Myanmar", "South Korea", "Colombia", "Spain", "Ukraine", "Tanzania",
        "Kenya", "Argentina", "Poland", "Algeria", "Canada" };
  }
