Android 搜索listview时忽略空格

我正在我的应用程序中使用

编辑文本

和

列表视图

。我实现了搜索功能，并将

edittext

设置为搜索栏。我正在使用

TextWatcher

即时检测更改。但是当我在

edittext

中键入空格时，所有

listview

项都消失了。那么，我如何忽略用户在

编辑文本中键入的空格呢？：

public class MainActivity extends FragmentActivity {

ArrayAdapter<String> adapter;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data);
    final EditText searchBar = (EditText) findViewById(R.id.searchbar);
    final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout);
    final ListView navList = (ListView) findViewById(R.id.left_drawer);
    final LinearLayout linearLayout = (LinearLayout)findViewById(R.id.left_drawer_layout);
    navList.setAdapter(adapter);

    searchBar.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
            // When user changed the Text
            MainActivity.this.adapter.getFilter().filter(cs);
        }

        @Override
        public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                                      int arg3) {

        }

        @Override
        public void afterTextChanged(Editable arg0) {
        }
    });

    navList.setOnScrollListener(new AbsListView.OnScrollListener() {
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            //hide keyboard
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(navList.getWindowToken(), 0);
        }

        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
        }
    });

    navList.setEmptyView(findViewById(R.id.empty));

  }
}

public类MainActivity扩展了FragmentActivity{

阵列适配器；

创建时受保护的void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity_main）；
adapter=new ArrayAdapter（这是android.R.layout.simple\u list\u item\u 1，数据）；
最终EditText搜索栏=（EditText）findViewById（R.id.searchBar）；
最终抽屉布局抽屉=（抽屉布局）findViewById（R.id.抽屉布局）；
最终ListView导航列表=（ListView）findViewById（R.id.left_抽屉）；
最终线性布局线性布局=（线性布局）findViewById（R.id.左抽屉布局）；
设置适配器（适配器）；
addTextChangedListener（新的TextWatcher（）{
@凌驾
public void onTextChanged（字符序列cs、int arg1、int arg2、int arg3）{
//当用户更改文本时
MainActivity.this.adapter.getFilter（）.filter（cs）；
}
@凌驾
更改前的公共void（字符序列arg0、int arg1、int arg2、，
int arg3）{
}
@凌驾
public void PostTextChanged（可编辑arg0）{
}
});
setOnScrollListener（新的AbsListView.OnScrollListener（）{
公共无效onScrollStateChanged（AbsListView视图，int scrollState）{
//隐藏键盘
InputMethodManager imm=（InputMethodManager）getSystemService（Context.INPUT\u方法\u服务）；
imm.hideSoftInputFromWindow（navList.getWindowToken（），0）；
}
public void onScroll（AbsListView视图、int firstVisibleItem、int visibleItemCount、int totalItemCount）{
}
});
setEmptyView（findViewById（R.id.empty））；
}
}
只是一个未实现的逻辑，请尝试

 onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {

       convert the cs to string replace space(" ") with ""  and then MainActivity.this.adapter.getFilter().filter(cs);
