Android 无需按下 Searchview 小部件即可使用
Android Searchview widget is coming without pressed it
// SearchFragment.java
public class SearchFragment extends Fragment{
Activity titleChange;
SearchView searchView;
public SearchFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.search_fragment, container, false);
titleChange.setTitle("Search Fragment");
searchView =(SearchView) view.findViewById(R.id.searchView);
searchView.setQueryHint("Search View");
searchView.setIconified(false);
searchView.setSubmitButtonEnabled(true);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
Toast.makeText(getContext(), query, Toast.LENGTH_LONG).show();
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
// Toast.makeText(getContext(), newText, Toast.LENGTH_LONG).show();
return false;
}
});
searchView.setOnSearchClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getContext(), "opened", Toast.LENGTH_LONG).show();
}
});
searchView.setOnCloseListener(new SearchView.OnCloseListener() {
@Override
public boolean onClose() {
//your code here
Toast.makeText(getContext(), "closed", Toast.LENGTH_LONG).show();
return false;
}
});
return view;
}
// search_fragment.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="16dp"
android:orientation="vertical">
<android.support.v7.widget.SearchView
android:id="@+id/searchView"
android:layout_width="wrap_content"
android:background="#fff"
android:layout_height="wrap_content">
</android.support.v7.widget.SearchView>
</LinearLayout>
搜索视图默认触发,但我想在按下它时使用它
我还需要一个反压功能,如果当 searchview 打开时,它必须关闭,即使它是打开的。
所以你能帮我 Android 开发人员吗?
查看 SearchView documentation。
在您的 onCreateView()
方法中,您正在调用 searchView.setIconified(false)
。这 "opens" 搜索视图。将其替换为 searchView.setIconified(true)
.
关于你的第二个问题,请自己做一些研究尝试解决。然后提交第二个问题,解释您目前所做的尝试和结果。
