Can anyone tell how make Search View hint in centre? Thanks in advance.
If you are using androidx. Use this code
val searchEditText = searchView.findViewById(androidx.appcompat.R.id.search_src_text) as EditText
searchEditText.gravity = Gravity.CENTER
To center the hint and query text use a costume style for your search view :
<style name="AppSearchView" parent="Widget.AppCompat.SearchView" >
<item name="android:textAlignment">center</item>
</style>
and then apply this style to your search view :
<android.support.v7.widget.SearchView
android:layout_width="match_parent"
android:layout_height="wrap_content"
...
app:theme="#style/AppSearchView" />
To center the hint on the SearchView you need to center the gravity in the EditText contained in the SearchView.
You can find that specific view by using the Layout Inspector in Android Studio (Tools->Android->Layout Inspector). When you click on the search view in your UI, you can see it has a SearchView$SearchAutoComplete. That's an inner class in the SearchView which extends AutoCompleteTextView, which extends EditText. So, that's the view you want to change. Observe in the property-value pane of the Layout Inspector that the id is id/search_src_text so you can use that to get the view and center the gravity, like this:
int id = getResources().getIdentifier("android:id/search_src_text", null, null);
EditText searchEditText = (EditText) mSearchView.findViewById(id);
if (searchEditText != null) {
searchEditText.setGravity(Gravity.CENTER);
}
Since the id of the EditText isn't officially documented, there's a null check in there just in case the id changes or isn't consistent everywhere.
For android.support.v7.widget.SearchView, use the following:
public static void centerHintText(SearchView searchView){
EditText searchEditText = (EditText) searchView.findViewById(R.id.search_src_text);
if (searchEditText != null) {
searchEditText.setGravity(Gravity.CENTER);
}
}
I followed Cody's example but I would like to add onto Cody's answer above that it might actually be better to cast the found view to SearchView.SearchAutoComplete (a public static class) instead of EditText, since that's the view directly associated with R.id.search_src_text. This is to avoid any future problems if the Android team decides to swap out the inherited EditText class for another class.

I'm working with Android TV for the first time and I'm learning to use Leanback by modifying the example tv app that is provided.
The issue I'm having is that when I press left on the first item in the lists the navigation drawer opens and focus goes to the headers in the navigation drawer. When this happens, the info_field view in the ImageCardViews collapse behind the image.
What happens: The info field on the ImageCardView hides when I open the navigation drawer.
What I want to Happen: The info field remains visible when I open the navigation drawer.
I'm sure there's a way to do this because I've seen it in some Android TV apps, like Twitch. What's the best way to have the info_field visible when the navigation drawer is open?
I've worked out how to do it. In the CardPresenter, in onCreateViewHolder, when creating the ImageCardView I've overridden the BaseCardView method, setActivated(boolean activated) to always pass 'true' into it's super. And then call setActivated so that it's activated from the beginning. Like this:
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent) {
ImageCardView cardView = new ImageCardView(parent.getContext()) {
#Override
public void setActivated(boolean activated) {
super.setActivated(true);
}
#Override
public void setSelected(boolean selected) {
updateCardBackgroundColor(this, selected);
super.setSelected(selected);
}
};
cardView.setActivated(true);
cardView.setFocusable(true);
cardView.setFocusableInTouchMode(true);
return new ViewHolder(cardView)
}
So that did the trick for me. The ImageCardView never collapses.
I think if you look at this SO post you'll get most of the way there. The info view hides due to what leanback calls "expanding".
Try just calling enableMainFragmentScaling(false); in your BrowseFragment and see if that does what you want. If it doesn't feel like exactly what you want, refer to the post I linked to.
Additionally, if you've tried what I recommend in the linked SO post, you could also call the API on the BaseCardView setInfoVisibility() and pass it CARD_REGION_VISIBLE_ALWAYS. This just requires calling on a reference to your card which shouldn't need an override of the Presenter or Card.
I want to show or hide a subview in a fragment when it is shown or hidden, but no way to check the fragment is visible to user.
In android native, it seems to have a method, but Xamarin no.
Do you have any special way to get it?
I can see only a property for fragment.
public override bool UserVisibleHint {
get {
return base.UserVisibleHint;
}
set {
base.UserVisibleHint = value;
}
}
But I need a method to check this.
thanks.
You can use the IsVisible property on the Fragment (see: https://developer.xamarin.com/api/property/Android.App.Fragment.IsVisible/)
Additionally, you can override the OnHiddenChanged method on your fragment class to get notified when the Fragment's visibility changes
it seems to have a method, but Xamarin no.
What method are you referring to?
I have a window editor that holds nodes. I would like to open a custom inspector when one of these nodes is selected. The node class is a custom serializable class. Is this possible?.
It seems that custom inspectors can be created manually through the Editor.CreateEditor method but can't see how to let it appear docked like an usual inspector in the unity inspector window.
I would like to achieve the same behaviour that we have when we select a gameobject in sceneview that inmediately show properties for the object (Components, etc...) in the unity inspector.
Cheers
As I'm not sure what you're asking, here are multiple different solutions;
Selection
If you just want your nodes to become the focus of the hierarchy, then in your custom window's OnGUI method, use the code below;
[CustomEditor(typeof(NodeManager))]
public class NodeManager : EditorWindow
{
private static NodeManager window;
private Node[] m_nodes;
[MenuItem("Custom Windows/Node Inspector")]
public static void Init()
{
if(window == null)
window = GetWindow<NodeManager>("Node Manager", true, typeof(SceneView));
}
public void OnGUI()
{
m_nodes = GameObject.FindObjectsOfType<Node>();
foreach(Node node in m_nodes)
{
GUILayout.BeginHorizontal();
{
GUILayout.Label(node.name);
if (GUILayout.Button("Select"))
Selection.objects = new Object[] { node.gameObject };
}
GUILayout.EndHorizontal();
}
}
}
This adds a Button for each object in your custom window view, that will then select that object in the hierarchy.
Auto-Docking
I originally found the second response to this question, which goes into the details of parameters of the GetWindow method, and with this you can clearly see how to dock the window (I've converted it from JS to C# below).
(I looked fairly extensively in UnityEditor and UnityEditorInternal namespaces but couldn't find the Hierarchy or the Inspector).
GetWindow<T>(string title, bool focus, params System.Type[] desiredDockNextTo)
Which we can write for this example as;
EditorWindow.GetWindow<NodeInspector>("Node Test", true, typeof(SceneView));
This example docks the windows next to the SceneView window. This functionality can be combined with a custom inspector's OnInspectorGUI method, to automatically launch the custom node window, if it's not already open.
[CustomEditor(typeof(Node))]
public class NodeInspector : Editor
{
public override void OnInspectorGUI()
{
base.OnInspectorGUI();
NodeManager.Init();
}
}
Sorry if this isn't what you are looking for, if it's not then please give more details and I will amend my answer to better suit the question.
Hope this helped.
Has a possibility, you can make a custom ScriptableObject and Custom Editor for It, and when open the node inspector, just find a instance of the scriptable object and use Selection.selectedObject = scriptableObject, and in the custom editor, make a static field called 'editor' to draw inside.
It will work.
I have a scenario where I need to set focus dynamically on search icon in browse fragment .For that I need to get reference of the search icon.Any idea how it can be done.
Thanks
BrowseFragment class accesses search icon using title view's getSearchAffordanceView()
private final BrowseFrameLayout.OnFocusSearchListener mOnFocusSearchListener =
new BrowseFrameLayout.OnFocusSearchListener() {
#Override
public View onFocusSearch(View focused, int direction) {
// If headers fragment is disabled, just return null.
if (!mCanShowHeaders) return null;
final View searchOrbView = mTitleView.getSearchAffordanceView();
.
.
.
Since mTitleView is BrowseFragment's private member, you cannot get search icon reference directly. The only properties you can control for search affordance in the fragment title are: visibility and color. Visibility is controlled by the presence of a search listener.
I want to create a custom filter for my DataTable. I would like to create a button that, when clicked on it, changes the table its data. I know about the ChoiceFilteredPropertyColumn that wicket has to offer but this is, according to my understanding of it, a dropdown filter.
I am trying to achieve something like the following picture (Pancakes is the clickable button):
Could someone point me in the right direction?
Well... the superclass of ChoiceFilteredPropertyColumn is FilteredPropertyColumn which might do the trick. Otherwise you could always implement your own Column that implements IFilteredColumn the way you like it.
Look at how the implemented `DataTable' here: http://www.packtpub.com/sites/default/files/1605OS-Chapter-5-Displaying-Data-Using-DataTable.pdf
Then you could implement your dropdown button filter like you want it and filter with the selected value the DataTable.
I solved this question by creating a custom filter (just a panel with some markup) and return it in the getFilter method of a custom FilteredPropertyColumn.
FilteredPropertyColumn:
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/extensions/markup/html/repeater/data/table/filter/FilteredPropertyColumn.html
getFilter method:
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/extensions/markup/html/repeater/data/table/filter/IFilteredColumn.html#getFilter%28java.lang.String,%20org.apache.wicket.extensions.markup.html.repeater.data.table.filter.FilterForm%29
ButtonFilter class:
public class ButtonFilter extends Panel {
...
}
In custom FilteredPropertyColumn class:
#Override
public Component getFilter(String componentId, FilterForm<?> form) {
return new ButtonFilter<Y>(componentId, getFilterModel(form), filterChoices);
}
