I would like to add a Google +1 button to my Android NDK opengl-based app.
The docs say I should add the PlusOne view to my layout:
<com.google.android.gms.plus.PlusOneButton
xmlns:plus="http://schemas.android.com/apk/lib/com.google.android.gms.plus"
android:id="#+id/plus_one_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
plus:size="standard"
plus:annotation="inline" />
But I only have one full screen GLSurfaceView. What is the recommended way to integrate this +1 feature? Is there a lower-level way to do this?

When I saw the TabBar and the Flyout menu in .NET Maui I started wondering if its possible to create your own global object for your application.
does anyone know how to do this?
(I want to add a status icon at the corner of my screen without having to manually add it to all pages.)
You can create a simple Floating Button and add it to your pages.
You can create an image with a transparent background in your favorite editor and then assign it a location on the Page.
You can refer to the following code:
<AbsoluteLayout>
<!--Other components-->
<ImageButton Source="icon.png"
BackgroundColor="Green"
CornerRadius="80"
AbsoluteLayout.LayoutFlags="PositionProportional"
AbsoluteLayout.LayoutBounds=".95,.95,80,80" />
</AbsoluteLayout>
I want to implement this type of sliding selection list in my kotlin based android studio app. but, I don't know what actually it is. so, plz help me

An app uses ExpandableListActivity, and the usage of ExpandableListView is standard based on the document:
<ExpandableListView
android:id="#id/android:list"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:divider="#android:color/transparent"
android:dividerHeight="5dip"
android:layout_marginTop="10dip">
</ExpandableListView>
Android Studio 3.2 has the following warning:
How can I get rid of the warning?
This is probably a typo. Change it to:
"#android:id/empty"
and
"#android:id/list"
See also https://developer.android.com/reference/android/app/ListActivity
ListActivity has a default layout that consists of a single,
full-screen list in the center of the screen. However, if you desire,
you can customize the screen layout by setting your own view layout
with setContentView() in onCreate(). To do this, your own view MUST
contain a ListView object with the id "#android:id/list" (or R.id.list
if it's in code)
I don't know what is ( id="#id/android:list")
give it an normal id ( #+id/androidlist )
and handle it in your code
but if you learn how to work with ExpandableListView
I prefer this link tutorial for you ExpandableListView Link
GL sir
I have an issue which displays:
Error:(19, 29) No resource found that matches the given name
(at 'background' with value '#drawable/unpressed').
Error:Execution failed for task ':app:processDebugResources'.
com.android.ide.common.process.ProcessException:
org.gradle.process.internal.ExecException: Process 'command
'Drive:\Users\...\sdk\build-tools\23.0.1\aapt.exe'' finished with non-zero exit value 1
Basically I want to add background to an ImageButton which will change after OnTouch() Event. For that first of all, I have to add an Image (a simple scenario without an Event)
I am facing the above mentioned problem in a simple case. I don't know what mistake am I making. My code for ImageButton is:
<ImageButton
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/imageButton"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="202dp"
android:background="#drawable/unpressed"
/>
I have tried all of the solutions searched including:
Clean Solution
Rebuild Solution
Update SDK (mentioned in STACK Solution) Libraries
File > Invalidate Caches/Restart
After pasting image in drawable, synchronized it.
As iGoda informed in the Comments. How can I find where the R settings exactly are changed?
After a long time, the problem solved by:
deleting the files in the path:
C:\Users\UserName\AppData\Local\Temp
If any of the folder in above path is not visible to you, kindly show the hidden files by going into the following Options in the menu bar of Windows Explorer: Organize -> Folder and Search Options(For Windows-7)
Restart system and then check. It will all be fine.
Per the question here,
What's "tools:context" in Android layout files?
The 'tools' namespace reference (xmlns:tools="http://schemas.android.com/tools") has begun to appear in my layouts recently, and I want to know more. The original post only described the 'tools:context' attribute, but I have also noticed usage of the "tools:listitem" attribute appearing when I have designated a preview layout item for a listview, i.e.
<ListView
android:id="#+id/lvCustomer"
tools:listitem="#layout/customer_list_item" >
</ListView>
Are there more elements?
What brought me to this 'tools' namespace is that I want to be able to have 'preview-only' text (i.e. in a TextView or EditText) when using the layout designer in eclipse.
Currently, I assign the 'text' or 'hint' property for previewing text when arranging my layouts... but then I always have to remember to clear the preview value from within the code.
Ideally, instead of
<string name="preview_customer_name">Billy Bob's Roadhouse Pub</string>
...
<TextView
android:id="#+id/tvCustomerName"
android:text="#string/preview_customer_name"
</TextView>
have a something like:
<TextView
android:id="#+id/tvCustomerName"
tools:previewText="#string/preview_customer_name"
</TextView>
Thanks-
We've just added support for designtime attributes like this in Android Studio 0.2.11. See http://tools.android.com/tips/layout-designtime-attributes for more.
Think of them as design time helpers only.They do not get processed in actual view rendering at run time.
For example you want to set background of some view in your layout design when working on android studio so that you can make clear distinction where that particular view is.So you would normally do that with
android:background="#color/<some-color>"
Now risk is that sometimes we forget to remove that color and it gets shipped in apk.
instead you can do as follows:
tools:background="#color/<some-color>"
These changes will be local to android studio and will never get transferred to apk.
And also check out http://tools.android.com/tech-docs/tools-attributes for more options.
You will find tool attribute when you set object in graphical layout.
Listview (in graphical mode) -> right Click -> Preview List Content -> Choose Layout...
produces:
tools:listitem="#layout/customer_list_item"
See in layout XML below. There are 2 namespace in use "xmlns:android" and "xmlns:tools".
Tools namespace is used when the developer wants to define placeholder content that is only used in preview or in design time. Tools namespace is removed when we compiled the app.
So in the code below, I want to show the placeholder image (image_empty) that will only be visible at design time, and image1 will the actual image that will be shown when the application launch
