In Android Studio What's use of "Layout Captures" tool - android-studio

"Layout Captures" tool in Android Studio showing nothing to show , how can i use this tool ?
and what's use of that ?

"Layout Captures" shows you all layout that were captured by the "Layout Inspector." Yours is empty since you have not captured any layouts. See Layout Inspector documentation.
To see how this works, capture a layout from a running emulator or attached device using the Layout Inspector which is invoked from the menu:
Here is an example of a layout that was captured. Various aspects of the layout can be inspected from this screen and can be very useful when debugging a layout.
You can now see this layout in "Layout Captures." All captures will be displayed in this tab so you can refer to them. You can also delete old layout capture files from this screen.

Find the View and container Fargment information from Click event captures in profiler

I am profiling a new application I am working with. I can see the captured pink circle, I want to find out where the view is ,In which fragment and where the click listener is defined.
Here I can only see the activity information.
It's a big project.
If you are using the latest version of Android Studio, when hovering over the green bar near the top, there should be a tooltip showing the Activity and Fragment.
Regarding how to find out the View, have you tried Android Studio's Layout Inspector? I don't know a single-click way to locate the listener but it may be feasible once you locate the view.

Rendering Problem in Android Studio Layout Preview

I've looked at the suggested answers and none of them get the layout preview to render properly. I have tried changing the theme and lowering the API.
With "AppTheme" selected as the theme, the layout preview does not render elements properly and does not match the emulator. The error messages, .xml, emulator and layout preview are shown in the screenshot.
Please let me know what information is needed. I am new-ish to android studio.
// Edit
The solution given by Jadhu worked with my previous IDE version. However, I also wanted to see the Action Bar in the preview. I tried to use the solution listed in the Jadhu's link but it still did not show the Action Bar.
After updating the IDE, I no longer need to make any changes but the Action Bar still will not appear.
// Edit 2
Make the Action Bar appear by clicking the "Eye Symbol" drop-down on the upper-left corner of the preview and selecting Show Layout Decorations.
Go to your res/values/styles.xml and change the:
"style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar""
to
"style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar""
if it doesnt work, you may find the answer Here, please feel free to take a look.

Android Studio (3.3.1). Layout decorations are not visible

Im learning Android studio now and encounter this problem with Layout Preview. I cant see phone frame.Ok, it's not big deal, but in result I see that the toolbar was not counted in design. For better understanding look at picture Virtual Device and Layout preview comparison. For layout preview and virtual device I picked Nexus 6. Screen sizes should be exactly the same. In the picture you can see the button in the layout preview. But in the virtual device the button is almost completely out of the screen bounds.
This is a link to my app
HelloWorldApp
WORKS!!!
Click that 'eye' icon and select the 'Show layout decorations'. Done.
Try this,
Click on Preview-> Visibility Symbol which named as view options
There is one option, Show Layout Decorations , Select this options.
For reference find below image:
I hope its work for you.
You can try to select device and theme for your preview window see attached image

In the new version, you can see this feature in the 'layout validation' vertical bar on the right.

Android action bar home button not including activity title

I am using the home button of the main Activity of my IM app to allow the user to change their availability status. My app is using ActionBarSherlock, which falls back to the native implementation where supported.
However, the size of the tappable area is inconsistent between Android releases:
On Android 4.2.0 and before (including the compatibility library), only the icon is tappable:
On Android 4.2.1+, icon and activity name are tappable:
How can I make the tappable area consistently include icon and activity title on all versions of Android?
I am using ActionBarCompat (and you should probably update, if you haven't already), so this may not behave exactly the same. I wanted the full title to be clickable for using the navigation drawer. For some reason, using a custom logo instead of the text makes the whole thing automatically clickable, where only the icon could be clicked before:
final ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayUseLogoEnabled(true);
actionBar.setLogo(R.drawable.im_title);
I don't know if it's possible to trigger that change while still using text with the default icon, but the setDisplay... methods and flags may be a good place to start looking.

You can use Hierarchy Viewer tool, See the definitons and Steps of how to use this tool in developer guide as shown below,
It shows visual representation of the layout's View hierarchy (the Layout View) and a magnified inspector of the display (the Pixel Perfect View).
To get the Hierarchy Viewer started:
Connect your device or launch an
emulator. From a terminal, launch
hierarchyviewer from your SDK /tools
directory. In the window that opens,
you'll see a list of Devices. When a
device is selected, a list of
currently active Windows is displayed
on the right. The is
the window currently in the
foreground, and also the default
window loaded if you do not select
another. Select the window that you'd
like to inspect and click Load View
Hierarchy. The Layout View will be
loaded. You can then load the Pixel
Perfect View by clicking the second
icon at the bottom-left of the window.
If you've navigated to a different
window on the device, press Refresh
Windows to refresh the list of
available windows on the right.
Now with the help of this tool, it shows the content is in Frame Layout, pls refer this output given by this tool.
