Android : Scroll Screen when keyboard showing using ConstraintLayout

I am using android.support.constraint.ConstraintLayoutwith four EditText and one Button. When clicked on First Edittext, SoftInput Keyboard visible then EditText and Button Hidden.
I tried in ManiFeast.xml
android:windowSoftInputMode="adjustResize"
android:windowSoftInputMode="adjustPan"
android:windowSoftInputMode="adjustResize|stateVisible"
But did work.
Any suggestion to make screen scrollable when not using ScrollView
its my Manifest.xml Activity tag
<application
.
.
.
<activity android:name=".MainActivity"
android:windowSoftInputMode="adjustResize|stateVisible"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

There is no way to tell when the keyboard is showing. So what you want isn't possible. What you can do is stick the whole thing in a ScrollView so its always scrollable. Then it will still be scrollable when the keyboard is up.

adjustResize Property Doesn't Work Properly With WebViews in Android

I have an activity that displays an HTML form in a WebView. Here's my manifest:
<application
android:allowBackup="true"
android:label="#string/app_name" >
<activity
android:name=".SMFeedbackActivity"
android:label="#string/app_name"
android:screenOrientation="locked"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
</application>
and the Activity's layout:
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/sm_feedback_webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
When tapping on a text input element within the WebView, the expected adjustResize behavior occurs: the activity resizes to show the software keyboard, while keeping the text input focused and visible. However, if I scroll and then tap any other input element (e.g. a radio button) on the page, the WebView scrolls back to the text input I was editing before.
When I edit the same form in Chrome on the same device, this behavior does not occur. I tap the text field to edit it and can then scroll elsewhere on the page and select other inputs without the page scrolling back to the text input.
The issue appears to be with the Android WebView itself and the software keyboard. Does anyone know how to solve this problem?

Android design and output not match

I'm new in Android and want to know why my app deisgn isn't same as what i deisgn in Android studio. Here is the image link:
1.Why on the top banner will appear "INC AIO" string? Is this related to the layout?How to remove?
2.Why the login button will locating too close with the password text field, not like my design?
Hope can get help frpm here. Thanks.

This is ActionBar, u can remove it, here is answer how.
U need to show us your layout file (.xml)

In AndroidManifest.xml you need to add theme inside your activity tag... to remove action bar from top.
just add this code: android:theme="#style/Theme.AppCompat.NoActionBar"
with no action bar.
example:
<activity
android:name="com.example.MainActivity"
android:label="#string/app_name"
android:theme="#style/Theme.AppCompat.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

softInputMode in fragments

I have a NavigationDawer with some fragments which contain EditTexts. When I 'open' the fragment, the layout is fine (ie. not squashed) but when I bring the keyboard up, the layout becomes squashed.
I searched around and added this to the manifest:
<activity
android:name=".Navigation_Drawer"
android:label="#string/app_name"
android:windowSoftInputMode="adjustResize" > // This being the important part
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Because the Navigation Drawer is the only activity that contains/starts these fragments, the fragment's softInputMode should be controlled by the activity, but this code does not make any difference
Thank you

Remove the code:
android:windowSoftInputMode="adjustResize"
from manifest file.

Have you tried setting the windowSoftInputMode to adjustPan?
adjustResize will resize the activity to allow room for the keyboard, which is the behaviour you are experiencing. If you set the windowSoftInputMode to adjustPan, the activity will be be 'panned', or moved upwards to make room for the keyboard.
android:windowSoftInputMode="adjustPan"

Android - Removing app Tittle bar & colored Dialog textbox

I have two questions, so i posted both here, instead of opening two questions separated.
I wonder, how can I remove my app Tittle bar?? I don't want to be seen when I start my app on phone
Can I color my dialog box like this in example -> To make my dialog tittle bar green and dialog background grey ??
I made this photo in paint, but this is how I would like to my alert dialog looks like :)

To remove the title bar beneath the Notification Bar, you can add this single line of code to your Activity declaration in the Mainfest.xml:
android:theme="#android:style/Theme.Black.NoTitleBar"
This is how I used it:
<activity
android:name=".Splash"
android:theme="#android:style/Theme.Black.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

For Question 1:
use requestWindowFeature(Window.FEATURE_NO_TITLE);
For Question 2:
How to change dialog background color programmatically?
