Actually it gives suggestion when you type.
To remove suggestion box add this property to EditText in xml layout
android:inputType="text|textNoSuggestions"
To remove mic icon from box add below property to EditText in xml layout
android:privateImeOptions="nm" // "nm" : No Mic

Display smiley button at right bottom on Android keyboard

I need to show smileys button by default when user input in my EditText.
Now keyboard for my EditText looks like:
Look at the right bottom, you will see done button.
In same time in sms app keyboard looks like:
[
At the right bottom displays smiles button.
How do I display smile button in keyboard for my EditText?
Now I have next ExitText layout:
<EditText
... // some layout params
android:inputType="textCapSentences|textAutoCorrect|textAutoComplete"/>

You can try by adding following attributes in your EditText. Missing property in you code is textShortMessage. So you can try by adding same.
android:inputType="textShortMessage|textAutoCorrect|textCapSentences|textMultiLine"
android:imeOptions="actionSend|flagNoEnterAction"

You just have to add imeOption textShortMessage.
<EditText
... // some layout params
android:inputType="textShortMessage|textCapSentences|textAutoCorrect|textAutoComplete"/>

Can I change default android keyboard Text

How to change label of any key on Android default keyboard.
I want to do something like this,

you can acheive this by using Use KeyboardView:
KeyboardView kbd = new KeyboardView(context);
kbd.setKeyboard(new Keyboard(this, R.xml.customlayout));
kbd.setOnKeyboardActionListener(new OnKeyboardActionListener() {
....
}
now you have kd which is a normal view.
The nice thing about this is that R.xml.custom refers to /res/xml/custom.xml, which defines in xml the layout of the keyboard. For more information on this file, look here: Keyboard, Keyboard.Row, Keyboard.Key.

You can use your own keyboard to change the text and style of keyboard.
Custom Keyboard

you should have a look at ImeActionLabel or ImeActionId
<EditText android:id="#+id/some_edittext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:imeOptions="actionSend">
</EditText>

Enable email keyboard on android for input type email

I am creating application with WebView. I use the WebView to show HTML pages, containing input fields. If the HTML input fields expect an email address to be typed by the user, then I want to enable an email-friendly keyboard layout. Is it possible to set up the HTML or the WebView to show an email-friendly keyboard on Android, like you can on iPhone?

You will only put
android:inputType="textEmailAddress"
in your edittext box.

yes it is posible
in your Edittext xml just add the attribute
android:inputType="textEmailAddress"
see this for more
EditText, inputType values (xml)

just add this for your EditText or TextInputEditTex or whatever editable field.
this.inputType = (InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS )
Note:
if when you try to specify the input type and doesn't work put inside one "onFocusListener", i had the same problem.

You can use the HTML5 input type email, which on recent Android versions brings up a qwerty keyboard with additional # and . keys.
<input type="email" name="myinput" />
This doesn't seem to work on Gingerbread.

Focus on the first edtitext in android

I have four edittexts the problem is when i start activity the focus will be on the last edittext , how can i make the focus on the first edittext using xml ?
Thanks

onCreate(); of Activity
EditText firsteditText=(EditText)findViewById(R.id.first);
EditText secondeditText=(EditText)findViewById(R.id.second);
EditText thirdeditText=(EditText)findViewById(R.id.third);
EditText fourtheditText=(EditText)findViewById(R.id.fourth);
firsteditText.requestFocus();

You can use the requestFocus element.

You can also add a <requestFocus/> tab in the activity xml.

In Android Studio 2.3.3, you can click on the focusedByDefault attribute in the Properties panel on the EditText you want the focus on first.
