I\'m try

Answer 1

The Android support library can be imported within gradle in the dependencies :

    compile 'com.android.support:design:22.2.0'

It should be included within GradlePlease! And as an example to use it:

 <android.support.design.widget.TextInputLayout
    android:id="@+id/to_text_input_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <AutoCompleteTextView
        android:id="@+id/autoCompleteTextViewTo"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="To"
        android:layout_marginTop="45dp"
        />
</android.support.design.widget.TextInputLayout>

Btw, the editor may not understand that AutoCompleteTextView is allowed within TextInputLayout.

Answer 2

Use the TextInputLayout provided by the Material Components Library:

    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Label">

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </com.google.android.material.textfield.TextInputLayout>

You need to add the following to your module build.gradle file:

implementation 'com.google.android.material:material:1.0.0'

And use com.google.android.material.textfield.TextInputLayout in your XML:

       <com.google.android.material.textfield.TextInputLayout
            android:id="@+id/text_input_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/my_hint">

        <EditText
            android:id="@+id/editText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="UserName"/>
   </com.google.android.material.textfield.TextInputLayout>

Answer 4

Import the Support Libraries, In your project's build.gradle file, add the following lines in the project's dependencies:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile 'com.android.support:design:22.2.0'
    compile 'com.android.support:appcompat-v7:22.2.0'
}

Use following TextInputLayout in your UI Layout:

<android.support.design.widget.TextInputLayout
    android:id="@+id/usernameWrapper"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <EditText
        android:id="@+id/username"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress"
        android:hint="Username"/>

</android.support.design.widget.TextInputLayout>

Than, call setHint on TextInputLayout just after setContentView call because, to animate the floating label, you just need to set a hint, using the setHint method.

final TextInputLayout usernameWrapper = (TextInputLayout) findViewById(R.id.usernameWrapper);
usernameWrapper.setHint("Username");
