android button above keyboard [duplicate]

Answer 1

Use the layout below.

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">


<EditText
    android:id="@+id/et"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

<Button
    android:id="@+id/search_image"
    android:layout_width="100dp"
    android:text="Hit"
    android:layout_centerHorizontal="true"
    android:layout_height="50dp"
    android:layout_alignParentBottom="true"
    android:layout_marginBottom="20dp"

    />
</RelativeLayout>

And manifest entry of your activity should be.

 <activity
        android:name=".MainActivity"
        android:theme="@style/AppTheme.NoActionBar"
        android:windowSoftInputMode="adjustResize">
    </activity>
