Android : Rotate Vector Image to 90 degree

For me the best works when using pivot of the center of the view. Please notice that I've used as center half of viewport - not width/height

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="36dp"
    android:height="36dp"
    android:viewportWidth="24"
    android:viewportHeight="24"
    >

    <group
        android:rotation="45"
        android:pivotY="12"
        android:pivotX="12"
        >
        <path
            android:fillColor="@android:color/white"
            android:pathData="M19,13h-6v6h-2v-6H5v-2h6V5h2v6h6v2z"
            />
    </group>

</vector>

Try This Way , I have used the group tag outside of the image path data in vector drawable file.

First Type :

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"

android:viewportWidth="314.015"
android:viewportHeight="314.015">
<group
    android:translateX="314.015"
    android:rotation="90">
<path
    android:fillColor="#FCD83500"
    android:pathData="M157.007,0C70.291,0 0,70.289 0,157.007c0,86.712 70.29,157.007 157.007,157.007c86.709,0 157.007,-70.295 157.007,-157.007C314.014,70.289 243.716,0 157.007,0zM31.403,157.015c0,-69.373 56.228,-125.613 125.604,-125.613V282.62C87.631,282.62 31.403,226.38 31.403,157.015z" />

</group>
</vector>

Second Type :

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportWidth="314.015"
android:viewportHeight="314.015">
<group
    android:translateX="314"
    android:scaleX="-1"
android:rotation="0">
<path
    android:fillColor="#FCD83500"
    android:pathData="M157.007,0C70.291,0 0,70.289 0,157.007c0,86.712 70.29,157.007 157.007,157.007c86.709,0 157.007,-70.295 157.007,-157.007C314.014,70.289 243.716,0 157.007,0zM31.403,157.015c0,-69.373 56.228,-125.613 125.604,-125.613V282.62C87.631,282.62 31.403,226.38 31.403,157.015z" />
</group>
</vector>

Third type:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportWidth="314.015"
android:viewportHeight="314.015">
<group
    android:translateY="314.015"
    android:rotation="270">
<path

    android:pathData="M157.007,0C70.291,0 0,70.289 0,157.007c0,86.712 70.29,157.007 157.007,157.007c86.709,0 157.007,-70.295 157.007,-157.007C314.014,70.289 243.716,0 157.007,0zM31.403,157.015c0,-69.373 56.228,-125.613 125.604,-125.613V282.62C87.631,282.62 31.403,226.38 31.403,157.015z" />
</group>
</vector>

In fact you can not rotate vector.xml because it drawn by pathData, unless you do it in another combination.

you can separate TextView and ImageView and use it like this:

  <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginLeft="16dp"
            android:layout_marginRight="16dp"
            android:layout_weight="1"
            android:gravity="center_vertical"
            android:text="Set time"
            android:textAppearance="@style/Base.TextAppearance.AppCompat.Medium" />

        <ImageButton
            android:id="@+id/close_dialog"
            android:layout_width="?attr/actionBarSize"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/selectableItemBackgroundBorderless"
            android:rotation="45"
            android:src="@drawable/ic_close_black_24dp" />

    </LinearLayout>

For those looking for the fourth variant, to flip something upside down, the code looks like this:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
  android:width="24dp"
  android:height="24dp"
  android:viewportWidth="24.0"
  android:viewportHeight="24.0">
  <group
    android:translateY="24.0"
    android:scaleY="-1"
    android:rotation="0">
    <path
      android:fillColor="#FF000000"
      android:pathData="M1,21h4L5,9L1,9v12zM23,10c0,-1.1 -0.9,-2 -2,-2h-6.31l0.95,-4.57 0.03,-0.32c0,-0.41 -0.17,-0.79 -0.44,-1.06L14.17,1 7.59,7.59C7.22,7.95 7,8.45 7,9v10c0,1.1 0.9,2 2,2h9c0.83,0 1.54,-0.5 1.84,-1.22l3.02,-7.05c0.09,-0.23 0.14,-0.47 0.14,-0.73v-1.91l-0.01,-0.01L23,10z"/>
  </group>
</vector>
