How to set ProgressBar at the center screen in frame layout?

I am using following code, but my progress bar is not displaying in the center of frame layout. I want to avoid padding to my progressbar.Can any one please explain? It is perfectly working if i am using "Linear Layout"

<?xml version="1.0" encoding="UTF-8"?>
<FrameLayout xmlns:android="http:开发者_StackOverflow中文版//schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center_vertical|center_horizontal">

    <ProgressBar android:id="@+id/progress_bar"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" />

    <ImageView android:id="@+id/gallery_img"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" />

 </FrameLayout>

In the layout xml for your progressBar set the android:layout_gravity (instead of android:gravity) to "center"

android:layout_gravity = "center"

---

Use

android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_centerInParent="true"

Example:

 <ProgressBar android:layout_width="wrap_content" android:layout_height="wrap_content"
     android:layout_centerHorizontal="true"
     android:layout_centerVertical="true"
     android:layout_centerInParent="true" />

android:gravity attribute is not supported on ProgressBar

FrameLayout does not have android:gravity. You need to set android:layout_gravity on the ProgressBar instead.

---

<ProgressBar
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ***android:layout_gravity="center"*** /> 

add this line in

 <ProgressBar
              android:layout_gravity="center" />

---

Just change your Layout as RelativeLayout and add android:layout_centerInParent="true" to your ProgressBar.

<ProgressBar
android:id="@+id/progBar"
android:indeterminateDrawable="@drawable/my_progress_indeterminate"
android:layout_height="50dp" 
android:layout_centerInParent="true"
android:layout_width="50dp">
</ProgressBar>

---

<ProgressBar
    android:id="@+id/progressBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_centerInParent="true"
    />

As of 2018, you need to set the below attribute:

android:layout_centerInParent="true"

---

Working solution as of 2017

android:layout_gravity="center"

---

you must set the postion in pixels as in framelayout different components overlap each other. So, you can try it by setting pixels in dip.
