How to implement progressBar while loading data?

Question

I want to implement progressBar like on the picture below.

Right now, I have AsyncTask whic is sperated from fragments classes, and I use that AsyncTask to load data, and right now I have implement progressBar dialog, but I want to get rid of that, because I want make a better UX.

I show that ProgressBar dialog in onPreExecute() method, and then dismiss it onPostExecute.

So, how I can implement background Progress bar like on the picture below

Dude,

If you really just want a progress bar like the picture you posted, you can simply set the progress bar indeterminate property to true :)

You can eighter do on code or directly on the xml.

In code:

yourProgressBar.setIndeterminate(true);

In your XML, just set the attribute indeterminate to true.

Here's is a simple layout as an example:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

<ProgressBar
    android:id="@+id/progressBar1"
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:indeterminate="true" />

</RelativeLayout>
