Buffer progress bar or load progress bar

Buffering progress bars or loading progress bars. During page or video loading, in order to better experience interaction between the UI and APP functions, these buffering loading wait effects are essential;

Let's take a look at the animation effect of rotation: So their specific source code is here: loading_1:

<?xml version="1.0" encoding="utf-8"?><rotate     xmlns:android="http://schemas.android.com/apk/res/android"    android:fromDegrees="0"    android:pivotX="50%"    android:pivotY="50%"    android:toDegrees="1080.0" >    <shape        android:innerRadiusRatio="3"        android:shape="ring"        android:thicknessRatio="8"        android:useLevel="false" >        <gradient            android:centerColor="#FFDC35"            android:centerY="0.50"            android:endColor="#CE0000"            android:startColor="#FFFFFF"            android:type="sweep"            android:useLevel="false" />    </shape></rotate>

Loading_2:

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android" >    <item >        <rotate            android:drawable="@drawable/movie_loading"            android:fromDegrees="0.0"            android:pivotX="50.0%"            android:pivotY="50.0%"            android:toDegrees="1080.0" />    </item></layer-list>

Loading_3:

<?xml version="1.0" encoding="UTF-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android"    android:oneshot="false" >    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_01"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_02"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_03"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_04"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_05"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_06"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_07"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_08"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_09"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_10"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_11"            android:gravity="left" />    </item>    <item android:duration="150">        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/loading_12"            android:gravity="left" />    </item></animation-list>

Activity_main.java:

<LinearLayout 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:orientation="horizontal"    android:gravity="center_horizontal"    android:background="#222222">    <ProgressBar        android:id="@+id/loading_1"        android:layout_width="50dp"        android:layout_height="50dp"        android:layout_marginTop="60dp"        android:indeterminate="false"        android:padding="5dp"        android:indeterminateDrawable="@drawable/loading_1" />    <ProgressBar        android:id="@+id/loading_2"        android:layout_width="50dp"        android:layout_height="50dp"        android:layout_marginTop="60dp"        android:indeterminate="false"        android:padding="5dp"        android:indeterminateDrawable="@drawable/loading_2" />    <ProgressBar        android:id="@+id/loading_3"        android:layout_width="50dp"        android:layout_height="50dp"        android:indeterminate="false"        android:layout_marginTop="60dp"        android:padding="5dp"        android:indeterminateDrawable="@drawable/loading_3" /></LinearLayout>

You do not need to add any code in activity. java!
