Android Progress bar Component ProgressBar

First is the Main.xml file

The code is as follows:

<linearlayout xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:tools= "http// Schemas.android.com/tools "android:orientation=" vertical "android:layout_width=" fill_parent "Android:layout_heigh t= "Fill_parent" ><progressbar android:id= "@+id/myprobara" style= "? Android:attr/progressbarstyle" Android:v Isibility= "Gone" android:layout_width= "Fill_parent" android:layout_height= "Wrap_content"/><ProgressBar and Roid:id= "@+id/myprobarb" style= "Android:attr/progressbarstylehorizontal" android:visibility= "Gone" android:layou T_width= "Fill_parent" android:layout_height= "wrap_content"/><progressbar android:id= "@+id/myprobarC" style = "Android:attr/progressbarstylehorizontal" android:visibility= "Gone" android:max= "+" android:progress= "0" a Ndroid:layout_width= "Fill_parent" android:layout_height= "wrap_content"/><progressbar android:id= "@+id/ Myprobard "android:visibility=" Gone "Android:max= "android:progress=" "android:secondaryprogress=" "style=" "Android:attr/progressbarstylelarge" Androi D:layout_width= "Fill_parent" android:layout_height= "wrap_content"/><progressbar android:id= "@+id/myprobarE "Android:visibility=" Gone "android:max=" "android:progress=" "android:secondaryprogress=" "style="? Android:attr/progressbarstylesmall "android:layout_width=" fill_parent "android:layout_height=" Wrap_content "/> <button android:id= "@+id/mybut" android:text= "Show progress bar" Android:layout_width= "Wrap_content" android:layout_he  ight= "Wrap_content"/></linearlayout>

Then write the Activity.java class

The code is as follows:

Start (); }} private Handler Mymessagehandler = new Handler () {public void Handlemessage (Message msg) {switch (msg.what)    {Case MainActivity.STOP:myprobarA.setVisibility (view.gone); Myprobarb.setviSibility (View.gone);    Myprobarc.setvisibility (View.gone);    Myprobard.setvisibility (View.gone);    Myprobare.setvisibility (View.gone);    Thread.CurrentThread (). interrupt ();    Break Case MainActivity.CONTINUE:if (!
