Simple example of ProgressBar usage in Android _android

This example describes the ProgressBar usage in Android. Share to everyone for your reference, specific as follows:

ProgressBar is often used in Android, and the following examples illustrate how to use ProgressBar.

Import android.app.Activity;
Import Android.os.Bundle;
Import Android.os.Handler;
Import Android.os.Message;
Import Android.view.View;
Import Android.view.View.OnClickListener;
Import Android.widget.Button;
Import Android.widget.ProgressBar;
 public class A03activity extends activity {private ProgressBar rectangle,circle;
 Private Button Showprogressbar;
 Private final static int stop=0x10000;
 Private final static int next=0x10001;
  private int count=0; /** called the activity is a.
    * * @Override public void onCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
    Setcontentview (R.layout.main);
    Rectangle= (ProgressBar) Findviewbyid (R.id.rectangle);
    Circle= (ProgressBar) Findviewbyid (r.id.circle);
    Showprogressbar= (Button) Findviewbyid (R.id.showprogressbar);
    Rectangle.setindeterminate (FALSE);
    Circle.setindeterminate (FALSE); Showprogressbar.setonclicklistener (New Onclicklistener () {@Override public void OnClick (ViewV) {//TODO auto-generated Method Stub rectangle.setvisibility (view.visible);
  Circle.setvisibility (view.visible);
  Rectangle.setmax (100);
  Rectangle.setprogress (0);
  Circle.setprogress (0); Thread T=new Thread (new Runnable () {@Override public void run () {//TODO auto-generated method stub for (int i
    =0;i<20;i++) {try {count= (i+1) *5;
    Thread.Sleep (1000);
     if (count==19) {message msg=new message ();
     Msg.what=stop;
     Handler.sendmessage (msg);
    Break
     } else{message Msg=new message ();
     Msg.what=next;
    Handler.sendmessage (msg);
    The catch (Interruptedexception e) {//TODO auto-generated catch block E.printstacktrace ();
  }
   }
   }   
  });
  T.start ();
  }
  });
   Private Handler handler=new Handler () {@SuppressWarnings ("static-access") public void Handlemessage (msg) {
    Switch (msg.what) {case STOP:rectangle.setVisibility (view.gone);
 Circle.setvisibility (View.gone);   Thread.CurrentThread (). interrupt ();
   Break Case Next:if (!)
    Thread.CurrentThread (). Interrupted ()) {rectangle.setprogress (count);
    Circle.setprogress (count);
   } break;
}
   }
  };

 }

The

Res/layout/main.xml looks like this:

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android= "http://schemas.android.com/apk/res/" Android "Android:layout_width=" Fill_parent "android:layout_height=" fill_parent "android:orientation=" vertical " > <textview android:layout_width= "fill_parent" android:layout_height= wrap_content "android:text=" @str Ing/hello "/> <progressbar android:id= @+id/rectangle" android:layout_width= "Fill_parent" Android:lay out_height= "Wrap_content" style= "Android:attr/progressbarstylehorizontal" mce_style= "? android:attr/ Progressbarstylehorizontal "android:visibility=" Gone "/> <progressbar android:id=" @+id/circle "an Droid:layout_width= "Wrap_content" android:layout_height= "wrap_content" style= "? android:attr/ Progressbarstylelarge "mce_style=" "Android:attr/progressbarstylelarge" android:visibility= "Gone"/> & Lt Button android:id= "@+id/showprogressbar" android:layout_width="Wrap_content" android:layout_height= "Wrap_content" android:text= "show ProgressBar"/> </LinearLayout&gt
