This is ProgressDialog Code:

package com.etr.progressdialogdemo;

import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.os.Handler;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class ProgressDialogActivity extends Activity {
ProgressDialog progressDialog;
Handler progressHandler;
int count;
Button start;

@Override
protected void onCreate(Bundle savedInstanceState) {

try {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_progress_dialog);

progressHandler = new Handler();

start = (Button) findViewById(R.id.button1);
start.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
progress();
}
});

} catch (Exception e) {

Log.v("Exception", Log.getStackTraceString(e));

}
}

public void progress() {

progressDialog = new ProgressDialog(this);
progressDialog.setTitle("ProgressDialog ...");
progressDialog.setMessage("Download/Upload in progress ...");
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setProgress(0);
progressDialog.setMax(100);
progressDialog.show();
new Thread(new Runnable() {
@Override
public void run() {

try {

while (progressDialog.getProgress() <= progressDialog
.getMax()) {

Thread.sleep(2000);
progressHandler.post(new Runnable() {

public void run() {

progressDialog.incrementProgressBy(5);

}

});

if (progressDialog.getProgress() == progressDialog
.getMax()) {

progressDialog.dismiss();
       break;

}

}

} catch (Exception e) {

}

}

}).start();

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.progress_dialog, menu);
return true;
}

}

This is code for layout file :

<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=".ProgressDialogActivity" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="78dp"
        android:text="Start ProgressDialog" />

</RelativeLayout>
