Show ProgressDialog to wait load

We need to read an txt file online, in wait time, we want to show Dialog Progress.

Declare a textView and a progressdialog to above Override.

TextView t;

ProgressDialog mProgressDialog;

In xml file create a textView.

<TextView

 android:id="@+id/te"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:textSize="15sp"

 android:text="@string/hello_world" />

Copy to below setContentView.

t = (TextView) findViewById(R.id.te);

mProgressDialog = new ProgressDialog(this);

mProgressDialog.setMessage("Loading, please wait...");

mProgressDialog.show();

Create a thread.

new Thread() {

        @Override

        public void run() {

             String path = "http://www.oracle.com/technetwork/java/readme-2-149793.txt";

         

   URL u = null;

    try {

    u = new URL(path);

  HttpURLConnection c = (HttpURLConnection) u.openConnection();

   c.setRequestMethod("GET");

   c.connect();

   InputStream in = c.getInputStream();

 final ByteArrayOutputStream bo = new ByteArrayOutputStream();

   byte[] buffer = new byte[4096];

    in.read(buffer); // Read from Buffer.

   bo.write(buffer); // Write Into Buffer.

      runOnUiThread(new Runnable() {

                    @Override

                    public void run() {                                                                                           

                      String a=bo.toString();

                      t.setText(a);      

                        try {

                            bo.close();

                        } catch (IOException e) {

                            e.printStackTrace();

                        }

                    }

                });

            } catch (MalformedURLException e) {

                e.printStackTrace();

            } catch (ProtocolException e) {

                e.printStackTrace();

            } catch (IOException e) {

                e.printStackTrace();

            }

       if(mProgressDialog.isShowing())

        {

        mProgressDialog.dismiss();

        }

    }

}.start();
