Showing ProgressDialog in Android Activity


We moved. Please visit this link for this post.

 

 

 

In situations when need to wait some operation it is good practice to notify user that operation is in progress.
For this cases in Android present several classes which can help with this. One of them I am going to demonstrate.
I will show how to use ProgressDialog class for showing progress dialog. I will show how to create preogress dialog with title and without title.

There are several show methods.

I will take this one:

ProgressDialog.show(Context context, CharSequence title, CharSequence message);

In my case I write

ProgressDialog.show(Main.this, "In progress", "Loading");

Now my progress dialog shows on activity
with_title

Okay. It is working.

What if I want to hide title? It is also very easy, just put empty string as title parameter. Example:

ProgressDialog.show(Main.this, "", "Loading...");

It is working very good.
without_title
Need to stop it:

progressDialog.dismiss();

Full code, for testing my words:

import android.app.Activity;

import android.app.ProgressDialog;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

/**

* Class for showing how to work with progress dialog

* @author FaYna Soft Labs

*/

public class Main extends Activity {

private Button clickBtn;

private ProgressDialog progressDialog;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

clickBtn = (Button) findViewById(R.id.click);

clickBtn.setText("Click me");

clickBtn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

//start the progress dialog

progressDialog = ProgressDialog.show(Main.this, "", "Loading...");

new Thread() {

public void run() {

try{

sleep(10000);

} catch (Exception e) {

Log.e("tag", e.getMessage());

}

// dismiss the progress dialog

progressDialog.dismiss();

}

}.start();

}

});

}

}

Progress dialog is one of UI classes which helps to notify user about long operations.

Personally I very often use this class.
