In this exercise we will learn to create a Progress Dialog.
Lets create a button to trigger the progress dialog.
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="Start" />
Now to trigger the progress dialog
import android.os.Bundle;
import android.app.Activity;
import android.app.ProgressDialog;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends Activity
{
Button st;
ProgressDialog dialog;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
st=(Button)findViewById(R.id.button1);
st.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
dialog=ProgressDialog.show(MainActivity.this,"Progress Dialog","Loading...",true);
Thread t=new Thread()
{
public void run()
{
try
{
Thread.sleep(5000);
dialog.cancel();
}
catch(Exception e)
{
Toast.makeText(MainActivity.this,""+e,Toast.LENGTH_LONG).show();
}
}
};
t.start();
}
});
}
}
The program has been coded to show the progress dialog for 5 seconds.
