Effects of Android Toast

From: http://www.cnblogs.com/salam/archive/2010/11/10/1873654.html

Toast is used to display some help/prompts to users. The following is an example of how Toast works. It defines your own Toast.

1. Default Effect

Code

Toast. makeText (getApplicationContext (), "Default Toast style ",
Toast. LENGTH_SHORT). show ();

 

2. Custom display Position Effect

Code

Toast = Toast. makeText (getApplicationContext (),
"Custom location Toast", Toast. LENGTH_LONG );
Toast. setGravity (Gravity. CENTER, 0, 0 );
Toast. show ();

 

3. image effects

 

Code

Toast = Toast. makeText (getApplicationContext (),
"Toast with image", Toast. LENGTH_LONG );
Toast. setGravity (Gravity. CENTER, 0, 0 );
LinearLayout toastView = (LinearLayout) toast. getView ();
ImageView imageCodeProject = new ImageView (getApplicationContext ());
ImageCodeProject. setImageResource (R. drawable. icon );
ToastView. addView (imageCodeProject, 0 );
Toast. show ();

 

4. Fully customized results

Code

LayoutInflater inflater = getLayoutInflater ();
View layout = inflater. inflate (R. layout. custom,
(ViewGroup) findViewById (R. id. llToast ));
ImageView image = (ImageView) layout
. FindViewById (R. id. tvImageToast );
Image. setImageResource (R. drawable. icon );
TextView title = (TextView) layout. findViewById (R. id. tvTitleToast );
Title. setText ("Attention ");
TextView text = (TextView) layout. findViewById (R. id. tvTextToast );
Text. setText ("Fully customized Toast ");
Toast = new Toast (getApplicationContext ());
Toast. setGravity (Gravity. RIGHT | Gravity. TOP, 12, 40 );
Toast. setDuration (Toast. LENGTH_LONG );
Toast. setView (layout );
Toast. show ();

 

5. other threads

Code

New Thread (new Runnable (){
Public void run (){
ShowToast ();
}
}). Start ();
