Build your own Toast

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, 400 phone, http://www.my400800.cn ");
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 ();
