Android Toast Encyclopedia (five scenarios) build your own toast

Toast is used to display some help/hints to the user. Below I've done 5 effects to illustrate the power of toast and define a toast that belongs to you.

1. Default effect

Code

Toast.maketext (Getapplicationcontext (), default toast style,
Toast.length_short). Show ();

2. Customize the display position effect

Code

Toast = Toast.maketext (Getapplicationcontext (),
"Custom Location Toast", Toast.length_long);
Toast.setgravity (gravity.center, 0, 0);
Toast.show ();

3. With picture effect

Code

Toast = Toast.maketext (Getapplicationcontext (),
"Toast with pictures", 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 customizable effects

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 customizable 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 ();
