转载别人的写的不错，自己添加点注意事项，号称有5种效果。

1.默认效果

代码

        
                
  1. Toast.makeText(getApplicationContext(),"默认Toast样式", 
    2.             
  2. Toast.LENGTH_SHORT).show(); 
    3.             
    4.             
  4.  
    5.             
    6.

2.自定义显示位置效果

代码

        
                
  1. toast=Toast.makeText(getApplicationContext(), 
    2.             
  2. "自定义位置Toast",Toast.LENGTH_LONG); 
    3.             
  3. toast.setGravity(Gravity.CENTER,0,0);

    39.             
  39. </LinearLayout>
    40.             
    41.

注意： 使用toast = new Toast(context); 一定要先 toast.setView() ，然后才能toast.Show() 不然会出错。同时，我使用

LinearLayout toastView = (LinearLayout) toast.getView(); 然后再在这个LinearLayout种添加TextView会出错，后来就直接定义一个LinearLayout了。
