Toast用于向用户显示一些帮助/提示。下面我做了5中效果，来说明Toast的强大，定义一个属于你自己的Toast。
1.默认效果

代码

Toast.makeText(getApplicationContext(), "默认Toast样式",
Toast.LENGTH_SHORT).show();

2.自定义显示位置效果

代码

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

3.带图片效果

代码

toast = Toast.makeText(getApplicationContext(),
    "带图片的Toast", 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.完全自定义效果

代码

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("完全自定义Toast");
   toast = newToast(getApplicationContext());
   toast.setGravity(Gravity.RIGHT| Gravity.TOP, 12, 40);
  toast.setDuration(Toast.LENGTH_LONG);
   toast.setView(layout);
   toast.show();
