Toast是Android中用來顯示顯示信息的一種機制，和Dialog不一樣的是，Toast是沒有焦點的，而且Toast顯示的時間有限，過一定的時間就會自動消失。

1.默認效果:

代碼:
Toast.makeText(getApplicationContext(), "默認Toast樣式",
     Toast.LENGTH_SHORT).show();

2.自定義顯示位置效果:

代碼:
toast = Toast.makeText(getApplicationContext(),
     "自定義位置Toast", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.CENTER, 0, 0);
   toast.show();

 3.帶圖片效果:

代碼
toast = Toast.makeText(getApplicationContext(),
     "帶圖片的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.完全自定義效果:

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

5.其他線程:

 代碼:
new Thread(new Runnable() {
    public void run() {
     showToast();
    }
   }).start();
