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. Toast.LENGTH_SHORT).show();

2.自定义显示位置效果

代码

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

3.带图片效果

代码

1. toast = Toast.makeText(getApplicationContext(),
2. "带图片的Toast", Toast.LENGTH_LONG);
3. toast.setGravity(Gravity.CENTER, 0, 0);
4. LinearLayout toastView = (LinearLayout) toast.getView();
5. ImageView imageCodeProject = new ImageView(getApplicationContext());
6. imageCodeProject.setImageResource(R.drawable.icon);
7. toastView.addView(imageCodeProject, 0);
8. toast.show();

4.完全自定义效果

代码

1. LayoutInflater inflater = getLayoutInflater();
2. View layout = inflater.inflate(R.layout.custom,
3. (ViewGroup) findViewById(R.id.llToast));
4. ImageView image = (ImageView) layout
5. .findViewById(R.id.tvImageToast);
6. image.setImageResource(R.drawable.icon);
7. TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);
8. title.setText("Attention");
9. TextView text = (TextView) layout.findViewById(R.id.tvTextToast);
10. text.setText("完全自定义Toast");
11. toast = new Toast(getApplicationContext());
12. toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);
13. toast.setDuration(Toast.LENGTH_LONG);
14. toast.setView(layout);
15. toast.show();

5.其他线程

代码

1. new Thread(new Runnable() {
2. public void run() {
3. showToast();
4. }
5. }).start();

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。
