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());
