Toast用於提示當前應用的狀態資訊，如網路連線狀態等，一般是顯示一段文字，也可以定製自己的Toast。下面舉例說明：
　

public class MyActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button button1 = (Button) findViewById(R.id.button1);
        Button button2 = (Button) findViewById(R.id.button2);

        //點選顯示圖片
        button1.setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View v) {
				Toast toast = new Toast(MyActivity.this);
				ImageView view = new ImageView(MyActivity.this);
				view.setImageResource(R.drawable.icon);
				toast.setView(view);
				toast.setDuration(Toast.LENGTH_LONG);
				toast.show();	
			}
		});

        //點選顯示文字和圖片
        button2.setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View v) {
				Toast toast = new Toast(MyActivity.this);
				LinearLayout layout = new LinearLayout(MyActivity.this);
				layout.setOrientation(LinearLayout.VERTICAL);

				ImageView view = new ImageView(MyActivity.this);
				view.setImageResource(R.drawable.icon);
				TextView textView = new TextView(MyActivity.this);
				textView.setText("Toast顯示文字和圖片");

				layout.addView(view);
				layout.addView(textView);
				toast.setView(layout);
				toast.show();

			}
		});
    }
}
 

執行結果如下
當點選第一個按鈕後，顯示圖片Toast:
