Android学习笔记--提示信息(Toast)

Toast即是一种提示信息，这个可能来自于 原意 烤吐司，类似于从烤面包机里面弹出吐司的感觉！

使用步骤：

1.调用Toast的静态方法makeText()添加显示文本和时长

2.调用Toast的show()方法进行显示

private Button button1,button2;    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        button1 = (Button)findViewById(R.id.button1);        button2 = (Button)findViewById(R.id.button2);        final int longTime = Toast.LENGTH_LONG;        final int shortTime = Toast.LENGTH_SHORT;        button1.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubToast toast1 = Toast.makeText(getApplicationContext(), "长显示", longTime);toast1.show();}});        button2.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubToast toast2 = Toast.makeText(getApplicationContext(), "短显示", shortTime);toast2.show();}});    }
