Toast温馨小提示

例子一：
Java代码
Button btn2 = (Button)findViewById(R.id.button2);
    btn2.setOnClickListener(new OnClickListener() {
    @Override
        public void onClick(View v) {
LayoutInflater vi = (LayoutInflater)
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View view = vi.inflate(R.layout.main, null);
            TextView tv = (TextView)view.findViewById(R.id.textView);
tv.setText("文本小提示");
Toast toast = new Toast(ToastView.this);
toast.setView(view);
toast.setDuration(Toast.LENGTH_SHORT);
toast.show();
}
});

例子二：
Java代码
super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    RadioGroup r = (RadioGroup)findViewById(R.id.radioGroup1);
    r.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int cheId) {
            //cheId为点击的radio的id
            Toast.makeText(ActivityTest.this, "test", Toast.LENGTH_SHORT).show();
        }
});

PS：ActivityTest.this是类本身，比如例二是指在ActivityTest引用的方法
