AlertDialog.Builder builder = new AlertDialog.Builder(this);        builder.setTitle("单选对话框");        //builder.setMessage("message");        //这行代码不能加,加了就不显示单选的内容了        final String[] itemNum = {"1", "2", "3"};        //参数1:单选的内容的数组        //参数2:默认选中的是哪一项,-1代表都不选中        //参数3:设置监听器        builder.setSingleChoiceItems(itemNum, -1, new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                Toast.makeText(DialogActivity.this, itemNum[which], Toast.LENGTH_SHORT).show();                //隐藏对话框                dialog.dismiss();            }        });        builder.create().show();

//创建Calendar实例对象        Calendar calendar = Calendar.getInstance();        //创建DatePickerDialog并显示        //参数1:上下文        //参数2:日期选择回调        //参数3,4,5 默认显示的年月日        new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {            @Override            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {                Toast.makeText(DialogActivity.this,                        year+"-"+(month+1)+"-"+dayOfMonth                        , Toast.LENGTH_SHORT).show();            }        },calendar.get(Calendar.YEAR)        ,calendar.get(Calendar.MONTH) //月份默认是 0-11        ,calendar.get(Calendar.DAY_OF_MONTH)).show();

时间选择对话框

Calendar calendar = Calendar.getInstance();        new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {            @Override            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {                Toast.makeText(DialogActivity.this,                        hourOfDay+":"+minute                        , Toast.LENGTH_SHORT).show();            }        },calendar.get(Calendar.HOUR_OF_DAY)        ,calendar.get(Calendar.MINUTE)        ,true).show();

final ProgressDialog pd = new ProgressDialog(this);        pd.setTitle("进度");        pd.setMessage("loading...");        //设置进度条为水平风格        pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);        //设置最大进度值        pd.setMax(100);        //创建子线程 模拟下载进度        new Thread(new Runnable() {            @Override            public void run() {                for (int i =0;i<=100;i++) {                    //休眠50毫秒,模拟下载效果                    SystemClock.sleep(50);                    //设置当前进度                    pd.setProgress(i);                }                //关闭进度条对话框                pd.dismiss();                //google不允许开发者在子线程中修改UI,                //所以让Toast代码运行在主线程中                //通过runOnUiThread方法实现                runOnUiThread(new Runnable() {                    @Override                    public void run() {                        Toast.makeText(DialogActivity.this, "完成", Toast.LENGTH_SHORT).show();                    }                });            }        }).start();//开启线程        //显示进度条对话框        pd.show();
