Android中几种常用的话框

 1.普通对话框：

 Builder alert=new AlertDialog.Builder(MainActivity.this);
 alert.setTitle("提示");
 alert.setMessage("普通对话框");
 alert.setPositiveButton("确定", null);
 alert.show();

 2.自定义对话框：

 LayoutInflater layout=LayoutInflater.from(MainActivity.this);//设置布局文件的过滤是从MainActivity中进行的
 View view=layout.inflate(R.layout.custmer, null);//建一个View 对象用来存放自定义的布局文件，这里的R.layout.custmer就是自定义的文件布局
 Builder customer=new AlertDialog.Builder(MainActivity.this);
 customer.setView(view);//通过此方法可以将自定义的布局加载到对话框中
 customer.setTitle("提示");
 customer.setMessage("自定义对话框");
 customer.setPositiveButton("确定", null).create();
 customer.show();

 3.类似单选按钮形式的对话框：

 Builder customer=new AlertDialog.Builder(MainActivity.this);
 customer.setTitle("提示");
 customer.setMessage("自定义对话框");
 customer.setSingleChoiceItems(new String[]{"a","b","c"}, 0, new OnClickListener(){
                 public void onClick(DialogInterface arg0, int arg1) {
                     Toast.makeText(MainActivity.this, "你选择了"+arg1+"项", Toast.LENGTH_LONG).show();
                 }

             });
 customer.setPositiveButton("确定", null).create();
 customer.show();

 4.多选类型的对话框
 Builder customer=new AlertDialog.Builder(MainActivity.this);
 customer.setTitle("提示");
 customer.setMessage("自定义对话框");
 设置为多选对话框，前面的是选项，会面对应的是，是否处于选中状态
 customer.setMultiChoiceItems(new String[]{"a","b","c","d"}, new boolean[]{true,false,false,false}, new OnMultiChoiceClickListener(){
                 public void onClick(DialogInterface arg0, int arg1, boolean arg2)
                 {
                     Toast.makeText(MainActivity.this, "你选择了"+arg1+"项", Toast.LENGTH_LONG).show();
                 }

             });
 customer.show();

 5.进度对话框：
     1）。ProgressDialog progress=ProgressDialog.show(MainActivity.this, "安装进度", "正在安装");
52 第二个参数是：提示的标题；第三个参数是：messge信息
53
     2）。也可以这样写：
 ProgressDialog dialog=new ProgressDialog(MainActivity.this);
             dialog.setButton2("确定", new OnClickListener()){

                 @Override
                 public void onClick(DialogInterface arg0, int arg1) {
                     // TODO Auto-generated method stub

                 }

             });
 dialog.setTitle("安装进度");
 dialog.setMessage("正在安装");
 dialog.setIndeterminate(false);//设置进度为不明确类型的
 dialog.setSecondaryProgress(progress);//设置进度值的二次进度
 dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL)//设置为水平进队条
 dialog.show();

 6.时间选择对话框：
     calendar=Calendar.getInstance();
         year=calendar.get(Calendar.YEAR);
         month=calendar.get(Calendar.MONTH);
         day=calendar.get(Calendar.DAY_OF_MONTH);
         minute=calendar.get(Calendar.MINUTE);
         hour=calendar.get(Calendar.HOUR);
 new TimePickerDialog(this, new OnTimeSetListener(){

                 @Override
                 public void onTimeSet(TimePicker arg0, int arg1, int arg2) {
                     calendar.set(year,month,day,hour,minute);
                 }}, hour, minute, false).show();

 7.日期选择对话框：
 new DatePickerDialog(this,new OnDateSetListener(){
                 public void onDateSet(DatePicker arg0, int arg1, int arg2,
                         int arg3) {
                     calendar.set(year,month,day);
                 }

             },year,month,day).show();
