Android中的各种Dialog

   下面是自己总结的Android常用的几种Dialog：

1.AlertDialog android中功能最丰富，用途最广的对话框。

 // 1 创建一个Builder     AlertDialog.Builder builder = new AlertDialog.Builder(this);   // 2 给Builder设置属性   builder.setTitle("Java培训");// 设置Dialog的标题    builder.setMessage("访问OSC的网页");// 设置Dialog的信息    builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {// 设置确定按钮         @Override       public void onClick(DialogInterface dialog, int which) {        Toast.makeText(getApplicationContext(), "访问OSC的网页", 0).show();       }      });    builder.setNeutralButton("隐藏", new DialogInterface.OnClickListener() {       @Override     public void onClick(DialogInterface dialog, int which) {     }    });    builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {     @Override     public void onClick(DialogInterface dialog, int which) {     }    });   //从上我们可以看出Dialog的按钮一般分为了三种，确定builder.setPositiveButton(),隐藏builder.setNeutralButton,取消builder.setNegativeButton   // 3 创建Dialog    AlertDialog dialog = builder.create();       // 4 显示Dialog    dialog.show();

2.ListDialog,设置选项的时候用如下代码：

final String[] items = { "java", "donet", "php" };  builder.setItems(items, new DialogInterface.OnClickListener() {       @Override     public void onClick(DialogInterface dialog, int which) {      Toast.makeText(getApplicationContext(), items[which], 0).show();     }    });

3.singleItemDialog，这样子能够让选项以单选框的样式呈现出来：

builder.setSingleChoiceItems(items, 2, new DialogInterface.OnClickListener() {       @Override     public void onClick(DialogInterface dialog, int which) {      Toast.makeText(getApplicationContext(), items[which], 0).show();     }    });

final String[] items = { "java", "donet", "php" };    final boolean[] checkedItems = new boolean[] { true, false, false };    AlertDialog.Builder builder = new AlertDialog.Builder(this);    builder.setTitle("选择语言");    builder.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {       @Override     public void onClick(DialogInterface dialog, int which, boolean isChecked) {      Toast.makeText(getApplicationContext(), items[which] + isChecked, 0).show();     }    });

ProgressDialog progressDialog = new ProgressDialog(this);    progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);// 设置为水平进度条    progressDialog.setTitle("正在下载。。。");    progressDialog.setMax(100);// 设置进度条的最大值    progressDialog.setCancelable(false);// 设置回退键失效      progressDialog.setButton("取消", new DialogInterface.OnClickListener() {       @Override     public void onClick(DialogInterface dialog, int which) {     }    });    progressDialog.show();    progressDialog.setProgress(50);// 设置进度条的当前刻度
