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@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(getApplicationContext(), "访问OSC的网页", 0).show();}});builder.setNeutralButton("隐藏", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {}});builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic 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DialogAlertDialog dialog = builder.create();// 4 显示Dialogdialog.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() {@Overridepublic 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() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(getApplicationContext(), items[which], 0).show();}});

4.多选框的Dialog

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() {@Overridepublic void onClick(DialogInterface dialog, int which, boolean isChecked) {Toast.makeText(getApplicationContext(), items[which] + isChecked, 0).show();}});

5.进度条的dialog

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() {@Overridepublic void onClick(DialogInterface dialog, int which) {}});progressDialog.show();progressDialog.setProgress(50);// 设置进度条的当前刻度

注意的是Dialog是activity的一个控件，弹出Dialog的时候，activity是不会失去焦点的，也就是说activity不会调用onPause()方法
