最近对Dialog的使用比较频繁，在这个过程中发现经常用到的对话框也就几种，个人将其总结为以下几种：

样式一：

代码：

	new AlertDialog.Builder(MainActivity.this)
	.setTitle("AlertDialog")
	// .setIcon(icon)
	.setMessage("text")
	.setPositiveButton("ok", new OnClickListener() {

		public void onClick(DialogInterface dialog,
			int which) {
				// TODO Auto-generated method stub
			}
		}).setNegativeButton("cancel", new OnClickListener() {
		@Override
		public void onClick(DialogInterface dialog,
			int which) {
				// TODO Auto-generated method stub
							}
		}).show();

样式二：

代码：

	final CharSequence[] items = { "Man", "Woman", "Boy", "Girl" };
				 
	new AlertDialog.Builder(MainActivity.this)
	.setTitle("Pick a item")
	.setItems(items, new OnClickListener() {
		public void onClick(DialogInterface dialog, int item) {
			Toast.makeText(getApplicationContext(),
				items[item], Toast.LENGTH_SHORT).show();
			}
	}).show();

样式三：

代码：

	final CharSequence[] items1 = { "Man", "Woman", "Boy", "Girl" };
				 
	new AlertDialog.Builder(MainActivity.this)
	.setTitle("Pick a item")
	.setSingleChoiceItems(items1, -1,
		new OnClickListener() {
		public void onClick(DialogInterface dialog,
			int position) {
		Toast.makeText(
			getApplicationContext(),
				position + "->"
				+ items1[position],
					Toast.LENGTH_SHORT).show();
									
	}).show();

样式四：

代码：

	final CharSequence[] items2 = { "Man", "Woman", "Boy", "Girl" };
	final boolean[] checked = { false, false, false, false };

	new AlertDialog.Builder(MainActivity.this)
	.setTitle("Pick a item")
	.setMultiChoiceItems(items2, checked,
		new OnMultiChoiceClickListener() {
			public void onClick(DialogInterface dialog,
				int position, boolean isChecked) {
					Toast.makeText(
						getApplicationContext(),
							items2[position] + "->"
								+ isChecked,
				Toast.LENGTH_SHORT).show();
									}
	}).show();

样式五：

xml：

命名为layout.xml，置于layout文件夹下

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	        android:layout_height="wrap_content"
	        android:layout_width="wrap_content"
		android:background="#ffffffff" 
		android:orientation="horizontal"
		android:id="@+id/dialog">
	<TextView 
		android:layout_height="wrap_content"
		android:layout_width="wrap_content"
		android:id="@+id/tvname" 
		android:text="姓名：" />
	<EditText 
	    android:layout_height="wrap_content"
	    android:layout_width="wrap_content" 
	    android:id="@+id/etname" 
	    android:minWidth="100dip"/>
</LinearLayout>

java代码：

	LayoutInflater inflater = getLayoutInflater();
	View layout = inflater.inflate(R.layout.layout, null);
	AlertDialog.Builder builder = new AlertDialog.Builder(
		MainActivity.this);
	builder.setTitle("自定义布局").setView(layout)
	.setPositiveButton("确定", null)
	.setNegativeButton("取消", null).show();

如果要获取EditView中的数据可在xml中定义id，然后 获取edit = (EditText)findViewById(id)，通过getText()方法获取
