android:theme
一.android:theme
1.在定义Theme的时候@符号和？符号有何区别？
@符号 表明 我们引用的资源是前边定义过的(或者在前一个项目中或者在Android 框架中)。问号？表明 我们引用的资源的值在 当前的 主题当中定义过
2.常见的主题风格
android:theme="@android:style/Theme.Dialog" 将一个Activity显示为能话框模式 android:theme="@android:style/Theme.NoTitleBar" 不显示应用程序标题栏 android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 不显示应用程序标题栏，并全屏 android:theme="Theme.Light" 背景为白色 android:theme="Theme.Light.NoTitleBar" 白色背景并无标题栏 android:theme="Theme.Light.NoTitleBar.Fullscreen" 白色背景，无标题栏，全屏 android:theme="Theme.Black" 背景黑色 android:theme="Theme.Black.NoTitleBar" 黑色背景并无标题栏 android:theme="Theme.Black.NoTitleBar.Fullscreen" 黑色背景，无标题栏，全屏 android:theme="Theme.Wallpaper" 用系统桌面为应用程序背景 android:theme="Theme.Wallpaper.NoTitleBar" 用系统桌面为应用程序背景，且无标题栏 android:theme="Theme.Wallpaper.NoTitleBar.Fullscreen" 用系统桌面为应用程序背景，无标题栏，全屏 android:theme="Translucent" 半透明 android:theme="Theme.Translucent.NoTitleBar" 半透明、无标题栏 android:theme="Theme.Translucent.NoTitleBar.Fullscreen" 半透明、无标题栏、全屏
二.Activity不显示
2.1.android:theme="@android:style/Theme.NoDisplay"
<activity android:name=".SecondActivity" android:label="SecondActivity" android:theme="@android:style/Theme.NoDisplay" > </activity>
当加载完毕的时候是需要用finish()方法来结束SecondActivity.否则点击返回的时候，会有ANR
2.2.Input事件 无响应
