Android 预定义样式

字体大小

对于能够显示文字的控件（如TextView EditText RadioButton Button CheckBox Chronometer等等），你有时需要控制字体的大小。Android平台定义了三种字体大小。

"?android:attr/textAppearanceLarge"

"?android:attr/textAppearanceMedium"

"?android:attr/textAppearanceSmall"

使用方法为：

android:textAppearance="?android:attr/textAppearanceLarge" 
android:textAppearance="?android:attr/textAppearanceMedium" 
android:textAppearance="?android:attr/textAppearanceSmall"

或

style="?android:attr/textAppearanceLarge" 
style="?android:attr/textAppearanceMedium" 
style="?android:attr/textAppearanceSmall"

字体颜色

android:textColor="?android:attr/textColorPrimary" 
android:textColor="?android:attr/textColorSecondary" 
android:textColor="?android:attr/textColorTertiary" 
android:textColor="?android:attr/textColorPrimaryInverse" 
android:textColor="?android:attr/textColorSecondaryInverse"

ProgressBar

style="?android:attr/progressBarStyleHorizontal" 
style="?android:attr/progressBarStyleLarge" 
style="?android:attr/progressBarStyleSmall" 
style="?android:attr/progressBarStyleSmallTitle"

分隔符

横向：

<View android:layout_width="fill_parent" 
      android:layout_height="1dip" 
      android:background="?android:attr/listDivider" />

纵向：

<View android:layout_width="1dip" 
      android:layout_height="fill_parent" 
      android:background="?android:attr/listDivider" />

CheckBox

style="?android:attr/starStyle"

类似标题栏效果的TextView

style="?android:attr/listSeparatorTextViewStyle"

其它有用的样式

android:layout_height="?android:attr/listPreferredItemHeight"

android:paddingRight="?android:attr/scrollbarSize"

style="?android:attr/windowTitleBackgroundStyle"

style="?android:attr/windowTitleStyle"

android:layout_height="?android:attr/windowTitleSize"

android:background="?android:attr/windowBackground"
