Android预定义样式

1、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"

  2、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"

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

  4、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" />
  5、CheckBox  style="?android:attr/starStyle"

  6、类似标题栏效果的TextView  style="?android:attr/listSeparatorTextViewStyle"

  7、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"
