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。
java代码：
"?android:attr/textAppearanceLarge"
"?android:attr/textAppearanceMedium"
"?android:attr/textAppearanceSmall"
使用方法为：
java代码：
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
java代码：
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：
java代码：
<View
android:layout_width="fill_parent"
android:layout_height="1dip"
android:background="?android:attr/listDivider" />
纵向：
java代码：
<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"
