android 设置中划线 下划线等
android:textAppearance
设置文字外观。如“?android:attr/textAppearanceLargeInverse
”这里引用的是系统自带的一个外观，？表示系统是否有这种外观，否则使用默认的外观。可设置的值如下：textAppearanceButton/textAppearanceInverse/textAppearanceLarge/textAppearanceLargeInverse/textAppearanceMedium/textAppearanceMediumInverse/textAppearanceSmall/textAppearanceSmallInverse
textView.getPaint().setFlags(Paint. UNDERLINE_TEXT_FLAG ); //下划线
textView.getPaint().setAntiAlias(true);//抗锯齿
textview.getPaint().setFlags(Paint. STRIKE_THRU_TEXT_FLAG); //中划线
setFlags(Paint. STRIKE_THRU_TEXT_FLAG|Paint.ANTI_ALIAS_FLAG); // 设置中划线并加清晰
textView.getPaint().setFlags(0); // 取消设置的的划线
