Android: 在 TextView 里使用删除线

以编程的方式添给 TextView 添加删除线：

textview.getPaint().setFlags(Paint.STRIKE_THRU_TEXT_FLAG);

顺便研究下：

TextView.getPaint() ：

// Returns the base paint used for the text.
// Please use this only to consult the Paint's properties and not to change them.
public TextPaint getPaint();

TextPaint：

// TextPaint is an extension of Paint that leaves room
// for some extra data used during text measuring and drawing.
public class TextPaint extends Paint {...}

Paint：

// The Paint class holds the style and color information
// about how to draw geometries, text and bitmaps.
public class Paint extends Object {...}

Paint.setFlags()：

// Set the paint's flags. Use the Flag enum to specific flag values.
// flags: The new flag bits for the paint
public void setFlags (int flags);

 

Paint.STRIKE_THRU_TEXT_FLAG：

// Paint flag that applies a strike-through decoration to drawn text.
// Constant Value: 16 (0x00000010)
public static final int STRIKE_THRU_TEXT_FLAG;
