Android: 在 TextView 里使用删除线

以编程的方式添给 TextView 添加删除线：

[java] view plaincopy





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

顺便研究下：

TextView.getPaint() ：

[java] view plaincopy





// 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：

[java] view plaincopy





// 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：

[java] view plaincopy





// The Paint class holds the style and color information

// about how to draw geometries, text and bitmaps.

public class Paint extends Object {...}

Paint.setFlags()：

[java] view plaincopy





// 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：

[java] view plaincopy





// Paint flag that applies a strike-through decoration to drawn text.

// Constant Value: 16 (0x00000010)

public static final int STRIKE_THRU_TEXT_FLAG;
