设计UI的时候,发现TextView在布局上占用的高度和属性textSize的大小不一样,要比textSize要来的大(例如textSize="12dp",实际的高度大概有14-16dp)。
仔细看的话会发现文字的上方和下方都留有空白,这严重影响布局的效果。
经过调研,发现TextView有一个属性,通过修改这个属性能够解决这个问题。
android:includeFontPadding Leave enough room for ascenders and descenders instead of using the font ascent and descent strictly. (Normally true). Must be a boolean value, either "true" or "false". This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type. This corresponds to the global attribute resource symbol includeFontPadding. Related Methods setIncludeFontPadding(boolean)
