Question

通常,各州都有这种冰层分布式。对我的大多数方案来说,我想要把我 but子的背景改变为看不见的背景,并一使用

myButton.setBackgroundColor(Color.TRANSPARENT);

因此,我仍然看着案文,而不是背景。嗣后:

 myButton.setBackgroundColor(Color.GREY);

但是,我ton子只是看着一个带有文字的灰色文字箱,它失去了所有冰纽的编排方式。如何改变它,让 n子感觉到 n子的缺省? 是否使背景看不出不正确?

Answer 1

您可以节省纽芬兰语的提纲,并将它重新定位到后来:

    Drawable originalBackground = button.getBackground();

    button.setBackgroundColor(Color.TRANSPARENT);
    ...
    button.setBackgroundDrawable(originalBackground);

Answer 2

myButton.setBackgroundDrawable(null); Will set it to the default.

Answer 3

Another approach could be 9-patch drawables, which you can use to completely customize your buttons very easily (and they look great, because they are not stretched!) For details see http://developer.android.com/guide/developing/tools/draw9patch.html
