绘制资源类型 (Drawable)类中有个setLevel()的方法他的作用是选择某个级别中可绘制的资源 有时候，我们为了在一个image view中显示不同的图片，往往会使用： if (条件1) { image.setBackground(R.id.xxx1); } else if (条件2) { image.setBackground(R.id.xxx2); } ... 可以使用setLevel（）更好的实现 在xml中： <?xml version="1.0" encoding="utf-8"?> <level-listxmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/status_off" android:maxLevel="0"/> <item android:drawable="@drawable/status_on" android:maxLevel="1"/> </level-list> 调用setLevel显示不同的图片 在java中： leftPoint.getDrawable().setLevel(1); viewPager.setOnPageChangeListener(new ViewPager

问题 I want to create a drawable which looks like this. and I know how to create the image background but even after searching, I am unable to find how to give text to that drawable file. Is there any way that the drawable file is exactly same containing the text as well? I cant use textview because its a tab and I need drawables to set as background resource (thats what I know, please correct me if I am wrong.). So I want a drawable file which I can set as background. 回答1: Yes you can do that.
