setCompoundDrawables与setCompoundDrawablesWithIntrinsicBounds的区别

更换radiobutton中的图片在xml中很好设置,但对于初学者如何在代码中设置还是不容易找的。没法子,通过看原版api找到两个方法,setCompoundDrawables和setCompoundDrawablesWithIntrinsicBounds。
下面交给大家方法。
第一个方法:setCompoundDrawablesWithIntrinsicBounds(Drawable left, Drawable top, Drawable right, Drawable bottom)
api原文为:
Sets the Drawables (if any) to appear to the left of, above, to the right of, and below the text. Use null if you do not want a Drawable there. The Drawables' bounds will be set to their intrinsic bounds.
意思大概就是:可以在上、下、左、右设置图标,如果不想在某个地方显示,则设置为null。图标的宽高将会设置为固有宽高,既自动通过getIntrinsicWidth和getIntrinsicHeight获取。——笔者翻译
1 button = (RadioButton) group.getChildAt(i);2 Resources res = TabTest.this.getResources();3 Drawable myImage = res.getDrawable(R.drawable.home);4 button.setCompoundDrawablesWithIntrinsicBounds(null, myImage, null, null);
如图第一个按钮:
第二种方法:setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom)
api原文为:
Sets the Drawables (if any) to appear to the left of, above, to the right of, and below the text. Use null if you do not want a Drawable there. The Drawables must already have had setBounds(Rect)
called.
意思大概就是:可以在上、下、左、右设置图标,如果不想在某个地方显示,则设置为null。但是Drawable必须已经setBounds(Rect)。意思是你要添加的资源必须已经设置过初始位置、宽和高等信息。——笔者翻译
这下就明白了,这个方法要先给Drawable设置setBounds(x,y,width,height);
x:组件在容器X轴上的起点 y:组件在容器Y轴上的起点 width:组件的长度 height:组件的高度。
如代码:
1 Resources res = TabTest.this.getResources();2 Drawable myImage = res.getDrawable(R.drawable.home);3 myImage.setBounds(1, 1, 100, 100);4 button.setCompoundDrawables(null, myImage, null, null);
只要调整好宽和高。效果也是一样的。这个方法的好处就是不按比例,宽高可以打破原有的大小及比例!如图,我调的y轴有点不对齐。
总结:radiobutton设置不同方位的图标的方法有以上两种,如果想手动设置大小的话就要用setCompoundDrawables,事先要给Drawable设置setBounds。
如果按照原有比例大小显示图片就使用setCompoundDrawablesWithIntrinsicBounds
