在代码中如果要修改drawableRight设置的图片可以使用API
void android.widget.TextView.setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom)
Drawable可以通过 Drawable rightDrawable = getResources().getDrawable(R.drawable.icon_new); 得到。
但是API提示,setCompoundDrawables() 调用的时候,Drawable对象必须调用setBounds(int left, int top, int right, int bottom)方法,于是我们加一行代码就可以了。
[html] view plain copy
rightDrawable.setBounds(0, 0, rightDrawable.getMinimumWidth(), rightDrawable.getMinimumHeight());
整体代码如下:
[html] view plain copy
Drawable rightDrawable = getResources().getDrawable(R.drawable.icon_new);
rightDrawable.setBounds(0, 0, rightDrawable.getMinimumWidth(), rightDrawable.getMinimumHeight());
tvVersionStatus.setCompoundDrawables(null, null, rightDrawable, null);
