Xml文件中设置相信大家都已经非常的熟悉了.
<TextView
android:id="@+id/register_zone"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:drawableRight="@mipmap/lbs_arrow_down"/>
使用代码设置DrawableLeft,Right
第一种方案
Drawable drawable = SwmUIUtils.getDrawable(imgs[position]);
// 确定drawable的位置
drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
// setCompoundDrawables 画的drawable的宽高是按drawable.setBound()设置的宽高，
// 所以才有The Drawables must already have had setBounds(Rect) called.
// 使用之前必须使用Drawable.setBounds设置Drawable的长宽。`
mTaskProgress.setCompoundDrawables(null, null, drawable, null);
第二种方案
setCompoundDrawablesWithIntrinsicBounds(null, null, UIUtils.getDrawable(R.mipmap.up_arrow), null);
setCompoundDrawablesWithIntrinsicBounds是画的drawable的宽高是按drawable固定的宽高，
所以才有The Drawables' bounds will be set to their intrinsic bounds.
即通过getIntrinsicWidth()与getIntrinsicHeight()获得，
