Android:Textview 通过代码设置 Drawable

解决方案

public void  setCompoundDrawables  (Drawable left, Drawable top, Drawable right, Drawable bottom);

类似与在 XML 中

android:drawableLeft="@drawable/icon"

 

使用 TextView 直接调用 setCompoundDrawables() 就可以实现添加 drawable，但是添加完成以后无法显示，查看源码，发现有这么一句话

The Drawables must already have had {@link Drawable#setBounds} called.

1 Drawable drawable = context.getResources().getDrawable(R.drawable
2                         .todo_date_alert_2x);
3 drawable.setBounds(0,0,drawable.getMinimumWidth(),drawable.getMinimumHeight());
4 holder.todoDataALLDate.setCompoundDrawables(drawable, null, null, null);
