关于在TextView中设置DrawableLeft的问题

from ：http://ask.csdn.net/questions/903

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

类似调用方法如下:

1.在XML中使用
android:drawableLeft="@drawable/icon"
2.代码中动态变化
Drawable drawable= getResources().getDrawable(R.drawable.drawable);
/// 这一步必须要做,否则不会显示.

drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());

myTextview.setCompoundDrawables(drawable,null,null,null);

也或参考另一个函数

public void setCompoundDrawablesWithIntrinsicBounds (Drawable left,

Drawable top, Drawable right, Drawable bottom)
