android 设置textview 左边,Android设置图片在TextView上、下、左、右

一种是在布局文件中的设置

android:drawablePadding="5dp"//图片与文案距离

android:drawableBottom="@drawable/icon_search"

android:drawableLeft="@drawable/icon_search"

android:drawableTop="@drawable/icon_search"

android:drawableRight="@drawable/icon_search"

但有时我们根据一些条件来设置显示的位置，这就要用到第二种动态代码设置

setCompoundDrawables(left, top, right, bottom)；

setCompoundDrawablesWithIntrinsicBounds(left, top, right, bottom)；

设置Drawable显示在text的左、上、右、下位置

两者区别：

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。

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
