如何在运行时设置按钮的android:drawableTop"属性

How to set property "android:drawableTop" of a button at runtime

推荐答案

使用

button.setCompoundDrawablesWithIntrinsicBounds(left, top, right, bottom);

将 Drawables(如果有)设置为出现在文本的左侧、上方、右侧和下方.如果您不想在那里使用 Drawable，请使用 0.可绘制对象的边界将设置为其内在边界.

Sets the Drawables (if any) to appear to the left of, above, to the right of, and below the text. Use 0 if you do not want a Drawable there. The Drawables' bounds will be set to their intrinsic bounds.

如果你使用

button.setCompoundDrawables(left, top, right, bottom);

将 Drawables(如果有)设置为出现在文本的左侧、上方、右侧和下方.如果您不想在那里使用 Drawable，请使用 null.Drawables 必须已经有 setBounds(Rect) 叫.

Sets the Drawables (if any) to appear to the left of, above, to the right of, and below the text. Use null if you do not want a Drawable there. The Drawables must already have had setBounds(Rect) called.
