如何在运行时为Button添加边距？

Question

我必须在LinearLayout上添加多个按钮.但我想把这些按钮分开5px.我找不到设置按钮边距的方法.任何的想法？

Answer 1

使用button元素的layout_margin属性.这不起作用吗？

<Button android:layout_margin="5px" (...)/>

编辑

在java中创建按钮时,LayoutParams用于指定边距等.

Button button = new Button();
(....)
params = new LinearLayout.LayoutParams();
params.leftMargin = 5;
(set params as you need)
parent.addView(button, params);

您使用的LayoutParams必须与添加按钮的布局相匹配(请参阅http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html).对于LinearLayout,请使用LinearLayout.LayoutParams并相应地设置*Margin字段.

Answer 2

试试这个:

//Assuming your button is in a LinearLayout as stated
LinearLayout.LayoutParams params = myButton.getLayoutParams();
params.setMargins(0, 0, 0, 0) //left, top, right, bottom
myButton.setLayoutParams(params);
