如何在android中动态设置弹出窗口的Margin Left，Margin top，Margin right和Margin Bottom对齐方式

Question

我目前正在做一个包含名为mypopup的弹出窗口的Android应用程序。它包含一个图像按钮和四个文本视图。我想动态地将弹出窗口与边距顶部，边距底部，边距左边和边距右边的参数对齐。在我的代码中，setmargin方法无法正常工作..请任何人帮我这样做...

Answer 1

这取决于您使用的是哪种布局。下面的示例将RelativeLayout放在LinearLayout中。

LinearLayout linearLayoutParent;
RelativeLayout relativeLayout;

RelativeLayout.LayoutParams margin = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,
                RelativeLayout.LayoutParams.WRAP_CONTENT);
margin.setMargins(0, 0, 0, 7); //7px bottom margin

//create the linear and the relative layouts

//...add other stuff here...

// Add view with its margins
linearLayoutParent.addView(relativeLayout, margin);

Answer 2

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
lp.setMargins(0,0, 5, 0);
