如何在Android中動態設置彈出窗口的左邊距，頂部右邊距，右邊距右邊距和底部底部對齊

Question

我目前正在做一個包含名為mypopup的彈出窗口的android應用程序。 它包含一個圖像按鈕和四個文本視圖。 我想用上邊距，下邊距，左邊距和右邊距右邊的參數動態對齊彈出窗口。

Answer 1

這取決於您使用的布局。 下面的示例將RelativeLayout放置在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);
