Answer 1

您需要的只是View.layout(int,int,int,int)方法 Reference说：

public void layout (int l, int t, int r, int b)

Since: API Level 1
Assign a size and position to a view and all of its descendants
This is the second phase of the layout mechanism. (The first is measuring).  
In this phase, each parent calls layout on all of its children to position them.  
This is typically done using the child measurements that were stored  
in the measure pass().

Answer 2

FrameLayout做这类事情并不好，RelativeLayout您可以执行以下操作：

RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)child.getLayoutParams();

layoutParams.leftMargin = x;
layoutParams.topMargin = y;

child.setLayoutParams(layoutParams);
