子控件位置:(XML文件)
LinearLayout中:
android:layout_gravity="center"
RelativeLayout中:

在class里编写控件位置
eg:
RelativeLayout insertLayout = (RelativeLayout)view1.findViewById(R.id.screen);
RelativeLayout.LayoutParams layoutParams= new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);insertLayout .addView(mapScaleBarView,layoutParams);
使得控件居下靠近边缘显示。
