程序实现线性布局相关1、

 

LinearLayout linearLayout_content = new LinearLayout(mContext);
			linearLayout_content.setPadding(38, 0, 5, 0);
			linearLayout_content.setOrientation(LinearLayout.VERTICAL);
			linearLayout_content.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
