请问如何用代码写出这样的布局界面？

Question

不配置layout这些xml文件。 完全用java代码写出上面的布局， 有人能写出来吗？

Answer 1

顶部的高是40, 底部下是40，中间是自动适应屏幕。 最好是用RelativeLayout的方式，用代码创建。

Answer 2

你在挑战我们的智商吗?想让我们帮你写就说下嘛
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       // setContentView(R.layout.activity_sec);
       RelativeLayout rl = new RelativeLayout(this);
       RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.MATCH_PARENT);
       setContentView(rl,lp);
      
       
       //top view
       RelativeLayout topLayout =new RelativeLayout(this);
       RelativeLayout.LayoutParams topLParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,40);
       topLayout.setBackgroundColor(Color.BLUE);
       topLayout.setId(TOP_ID);
       
       rl.addView(topLayout,topLParams);
       
       //center view
       RelativeLayout centerLayout =new RelativeLayout(this);
       RelativeLayout.LayoutParams centerLParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.MATCH_PARENT);
       
       centerLayout.setBackgroundColor(Color.RED);
       centerLParams.addRule(RelativeLayout.BELOW, TOP_ID);
       
       rl.addView(centerLayout,centerLParams);
       
       //bottom view
       RelativeLayout botLayout =new RelativeLayout(this);
       RelativeLayout.LayoutParams botLParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,40);
       botLayout.setBackgroundColor(Color.YELLOW);
       botLParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM,RelativeLayout.TRUE);
       
       rl.addView(botLayout,botLParams);
       
       
      
            }

            }嘿嘿哈哈呵呵，真是好人啊。

Answer 4

一个LinearLayout同样可以，更加简单

Answer 5

多谢, 对android这些布局,代码写理解不好,

       rl.addView(botLayout,botLParams);
       
       
      
            }
我试了,中间绘错了,你确认这个OK?

我这里显示的是中间部分是到底了， 只是botLayout正好是覆盖在centerLayout上面。
也就是说centerLayout的bottom和botLayout的bottom是一样的，

Answer 9

明明可以用XML解决的问题，非要用代码解决，不是自虐吗？
以前用代码写过拍照用的界面，不是一般的麻烦！2楼的真有耐心啊！

Answer 10

感谢2楼，好了， 有一个属性配错了， 
刚接触android不久，通过这个学到不少布局的使用。
