编程创建于Android的一个RelativeLayout的 [英] Programmatically creating a RelativeLayout in Android

问题描述

我加入两个按钮的UI中，但它们出现在彼此的顶部。我希望他们能够彼此相邻出现。那我在这code失踪？

  m_btnCrown =新的ImageButton（本）;
m_btnCrown.setImageResource（R.drawable.king_crown_thumb）;
m_btnCrown.setAlpha（100）;

RelativeLayout.LayoutParams LP =新RelativeLayout.LayoutParams（
    RelativeLayout.LayoutParams.WRAP_CONTENT，RelativeLayout.LayoutParams.WRAP_CONTENT）;
lp.addRule（RelativeLayout.ALIGN_PARENT_TOP）;


addContentView（m_btnCrown，LP）;


m_btnMonkey =新的ImageButton（本）;
m_btnMonkey.setImageResource（R.drawable.monkey_small）;
m_btnMonkey.setAlpha（100）;

LP =新RelativeLayout.LayoutParams（
    RelativeLayout.LayoutParams.WRAP_CONTENT，RelativeLayout.LayoutParams.WRAP_CONTENT）;
lp.addRule（RelativeLayout.ALIGN_PARENT_TOP）;
lp.addRule（RelativeLayout.RIGHT_OF，m_btnCrown.getId（））;

addContentView（m_btnMonkey，LP）;
 

解决方案

在找到<一个答案href="http://stackoverflow.com/questions/2305395/laying-out-views-in-relativelayout-programmatically/2499721#2499721">Laying在RelativeLayout的意见编程

我们应该使用SETID明确设定的ID（）。只有这样，RIGHT_OF规则是有意义的。

另外一个错误，我所做的是，重用控件之间的LayoutParams对象。我们应该为每个控件创建新的对象。

I'm adding two buttons to the UI, but they appear on top of one another. I want them to appear next to each other. What am I missing in this code?

m_btnCrown = new ImageButton(this);
m_btnCrown.setImageResource(R.drawable.king_crown_thumb);
m_btnCrown.setAlpha(100);

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);


addContentView(m_btnCrown, lp);


m_btnMonkey = new ImageButton(this);
m_btnMonkey.setImageResource(R.drawable.monkey_small);
m_btnMonkey.setAlpha(100);

lp = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
lp.addRule(RelativeLayout.RIGHT_OF, m_btnCrown.getId());   

addContentView(m_btnMonkey, lp);

解决方案

Found the answer in Laying out Views in RelativeLayout programmatically

We should explicitly set id's using setId(). Only then, RIGHT_OF rules make sense.

Another mistake I did is, reusing the layoutparams object between the controls. We should create new object for each control
