Android：动态添加按钮到布局

Question

我正在尝试向我的buttons动态添加2 relative layout。我希望它看起来像这样：

但目前看起来像这样：

@Abdallah Alaraby的帮助：

    myButton1 = new Button(this);
    myButton1.setBackgroundResource(R.drawable.button);
    myButton1.setText("bttn1");

    myButton2 = new Button(this);
    myButton2.setBackgroundResource(R.drawable.button);
    myButton2.setText("bttn2");


    RelativeLayout rl = (RelativeLayout)findViewById(R.id.rl_dynamic_bttn);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);

lp1.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
lp.addRule(RelativeLayout.RIGHT_OF, myButton2.getId());
rl.addView(myButton1, lp1);
rl.addView(myButton2, lp);
...
...

}

我尝试了各种不同的对齐选项，但似乎没有任何工作。任何人都知道如何让它看起来像第一张照片？

问题可能是my_button2.getId()吗？也许它不被认可？

Answer 1

lp.addRule(RelativeLayout.RIGHT_OF, myButton2.getId());
rl.addView(myButton1, lp);
rl.addView(myButton2, lp);

您对两个按钮使用相同的规则，请尝试以下操作：

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);

myButton1.setId(1)
lp1.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
lp.addRule(RelativeLayout.RIGHT_OF, myButton2.getId());
rl.addView(myButton1, lp1);
rl.addView(myButton2, lp);

如果myButton2没有指定的ID，则默认Id为-1，不起作用。你必须在使用myButton2.getId（）之前使用myButton2.setId（int）
