我以编程方式在相对布局中创建了 2 个按钮。我不希望按钮之间没有边距,并试图通过使用“setmargin”来实现这一点,但失败了。下面是代码。
//creating the relative layout
RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
//creating buttons
Button button1 = new Button(this);
button1.setId(R.id.button1);
RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(
SCR_W/2,
RelativeLayout.LayoutParams.WRAP_CONTENT);//SCR_W is the device screenwidth
params1.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
params1.addRule(RelativeLayout.ALIGN_PARENT_TOP);
params1.setMargins(0, 0, 0, 0);
button1.setLayoutParams(params1);
relativeLayout.addView(button1);
Button button2 = new Button(this);
button2.setId(R.id.button2);
RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams(
SCR_W/2,
RelativeLayout.LayoutParams.WRAP_CONTENT);
params2.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
params2.addRule(RelativeLayout.BELOW, button1.getId());
params2.setMargins(0, 0, 0, 0);
button2.setLayoutParams(params2);
relativeLayout.addView(button2);
//setting the relative layout as the contentview
setContentView(relativeLayout, rlp);
提前致谢..
最佳答案
我试过你的代码,对我来说工作正常,
两个按钮的距离为 0。要检查它,只需为每个按钮设置不同的颜色,您就会看到它们在一起。
button1.setBackgroundColor(Color.BLUE);
button2.setBackgroundColor(Color.RED);
