android - 相对布局中的边距

Question

如何使用代码(不是 XML)在相对布局中设置边距？

我使用这段代码但没有任何反应:

RelativeLayout rlDetail = new RelativeLayout(context);
rlDetail.setBackgroundResource(R.drawable.bg_round);
RelativeLayout.LayoutParams rlDetailParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
rlDetailParams.setMargins(35, 10, 35, 0);
rlDetail.setLayoutParams(rlDetailParams);

Answer 1

试试这个答案 set the absolute position of a view in Android

如上链接所述，您应该使用

TextView tv1 = new TextView(context);

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = needed_margin;
params.topMargin = needed_margin;

// add your textview like this
rl.addView(tv1, params);
