我正在设置为RadioButtons以编程方式添加到RadioGroup的边距,但它失败了:RadioButtons被正确添加,但它们有0个边距......
有人可以帮忙吗?
布局
<RadioGroup android:id="@+id/rg_nav" android:orientation="vertical"
android:layout_width="wrap_content" android:layout_height="wrap_content">
</RadioGroup>
活性
float density = getResources().getDisplayMetrics().density;
rg_nav = (RadioGroup) findViewById(R.id.rg_nav);
LinearLayout.LayoutParams params_rb = new LinearLayout.LayoutParams(
(int)(8*density),
(int)(8*density));
int margin = (int)(6*density);
params_rb.setMargins(margin, margin, margin, margin);
for(String url : product.list_url_pic){
RadioButton radio_btn = new RadioButton(ProductHome.this);
radio_btn.setButtonDrawable(R.drawable.rb_nav);
radio_btn.setId(rb_id++);
rg_nav.addView(radio_btn, params_rb);
}

我不得不替换
LinearLayout.LayoutParams params_rb = new LinearLayout.LayoutParams(
(int)(8*density),
(int)(8*density));
通过
RadioGroup.LayoutParams params_rb = new RadioGroup.LayoutParams(
(int)(8*density),
(int)(8*density));

试试这个:
TableRow.LayoutParams rg_params = new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 3f);
RadioGroup radio_group=new RadioGroup(this);
radio_group.setOrientation(RadioGroup.HORIZONTAL);
radio_group.setLayoutParams(rg_params);
RadioButton dry=new RadioButton(this);
RadioGroup.LayoutParams params_soiled = new RadioGroup.LayoutParams(getBaseContext(), null);
params_soiled.setMargins(10, 0, 10, 0);
dry.setLayoutParams(button_params);

您的代码似乎是正确的。
尝试将LayoutParams
直接应用于按钮
radio_btn.setButtonDrawable(R.drawable.rb_nav);
radio_btn.setId(rb_id++);
rg_nav.addView(radio_btn);
radio_btn.setLayoutParams(params_rb);
