我以编程方式添加RadioButtons:
RadioButton radioButton = (RadioButton) inflater.inflate(R.layout.radio_button, null);
...
radioGroup.addView(radioButton);
在RadioButton布局文件中,宽度为match_parent:
android:layout_width="match_parent"
android:layout_height="match_parent"
android:button="@null"
android:drawableLeft="@drawable/check_selector"
android:drawablePadding="@dimen/large"
android:paddingBottom="@dimen/large"
android:paddingTop="@dimen/large"
android:textColor="@drawable/text_selector"
然而,在将它添加到RadioGroup之后,它的宽度是wrap_content:" width:-2"
Timber.e("width: %s", radioGroupReason.getChildAt(radioGroupReason.getChildCount() -1).getLayoutParams().width);
答案 0 :(得分:4)
在添加视图之前使用它:
radioButton.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
