Android数据绑定layout_width和layout_height

在Java中

@BindingAdapter("layout_height")public static void setLayoutHeight(View view, float height) {    LayoutParams layoutParams = view.getLayoutParams();    layoutParams.height = height;    view.setLayoutParams(layoutParams);}

在您的XML中

app:layout_height="@{ viewModel.isBig ? @dimen/dp_20 : @dimen/dp_5 }"

像这样导入应用
