Solution 1:
To get this working you will have to define a custom @BindingAdapter
:
publicclassBindingAdapters {
@BindingAdapter("marginLeftRecord")
publicstaticvoidsetLeftMargin(View view, boolean hasRecord) {
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) view.getLayoutParams();
params.setMargins(
hasRecord ? (int) view.getResources().getDimension(R.dimen.margin1)
: (int) view.getResources().getDimension(R.dimen.margin2)
, 0, 0, 0);
view.setLayoutParams(params);
}
}
Whether you need LinearLayout.LayoutParams
or others depends on the parent of you TextView.
To use this adjust your xml to:
<TextView
android:id="@+id/title_Date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
marginLeftRecord="@{aHomeViewModel.isHaveRecord}" />
Tested and working ;)
