// Calculate ActionBar height
TypedValue tv = new TypedValue();
if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
{
int actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
}
芬兰湾的科特林:
val tv = TypedValue()
if (requireActivity().theme.resolveAttribute(android.R.attr.actionBarSize, tv, true)) {
val actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data, resources.displayMetrics)
}
TypedValue tv = new TypedValue();
if (getActivity().getTheme().resolveAttribute(R.attr.actionBarSize, tv, true))
{
int actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
}
public int getActionBarHeight() {
final TypedArray ta = getContext().getTheme().obtainStyledAttributes(
new int[] {android.R.attr.actionBarSize});
int actionBarHeight = (int) ta.getDimension(0, 0);
return actionBarHeight;
}
The action bar now enhanced to app bar.So you have to add conditional check for getting height of action bar.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
height = getActivity().getActionBar().getHeight();
} else {
height = ((ActionBarActivity) getActivity()).getSupportActionBar().getHeight();
}
application.getAppBar().heightProperty().addListener(new ChangeListener(){
@Override
public void changed(ObservableValue observable, Object oldValue, Object newValue) {
// Take most recent value given here
application.getAppBar.heightProperty.get()
}
});
