Description
Description: expand title width is short when some menu exists, see this picture
Expected behavior: expand title width is same with screen
Source code:
// update some codes from catalog: TopAppBarCollapsingMultilineDemoFragment.java
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater menuInflater) {
// update menu file to display more icons in toolbar
menuInflater.inflate(R.menu.cat_topappbar_menu, menu);
super.onCreateOptionsMenu(menu, menuInflater);
}
@Override
public void onPrepareOptionsMenu(@NonNull Menu menu) {
super.onPrepareOptionsMenu(menu);
// CollapsingToolbarLayout collapsingToolbarLayout =
// requireView().findViewById(R.id.collapsingtoolbarlayout);
// @SuppressWarnings("RestrictTo")
// int maxLines = collapsingToolbarLayout.getMaxLines();
// for (int i = 0; i < linesMap.size(); i++) {
// int value = linesMap.valueAt(i);
// int itemId = linesMap.keyAt(i);
// MenuItem item = menu.findItem(itemId);
// CharSequence title = getString(R.string.menu_max_lines, value);
// if (maxLines == value) {
// SpannableString spannable = new SpannableString(title);
// spannable.setSpan(new ForegroundColorSpan(colorPrimary), 0, title.length(), 0);
// title = spannable;
// }
//
// item.setTitle(title);
// }
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// CollapsingToolbarLayout collapsingToolbarLayout =
// requireView().findViewById(R.id.collapsingtoolbarlayout);
// collapsingToolbarLayout.setMaxLines(linesMap.get(item.getItemId(), 1));
return super.onOptionsItemSelected(item);

Research direction
Start by reproducing the behavior in TopAppBarCollapsingMultilineDemoFragment.java with the cat_topappbar_menu menu and the listed Material Library versions. Inspect CollapsingToolbarLayout's title layout when toolbar menu items are present; done means the expanded title can use the full screen width while the menu remains visible.
