Use addContentView(int) for replacement

Error message

Use addContentView(int) for replacement

What it means

Same design as the View overload: QMUIBottomSheet cannot host a raw layout-resource content view, so setContentView(int layoutResId) is overridden to always throw IllegalStateException, telling you to use addContentView(int) (or the builder API) instead.

Solutions

1. Inflate the layout yourself and pass the view via addContentView with ConstraintLayout.LayoutParams.
2. Use the QMUIBottomSheet builder (createBottomSheetBuilder().addView(inflater.inflate(R.layout.my_content, null))) instead.
3. Call addContentView(view, ConstraintLayout.LayoutParams) with the inflated view.
4. Refactor helpers to detect QMUIBottomSheet and avoid the forbidden overloads.

Example fix

// before
bottomSheet.setContentView(R.layout.sheet_content); // throws
// after
View view = LayoutInflater.from(context).inflate(R.layout.sheet_content, null);
bottomSheet.addContentView(view, new ConstraintLayout.LayoutParams(
        ConstraintLayout.LayoutParams.MATCH_PARENT,
        ConstraintLayout.LayoutParams.WRAP_CONTENT));

if (sheet instanceof QMUIBottomSheet) {
    View v = LayoutInflater.from(context).inflate(layoutResId, null);
    sheet.addContentView(v, new ConstraintLayout.LayoutParams(MATCH_PARENT, WRAP_CONTENT));
} else {
    sheet.setContentView(layoutResId);
}

boolean supportsSetContentView(Dialog d) { return !(d instanceof QMUIBottomSheet); }

try {
    sheet.setContentView(R.layout.sheet_content);
} catch (IllegalStateException e) {
    View v = LayoutInflater.from(context).inflate(R.layout.sheet_content, null);
    sheet.addContentView(v, new ConstraintLayout.LayoutParams(MATCH_PARENT, WRAP_CONTENT));
}

When it happens

Trigger: Calling bottomSheet.setContentView(R.layout.my_content) on a QMUIBottomSheet.

Common situations: Porting existing Dialog code that inflates a layout resource, or copy-pasted boilerplate from AlertDialog usage.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
