Java if- else 字符串.contains 不起作用错误

Question

如果我输入 entity.about = "phone" 和 test = "phone" 则搜索列表会更新，但如果我输入 entity.about = “this isphone” 和 test = “phone” 则搜索列表不会更新。

public void onSearchConfirmed(final CharSequence text) {
    productsRef = FirebaseDatabase.getInstance().getReference("products");
    searchList.clear();
    final String test = text.toString();
    productsRef.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            for(DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
                ProductEntity entity = postSnapshot.getValue(ProductEntity.class);
                if(entity.about.contains(test) || entity.vendor_address.contains(test)) {
                    searchList.add(entity) ;
                }
            }
        }
    }
}

将代码:entity.about.contains(test)替换为entity.about.toLowerCase.contains(test)
