我正在尝试使用lambda表达式为SeekBar onProgressChanged
调用一个方法,但我得到了这个异常:

这是布局:

片段代码:
public class FilterFragment extends Fragment
implements FilterContract.View {
private FragmentFilterBinding mViewDataBinding;
private FilterContract.Presenter mPresenter;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_filter, container, false);
mViewDataBinding = FragmentFilterBinding.bind(view);
Filter model = new Filter();
mViewDataBinding.setFilter(model);
return view;
}
}
主讲人:
public class FilterPresenter implements FilterContract.Presenter {
private final FilterContract.View mView;
public FilterPresenter(FilterContract.View mView) {
this.mView = mView;
mView.setPresenter(this);
}
public void start() {
}
@Override
public void maxDistanceChanged(int position) {
}
@Override
public void minRatingChanged(SeekBar seekBar) {
Log.d("minRatingChanged", String.valueOf(seekBar.getProgress()));
}
}
我的代码出了什么问题?
答案 0 :(得分:3)
异常不是由SeekBar
绑定问题造成的android:text="@{filter.minRating}"
此外,我无法确定您在哪里设置filter
。
由于您没有发布br.com.app.model.Filter
的代码,我猜minRating
是一个整数。
因此绑定需要一个字符串资源,在您的情况下为id 0。
只需将minRating
的类型更改为String
。
