找不到属性的setter

找不到属性的setter

本文介绍了Android数据绑定:找不到属性的setter的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

不知道它是如何工作的,但根据这篇文章可以通过使用不同的命名空间来绑定特定的监听器。



我想用一个searchview做同样的事情,并将QueryTextListener绑定到它,但是我收到以下错误:

 找不到属性bind:setOnQueryTextListener
的参数类型为android.widget.SearchView.OnQueryTextListener的setter。

我在ViewModel中所做的:

  public class MembersFragmentViewModel extends BaseObservable {

private Context context;
private MembersAdapter适配器;
private RecyclerView recyclelerView;

public MemberFragmentViewModel(Context context,MembersAdapter adapter,RecyclerView recyclelerView){
this.context = context;
this.adapter = adapter;
this.recyclerView = recyclelerView;
}

public SearchView.OnQueryTextListener getQueryTextListener(){
返回新的SearchView.OnQueryTextListener(){
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}

@Override
public boolean onQueryTextChange(String query){
列表< Contact> filteredModelList = filter(adapter.getContacts(),query);
adapter.animateTo(filteredModelList);
if(recyclelerView!= null)
recyclelerView.scrollToPosition(0);
返回true;
}
};
}
//代码...

而xml: p>

我的命名空间在布局标签中声明如下:

  xmlns: bind =http://schemas.android.com/apk/res-auto

而我的SearchView:

 < android.support.v7.widget.SearchView android:id =@ + id / searchview
android:layout_width =match_parent
android:layout_height =40dp

android:background =@ drawable / rounded_search_view_background
bind:setOnQueryTextListener =@ {viewModel .QueryTextListener}>

< /android.support.v7.widget.SearchView>

这是我的数据标签:

 < data> 
< variable
name =viewModel
type =mypackagename.viewmodel.members.MembersFragmentViewModel/>
< / data>

非常感谢任何线索!

解决方案

在我的情况下,答案只是一个错误的包名称。



我的SearchView在xml中被声明为具有以下包名称: / p>

  android.support.v7.widget.SearchView 

我在ViewModel中使用的包是

  android.widget.SearchView 


Not sure how it works but according to this post it's possible to bind specific listener by using different namespaces.

I wanted to do the same thing with a searchview and bind a QueryTextListener to it but I get the following error :

Cannot find the setter for attribute 'bind:setOnQueryTextListener'
with parameter type android.widget.SearchView.OnQueryTextListener.

What I did in my ViewModel :

public class MembersFragmentViewModel extends BaseObservable {

    private Context context;
    private MembersAdapter adapter;
    private RecyclerView recyclerView;

    public MembersFragmentViewModel(Context context, MembersAdapter adapter, RecyclerView recyclerView) {
        this.context = context;
        this.adapter = adapter;
        this.recyclerView = recyclerView;
    }

    public SearchView.OnQueryTextListener getQueryTextListener(){
        return new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }

            @Override
            public boolean onQueryTextChange(String query) {
                List<Contact> filteredModelList = filter(adapter.getContacts(), query);
                adapter.animateTo(filteredModelList);
                if(recyclerView != null)
                    recyclerView.scrollToPosition(0);
                return true;
            }
        };
    }
    //Code ...

And the xml :

My namespace is declared in the layout tag like this :

xmlns:bind="http://schemas.android.com/apk/res-auto"

And my SearchView :

<android.support.v7.widget.SearchView android:id="@+id/searchview"
        android:layout_width="match_parent"
        android:layout_height="40dp"

        android:background="@drawable/rounded_search_view_background"
        bind:setOnQueryTextListener="@{viewModel.QueryTextListener}">

</android.support.v7.widget.SearchView>

This is my data tag :

<data>
   <variable
       name="viewModel"
       type="mypackagename.viewmodel.members.MembersFragmentViewModel"/>
</data>

Many thanks for any clue !

解决方案

In my case the answer was just a wrong package name.

My SearchView was declared in xml with the following package name :

android.support.v7.widget.SearchView

And the package I used in the ViewModel was

android.widget.SearchView
