Java Android RecyclerView项目单击不工作-MVVM

RecyclerView显示了所有数据，但项目单击不起作用。这里我附上我迄今为止所做的工作。为了更好地理解，我删除了所有不必要的代码

这是我的recyclerview项目xml

<data>
    <variable
        name="model"
        type="com.xyz.abc.pojo.EmployeeListWithDesignationSetGet" />

    <variable
        name="viewModel"
        type="com.xyz.abc.viewmodels.EmpListWithDesigViewModel" />

</data>
        <LinearLayout
            android:id="@+id/ll_details"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:clickable="true"
            android:focusable="true"
            android:onClick="@{() -> viewModel.itemClick(model)}">

            <TextView
                android:id="@+id/tv_show_details"
                android:layout_width="70dp"
                android:layout_height="30dp"
                android:text="Show"
                android:textColor="#FFFFFF" />
        </LinearLayout>

我在其中编写click方法的ViewModel类

public class EmpListWithDesigViewModel extends ViewModel {
private MutableLiveData<List<EmployeeListWithDesignationSetGet>> mutableLiveData;
private EmpListWithDesigClickListener listener;
private EmpListWithDesigRepository empListWithDesigRepository;

public void setListener(EmpListWithDesigClickListener listener) {
    this.listener = listener;
}

public void init() {
    if (mutableLiveData != null) {
        return;
    }
    empListWithDesigRepository = EmpListWithDesigRepository.getInstance();
    mutableLiveData = empListWithDesigRepository.getEmpList();
}

public MutableLiveData<List<EmployeeListWithDesignationSetGet>> getEmpList() {
    return mutableLiveData;
}

public void itemClick(EmployeeListWithDesignationSetGet employeeListWithDesignationSetGet) {
    listener.onItemClick(employeeListWithDesignationSetGet);
}
}

公共类EmpListWithDesigViewModel扩展了ViewModel{
私有MutableLiveData MutableLiveData；
具有设计单击侦听器的私人雇员；
私人雇员（含存款人）雇员（含存款人）；
公共void setListener（EmpListWithDesigClickListener侦听器）{
this.listener=listener；
}
公共void init（）{
if（mutableLiveData！=null）{
返回；
}
empListWithDesigRepository=empListWithDesigRepository.getInstance（）；
mutableLiveData=empListWithDesigRepository.getEmpList（）；
}
公共可变LiveData getEmpList（）{
返回可变的livedata；
}
公共无效项单击（EmployeeListWithDesignationSetGet EmployeeListWithDesignationSetGet）{
listener.onItemClick（指定为setget的员工列表）；
}
}

现在在活动中，我正在实现单击界面

public class EmployeeDesignationActivity extends AppCompatActivity implements EmpListWithDesigClickListener {

private RecyclerView mRv_recyclerView;
private List<EmployeeListWithDesignationSetGet> arrayList;
private EmployeeListWithDesigAdapter employeeListWithDesigAdapter;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_employee_designation);

    setViewReferences();
    arrayList = new ArrayList<>();

    employeeListWithDesigAdapter = new EmployeeListWithDesigAdapter(this,arrayList);
    mRv_recyclerView.setAdapter(employeeListWithDesigAdapter);

    EmpListWithDesigViewModel empListWithDesigViewModel = new ViewModelProvider(this,new ViewModelProvider.AndroidViewModelFactory(getApplication())).get(EmpListWithDesigViewModel.class);
    empListWithDesigViewModel.setListener(this);
    empListWithDesigViewModel.init();
    empListWithDesigViewModel.getEmpList().observe(this, new Observer<List<EmployeeListWithDesignationSetGet>>() {
        @Override
        public void onChanged(List<EmployeeListWithDesignationSetGet> employeeListWithDesignationSetGets) {
            arrayList.addAll(employeeListWithDesignationSetGets);
            employeeListWithDesigAdapter.notifyDataSetChanged();
        }
    });
}

private void setViewReferences(){
    mRv_recyclerView = findViewById(R.id.rv_activity_employee_designation);
}



@Override
public void onItemClick(EmployeeListWithDesignationSetGet employeeListWithDesignationSetGet) {
    String phone = employeeListWithDesignationSetGet.getEmpPhone();
    Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" +  phone));
    startActivity(intent);
}

公共类EmployeeDesignationActivity扩展AppCompatActivity实现EmpListWithDesigClickListener{
私人RecyclerView mRv_RecyclerView；
私有列表数组列表；
具有DesigaDapter的私人员工名单；
@凌驾
创建时受保护的void（@Nullable Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity\u employee\u designation）；
setViewReferences（）；
arrayList=新的arrayList（）；
employeeListWithDesigAdapter=新的employeeListWithDesigAdapter（此为arrayList）；
mRv_recyclerView.setAdapter（带有设计适配器的员工列表）；
EmpListWithDesigViewModel EmpListWithDesigViewModel=new ViewModelProvider（这是新的ViewModelProvider.AndroidViewModelFactory（getApplication（））.get（EmpListWithDesigViewModel.class）；
使用desigviewmodel.setListener（此）的emplist；
empListWithDesigViewModel.init（）；
empListWithDesigViewModel.getEmpList（）.observe（这是新的观察者（）{
@凌驾
更改后的公共void（列出employeeListWithDesignationSetGets）{
arrayList.addAll（带有指定集合的EmployeeList）；
带有DesigaDapter.notifyDataSetChanged（）的员工列表；
}
});
}
私有void setViewReferences（）{
mRv\u recyclerView=findViewById（R.id.rv\u活动\u员工\u指定）；
}
@凌驾
public void onItemClick（指定为SetGet的员工列表指定为SetGet的员工列表）{
String phone=employeeListWithDesignationSetGet.getEmpPhone（）；
Intent Intent=新的Intent（Intent.ACTION_DIAL，Uri.parse（“电话：”+phone））；
星触觉（意向）；
}

}

如果我没有提供足够的信息，请原谅，这是我的第一篇SO帖子。谢谢

您应该从

Linearlayout

中删除

android:onClick=“@{（）-viewModel.itemClick（model）}”

。同时添加以下属性

            android:clickable="false"
            android:focusable="false"
            android:focusableInTouchMode="false"

然后，您的项目布局将如下所示：

        <LinearLayout
            android:id="@+id/ll_details"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:clickable="false"
            android:focusable="false"
            android:focusableInTouchMode="false"
            >

            <TextView
                android:id="@+id/tv_show_details"
                android:layout_width="70dp"
                android:layout_height="30dp"
                android:text="Show"
                android:textColor="#FFFFFF" />
        </LinearLayout>

问题已修复。我忘了在recyclerview适配器中绑定viewmodel。

为什么要删除android:onClick=“@{（）-viewmodel.itemClick（model）}”？
