Question

我在片段活动上创建了一个RecyclerView的项目。但是当我执行这个项目时显示这样的错误。

java.lang.NoSuchMethodError：android.os.Binder #execTransact（int，int，int，int）#exact at de.robv.android.xposed.XposedHelpers.findMethodExact（XposedHelpers.java:339） at de.robv.android.xposed.XposedHelpers.findAndHookMethod（XposedHelpers.java:176） at de.robv.android.xposed.XposedHelpers.findAndHookMethod（XposedHelpers.java:251）在com.phoneinfo.changerpro.hooks.g.a（未知来源）在com.phoneinfo.changerpro.hooks.MainHook.handleLoadPackage（未知来源） at de.robv.android.xposed.IXposedHookLoadPackage $ Wrapper.handleLoadPackage（IXposedHookLoadPackage.java:34） at de.robv.android.xposed.callbacks.XC_LoadPackage.call（XC_LoadPackage.java:61） at de.robv.android.xposed.callbacks.XCallback.callAll（XCallback.java:106） at de.robv.android.xposed.XposedBridge $ 1.beforeHookedMethod（XposedBridge.java:234） at de.robv.android.xposed.XposedBridge.handleHookedMethod（XposedBridge.java:1550）在android.app.ActivityThread.handleBindApplication（）在android.app.ActivityThread.access $ 1600（ActivityThread.java:154）在android.app.ActivityThread $ H.handleMessage（ActivityThread.java:1378）在android.os.Handler.dispatchMessage（Handler.java:102）在android.os.Looper.loop（Looper.java:135）在android.app.ActivityThread.main（ActivityThread.java:5296） at java.lang.reflect.Method.invoke（Native Method）在java.lang.reflect.Method.invoke（Method.java:372）在com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:912）在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:707）在de.robv.android.xposed.XposedBridge.main（XposedBridge.java:163）

RecyclerView时来自app本身的值没有任何错误。但是，当我尝试从Firebase检索值到应用时，会出现上述错误并且活动已关闭。

可以采取哪些措施来解决这个问题？

我的代码： -

public class DocterList extends Fragment {
    private DatabaseReference dataref;
    private RecyclerView recyclerView;
    private List<Doc> result;
    private DocViewHolder adapter;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.activity_docter_list, container, false);
        Firebase.setAndroidContext(getActivity());
        dataref = FirebaseDatabase.getInstance().getReference().child("Docters");
        result = new ArrayList<>();
        recyclerView = (RecyclerView) v.findViewById(R.id.docter_list);
        recyclerView.setHasFixedSize(true);
        LinearLayoutManager llm = new LinearLayoutManager(getActivity());
        llm.setOrientation(LinearLayoutManager.VERTICAL);
        recyclerView.setLayoutManager(llm);
        FirebaseRecyclerAdapter<Doc,DocViewHolder> adapter=new FirebaseRecyclerAdapter<Doc, DocViewHolder>(
                Doc.class,
                R.layout.view_docter,
                DocViewHolder.class,
                dataref
        ) {
            @Override
            protected void populateViewHolder(DocViewHolder viewHolder, Doc model, int position) {
               viewHolder.setName(model.getName());
                viewHolder.setCity(model.getCity());

            }
        };
        recyclerView.setAdapter(adapter);
        return v;
    }
    public static class DocViewHolder extends RecyclerView.ViewHolder{
        TextView textName,textPlace;
        public DocViewHolder(View itemView) {
            super(itemView);
            textName= (TextView) itemView.findViewById(R.id.t1);
            textPlace= (TextView) itemView.findViewById(R.id.t2);
        }

        public void setName(String name) {
            textName.setText(name);
        }

        public void setCity(String city) {
            textPlace.setText(city);
        }
    }
}

模型Doc类： -

public class Doc {
    String Name,City;

    public Doc() {
    }

    public String getCity() {

        return City;
    }

    public void setCity(String city) {
        City = city;
    }

    public String getName() {
        return Name;
    }

    public void setName(String name) {
        Name = name;
    }

    public Doc(String name, String city) {

        Name = name;
        City = city;
    }
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'

试用此代码

public class DocterList extends Fragment {
    private DatabaseReference dataref;
    private RecyclerView recyclerView;
    private List<Doc> result;
    private DocViewHolder adapter;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.activity_docter_list, container, false);
        Firebase.setAndroidContext(getActivity());
        dataref = FirebaseDatabase.getInstance().getReference().child("Docters");
        result = new ArrayList<>();
        recyclerView = (RecyclerView) v.findViewById(R.id.docter_list);
        recyclerView.setHasFixedSize(true);
        LinearLayoutManager llm = new LinearLayoutManager(getActivity());
        llm.setOrientation(LinearLayoutManager.VERTICAL);
        recyclerView.setLayoutManager(llm);
        FirebaseRecyclerAdapter adapter=new FirebaseRecyclerAdapter<Doc, DocViewHolder>(
                Doc.class,
                R.layout.view_docter,
                DocViewHolder.class,
                dataref
        ) {
            @Override
            protected void populateViewHolder(DocViewHolder viewHolder, Doc model, int position) {
                viewHolder.setName(model.getName());
                viewHolder.setCity(model.getCity());
            }
        };
        recyclerView.setAdapter(adapter);
        return v;
    }
    public static class DocViewHolder extends RecyclerView.ViewHolder{
        TextView textName,textPlace;
        public DocViewHolder(View itemView) {
            super(itemView);
            textName= (TextView) itemView.findViewById(R.id.t1);
            textPlace= (TextView) itemView.findViewById(R.id.t2);
        }

        public void setName(String name) {
            textName.setText(name);
        }

        public void setCity(String city) {
            textPlace.setText(city);
        }
    }
}
