Android - 在1个Activity + XML中有2个RecyclerViews是否可行？

标签： android android-recyclerview onclicklistener

有没有办法在1个XML +活动中拥有2个回收站视图？

当我实现我的适配器的ListItemClickListener时，我遇到了一些麻烦，因为它说'Class HomeActivity必须在'ListItemClickListener'中声明为abstract或实现抽象方法'onListItemClick（MyIssueDao）'。

是否可以与我的2个回收站视图共享方法'onListItemClick'

HomeActivity.java 

public class HomeActivity extends AppCompatActivity implements 
IssuesAdapter.ListItemClickListener, MyIssuesAdapter.ListItemClickListener {

private Context context = HomeActivity.this;
public static RecyclerView.Adapter adapter;
private RecyclerView.LayoutManager layoutManager;
private static RecyclerView recyclerView;
private static RecyclerView myIssuesRecyclerView;
private String currentParent = "";
static View.OnClickListener issueOnClickListener;
static View.OnClickListener myIssueOnClickListener;

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

    // my issues
    myIssuesRecyclerView = (RecyclerView) findViewById(R.id.my_issues_list_recycler_view);
    myIssuesRecyclerView.setHasFixedSize(true);
    myIssuesRecyclerView.setItemAnimator(new DefaultItemAnimator());
    layoutManager = new LinearLayoutManager(this);
    myIssuesRecyclerView.setLayoutManager(layoutManager);


    // issues types
    recyclerView = (RecyclerView) findViewById(R.id.issues_list_recycler_view);
    recyclerView.setHasFixedSize(true);
    layoutManager = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setItemAnimator(new DefaultItemAnimator());

    // TODO - Rest method to receive level types, initially we ask for the first level
    ArrayList<IssueDao> issuesList = new ArrayList<>();
    ArrayList<String> subtypes = new ArrayList<>();
    subtypes.add("Sucursales");
    subtypes.add("ATM");
    IssueDao issue = new IssueDao("0", "Instalaciones", subtypes, "setup", "");
    issuesList.add(issue);
    subtypes = new ArrayList<>();
    subtypes.add("Internet");
    subtypes.add("Móvil");
    subtypes.add("Contact Center");
    issue = new IssueDao("1", "Canales", subtypes, "channels", "");
    issuesList.add(issue);
    subtypes = new ArrayList<>();
    subtypes.add("Ideas y sugerencias");
    issue = new IssueDao("2", "Sugerencias", subtypes, "suggestions", "");
    issuesList.add(issue);

    adapter = new IssuesAdapter(issuesList, HomeActivity.this);

    recyclerView.setAdapter(adapter);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);
    MenuItem saveItem = menu.findItem(R.id.action_save);
    saveItem.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);
    saveItem.setVisible(false);
    return true;
}


@Override
public void onListItemClick(IssueDao issueDao) {
    currentParent = issueDao.getIdParent();
    // TODO - Rest method to receive level types, we ask for the sublevels of the selected issue.
    ArrayList<IssueDao> issuesList = new ArrayList<>();
    ArrayList<String> subtypes = new ArrayList<>();
    subtypes.add("Nacionales");
    subtypes.add("Internacionales");
    IssueDao issue = new IssueDao("3", "Sucursales", subtypes, "setup", "0");
    issuesList.add(issue);
    subtypes = new ArrayList<>();
    subtypes.add("Nacionales");
    subtypes.add("Internacionales");
    issue = new IssueDao("4", "ATM", subtypes, "channels", "0");
    issuesList.add(issue);
    adapter = new IssuesAdapter(issuesList, HomeActivity.this);

    recyclerView.setAdapter(adapter);
    // TODO - If it has no sublevels we show the screen to fill the info of the issue
    //  TODO - delete this
    subtypes = new ArrayList<>();
    if(subtypes.isEmpty()){
        Intent newIssue = new Intent(context, NewIssueActivity.class);
        newIssue.putExtra(IntentEnum.IDTYPEISSUE.getCode(), issueDao.getId());
        startActivity(newIssue);

答案 0 :(得分：0)

您只在 HomeActivity.java 中实现了两个接口中的一个：一个在 IssueDao.java 中为onListItemClick(IssueDao)，另一个在{{1在 MyIssueDao.java 。

此处，您仅实施了onListItemClick(MyIssueDao)。实施另一个，它应该工作。

答案 1 :(得分：0)

以下是答案：

您需要将Thread Started Before Thread Ended Thread Ended After Thread Ended .xml放入LinearLayout并使用ScrollView作为wrap_content RecyclerView's。

layout_height

此外， <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:fillViewport="true"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <TextView android:layout_width="match_parent" android:layout_height="@dimen/list_header" android:background="@color/header" android:gravity="center" android:text="@string/find_friends__already_playing" android:visibility="visible" /> <android.support.v7.widget.RecyclerView android:id="@+id/in_app_friends" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="5dp" android:background="@color/white"/> <TextView android:layout_width="match_parent" android:layout_height="@dimen/list_header" android:background="@color/find_friends__header" android:gravity="center" android:text="@string/find_friends__invite_friends" /> <android.support.v7.widget.RecyclerView android:id="@+id/friends_to_invite" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/white"/> </LinearLayout> </ScrollView> 和RecyclerView存在错误，因此您必须使用自定义布局管理器。 看看这篇文章：[如何让WRAP_CONTENT在RecyclerView上工作] [1]

在您的java代码中，设置第二个wrap_content 它对我有用!!!
