RecyclerView onClick 使用导航抽屉时停止工作（无片段）[重复]

Question

我遇到了this 帖子，其中讨论了如何在不使用片段的情况下创建导航抽屉。撇开我不想使用片段的动机不谈，我现在面临一个问题，即我的RecyclerView 项目的 onClick 事件不再被触发。

TL;DR：如果我从布局 xml 中删除 DrawerLayout 部分，onClick 事件将按预期触发。在我的活动布局 xml 中定义 DrawerLayout 似乎会导致 RecyclerView 的所有事件（例如滚动/单击）停止工作。我的另一个观察结果是包含DrawerLaout 会导致我的RecyclerView 的第一个元素根本不显示。我无法弄清楚是什么导致 onClick 事件被阻止。

以下是我的代码的相关部分：

1. NavigationActivity 将被其他希望显示 Navigation Drawer 的 Activity 扩展

public class NavigationActivity extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener {

    protected void onCreateDrawer() {
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.addDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
    }

    @Override
    public void onBackPressed() {
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.navigation, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @SuppressWarnings("StatementWithEmptyBody")
    @Override
    public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        int id = item.getItemId();

        if (id == R.id.nav_todays_goals) {

        } else if (id == R.id.nav_freetime) {
            Intent intent = new Intent(this,FreeTimeActivity.class);
            startActivity(intent);
        } else if (id == R.id.nav_goaltime) {
            Intent intent = new Intent(this,GoalTimeActivity.class);
            startActivity(intent);
        }

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }

    @Override
    public void setContentView(@LayoutRes int layoutResID)
    {
        super.setContentView(layoutResID);
        onCreateDrawer();
    }
}

2。使用有问题的 RecyclerView 扩展 NavigationActivity 的活动之一（仅显示相关代码）：

public class FreeTimeActivity extends NavigationActivity implements FreeTimeAdapter.FreeTimeAdapterOnClickHandler, LoaderManager.LoaderCallbacks<Cursor> {

    private RecyclerView mRecyclerView;
    private ProgressBar mLoadingIndicator;

    private FreeTimeAdapter mFreeTimeAdapter;

    private int mPosition = RecyclerView.NO_POSITION;

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

        mRecyclerView = (RecyclerView) findViewById(R.id.recyclerview_seasons);
        mLoadingIndicator = (ProgressBar) findViewById(R.id.pb_loading_indicator);
        mFreeTimeAdapter = new FreeTimeAdapter(this, this);
        LinearLayoutManager layoutManager =
                new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);

        mRecyclerView.setLayoutManager(layoutManager);
        mRecyclerView.setHasFixedSize(true);
        mRecyclerView.setAdapter(mFreeTimeAdapter);
        showLoading();
        getSupportLoaderManager().initLoader(FREETIME_LOADER_ID, null, this);

   }

    @Override
    public void onClickFreeTimeListItem(String name) {
        Intent intent = new Intent(this, FreeTimeDetailsActivity.class);
        //TODO uri should be set as freetime_goals rather than goals.
        Uri uri = LifeTimeContract.FreeTimeGoalEntry.CONTENT_URI;
        uri = uri.buildUpon().appendPath(name).build();
        intent.setData(uri);
        intent.putExtra("freezone_name",name);
        startActivity(intent);
    }
}

onClickFreeTimeListItem 方法是在单击mRecyclerView 实例中的项目时应调用的方法。我尝试调试 RecyclerView 使用的FreeTimeAdapter 类，它似乎按预期注册了侦听器，但是稍后单击RecyclerView 中的项目时永远不会调用onClick 方法。以下是FreeTimeAdapter 类的代码：

public class FreeTimeAdapter extends RecyclerView.Adapter<FreeTimeAdapter.FreeTimeAdapterViewHolder> {

    private final Context mContext;

    final private FreeTimeAdapterOnClickHandler mClickHandler;

    /**
     * The interface that receives onClickFreeTimeListItem messages.
     */
    public interface FreeTimeAdapterOnClickHandler {
        void onClickFreeTimeListItem(String name);
    }

    private Cursor mCursor;

    /**
     * Creates a ForecastAdapter.
     *
     * @param context      Used to talk to the UI and app resources
     * @param clickHandler The on-click handler for this adapter. This single handler is called
     *                     when an item is clicked.
     */
    public FreeTimeAdapter(@NonNull Context context, FreeTimeAdapterOnClickHandler clickHandler) {
        mContext = context;
        mClickHandler = clickHandler;
    }

    @Override
    public FreeTimeAdapterViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
        int layoutId = R.layout.freetime_list_items;
        View view = LayoutInflater.from(mContext).inflate(layoutId, viewGroup, false);
        view.setFocusable(true);
        return new FreeTimeAdapterViewHolder(view);
    }

    @Override
    public void onBindViewHolder(FreeTimeAdapterViewHolder freeTimeAdapterViewHolder, int position) {
        mCursor.moveToPosition(position);

        String freeTimeName = mCursor.getString(FreeTimeActivity.INDEX_FREETIME_NAME);
        int id = mCursor.getInt(FreeTimeActivity.INDEX_FREETIME_ID);
        String startTime = mCursor.getString(FreeTimeActivity.INDEX_FREETIME_START_TIME);
        String endTime = mCursor.getString(FreeTimeActivity.INDEX_FREETIME_END_TIME);
        String endDate = mCursor.getString(FreeTimeActivity.INDEX_FREETIME_END_DATE);
        freeTimeAdapterViewHolder.tvFreeTimeName.setText(freeTimeName);
        freeTimeAdapterViewHolder.tvStartTime.setText(startTime);
        freeTimeAdapterViewHolder.tvEndTime.setText(endTime);
        freeTimeAdapterViewHolder.tvEndDate.setText(endDate);
        /*FreeTimeItemDataHolder freeTimeItemDataHolder = new FreeTimeItemDataHolder(id,freeTimeName);*/
        freeTimeAdapterViewHolder.itemView.setTag(R.string.tag_freetime_id,id);
        freeTimeAdapterViewHolder.itemView.setTag(R.string.tag_freetime_name,freeTimeName);


    }


    @Override
    public int getItemCount() {
        if (null == mCursor) return 0;
        return mCursor.getCount();
    }

    void swapCursor(Cursor newCursor) {
        mCursor = newCursor;
        notifyDataSetChanged();
    }

    class FreeTimeAdapterViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

        final TextView tvFreeTimeName;
        final TextView tvStartTime;
        final TextView tvEndTime;
        final TextView tvEndDate;

        FreeTimeAdapterViewHolder(View view) {
            super(view);
            //TODO add additional views to each item in the recyclerview such as delete button etc
            tvFreeTimeName = (TextView) view.findViewById(R.id.tv_freetime_name);
            tvStartTime = (TextView) view.findViewById(R.id.tv_freetime_start_time);
            tvEndTime = (TextView) view.findViewById(R.id.tv_freetime_end_time);
            tvEndDate = (TextView) view.findViewById(R.id.tv_freetime_end_date);
            view.setOnClickListener(this);
        }

        /**
         * This gets called by the child views during a click. We fetch the date that has been
         * selected, and then call the onClickFreeTimeListItem handler registered with this adapter
         *
         * @param v the View that was clicked
         */
        @Override
        public void onClick(View v) {
            int adapterPosition = getAdapterPosition();
            mCursor.moveToPosition(adapterPosition);
            String name = mCursor.getString(FreeTimeActivity.INDEX_FREETIME_NAME);
            mClickHandler.onClickFreeTimeListItem(name);
        }
    }
}

在我介绍NavigationActivity 和相关的抽屉式导航代码之前，相同的代码库运行良好。

Answer 1

您好 ping 实际上我不知道您的代码到底出了什么问题，但您可以查看我的代码，我做了同样的事情，它工作正常
这是包含导航抽屉的基本活动

public class BaseActivity extends AppCompatActivity implements
        NavigationView.OnNavigationItemSelectedListener {

    private NavigationView navigationView;
    private DrawerLayout fullLayout;
    private Toolbar toolbar;
    private ActionBarDrawerToggle drawerToggle;
    private int selectedNavItemId;

    private TextView headerText;
    private TextView pointsTextView;
    private TextView groupTextView;
