Question

我正在尝试实现与Todoits应用程序中类似的效果，您可以在其中单击FAB，它显示了一个用于添加新任务的浮动弹出窗口。外观如下：

我最接近实现的方法是：

它快要出现了，但是我希望弹出窗口在键盘上方大约10dp，然后将回收查看器滚动到最后一个项目，但我无法到达那里：/当前，弹出窗口居中。

在将弹出窗口添加到屏幕底部并设置android：windowSoftInputMode =“ adjustResize”之前，我已经尝试过了，但这也使我的底部导航也移到了键盘上方。将windowsSoftInputMode设置为panAdjust会删除工具栏和列表中的少量项目。

您对如何获得与Todoist中的效果相似的任何建议吗？也许有一个DialogFragment？

以下是我当前的代码（导航栏实现仍未完成）： MainActivity：

public class MainActivity extends AppCompatActivity {
  private WorkoutsListFragment workoutsListFragment;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar myToolbar = findViewById(R.id.my_toolbar);
    setSupportActionBar(myToolbar);
    ActionBar actionBar = getSupportActionBar();

    this.workoutsListFragment = new WorkoutsListFragment();
    getSupportFragmentManager()
        .beginTransaction()
        .add(R.id.main_layout, workoutsListFragment)
        .commit();
  }
}

WorkoutListFragment：

public class WorkoutsListFragment extends Fragment
    implements View.OnClickListener, WorkoutListViewHolderInterface {

  private RecyclerView recyclerView;
  private WorkoutListRecycleViewAdapter recycleViewAdapter;
  private AddBoxView addBoxView;
  private FloatingActionButton actionButton;
  private InputMethodManager imm;
  private WorkoutViewModel workoutViewModel;
  private boolean addBoxStatus;

  public WorkoutsListFragment() {}

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.addBoxStatus = false;
   //Irrelevant code removed (Dagger 2 DI)

    this.workoutViewModel =
        ViewModelProviders.of(this, workoutViewModelFactory).get(WorkoutViewModel.class);

    workoutViewModel.init(7);
    workoutViewModel.getWorkout().observe(this, w -> this.updateWorkoutsList(w, false));

    this.imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
  }

  @Override
  public View onCreateView(
      @NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_workouts_list, container, false);
    this.recyclerView = view.findViewById(R.id.workoutsList);
    //        this.recyclerView.setHasFixedSize(true);
    RecyclerView.LayoutManager recyclerViewLayoutManager = new LinearLayoutManager(getContext());
    this.recyclerView.setLayoutManager(recyclerViewLayoutManager);

    this.recycleViewAdapter = new WorkoutListRecycleViewAdapter(this);
    this.recyclerView.setAdapter(recycleViewAdapter);

    this.actionButton = view.findViewById(R.id.floating_action_add_workout);
    this.actionButton.setOnClickListener(this);

    this.addBoxView = new AddBoxView(Objects.requireNonNull(getContext()));
    FrameLayout.LayoutParams addBoxLayoutParams =
        new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.MATCH_PARENT,
            FrameLayout.LayoutParams.WRAP_CONTENT,
            Gravity.CENTER);

    this.addBoxView.setLayoutParams(addBoxLayoutParams);
    this.addBoxView.getButton().setOnClickListener(this);

    return view;
  }

  @Override
  public void onClick(View v) {
    switch (v.getId()) {
      case R.id.floating_action_add_workout:
        this.addBoxView((FrameLayout) v.getParent(), v);
        break;
      case R.id.overlay_layout:
        removeAddBoxView((FrameLayout) v);
        break;
      case R.id.button:
        this.addNewWorkout(this.addBoxView.getInputText());
        break;
    }
  }


//Irrelevant code removed.... 

  private void addBoxView(FrameLayout viewGroup, View v) {
    this.addBoxStatus = true;
    viewGroup.setClickable(true);
    viewGroup.setOnClickListener(this);
    viewGroup.setBackgroundColor(
        getResources().getColor(R.color.cardview_shadow_start_color, null));
    viewGroup.removeView(v);
    viewGroup.addView(this.addBoxView);
    this.addBoxView.requestInputFocus();
    this.imm.showSoftInput(this.addBoxView.getInput(), InputMethodManager.SHOW_IMPLICIT);
  }

  private void removeAddBoxView(FrameLayout viewGroup) {
    viewGroup.setClickable(false);
    this.imm.hideSoftInputFromWindow(this.addBoxView.getInput().getWindowToken(), 0);
    viewGroup.removeView(this.addBoxView);
    viewGroup.setBackgroundColor(getResources().getColor(R.color.cardview_shadow_end_color, null));
    viewGroup.addView(this.actionButton);
    this.addBoxStatus = false;
  }
}
