BottomSheet与EditText

我有自定义BottomSheetDialogFragment。这个片段有EditText和Button。BottomSheet与EditText

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:paddingLeft="24dp" 
    android:paddingRight="24dp" 
    android:paddingBottom="15dp" 
    android:focusableInTouchMode="true"> 

    <ImageView 
     android:layout_marginTop="10dp" 
     android:id="@+id/letter" 
     android:layout_height="50dp" 
     android:src="@drawable/key" 
     android:layout_width="60dp" 
     android:layout_gravity="center_horizontal"/> 

    <TextView 
     android:id="@+id/twPassInfo" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:textColor="@color/black" 
     android:paddingTop="10dp" 
     android:gravity="center" 
     android:text="We just need your registred Email or Phone number to send you password reset instructions" 
     /> 

    <EditText 
     android:id="@+id/etEmailPhone" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:background="@drawable/border_btn" 
     android:layout_marginTop="10dp" 
     android:hint="Input your e-mail or phone number" 
     android:inputType="text" 
     android:maxLength="30" 
     android:padding="10dp" 
     android:textColor="#0c8383" 
     android:textColorHint="#bbbbbb" 
     android:textSize="17sp"/> 

    <Button 
     android:id="@+id/bnRestorePass" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center_horizontal" 
     android:layout_marginTop="10dp" 
     android:background="@drawable/border_blue_btn" 
     android:text="Restore password" 
     android:textColor="@color/white" 
     android:textAllCaps="false" 
     android:textSize="17sp" /> 
</LinearLayout>

当我关闭键盘时，该片段几乎隐藏（请参阅屏幕截图）。 screen before opening keyboard screen after turning down keyboard

public class PasswordRestoringDialogFragment extends BottomSheetDialogFragment { 

    @BindView(R.id.twPassInfo) 
    TextView passInfo; 

    @BindView(R.id.bnRestorePass) 
    Button restorePass; 

    @BindView(R.id.etEmailPhone) 
    EditText emailPhone; 

    @Override 
    public void onCreate(@Nullable Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
    } 

    @Nullable 
    @Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.pass_restore_modal, container, false); 
     ButterKnife.bind(this, view); 

     Typeface typeface1 = Typeface.createFromAsset(SignInActivity.getInstance().getAssets(), "SourceSansPro-Regular.ttf"); 
     emailPhone.setTypeface(typeface1); 
     passInfo.setTypeface(typeface1); 


     Typeface typeface2 = Typeface.createFromAsset(SignInActivity.getInstance().getAssets(), "SourceSansPro-Bold.ttf"); 
     restorePass.setTypeface(typeface2); 

     return view; 
    } 

    private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback() { 
     @Override 
     public void onStateChanged(@NonNull View bottomSheet, int newState) { 
      if (newState == BottomSheetBehavior.STATE_HIDDEN) { 
       dismiss(); 
      } 
     } 

     @Override 
     public void onSlide(@NonNull View bottomSheet, float slideOffset) { 
     } 
    }; 

    @NonNull 
    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) { 
     Dialog dialog = super.onCreateDialog(savedInstanceState); 
     dialog.setOnShowListener(new DialogInterface.OnShowListener() { 
      @Override 
      public void onShow(DialogInterface dialog) { 
       BottomSheetDialog bottomSheetDialog = (BottomSheetDialog) dialog; 
       FrameLayout bottomSheet = (FrameLayout) ((BottomSheetDialog) dialog).findViewById(android.support.design.R.id.design_bottom_sheet); 
       BottomSheetBehavior.from(bottomSheet).setState(BottomSheetBehavior.STATE_EXPANDED); 
      } 
     }); 

     return dialog; 
    } 

    @Override 
    public void setupDialog(Dialog dialog, int style) { 
     super.setupDialog(dialog, style); 
     View contentView = View.inflate(getContext(), R.layout.pass_restore_modal, null); 
     dialog.setContentView(contentView); 
     CoordinatorLayout.LayoutParams layoutParams = 
       (CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams(); 
     CoordinatorLayout.Behavior behavior = layoutParams.getBehavior(); 
     if (behavior != null && behavior instanceof BottomSheetBehavior) { 
      ((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback); 
     } 

    } 
}

我重写onCreateDialog(Bundle savedInstanceState)方法：

@NonNull 
@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 
    Dialog dialog = super.onCreateDialog(savedInstanceState); 
    dialog.setOnShowListener(new DialogInterface.OnShowListener() { 
     @Override 
     public void onShow(DialogInterface dialog) { 
      BottomSheetDialog bottomSheetDialog = (BottomSheetDialog) dialog; 
      final FrameLayout bottomSheet = (FrameLayout) ((BottomSheetDialog) dialog).findViewById(android.support.design.R.id.design_bottom_sheet); 
      final BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(bottomSheet); 
      bottomSheetBehavior.setBottomSheetCallback(mBottomSheetBehaviorCallback); 
      bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED); 
      bottomSheetBehavior.setPeekHeight(500); 
      KeyboardVisibilityEvent.setEventListener(SignInActivity.getInstance(), new KeyboardVisibilityEventListener() { 
       @Override 
       public void onVisibilityChanged(boolean isOpen) { 
        if (!isOpen) { 
         bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED); 
        } 
       } 
      }); 
     } 
    }); 


    return dialog; 
}

现在有什么？

像这样

<LinearLayout 
    android:id="@+id/bottom_sheet" 
    android:minHeight="120dp" 
    app:behavior_peekHeight="220dp" 
    ... 
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior"> 
    ... 
</LinearLayout>

父布局使用底部片状物行为和PEEK height属性：

forgotPass.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      BottomSheetDialogFragment passwordResetDialogFragmnet = new PasswordRestoringDialogFragment(); 
      passwordResetDialogFragmnet.show(getSupportFragmentManager(), passwordResetDialogFragmnet.getTag()); 
     } 
    });

活性的XML

如果没有解决问题，则在键盘打开/关闭时通过代码设置窥视高度。
