我如何听取最后解雇BottomSheetDialogFragment？我想在最终解雇时保存用户更改...

我试过以下:

方法1

如果通过向下滑动对话框解除对话(不在背面按压或外面触摸),则仅触发此操作

@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
    Dialog d = super.onCreateDialog(savedInstanceState);
    d.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {

            BottomSheetDialog d = (BottomSheetDialog) dialog;   
            FrameLayout bottomSheet = (FrameLayout) dialog.findViewById(android.support.design.R.id.design_bottom_sheet);

            BottomSheetBehavior behaviour = BottomSheetBehavior.from(bottomSheet);
            behaviour.setState(BottomSheetBehavior.STATE_EXPANDED);
            behaviour.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
                @Override
                public void onStateChanged(@NonNull View bottomSheet, int newState) {
                    if (newState == BottomSheetBehavior.STATE_HIDDEN)
                    {
                        // Bottom Sheet was dismissed by user! But this is only fired, if dialog is swiped down! Not if touch outside dismissed the …

我有一个BottomSheetView具有animateLayoutChanges="true".最初它显示很好.但如果将visibility视图(内部BottomSheetView)更改GONE为VISIBLE,则应用程序会混乱计算并BottomSheetView移动到屏幕顶部.我试过设置布局layout_gravity=bottom的根目录BottomSheetView.但没有成功.

BottomSheetView在改变任何视图的可见性之前,我有我的图像.(点击图片查看完整尺寸)

更改视图的可见性(GONE到VISIBLE或VISIBLE到GONE)后,我的BottomSheetView移动到顶部.(点击图片查看完整尺寸)

我猜,Android在计算视图width和测量时会搞乱height.有什么办法解决这个问题？

我也试图让我的BottomSheetView完全延伸至父视图匹配,但不知何故,即拍即height的BottomSheetView比手机屏幕和-TUN创建滚动问题更长.

预期的解决方案:

1> BottomSheetView即使visibility视图改变,也要防止改变其位置.

要么

2>使BottomSheetView匹配成为父级,以便在弄乱计算后看起来不会很糟糕.

我使用此解决方案和此库在onCreate()的活动中实现了Bottom Sheet功能

   sheet = new BottomSheet.Builder(this, R.style.BottomSheet_Dialog)
        .title("New")
        .grid() // <-- important part
        .sheet(R.menu.menu_bottom_sheet)
        .listener(new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // TODO
    }
}).build();

现在,我想显示底部工作表,点击按钮并以同样的方式想要隐藏底部工作表点击同一个按钮,如果已经可见

我已经实现了一个BottomSheet对话框,我希望当用户在偷看时(未完全展开状态)触摸底部外面时防止底片消失.

我已经设置dialog.setCanceledOnTouchOutside(false);了代码,但它似乎没有任何影响.

这是我的BottomSheetDialogFragment类:

public class ShoppingCartBottomSheetFragment extends BottomSheetDialogFragment  {

    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) {
        }
    };

    @Override
    public void setupDialog(Dialog dialog, int style) {
        super.setupDialog(dialog, style);

        View contentView = View.inflate(getContext(), R.layout.fragment_shopping_cart_bottom_sheet, null);

        dialog.setCanceledOnTouchOutside(false);

        dialog.setContentView(contentView);

        CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams();
        CoordinatorLayout.Behavior behavior = params.getBehavior();

        if( behavior != null && behavior …

BottomSheetDialog在应用程序之间切换时,背景闪烁.我究竟做错了什么 ？

MainActivity.java

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        findViewById(R.id.btn1).setOnClickListener(v -> {
            BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(MainActivity.this);
            bottomSheetDialog.setContentView(R.layout.content);
            bottomSheetDialog.show();
        });
    }
}

我正在使用Google Design Support Library 25.0.0在我的活动中,我有一个相对布局

app:layout_behavior="android.support.design.widget.BottomSheetBehavior"

现在当我引用它来添加BottomSheetBehaviour时,我收到错误

java.lang.IllegalArgumentException: The view is not associated with BottomSheetBehavior

这是布局:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/maps_colayout"
xmlns:app="http://schemas.android.com/tools"
android:fitsSystemWindows="true"
android:background="@color/white">

...

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="280dp"
    android:layout_gravity="bottom"
    android:id="@+id/rl_bottomsheet"
    android:background="#F3F3F3"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior">

    ...

</RelativeLayout>

这是活动相关代码:

CoordinatorLayout colayout = (CoordinatorLayout) findViewById(R.id.maps_colayout);
    View bottomSheet = colayout.findViewById(R.id.rl_bottomsheet);
    BottomSheetBehavior behavior = BottomSheetBehavior.from(bottomSheet);
    behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            // React to state change
        }

        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {
            // React to dragging …

如何BottomSheetDialog(Fragment)使用ToolBar 创建一个切换到全屏的模态,如材料设计规范中所示？

我可以通过添加a BottomSheetBehavior.BottomSheetCallback并根据slideOffset设置ToolBar的alpha来手动添加ToolBar.移动底板时,这有点像hacky但似乎有效.但是,当我的底部工作表包含EditText并显示键盘时,这不起作用.我尝试了两个版本:BottomSheetDialogFragment并手动将行为添加到新片段.

• 有没有更简单的方法来实现这一目标？
• 当显示键盘并且底部纸张占用整个空间时,我可以触发工具栏吗？

如何在新的 android jetpack compose 中创建圆角 BottomDrawer（又名 Modal Bottom Sheet）。

例如图像

我已经尝试了新BottomSheetBehaviour的设计库23.0.2,但我认为它太有限了.当我用setState()方法更改状态时,底部图片使用广告动画移动到新状态.

如何在没有动画的情况下立即更改状态？我没有看到公开的方法来做到这一点.

键盘下方还有更多字段.这发生在我更新支持库时.我知道它是Kotlin但它看起来几乎和java一样.我该如何解决这个问题？

这就是它的样子:

我的代码:

class ProjectsEditBottomSheetFragment(val privateID: String,
                                  val publicID: String) : BottomSheetDialogFragment() {



private val mBottomSheetBehaviorCallback = object : BottomSheetBehavior.BottomSheetCallback() {
    override fun onStateChanged(bottomSheet: View, newState: Int) {
        if (newState == BottomSheetBehavior.STATE_HIDDEN) {
            dismiss()
        }

    }


    override fun onSlide(bottomSheet: View, slideOffset: Float) {
        if (slideOffset < -0.15f) {
            dismiss()
        }
    }
}


override fun setupDialog(dialog: Dialog, style: Int) {
    super.setupDialog(dialog, style)
    val view = View.inflate(context, R.layout.projects_edit_sheet, null)
    dialog.setContentView(view)

    dialog.window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)


    val params = (view.parent as View).layoutParams as CoordinatorLayout.LayoutParams
    val behavior = …
