如何使 BottomSheetDialog 匹配父高度（全屏）

Question

这是我使用的布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/layout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="top|center_horizontal"
android:background="@color/white"
android:gravity="top|center_horizontal"
android:orientation="vertical">

    <TextView
        android:id="@+id/provisioningTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Phone Number" />

</LinearLayout>

这是我创建对话框的类：

open class DialogProvisioningData : BottomSheetDialog {
constructor(context: Context) : super(context)


private lateinit var mBehavior: BottomSheetBehavior<FrameLayout>

override fun setContentView(view: View) {
    super.setContentView(view)
    val bottomSheet = window.decorView.findViewById<View>(R.id.design_bottom_sheet) as FrameLayout
    mBehavior = BottomSheetBehavior.from(bottomSheet)
    mBehavior.peekHeight = Resources.getSystem().getDisplayMetrics().heightPixels
    mBehavior.state = BottomSheetBehavior.STATE_EXPANDED
}

override fun onStart() {
    super.onStart()
    mBehavior.peekHeight = Resources.getSystem().getDisplayMetrics().heightPixels
    mBehavior.state = BottomSheetBehavior.STATE_EXPANDED
}

companion object {
    fun newInstance(context: Context): DialogProvisioningData {
        val dialog = DialogProvisioningData(context)
        var layoutInflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater;
        val bottomSheet = layoutInflater.inflate(R.layout.dialog_provisioning, null)
        bottomSheet.layout.setOnClickListener({ dialog.cancel() })
        dialog.setOnShowListener { dialog ->
            val d = dialog as BottomSheetDialog

            val bottomSheet = d.findViewById<View>(R.id.design_bottom_sheet) as FrameLayout?
            BottomSheetBehavior.from(bottomSheet!!).state = BottomSheetBehavior.STATE_EXPANDED
        }
        dialog.setContentView(bottomSheet)
        dialog.show()
        return dialog
    }
}
}

要让 BottomSheetDialog 真正全屏显示，我需要进行哪些更改？我已将状态设置为展开，并将 peekHeight 设置为屏幕高度

Answer 1

不要使用全屏 BottomSheet。 您可以从 DialogFragment 使用

用于显示对话框：

  FragmentManager fragmentManager = getSupportFragmentManager();
    DialogFullscreenFragment newFragment = new DialogFullscreenFragment();
    FragmentTransaction transaction = fragmentManager.beginTransaction();
    transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
    transaction.add(android.R.id.content, newFragment).addToBackStack(null).commit();

DialogFullscreenFragment 类：

public class DialogFullscreenFragment extends DialogFragment {


private View root_view;
private Slider slider;


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    root_view = inflater.inflate(R.layout.dialog_event, container, false);


    return root_view;
}


@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    return dialog;
}

}

我们可以通过像这样设置我们的view.minHeight 来解决它：

class SortProductBottomSheet : BaseBottomSheet() {

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View = inflater.inflate(R.layout.dialog_blablabla, container, false)-

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        //THIS IS OUR LIFESAVER
        val dm = Resources.getSystem().displayMetrics
        val rect = dm.run { Rect(0, 0, heightPixels, widthPixels) }
        view.minimumHeight = rect.height()
    }

}

在尝试了多种实现之后，这是我最满意的。它是全屏的，它是一个对话框，并且它还具有我需要的正确 SlideUpAnimation。此外，从片段内部调用 if 很容易，而无需关闭我自己的片段：

open class DialogProvisioningData : Dialog {
constructor(context: FragmentActivity, themeResId: Int) : super(context, themeResId)

    companion object {
        val TAG: String = "DialogProvisioningData"

        fun newInstance(context: FragmentActivity): DialogProvisioningData {
            val dialog = DialogProvisioningData(context, R.style.DialogAnimation)
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
            dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation
            var layoutInflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
            val bottomSheet = layoutInflater.inflate(R.layout.dialog_provisioning, null)

            dialog.setContentView(bottomSheet)
            dialog.show()
            return dialog
        }
    }
}
