如何使 BottomSheetDialog 匹配父高度(全屏)
How can I make BottomSheetDialog match parent height (full screen)
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 class:
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
}
}
}
我需要更改什么才能使 BottomSheetDialog 真正全屏显示?我已将状态设置为展开,并将 peekHeight 设置为屏幕高度
不要使用全屏 BottomSheet。
你可以使用 DialogFragment
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 class:
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;
}
}
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,它还有我需要的正确的 SlideUpAnimation。此外,从片段内部调用 if 也很容易,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
}
}
}
我们可以通过这样设置我们的 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()
}
}
