So gelang es mir schließlich, dieses Problem zu lösen, indem sie direkt suchen in die BottomSheetDialog Implementierung, und ich entdeckte, dass es nichts anderes als eine einfache Dialog in einem regulärengewickelt war 210.
Das Problem war in den BottomSheetCallBack:
@Override
public void onStateChanged(@NonNull View bottomSheet,
@BottomSheetBehavior.State int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
dismiss();
}
}
Das Problem tritt auf, wenn der Zustand HIDDEN erreicht wird, das geschieht, wenn der Dialog, indem sie nach unten gezogen wird zurückgewiesen. Danach bleibt der Dialog verborgen, auch wenn bottomSheetDialog.show() aufgerufen wird. Die einfachste Lösung, die ich gefunden habe, war, diesen Zustand zu entfernen und ihn durch den Zustand COLLAPSED zu ersetzen.
ich erstellen classCustomBottomSheetDialog, kopiert die gesamte BottomSheetDialog Klasse und hat eine einzige Zeile das Problem zu beheben:
@Override
public void onStateChanged(@NonNull View bottomSheet,
@BottomSheetBehavior.State int newState) {
if (newState == CustomBottomSheetBehavior.STATE_HIDDEN) {
dismiss();
bottomSheetBehavior.setState(CustomBottomSheetBehavior.STATE_COLLAPSED);
}
}
Hier ist der endgültige Code:
public class CustomBottomSheetDialog extends AppCompatDialog {
public CustomBottomSheetDialog (@NonNull Context context) {
this(context, 0);
}
public CustomBottomSheetDialog (@NonNull Context context, @StyleRes int theme) {
super(context, getThemeResId(context, theme));
// We hide the title bar for any style configuration. Otherwise, there will be a gap
// above the bottom sheet when it is expanded.
supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
}
protected CustomBottomSheetDialog (@NonNull Context context, boolean cancelable,
OnCancelListener cancelListener) {
super(context, cancelable, cancelListener);
supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
}
@Override
public void setContentView(@LayoutRes int layoutResId) {
super.setContentView(wrapInBottomSheet(layoutResId, null, null));
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setLayout(
ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
}
@Override
public void setContentView(View view) {
super.setContentView(wrapInBottomSheet(0, view, null));
}
@Override
public void setContentView(View view, ViewGroup.LayoutParams params) {
super.setContentView(wrapInBottomSheet(0, view, params));
}
private View wrapInBottomSheet(int layoutResId, View view, ViewGroup.LayoutParams params) {
final CoordinatorLayout coordinator = (CoordinatorLayout) View.inflate(getContext(),
R.layout.design_bottom_sheet_dialog, null);
if (layoutResId != 0 && view == null) {
view = getLayoutInflater().inflate(layoutResId, coordinator, false);
}
FrameLayout bottomSheet = (FrameLayout) coordinator.findViewById(R.id.design_bottom_sheet);
BottomSheetBehavior.from(bottomSheet).setBottomSheetCallback(mBottomSheetCallback);
if (params == null) {
bottomSheet.addView(view);
} else {
bottomSheet.addView(view, params);
}
// We treat the CoordinatorLayout as outside the dialog though it is technically inside
if (shouldWindowCloseOnTouchOutside()) {
coordinator.findViewById(R.id.touch_outside).setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View view) {
if (isShowing()) {
cancel();
}
}
});
}
return coordinator;
}
private boolean shouldWindowCloseOnTouchOutside() {
if (Build.VERSION.SDK_INT < 11) {
return true;
}
TypedValue value = new TypedValue();
//noinspection SimplifiableIfStatement
if (getContext().getTheme()
.resolveAttribute(android.R.attr.windowCloseOnTouchOutside, value, true)) {
return value.data != 0;
}
return false;
}
private static int getThemeResId(Context context, int themeId) {
if (themeId == 0) {
// If the provided theme is 0, then retrieve the dialogTheme from our theme
TypedValue outValue = new TypedValue();
if (context.getTheme().resolveAttribute(
R.attr.bottomSheetDialogTheme, outValue, true)) {
themeId = outValue.resourceId;
} else {
// bottomSheetDialogTheme is not provided; we default to our light theme
themeId = R.style.Theme_Design_Light_BottomSheetDialog;
}
}
return themeId;
}
private BottomSheetBehavior.BottomSheetCallback mBottomSheetCallback
= new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet,
@BottomSheetBehavior.State int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
dismiss();
bottomSheetBehavior.setState(CustomBottomSheetBehavior.STATE_COLLAPSED);
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
}
};
}
Daumen hoch für diese Lösung danke: D –
Ich konnte diesen Code nicht kopieren und einfügen, weil es keinen Bezug zu BottomSheetBehavior gibt, wenn Sie den Status festlegen. –
