Я попробовал новый BottomSheet
в поддержку Android. Внутри BottomSheet
я поместил TextView
и ScrollView
. BottomSheet
показывает очень хорошо, единственная проблема, которую я обнаружил, заключается в том, что ScrollView
в BottomSheet
не прокручивается. Каждый раз, когда я пытаюсь прокрутить, либо BottomSheet
макет в основном BottomSheet
изменяем состояние BottomSheet
от свертывания до BottomSheet
.
Это фрагмент моего кода класса активности:
private BottomSheetBehavior behavior;
View bottomSheet;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setTextViewOnClickListener(this, findViewById(R.id.parentLayout));
CoordinatorLayout coordinatorLayout = (CoordinatorLayout) findViewById(R.id.main_content);
// The View with the BottomSheetBehavior
bottomSheet = coordinatorLayout.findViewById(R.id.bottom_sheet);
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 events
}
});
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.tv1:
setTextViewHeader("Header1");
setTextViewContent("Long_Text_1");
break;
case R.id.tv2:
setTextViewHeader("Header2");
setTextViewContent("Long_Text_2");
break;
case R.id.tv3:
setTextViewHeader("Header3");
setTextViewContent("Long_Text_3");
break;
default:
break;
}
behavior.setPeekHeight(100);
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
behavior.setHideable(true);
bottomSheet.requestLayout();
}
