BottomSheetDialogFragment打开一半

Question

BottomSheetDialogFragment当我打开它时,我打开一半(意思是不完全).

fragment.show(supportFragmentManager, "my_frag")

• 我尝试NestedScrollView过behavior_peekHeight但没有奏效.
• 没有尝试NestedScrollView.只有LinearLayout.
• 在match_parent&之间尝试切换高度wrap_content

我有简单RecyclerView的BottomSheetDialogFragment布局.

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <LinearLayout
            ...
            >
           <android.support.v7.widget.RecyclerView
           ...
           />

通过BottomSheetFragment你的意思BottomSheetDialogFragment.要打开已消耗的工作表,您需要进行一些更改onCreateDialog().

 @Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    BottomSheetDialog bottomSheetDialog=(BottomSheetDialog)super.onCreateDialog(savedInstanceState);
    bottomSheetDialog.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            BottomSheetDialog dialog = (BottomSheetDialog) dialog;
            FrameLayout bottomSheet =  dialog .findViewById(android.support.design.R.id.design_bottom_sheet);
            BottomSheetBehavior.from(bottomSheet).setState(BottomSheetBehavior.STATE_EXPANDED);
            BottomSheetBehavior.from(bottomSheet).setSkipCollapsed(true);
            BottomSheetBehavior.from(bottomSheet).setHideable(true);
        }
    });
    return bottomSheetDialog;
}

只需保持布局match_parent无需使用NestedScrollView.它对我有用.如果您仍然遇到问题,请告诉我.

如果有人使用新材料库.这是
implementation 'com.google.android.material:material:1.0.0'.然后你需要更改Parent的id FrameLayout.所以它会.

 @Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    BottomSheetDialog bottomSheetDialog=(BottomSheetDialog)super.onCreateDialog(savedInstanceState);
    bottomSheetDialog.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dia) {
            BottomSheetDialog dialog = (BottomSheetDialog) dia;
            FrameLayout bottomSheet =  dialog .findViewById(com.google.android.material.R.id.design_bottom_sheet);
            BottomSheetBehavior.from(bottomSheet).setState(BottomSheetBehavior.STATE_EXPANDED);
            BottomSheetBehavior.from(bottomSheet).setSkipCollapsed(true);
            BottomSheetBehavior.from(bottomSheet).setHideable(true);
        }
    });
    return bottomSheetDialog;
}

import com.google.android.material在这种情况下,请确保所有导入.
