我正在使用a DialogFragment,虽然我已成功设置图像以在关闭时关闭(即关闭)对话框,但当用户点击对话框外的任何地方时,我很难找到解除对话框的方法,就像它一样正常的对话.我以为会有某种

dialogFragment.setCanceledOnTouchOutside(true);

打电话,但我没有在文档中看到.

这有可能DialogFragment吗？或者我在错误的地方寻找？我尝试拦截"父母"活动中的触摸事件,但除了没有得到任何触摸事件外,它对我来说似乎不对.

我如何听取最后解雇BottomSheetDialogFragment？我想在最终解雇时保存用户更改...

我试过以下:

方法1

如果通过向下滑动对话框解除对话(不在背面按压或外面触摸),则仅触发此操作

@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
    Dialog d = super.onCreateDialog(savedInstanceState);
    d.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {

            BottomSheetDialog d = (BottomSheetDialog) dialog;   
            FrameLayout bottomSheet = (FrameLayout) dialog.findViewById(android.support.design.R.id.design_bottom_sheet);

            BottomSheetBehavior behaviour = BottomSheetBehavior.from(bottomSheet);
            behaviour.setState(BottomSheetBehavior.STATE_EXPANDED);
            behaviour.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
                @Override
                public void onStateChanged(@NonNull View bottomSheet, int newState) {
                    if (newState == BottomSheetBehavior.STATE_HIDDEN)
                    {
                        // Bottom Sheet was dismissed by user! But this is only fired, if dialog is swiped down! Not if touch outside dismissed the …

我在我的活动中使用BottomSheetDialogFragment,对话框在纵向模式下显示全高,但在切换到横向模式时不显示.

MainActivity.java

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        CustomBottomSheetDialog customBottomSheetDialog = new CustomBottomSheetDialog();
        customBottomSheetDialog.show(getSupportFragmentManager(),customBottomSheetDialog.getTag());
    }
}

CustomBottomSheetDialog

public class CustomBottomSheetDialog extends BottomSheetDialogFragment {

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return View.inflate(getContext(), R.layout.view_config, null);
    }
}

CustomBottomSheetDialog布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:background="#fdf107"
              android:layout_height="wrap_content">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="196dp"
        android:gravity="center"
        android:textColor="@color/colorAccent"
        android:text="BottomSheetDialogFragment"/>

</LinearLayout>

在横向模式下,我必须拖动BottomSheetDialogFragment才能看到整个内容.
