片段对话框中的沉浸式模式

Question

如何在显示片段对话框时保持沉浸式模式。我已经创建了一个继承自对话框片段但不工作的类。

Answer 1

在对话框或BottomSheetDialogFragment中，你必须实现这个解决方案，这是我的工作。

步骤1：

在对话框或BottomSheetDialog中，用onActivityCreated方法编写以下代码，

override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
var viewParent = view
while (viewParent is View) {
    viewParent.fitsSystemWindows = false
    viewParent.setOnApplyWindowInsetsListener { _, insets -> insets }
    viewParent = viewParent.parent as View?
 }
}

步骤2:另外，覆盖下面的方法：

override fun setupDialog(dialog: Dialog, style: Int) {

 super.setupDialog(dialog, style)
    dialog?.window?.setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, 
 WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE)

}

现在看看它的魔力:)

Answer 2

在onCreateDialog上覆盖。

@Override
public Dialog onCreateDialog(final Bundle savedInstanceState) {

    final Dialog dialog = new Dialog(getActivity());
    dialog.setCanceledOnTouchOutside(false);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    dialog.getWindow().getDecorView().setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
    dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    dialog.setContentView(root);
    dialog.getWindow().setLayout(500, 500);

    return dialog;
}

我做了固定尺寸的。请参阅http://vardhan-justlikethat.blogspot.com/2014/06/android-immersive-mode-for-dialog.html中的这篇文章
