Android Fullscreen Fragment对话框错误

Question

我创建了一个"全屏"DialogFragment,其中我添加了一个透明黑色背景.最终结果可以在下面的截图中看到:

这是我如何做到的:

@Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        return dialog;
    }



    @Override
    public void onStart() {
        super.onStart();
        Dialog dialog = getDialog();
        if (dialog != null) {
            dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            // if >= LOLLIPOP, then I color the the statusbar
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            dialog.getWindow().setStatusBarColor(SOME_COLOR_HERE);
        }

    }

@Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(DialogFragment.STYLE_NO_TITLE, R.style.DialogFullScreen);
    }

这是我在setStyle()上设置的主题:

<style name="DialogFullScreen">
    <item name="android:windowIsFloating">false</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

这是我为片段扩充的布局:

这些截图来自运行Android 5.1的Xperia Z3.这在许多设备上运行良好,甚至在一些低端的三星4.2设备上也经过测试.问题是它不适用于Nexus 4,也适用于Android 5.1.在Nexus 4上,似乎透明度不起作用,并且视图在后台被多次复制.这是一个截图:

这是Xperia Z3和Nexus 4之间的另一个比较:

Nexus 4上发生了什么？任何帮助表示赞赏!

然后为对话框创建自定义布局，在 onCreate 或对话框方法的第一个方法中使用下面的代码。

Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.your_dialog_layout);
        dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

它对我有用。我使用了一种方法来创建全屏对话框。
