Android 全屏对话框 fragment ，如日历应用程序

Question

我正在尝试实现如下图所示的全屏对话框。我能够显示全屏对话框，但是当显示对话框时，状态栏颜色变为黑色并且不保持原色深色。

这是我的对话 fragment

public class IconsDialogFragment extends DialogFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
        // Inflate the layout to use as dialog or embedded fragment
        return inflater.inflate(R.layout.fragment_icons_dialog, container, false);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        final RelativeLayout root = new RelativeLayout(getActivity());
        root.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

        // creating the fullscreen dialog
        final Dialog dialog = new Dialog(getActivity());
        dialog.setContentView(root);
        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.YELLOW));
        dialog.getWindow().setWindowAnimations(R.style.DialogAnimation);
        dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

        return dialog;
    }

}

全屏获取DialogFragment

像这样覆盖 DialogFragment 的 onStart:

@Override
public void onStart()
{
    super.onStart();
    Dialog dialog = getDialog();
    if (dialog != null)
    {
        int width = ViewGroup.LayoutParams.MATCH_PARENT;
        int height = ViewGroup.LayoutParams.MATCH_PARENT;
        dialog.getWindow().setLayout(width, height);
    }
}

为了设置 StatusBarColor，您需要设置标志:FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS

public void setStatusBarColorIfPossible(int color) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
   getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
   getWindow().setStatusBarColor(color);
   }
}
