我正在使用 PopupWindow 来显示验证错误和 showAsDropDown(anchor).Validation 字段是通过按下保存按钮来验证的，所以如果锚点放置在操作栏下，它的弹出窗口会与 actionBar 重叠。我该如何解决？

 protected void showPopup(View anchorPlace) {
    popupContainer.removeAllViews();
    popupContainer.addView(recyclerErrors);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        popupContainer.setElevation(0);
        anchorPlace.setElevation(0);
        popup.setElevation(0);
    }
    recyclerErrors.setOnClickListener(v -> dismissPopup());
    popup.setContentView(popupContainer);
    if (anchorPlace != null) {
        popup.setWidth(anchorPlace.getWidth());
    }
    popup.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
    popup.setOutsideTouchable(true);
    popup.setFocusable(false);
    popup.setTouchable(true);
    popup.setBackgroundDrawable(null);

    if (anchorPlace != null) {
        PopupWindowCompat.showAsDropDown(popup, anchorPlace, 0, 0, Gravity.BOTTOM);
    }

    if (popup.isAboveAnchor()) {
        popup.dismiss();
    }
}

验证错误 XML 的弹出窗口：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="20dp"
    app:srcCompat="@drawable/warning_triangle" />
