java - PopupWindow 与 ActionBar 重叠

Question

我使用 PopupWindow 通过 showAsDropDown(anchor) 显示验证错误。验证字段通过按保存按钮进行验证，因此如果 anchor 位于操作栏下方，则其弹出窗口会与操作栏重叠。我该如何解决这个问题？

 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();
    }
}

弹出验证错误 XML:

<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" />

<TextView
    android:id="@+id/error_field_error_txt"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/warning_bcg"

    android:paddingTop="@dimen/settings_error_body_padding_top_bottom"
    android:paddingEnd="@dimen/settings_error_body_padding_start_end"
    android:paddingBottom="@dimen/settings_error_body_padding_top_bottom"
    android:textColor="@android:color/white"
    android:textSize="@dimen/settings_error_text_size"
    android:textStyle="bold"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"/></LinearLayout>

Answer 1

尝试popup.setAttachedInDecor(true)

This will attach the popup window to the decor frame of the parent window to avoid overlaping with screen decorations like the navigation bar.

您也可以尝试使用popup.setOverlapAnchor(false)

Sets whether the popup window should overlap its anchor view when displayed as a drop-down.

希望有帮助。
