Question

我的Android应用程序中具有以下layout.xml。我想将按钮移到屏幕底部。就在我的广告之上。但它将保持在列表视图的正下方。我该如何实现？我尝试过layout_gravity =“ bottom | right”，也尝试过layout_alignParentBottom =“ true”都没有将按钮放在我想要的位置。任何帮助表示赞赏

您按钮的父级布局为/** * @param DomainObjectInterface $object * @param $targetLanguageUid * @return DomainObjectInterface|null */ public function translate($object, $targetLanguageUid) { /** @var AbstractDomainObject $objectCopy */ $objectCopy = new $this->objectType; $properties = ObjectAccess::getGettableProperties($object); foreach ($properties as $propertyName => $propertyValue) { ObjectAccess::setProperty($objectCopy, $propertyName, $propertyValue); } $objectCopy->_setProperty('_localizedUid', $object->getUid()); $objectCopy->_setProperty('_languageUid', $targetLanguageUid); $objectCopy->_setProperty('_versionedUid', $object->getUid()); return $objectCopy; }

LinearLayout适用于layout_gravity="bottom|right"

FrameLayout适用于layout_alignParentBottom="true"

但是您必须使用适当的布局更改父布局。

如何在布局文件中将按钮按下到屏幕底部？
