進階 Place Details 元件
Place Details 元件的進階版提供與地點詳細資料基本版相同的功能。您也可以設定元件的動作按鈕,並對顯示的評論和媒體套用搜尋和篩選選項。
內建 Jetpack Compose 支援
Places UI Kit 提供 AdvancedPlaceDetailsCompact 適用的 Jetpack Compose @Composable 函式。這些可組合函式使用提升的狀態、內建修飾符支援和 Compose 原生 Slot DSL。
以下程式碼範例示範如何將可組合函式用於直向版面配置。
Kotlin
import android.util.Log import androidx.compose.foundation.layout.fillMaxWidth import androidx.compose.foundation.layout.padding import androidx.compose.material3.MaterialTheme import androidx.compose.material3.Text import androidx.compose.runtime.Composable import androidx.compose.ui.Modifier import androidx.compose.ui.graphics.painter.Painter import androidx.compose.ui.unit.dp import com.google.android.libraries.places.api.model.Place import com.google.android.libraries.places.compose.AdvancedPlaceDetailsCompact import com.google.android.libraries.places.compose.PlaceReference import com.google.android.libraries.places.compose.action.CornerAction import com.google.android.libraries.places.compose.action.MainAction import com.google.android.libraries.places.compose.Orientation @Composable fun SampleAdvancedPlaceDetailsCompactCard( placeId: String, bookmarkIcon: Painter, onSavePlaceClicked: (Place) -> Unit ) { AdvancedPlaceDetailsCompact( // defines the place to be displayed reference = PlaceReference.PlaceId(placeId), // defines the orientation orientation = Orientation.VERTICAL, // defines custom styling modifier = Modifier .fillMaxWidth() .padding(16.dp), preferTruncation = true, enableLightbox = true, mainActions = { place -> listOf( MainAction.OpenDirections(), MainAction.OpenWebsite(), MainAction.Call() ) }, // action button configuration cornerActions = { place -> listOf( CornerAction.Custom( icon = bookmarkIcon, text = "Save Place", onClick = { onSavePlaceClicked(place) } ) ) }, onPlaceLoaded = { place -> Log.d("Places", "Successfully loaded place: ${place.id}") }, onPlaceLoadFailed = { exception -> Log.e("Places", "Failed to load place", exception) } ) { // --- Slot: Injected directly above the place name --- basicSectionTop { Text( text = "Featured in 'Top 10 Coffee Shops in SF'", style = MaterialTheme.typography.labelSmall, color = MaterialTheme.colorScheme.secondary, modifier = Modifier.padding(top = 4.dp, bottom = 2.dp) ) } // --- Slot: Injected directly below the action buttons --- basicSectionBottom { Text( text = "Notes: Great quiet atmosphere for meetings.", style = MaterialTheme.typography.bodySmall, color = MaterialTheme.colorScheme.onSurfaceVariant ) } } }
進階地點詳細資料設定
使用 AdvancedPlaceDetailsFragment 或 AdvancedPlaceDetailsCompactFragment 存取進階功能。
設定動作按鈕
使用 AdvancedPlaceDetailsFragment 或 AdvancedPlaceDetailsCompactFragment 的 PlaceActionProvider 介面定義及自訂動作按鈕。
如果您使用 @composable 函式,請使用 mainActions 和 cornerActions lambda 設定動作按鈕。
視覺出處註明規定
重要事項:如果自訂動作按鈕會將使用者資訊分享給 Google 以外的第三方,請務必清楚告知使用者。請參閱視覺化出處註明規定。
右側的範例顯示自訂圖片,清楚說明使用者資訊將傳送至「Altostrat」。
套用搜尋和篩選選項
使用 AdvancedPlaceDetailsFragment 或 AdvancedPlaceDetailsCompactFragment 的 SearchMediaOptions 和 SearchReviewsOptions 類別,啟用媒體或評論的搜尋和篩選功能。
如果您使用 @composable 函式,請使用 com.google.android.libraries.places.compose.search.SearchMediaOptions 啟用媒體或評論的搜尋和篩選功能。
建立自訂內容插槽
自訂內容插槽可讓您直接在預先定義的版面配置區域中,加入自己的內容 (例如 AI 生成摘要、行程時間戳記或自訂徽章)。
內容位置的出處註明規定和內容建議
掛接自訂內容位置時,揭露事項會自動更新,說明哪些內容由 Google 提供,哪些內容由第三方提供。
正確做法
在 Google 地點詳細資料和自訂內容之間維持清楚的視覺階層,避免資訊來源不明。
正確做法
請考慮提供符合使用者當下目標的在地化實用洞察資料。量身打造的內容 (例如即時預訂時間或目前供應情形) 有助於使用者更快做出更明智的決定。
錯誤做法
即使隱藏了 Google 提供的內容,也不要重複現有的 Google 地點詳細資料,例如評分、評論或營業時間。這麼做可能會讓使用者混淆內容來源,不確定內容是來自 Google 還是第三方。
錯誤做法
請勿顯示未標示出處的聲明或徽章 (例如「最佳推薦!」),以免誤導消費者以為是 Google 官方認可。自訂內容必須明確標示來源。
錯誤做法
請勿在自訂地點容器中加入廣告、行銷文案、促銷折扣或訂閱提示。
如要新增自訂內容,請使用 AdvancedPlaceDetailsCompact 可組合函式。使用 basicSectionTop 或 basicSectionBottom 指定內容位置。
進階地點詳細資料範例
自訂動作按鈕
使用 PlaceActionProvider 介面控制每個地點可用的動作。
Kotlin
class PlaceDetailsWidgetTestActivity : BaseActivity() { // simplified example of starting the fragment fun setupPPDFragment() { fullWidgetSelectedContent = AdvancedPlaceDetailsFragment.ALL_CONTENT.toMutableList() AdvancedPlaceDetailsFragment.newInstance(fullWidgetSelectedContent, Orientation.VERTICAL) supportFragmentManager .beginTransaction() .replace(R.id.fragment_container, fragment!!) .commitNow() } // you can set the callback elsewhere, but this is the ideal callback spot override fun onAttachFragment(fragment: Fragment) { super.onAttachFragment(fragment) when (fragment) { is PlaceActionController -> setPlaceActionProvider(fragment) } } // have this callback return an empty list to hide all buttons // if this callback isn't set, default buttons appear private fun setPlaceActionProvider(fragment: PlaceActionController) { fragment.setPlaceActionProvider( object : PlaceActionProvider { override fun getMainPlaceActions(place: Place): List<PlaceAction> = buildList { // predefined actions can be mixed in with custom ones add(PlaceAction.OPEN_IN_MAPS) // example of button with both text label and icon add( PlaceAction.builder() .setLabelTextResId(R.string.custom_action) .setIconResId(R.drawable.gs_custom_action_icon) .setContentDescriptionResId(R.string.custom_action_description) .setOnClickListener { /* todo perform action */ } .build() ) // icon only button add( PlaceAction.builder() .setIconResId(R.drawable.custom_action_icon_2) .setContentDescriptionResId(R.string.custom_action_description_2) .setOnClickListener { /* todo perform action */} .build() ) // text label only button add( PlaceAction.builder() .setLabelTextResId(R.string.custom_action_3) .setContentDescriptionResId(R.string.custom_action_description_2) .setOnClickListener {/* todo perform action */ } .build() ) } /** You can also specify whether corner buttons should appear. For either callback, returning an empty list results in no buttons appearing */ override fun getCornerPlaceActions(place: Place): List<PlaceAction> { return emptyList() } override fun addPlaceActionsChangedListener( listener: PlaceActionProvider.OnChangedListener ) { // in this example, just one listener and widget this@HostAppActivity.listener = listener } override fun removePlaceActionsChangedListener( listener: PlaceActionProvider.OnChangedListener ) { // if there are multiple listeners, remove only the provided listener this@HostAppActivity.listener = null } }) } }
新增自訂和預先定義的動作
這個範例會新增切換按鈕,供使用者將地點加入或移除我的最愛。
Kotlin
private var listener: PlaceActionProvider.OnChangedListener? = null private fun setPlaceActionProvider(fragment: PlaceActionController) { fragment.setPlaceActionProvider( object : PlaceActionProvider { private var placeFavorited = false override fun getMainPlaceActions(place: Place): List<PlaceAction> { val buttonList = mutableListOf<PlaceAction>() if (placeFavorited) { buttonList.add( PlaceAction.builder() .setLabelTextResId(R.string.place_details_button_config_favorite) .setIconResId(R.drawable.gs_web_vd_theme_24) .setOnClickListener { placeFavorited = !placeFavorited refreshButtonConfigs() } .build() ) } else { buttonList.add( PlaceAction.builder() .setLabelTextResId(R.string.place_details_button_config_unfavorite) .setIconResId(R.drawable.gs_web_vd_theme_24) .setOnClickListener { placeFavorited = !placeFavorited refreshButtonConfigs() } .build() ) } return buttonList } override fun addPlaceActionsChangedListener( listener: PlaceActionProvider.OnChangedListener ) { this@PlaceDetailsWidgetTestActivity.listener = listener } override fun removePlaceActionsChangedListener( listener: PlaceActionProvider.OnChangedListener ) { // if there are multiple listeners, remove only the provided listener this@PlaceDetailsWidgetTestActivity.listener = null } } ) } private fun refreshButtonConfigs() { listener?.onPlaceActionsChanged() }
使用預先定義的標準按鈕
建立執行 Google 定義標準動作的動作按鈕。
Kotlin
override fun getMainPlaceActions(place: Place): List<PlaceAction> { val buttonList = mutableListOf<PlaceAction>() // these buttons will have different background and text color than user-created buttons. // Text and icon button buttonList.add(PlaceAction.OPEN_IN_MAPS) // Icon-only buttons not enabled for main action buttons // Use of kotlin extension to do the same. see PlaceAction.OPEN_IN_MAPS { setIconResId(0) } return buttonList }
篩選評論和媒體
這個程式碼範例只會顯示提及「義大利麵」和「美味」的媒體和評論。
Kotlin
import com.google.android.libraries.places.widget.AdvancedPlaceDetailsFragment import com.google.android.libraries.places.widget.model.SearchMediaOptions import com.google.android.libraries.places.widget.model.SearchReviewsOptions import com.google.android.libraries.places.widget.model.Orientation import com.google.android.libraries.places.R // 1. Create options using the Java builders (called from Kotlin) val mediaOptions = SearchMediaOptions.builder() .setQuery("spaghetti") .setRankPreference(SearchMediaOptions.RankPreference.MOST_RELEVANT) .build() val reviewOptions = SearchReviewsOptions.builder() .setQuery("tasty") .setRankPreference(SearchReviewsOptions.RankPreference.NEWEST) .build() // 2. Create the fragment val fragment = AdvancedPlaceDetailsFragment.newInstance( AdvancedPlaceDetailsFragment.STANDARD_CONTENT, Orientation.VERTICAL, R.style.PlacesMaterialTheme ) // 3. Apply options to the fragment fragment.applySearchMediaOptions(mediaOptions) fragment.applySearchReviewsOptions(reviewOptions)
