高级地点详情组件

高级版地点详情组件提供的功能与 Essentials 版地点详情组件 相同。此外，您还可以配置该组件的操作按钮，并对显示的评价和媒体内容应用搜索和过滤选项。

内置 Jetpack Compose 支持

Places UI Kit 为 AdvancedPlaceDetailsCompact 提供了 Jetpack Compose @Composable 函数。这些可组合项使用提升的状态、内置修饰符支持和 Compose 原生槽 DSL。

以下代码示例演示了如何将可组合函数用于垂直布局。

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
            )
        }
    }
}

高级地点详情配置

使用 AdvancedPlaceDetailsFragment 或 AdvancedPlaceDetailsCompactFragment 访问高级功能。

配置操作按钮

使用 AdvancedPlaceDetailsFragment 或 AdvancedPlaceDetailsCompactFragment 的 PlaceActionProvider 接口来定义和自定义操作按钮。

如果您使用的是 @composable 函数，请使用 mainActions 和 cornerActions lambda 来配置操作按钮。

视觉效果提供方说明要求

包含自定义按钮的地点详情紧凑视图
高级地点详情紧凑视图，其中包含自定义按钮

重要提示： 您必须向最终用户明确说明，自定义操作按钮何时会与 Google 以外的第三方分享用户信息。请参阅视觉效果标明出处要求。

右侧的示例显示了一个自定义图片，该图片明确说明用户信息将发送给“Altostrat”。

应用搜索和过滤选项

使用 AdvancedPlaceDetailsFragment 或 AdvancedPlaceDetailsCompactFragment 的 SearchMediaOptions 和 SearchReviewsOptions 类，为媒体内容或评价启用搜索和过滤功能。

如果您使用的是 @composable 函数，请使用 com.google.android.libraries.places.compose.search.SearchMediaOptions 为媒体内容或评价启用搜索和过滤功能。

创建自定义内容槽

自定义内容广告位展示位置选项

借助自定义内容槽，您可以将自己的内容（例如 AI 生成的摘要、行程时间戳或自定义徽章）直接添加到预定义的布局区域中。

内容槽的提供方说明要求和内容建议

装载自定义内容槽后，披露信息会自动更新，以明确说明哪些内容由 Google 提供，以及哪些内容由第三方提供。

请

在 Google 地点详情和自定义内容之间保持清晰的视觉层次结构，以避免信息来源出现任何歧义。

避免信息来源不明确

请

考虑根据用户的即时目标量身定制本地化的高价值洞见。量身定制的内容（例如实时预订窗口或当前可用性）有助于用户更快地做出更明智的决策。

提供高价值的数据洞见

请勿

请勿重复使用现有的 Google 地点详情（例如评分、评价或营业时间），即使您已隐藏 Google 提供的内容也是如此。这样做可能会让用户对内容的来源感到困惑，不知道内容是来自 Google 还是第三方。

请勿复制现有 Google 地点详情

请勿

请勿显示未经说明的声明或徽章（例如“热门推荐！”），以免被误认为是 Google 的官方认可。自定义内容必须明确说明其来源。

请勿展示未注明出处的声明或徽章

请勿

请勿在自定义地点容器中添加广告、营销文案、促销折扣或订阅提示。

不得包含广告、营销文案、促销折扣或订阅提示

如需添加自定义内容，请使用 AdvancedPlaceDetailsCompact 可组合项。使用 basicSectionTop 或 basicSectionBottom 指定内容的位置。

高级地点详情示例

自定义操作按钮

使用 PlaceActionProvider 接口控制每个地点可用的操作。

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
        }
      })
  }
}

添加自定义操作和预定义操作

此示例添加了一个切换按钮，供用户收藏或取消收藏地点。

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()
}

使用预定义的标准按钮

创建执行 Google 定义的标准操作的操作按钮。

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
  }

过滤评价和媒体内容

此代码示例仅显示提及“spaghetti”和“tasty”的媒体内容和评价。

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)

创建内容槽

Kotlin

import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.Text
import androidx.compose.runtime.Composable
import com.google.android.libraries.places.compose.AdvancedPlaceDetailsCompact
import com.google.android.libraries.places.compose.PlaceReference

@Composable
fun ItineraryPlaceCard(placeId: String) {
    AdvancedPlaceDetailsCompact(
        reference = PlaceReference.PlaceId(placeId)
    ) {
        // Slot: Injected directly above the place name
        basicSectionTop {
            Text(
                text = "Day 2 • 2:30 PM",
                style = MaterialTheme.typography.labelSmall,
                color = MaterialTheme.colorScheme.primary
            )
        }
        
        // Slot: Injected directly below the main action buttons
        basicSectionBottom {
            NotesCard(
                notes = "Great quiet atmosphere for morning meetings. Famous for house-roasted pour-overs."
            )
        }
    }
}
