進階 Place Details 元件

這是 Pro 元件，收費方式與 Essentials 元件不同。詳情請參閱總覽。

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。

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。

圖片出處資訊相關規定

進階地點詳細資料精簡檢視畫面，附有自訂按鈕

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，您必須向使用者明確說明。請參閱視覺化出處資訊規定。

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 介面，啟用媒體或評論的搜尋和篩選功能。

進階地點詳細資料範例

自訂動作按鈕

使用 PlaceActionProvider 介面控管每個地點可執行的動作。

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
          [e-mail] = listener
        }

        override fun removePlaceActionsChangedListener(
          listener: PlaceActionProvider.OnChangedListener
        ) {
          // if there are multiple listeners, remove only the provided listener
          [e-mail] = null
        }
      })
  }
}

新增自訂和預先定義的動作

這個範例會新增切換按鈕，供使用者收藏或取消收藏地點。

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
        ) {
          [e-mail] = listener
        }

        override fun removePlaceActionsChangedListener(
          listener: PlaceActionProvider.OnChangedListener
        ) {
          // if there are multiple listeners, remove only the provided listener
          [e-mail] = null
        }
      }
    )
  }

private fun refreshButtonConfigs() {
    listener?.onPlaceActionsChanged()
}

使用預先定義的標準按鈕

建立可執行 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
  }

省略地點名稱

Kotlin

// Omit this to hide the name.
// Non-pro fragments might also have the enum
AdvancedPlaceDetailsFragment.newInstance(
      listOf(
        //Content.NAME,
        Content.MEDIA,
        Content.ADDRESS,
        Content.RATING,
      ), orientation)

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)
