地点自动完成 Android
Places Autocomplete Android
我是 Android 开发新手。
我正在努力自动完成用户输入。我需要一个 google 地图,例如用户输入的自动完成。用户需要 select 地址、地点、街道 a.s.o。来自自动完成,我需要它的 LatLng。
我试图通过使用 google course 来完成此操作,但这并不是我想要的。我不想拥有整个片段或仅用于 select 某个地方的东西,我正在寻找 AutoCompleteTextView
解决方案。有没有简单易懂的方法来做到这一点?
我找到了 this,但这看起来不像 "normal way" 那样做,还是我错了?这是网络 API 电话而不是 Android API 电话,不是吗?

只是坚持 Google 的地方自动完成如果你想要它就像 AutoCompleteTextView.its MODE_OVERLAY 选项一样,只需执行以下操作。
Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
.build(mActivity);
startActivityForResult(intent, REQUEST_CODE_AUTOCOMPLETE);
使用它来创建自定义地点建议并处理数据。下面是 Activity,它在 AutoCompleteTextView

如果有人知道解决方案,请告诉我 know.Currently 我使用了 android 自动完成
搜索 process.But 仍在努力将旧的自动完成地点搜索迁移到新的。
我是 Android 开发新手。
我正在努力自动完成用户输入。我需要一个 google 地图,例如用户输入的自动完成。用户需要 select 地址、地点、街道 a.s.o。来自自动完成,我需要它的 LatLng。
我试图通过使用 google course 来完成此操作,但这并不是我想要的。我不想拥有整个片段或仅用于 select 某个地方的东西,我正在寻找 AutoCompleteTextView
解决方案。有没有简单易懂的方法来做到这一点?
我找到了 this,但这看起来不像 "normal way" 那样做,还是我错了?这是网络 API 电话而不是 Android API 电话,不是吗?
