如何在活动中使用mapView？

Question

在我的应用程序中，可以使用其他布局在主XML中包含两个视图，其中第一个视图仅具有简单的文本视图，第二个视图中具有地图视图。在我的主XML文件中，当我单击第一个按钮以显示时有两个按钮带有文本视图的第一个视图，当我单击第二个按钮时，我想隐藏第一个视图并以地图视图显示第二个视图。我不知道如何在主要活动中显示地图视图。有谁知道请帮助我解决这个问题。

Answer 1

Firstly tell what version of google maps do you use v1 - https://developers.google.com/maps/documentation/android/v1/ v2 - https://developers.google.com/maps/documentation/android/start

Usually what you need to do is to put you two layouts inside FrameLayout and show/hide one of them when you click on particular button. But to be more specific we need to see your code.

Answer 2

1) MapView is used by GoogleMapsV1. But it needs an api key provided by google for individual developers upon registration.

Unfortunately, which is closed by google and you have to use GoogleMapV2 with new V2 key.

Also, workout with fragments because, here we are using Fragment or SupportFragment.

2) You can use a FrameLayout inside which your two overlapped views with id's. So that you can show or hide views at same position as you need.

Please try to use bellow code.

<LinearLayout
    android:id="@+id/buttonLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="button1" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="button2" />
</LinearLayout>

<ViewFlipper
    android:id="@+id/viewFliper"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/buttonLayout" >

    <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <com.google.android.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:apiKey="your map key map_key"
        android:clickable="true"
        android:enabled="true"
        android:focusable="true"
        android:focusableInTouchMode="true" />
</ViewFlipper>
