Android Google Map - Lỗi khi làm tăng phân đoạn lớp học

Question

Tôi đang cố gắng hiển thị GoogleMap trên số Activity của mình. Tôi đã thực hiện tất cả các bước cần thiết bao gồm tạo khóa, liên kết google-play-services_lib, đã thêm android-support-v4.jar. Nhưng tôi đang gặp lỗi vì số Fragment. Tôi đã thử nhiều giải pháp, đã dành nhiều giờ nhưng không thể giải quyết vấn đề này. Làm ơn giúp tôi.

MapActivity.java

package com.example.classified_android_app; 

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 

public class MapActivity extends FragmentActivity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.map); 
    } 
} 

map.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <fragment 
     xmlns:map="http://schemas.android.com/apk/res-auto" 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     class="com.google.android.gms.maps.SupportMapFragment" 
     map:cameraTargetLat="17.660324"

Answer 1

Vấn đề chính là bạn android:minSdkVersion="16"

gì tài liệu ban đầu cho biết là

Nếu bạn android:minSdkVersion > 12 thì bạn nên sử dụng MapFragment với mở rộng Activity

Và

Nếu android:minSdkVersion < 12 của bạn thì bạn nên sử dụng SupportMapFragment với mở rộng FragmentActivity

Answer 2

Cố gắng thay thế

<fragment 
     xmlns:map="http://schemas.android.com/apk/res-auto" 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     class="com.google.android.gms.maps.SupportMapFragment" 
     map:cameraTargetLat="17.660324" 
     map:cameraTargetLng="75.906601" 
     map:cameraZoom="15" > 
    </fragment> 

với

<fragment 
     xmlns:map="http://schemas.android.com/apk/res-auto" 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:name="com.google.android.gms.maps.SupportMapFragment" 
     map:cameraTargetLat="17.660324" 
     map:cameraTargetLng="75.906601" 
     map:cameraZoom="15" > 
    </fragment>

Answer 3

Hãy thử thêm này để onCreate() của bạn.

 SupportMapFragment mapFragment = 
       (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); 
     mapFragment.getMapAsync(this); 

và thay thế điều này.

<fragment 
     xmlns:map="http://schemas.android.com/apk/res-auto" 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     class="com.google.android.gms.maps.SupportMapFragment" 
     map:cameraTargetLat="17.660324" 
     map:cameraTargetLng="75.906601" 
     map:cameraZoom="15" > 
    </fragment> 

với

<fragment 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     class="com.google.android.gms.maps.SupportMapFragment" /> 
     map:cameraTargetLat="17.660324" 
     map:cameraTargetLng="75.906601" 
     map:cameraZoom="15" > 
    </fragment>
