Question

我正在尝试一周时间来设置我的Google Map v2。但它不适合我。我尝试了与之相关的问题的答案，但没有用。我无法追踪确切的问题。请帮忙。这是我的xml文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
<fragment 
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.SupportMapFragment"/>
</RelativeLayout>

在我的map.class中我有

import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.maps.*;
import android.support.v4.app.FragmentActivity;  
import com.google.android.gms.maps.SupportMapFragment;
import android.app.Activity;
import android.app.Dialog;
import android.support.v4.app.Fragment;
import android.widget.Toast;
import android.os.Bundle;

public class Map extends Activity {

    private GoogleMap googleMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);
        if (googleMap == null) {
            googleMap = ((MapFragment)     getFragmentManager().findFragmentById(
                R.id.map)).getMap();

            // check if map is created successfully or not
            if (googleMap == null) {
                Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
            }
        }

    }
    }

我的API密钥是正确的，我根据指示导入了google play服务库。在我的清单文件中

<permission
        android:name="com.example.sellatease.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="com.example.sellatease.permission.MAPS_RECEIVE" />

       <uses-sdk
        android:minSdkVersion="21"
        android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

         <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

和

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />
     <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyCwHLxfMRBnD_MJDQDV9IYBZTxbkCVlZsA" />

This is my error log

在控制台中我找不到googleplayserviceslib.apk错误。

Answer 1

如果您使用 SupportMapFragment ，则需要扩展 FragmentActivity / AppCompatActivity 。

public class Map扩展了FragmentActivity / AppCompatActivity {

   FragmentManager myFragmentManager = getSupportFragmentManager();
   SupportMapFragment mySupportMapFragment  = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
   googleMap = mySupportMapFragment.getMap();

您可以查看 Android Map V2

Answer 2

试试这个

googleMap = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
