我使用过很多 Google map V2 的示例,我已经完成了所有必要的操作。但仍然有问题,只显示地图视图,我的模拟器上没有显示我当前的位置。
我已经从API控制台创建了系统MD 5密钥和API密钥,并在清单中使用了SHA 1密钥。但仍然有问题。
所以请帮助我。
我的源代码:
MainActivity.java
package com.googlev2.android;
import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
public class MainActivity extends FragmentActivity {
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment fm = (SupportMapFragment)getSupportFragmentManager().
findFragmentById(R.id.map);
mMap = fm.getMap();
mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
final LatLng CIU = new LatLng(35.21843892856462, 33.41662287712097);
Marker ciu = mMap.addMarker(new MarkerOptions().position(CIU).title("My Office"));
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
和activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

<TextView

<fragment
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
和AndroidManifest.xml:

如果您的清单文件正确请尝试此人
activity_main.xml中
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:name="com.google.android.gms.maps.SupportMapFragment"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
map:cameraTargetLat="33.41662287712097"
map:cameraTargetLng="35.21843892856462"
map:cameraZoom="4"/>
</LinearLayout>
在MainActivity.java onCreate()
中public class MainActivity extends FragmentActivity {
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = mapFragment.getMap();
mMap.addMarker(new MarkerOptions()
.position(new LatLng(35.21843892856462, 33.41662287712097))
.title("My Office"));
}
这是我手机上的结果

在包含api密钥的元数据之后,您需要添加以下行
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version"/>
我建议你证明genymotion模拟器比默认模拟器好20倍。您可以在此处找到正确设置的说明:
