我正在开发一个在屏幕上显示 Google map 的项目。我根据互联网帮助做了每一件事，我也按照教程进行操作，但我没有解决问题这是我的项目..
主要 Activity .java
package com.appscourt.jogging.track.map.health;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.widget.Toast;
public class MainActivity extends Activity {
// Google Map
private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* function to load map. If map is not created it will create it for you
* */
private void initilizeMap() {
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();
}
}
}
@Override
protected void onResume() {
super.onResume();
initilizeMap();
}
}

谁能帮帮我...
提前致谢
最佳答案
我的 XML
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".CarLiveTrackingMapScreen" >
<fragment
android:id="@+id/tracking_screen_map"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="@id/tracking_screen_header_rl"
class="com.google.android.gms.maps.SupportMapFragment" />
</RelativeLayout>
类文件你应该扩展FragmentActivity
public class LiveTrackingActivity extends FragmentActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.live_tracking_activity);
FragmentManager myFragmentManager = getSupportFragmentManager();
SupportMapFragment mySupportMapFragment = (SupportMapFragment) myFragmentManager
.findFragmentById(R.id.tracking_screen_map);
myMap = mySupportMapFragment.getMap();
myMap.getUiSettings().setZoomControlsEnabled(true);
myMap.getUiSettings().setCompassEnabled(true);
myMap.getUiSettings().setRotateGesturesEnabled(true);
myMap.getUiSettings().setMyLocationButtonEnabled(true);
}
}
将此代码添加到您的 XML 文件中
<uses-library
android:name="com.google.android.maps"
android:required="true" >
</uses-library>
<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="AIzaSyB6krIcZoYtN73-l8ijuwkbCw-yhLfp7DY" />
