android - 在谷歌地图项目中膨胀类 fragment 时出错

Question

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

Answer 1

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" />
