Question

我知道他们是一些帖子，也有同样的问题。我已经读完了所有这些，但这并没有解决我的问题。这是我的AndroidManifest.XML

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="my.first.project"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="8" />

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

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <uses-library android:name="com.google.android.maps" />

    <activity
        android:name=".GPS"
        android:label="@string/app_name" >

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

    </activity>

    <activity android:name=".About"
              android:label="@string/about_title" />
    <activity android:name=".getGPS"
              android:label="@string/get_gps" />
</application>
</manifest>

这是XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText
android:id="@+id/id1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My text edit this."
/>
<com.google.android.maps.MapView
android:id="@+id/myGMap"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="0VeISgtB_USJi-BUVme-Zmbo7st7ED2Pf3TAv**"
/>
</LinearLayout>

这是日志：

我收到“强制关闭”警告。

有什么建议吗？

public class getGPS extends MapActivity implements LocationListener 
{    
EditText txted = null;
Button btnSimple = null;
MapView gMapView = null;
MapController mc = null;
Drawable defaultMarker = null;

double latitude = 10, longitude = 10;

@Override
public void onCreate(Bundle savedInstanceState)

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.getgps);

    // Creating TextBox displying Lat, Long
    txted = (EditText) findViewById(R.id.id1);
    String currentLocation = "Lat: " + latitude + " Lng: " + longitude;
    txted.setText(currentLocation);

    // Creating and initializing Map
    gMapView = (MapView) findViewById(R.id.myGMap);
    p = new GeoPoint((int) (latitude * 1000000), (int) (longitude * 1000000));

    mc.setCenter(p);
    mc.setZoom(14);

    list.add(myLocationOverlay);

Answer 1

你可以在视图中尝试这样的地图

<view android:id="@+id/mapview"
 class="com.google.android.maps.MapView"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:layout_weight="1" 
 android:clickable="true"
 android:apiKey="key"
/>

我认为它的观点问题。

Answer 2

在您的 AndroidManifest.XML 中，我认为您声明了错过匹配的名称..（class getGPS extends MapActivity，但您声明了android:name=".GPS"）

 <activity
        android:name=".getGPS"
        android:label="@string/app_name" >

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

    </activity>

修改

确保您的班级名称和您在android:name中声明的名称相同。

例如，如果您的课程为getGPS，则应在清单android:name=".getGPS"中声明，如上例所示。

Answer 3

解决了！这是源代码，它帮助了我：

http://code.google.com/p/androidannotations/issues/detail?id=73

原因是我在setContentView（）之前编写了super.OnCreate（）它应该是这样的：

super.onCreate(savedInstanceState);
setContentView(R.layout.getgps);
