我正在尝试开展一项活动。这是我的代码:
btnShowOnMap.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Intent i = new Intent(getApplicationContext(),
PlacesMapActivity.class);
// Sending user current geo location
i.putExtra("user_latitude", Double.toString(gps.getLatitude()));
i.putExtra("user_longitude", Double.toString(gps.getLongitude()));
// passing near places to map activity
i.putExtra("near_places", nearPlaces);
// staring activity
startActivity(i);
}
});
Manifest xml文件如下所示:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.androidhive.googleplacesandmaps"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<!-- Add Google Map Library -->
<uses-library android:name="com.google.android.maps" />
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- SinglePlaceActivity -->
<activity android:name=".SinglePlaceActivity" android:label="Place Details">
</activity>
<!-- PlacesMapActivity -->
<activity android:name=".PlacesMapActivity" android:label="Near Places Map View">
</activity>
</application>
<!-- Internet Permissions -->
<uses-permission android:name="android.permission.INTERNET" />
<!-- Network State Permissions -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!-- Access Location -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
它编译没有问题,但是当我想创建一个新的intent时,我在线程“main”java.lang.NoClassDefFoundError:com / androidhive / googleplacesandmaps / PlacesMapActivity Error中得到一个Exception。有人知道可能导致问题的原因吗?
答案 0 :(得分:0)
这是一个链接问题。如果您使用eclipse,请确保将正确的jar文件添加到项目中。另外,请确保正确定义类路径
