我正在尝试运行 Android MapView 示例,并在 Eclipse 中收到“无法从 View 转换为 MapView”错误。
我的布局如下
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainlayout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<com.google.android.maps.MapView
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="0jwi0saLYCPGfO-t7glg5bQoBz7jVKWCcgyQWQA"
/>
<LinearLayout
android:id="@+id/zoomview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@id/mapview"
android:layout_centerHorizontal="true"
/>
</RelativeLayout>
活动代码是
package org.gaz.mapapp;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.ZoomControls;
import com.google.android.maps.*;
public class MapView extends MapActivity {
LinearLayout linearLayout;
MapView mapView;
ZoomControls mZoom;
public void onCreate(Bundle savedInstance) {
linearLayout = (LinearLayout) findViewById(R.id.mainlayout);
mapView = (MapView) findViewById(R.id.mapview);
mZoom = (ZoomControls) mapView.getZoomControls();
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
错误是由线路引起的
mapView = (MapView) findViewById(R.id.mapview);
任何人都可以提供有关修复的建议吗?
干杯,加兹。
