请帮助：android.view.InflateException：二进制XML文件行＃3：错误膨胀类com.google.android.maps.MapView
问题描述：
我写了Get Point应用程序（https://market.android.com/details?id=jv.android.getpoint&feature=search_result）来存储GPS坐标并将KML文件导出到在Google地球中打开。该应用程序的创建是因为我需要学习Android平台。请帮助：android.view.InflateException：二进制XML文件行＃3：错误膨胀类com.google.android.maps.MapView
因为我是Android新手，请原谅我，如果我要求一个虚拟的问题。 :)
的谷歌已标记的开发者控制台显示我有，我不能由我自己无论是在模拟器再现误差（与谷歌APU，银河S或银河5 :(
的错误信息是：机器人.view.InflateException：二进制XML文件行＃3：错误充气类com.google.android.maps.MapView
我一直在寻找一个解决方案，但未能找到答案:(

主要活动有一个调用MapActivity的菜单选项。在XML和代码：
要启动地图：
Intent intent = new Intent(GetPointActivity.this, PointView.class);
intent.putExtra("latitude", latitude);
intent.putExtra("longitude", longitude);
startActivity(intent);
的PointView类：
public class PointView extends MapActivity {
MapView mv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.maps);
mv = (MapView)findViewById(R.id.mvPosicao);
mv.setLongClickable(true);
mv.setBuiltInZoomControls(true);
Intent intent = getIntent();
if (intent != null)
{
Bundle params = intent.getExtras();
if (params != null) {
Double lat = (Double) params.getDouble("latitude");
Double lon = (Double) params.getDouble("longitude");
markPosition (lat, lon);
}
}
registerForContextMenu(mv);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
//Log.i("MYINFO", "I'm in");
MenuItem mi0 = menu.add(Menu.NONE, 0, 0, getString(R.string.mnVerMapa));
mi0.setIcon(R.drawable.mapview);
MenuItem mi1 = menu.add(Menu.NONE, 1, 1, getString(R.string.mnVerSatelite));
mi1.setIcon(R.drawable.satelliteview);
MenuItem mi2 = menu.add(Menu.NONE, 2, 2, getString(R.string.mnVerStreetView));
mi2.setIcon(R.drawable.streetview);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 0:
mv.setSatellite(false);
break;
case 1:
mv.setSatellite(true);
break;
case 2:
mv.setStreetView(true);
break;
}
return true;
}
public void markPosition (Double lat, Double lon){
int latE6 = (int)(lat*1E6);
int lonE6 = (int)(lon*1E6);
GeoPoint point = new GeoPoint(latE6, lonE6);
ImageOverlay io = new ImageOverlay(new GeoPoint(latE6, lonE6), R.drawable.waypoint2);
mv.getOverlays().add(io);
mv.getController().setCenter(point);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
}
的PointView 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">

android:id="@+id/mvPosicao"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="<my googlemaps key" />
</LinearLayout>
我的清单：

</manifest>
显示地图的选项由用户长按ListView时显示的上下文菜单调用。也就是说ListView中有一个自定义适配器（突出显示的行是在堆栈显示）：
public class ListaCoordAdapter extends ArrayAdapter<CoordToShow> {
private List<CoordToShow> items;
Context context;
public ListaCoordAdapter(Context context, int textViewResourceId, List<CoordToShow> items) {
super(context, textViewResourceId, items);
this.items = items;
this.context = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
**v = vi.inflate(R.layout.rowcoord, null);**
}
CoordToShow it = items.get(position);
if (it != null) {
ImageView iv = (ImageView) v.findViewById(R.id.ivCoord);
TextView l1 = (TextView) v.findViewById(R.id.linha1);
TextView l2 = (TextView) v.findViewById(R.id.linha2);
l1.setText(it.getNome());
l2.setText(it.toString());
if (iv != null) {
if (it.getTipo() == CoordToShow.PONTO)
iv.setImageResource(R.drawable.waypoint2);
else
iv.setImageResource(R.drawable.track);
}
}
return v;
}
}
的rowcoord的xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:paddingTop="4dip"
android:paddingBottom="6dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:orientation="horizontal">
<ImageView android:src="@drawable/waypoint2" android:id="@+id/ivCoord" android:layout_width="32dp" android:layout_height="32dp"></ImageView>
<LinearLayout
android:id="@+id/ll2"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:orientation="vertical">
<TextView android:id="@+id/linha1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/linha2"></TextView>
</LinearLayout>
</LinearLayout>
在Default.Property：
target=Google Inc.:Google APIs:8
任何帮助将不胜感激。

问题的核心是堆栈跟踪的最底部：MapViews can only be created inside instances of MapActivity。基本上，通货膨胀是出于任何原因从您的PointView外部进行的。
是jv.android.getpoint.ListaCoordAdapter您的课程之一？它从栈跟踪看，这是试图膨胀布局的类。如果这个类是你的，它是否扩展了MapActivity？

谢谢。我添加了ListaCoordAdapter类和Default.Properties值。 ListaCoordAdapter只是一个ListView的新适配器，而不是MapView。我在堆栈中看到了，但我不明白为什么？ :( –

任何机会，你可以得到完整的堆栈跟踪（没有'... 43更多'）？也许还有另一个线索 –

该跟踪来自谷歌市场我无法在我的设备/计算机中重现错误： （ –

我固定它通过在调用的MapView
是什么在你'default.properties'文件中的活动类扩展MapActivity而不是活动？ – inazaruk
