我是 Android 新手。我正在构建一个具有 5 个选项卡的选项卡式应用程序。我使用不同的视图组，每个选项卡都有根据需要和子活动的可响应视图组。第一个选项卡是具有不同子活动的 TabGroupHome。TabGroupHome 首先启动 GoogleMapActivity （具有overlayItems）作为其子活动。这些叠加层代表了不同的用户。我从一个 JSONArray 中获取这些用户的数据，该 JSONArray 由服务器上的一个 php 文件返回，该文件具有不同用户的数据。当我启动我的应用程序时，它的外观->
发射视图！
它在顶部有一个具有不同按钮的操作栏（例如，列表、配置文件和刷新）。当我单击列表时，它会显示所有用户的列表->
＆当我单击 listItem 时，它会显示上面指出的响应用户的完整配置文件
我坚持的地方是-> ??? 当我点击 MapPin 时，我想显示此用户个人资料...
我的代码是->
public class GoogleMapActivity extends MapActivity implements ActionBar {
Button btnOnMapList, btnProfileHome, btnRefresh;
Intent intent;
private JSONArray jArray;
private JSONObject jFan_Data;
private ItemBean bean;
private FansData fansdata;//reference of FansData class that return me JSONArray
HelloItemizedOverlay itemizedOverlay;//..........
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
btnProfileHome = (Button) findViewById(R.id.btn_profile_home);
btnOnMapList = (Button) findViewById(R.id.btn_list_home);
btnRefresh = (Button) findViewById(R.id.btn_refresh_home);
super.onCreate(savedInstanceState);
setContentView(R.layout.googlemapactivity);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapView.displayZoomControls(true);
// mapView.setSatellite(true);
/**TG_1 -> Here i write code to get my current location(e.g., through LocationManager)
* after getting location, i write my location`s latitude & longitude into
* shearedPreference */
//geading preference to get my unique id
SharedPreferences myUid=GoogleMapActivity.this.getSharedPreferences("uid", MODE_WORLD_READABLE);
String myId=myUid.getString("myId", "");
Log.i("MyUid", myId);
/** calling FansData class to get all users data. Currently i am providing my hard codded location but i have to get it from LocationManager */
fansdata=new FansData();
jArray=fansdata.jFanDataArray(1000, 12.9716060, 77.5903760, "h9ow0");
System.out.println(jArray.toString());
/** to showing Users on map as pins */
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = this.getResources().getDrawable(
R.drawable.small_football_icon);
HelloItemizedOverlay itemizedOverlay = new HelloItemizedOverlay(
drawable, getParent());
for(int i=0;i<jArray.length();i++){
try {
jFan_Data=jArray.getJSONObject(i);
GeoPoint geoPoint = new GeoPoint((int) (jFan_Data.getDouble("lat")* 1E6),
(int) (jFan_Data.getDouble("lang")* 1E6));
OverlayItem overlayitem = new OverlayItem(geoPoint, jFan_Data.getString("name"),
jFan_Data.getString("uniqid"));
itemizedOverlay.addOverlay(overlayitem);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
mapOverlays.add(itemizedOverlay);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
@Override
public void onHomeList(View view) {
Intent in = new Intent(getParent(), MapPinsList.class);
TabGroupActivity prnt = (TabGroupActivity) getParent();
prnt.startChildActivity("MapPinsList", in);
}
@Override
public void onHomeProfile(View view) {
Intent in = new Intent(getParent(), ProfileActivity.class);
TabGroupActivity prnt = (TabGroupActivity) getParent();
prnt.startChildActivity("ProfileActivity", in);
}
@Override

@Override
public void onListMap(View view) {

@Override

}
我的 HelloItemizedOverlay 类是->
public class HelloItemizedOverlay extends ItemizedOverlay {
private static final int VIEW_PROFILE = 1;
private static final int SEND_MASSAGE = 2;
OverlayItem item;
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
Context mContext;
public HelloItemizedOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
}
public HelloItemizedOverlay(Drawable defaultMaker, Context context) {
// super(defaultMaker);
super(boundCenterBottom(defaultMaker));
mContext = context;
}
@Override
public boolean onTap(int index) {
// Option to select on clicking pin
final String[] option = new String[] { "View Profile", "Send Massage",
"Cancle" };
// to hold option
ArrayAdapter<String> adapter = new ArrayAdapter<String>(mContext,
android.R.layout.select_dialog_item, option);
//OverlayItem item = mOverlays.get(index);
item = mOverlays.get(index);
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setTitle(item.getTitle());
// builder.setMessage(item.getSnippet());
builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int i) {
// TODO Auto-generated method stub
if (i == 0) {
String fId=item.getSnippet();
Toast.makeText(mContext, "Profile View is on Progress...!"+fId,
Toast.LENGTH_SHORT).show();
Intent in = new Intent(mContext, FanProfile.class);
Bundle fBundle= new Bundle();
fBundle.putString("fanId", fId);
in.putExtras(fBundle);
in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.getApplicationContext().startActivity(in);
} else if (i == 1) {
Toast.makeText(mContext,"Send Massage View is on Progress...!",
Toast.LENGTH_SHORT).show();
} else if (i == 2) {
dialog.cancel();
}
}
});
builder.show();
// AlertDialog dialog= builder.create();
return true;
}
public void addOverlay(OverlayItem overlayItem) {
// for(int i=0;i<=size();i++){
mOverlays.add(overlayItem);
populate();
// }
}
@Override
protected OverlayItem createItem(int i) {
// TODO Auto-generated method stub
return mOverlays.get(i);
}
@Override
public int size() {
// TODO Auto-generated method stub
return mOverlays.size();
}
}
“onTap”中的 FanProfile 与我单击用户列表的 listItem 时调用的活动相同！
上面的代码有效，但它在我的 tabView 上启动视图，它隐藏了我的选项卡...

我没有得到我犯错或做错的地方。
你的建议对我很有价值！！！
我将不胜感激获得解决此问题的指针或示例代码...
