Question

在我的MapView中，会显示如下气球：http：//www.codemobiles.com/forum/code-mobile-topic-4180.html（它或多或少是相同的代码）我想要的：如果我按气球1，它应打开详细信息视图，信息为1 当我按下Ballon 2时，它应该打开详细视图，其中包含2

的信息

我将其添加到Itemized Overlay： c.startActivity（new Intent（c.getApplicationContext（），QuoteDetail.class））;

因此，当我按下气球1时，打开带有信息1的DetailView 但是当我按下气球2时，它也打开带有信息1的DetailView 我怎么能改变这个？

这是我的代码： QuoteDetail：

private ImageView mImageView;
private TextView mQuote;
private TextView mInfo;
private TextView mEmail;
private TextView mTel;
private TextView mWww;
private int mPosition;
private DataSource mDataSource;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.quote_detail);

    Intent i = getIntent();
    mPosition = i.getIntExtra("position", 0);

    mDataSource = new DataSource();
    mImageView = (ImageView) findViewById(R.detail.image);
    mQuote = (TextView) findViewById(R.detail.quote);
    mInfo = (TextView) findViewById(R.detail.info);
    mEmail = (TextView) findViewById(R.detail.email);
    mTel = (TextView) findViewById(R.detail.tel);
    mWww = (TextView) findViewById(R.detail.www);

    mImageView.setImageResource(mDataSource.getmPhotoHdPool().get(mPosition));
    mQuote.setText(getResources().getString(mDataSource.getmQuotePool().get(mPosition)));
    mInfo.setText(getResources().getString(mDataSource.getmInfoPool().get(mPosition)));
    mEmail.setText(getResources().getString(mDataSource.getmEmailPool().get(mPosition)));
    mTel.setText(getResources().getString(mDataSource.getmTelPool().get(mPosition)));
    mWww.setText(getResources().getString(mDataSource.getmWwwPool().get(mPosition)));
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
   getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;  }





    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.menu_me:  startActivity(new Intent(this, AboutmeActivity.class));;
                                break;

            case R.id.menu_settings:  startActivity(new Intent(this, SettingsActivity.class));;
            break;
        }
        return true;  }

}

    private Context mContext;
    private LayoutInflater mInflator;
    private DataSource mDataSource;

    public QuoteAdapter(Context c) {
        mContext = c;
        mInflator = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mDataSource = new DataSource();

Answer 1

在Itemized Overlay onClick处理程序中，添加一个intentExtra，以便您可以将标识信息传递给QuoteDetail.class。您很可能希望使用自己的类扩展ItemizedOverlay类，添加可用于标识项的成员变量。然后只需访问这些成员变量并将它们作为intentExtras传递给QuoteDetail。

Answer 2

我也使用此链接，http://www.codemobiles.com/forum/code-mobile-topic-4180.html添加了一些代码，

MyMap.java类

public class MyMap extends MapActivity {

MapView mapView;
List<Overlay> mapOverlays;
Drawable drawable;
Drawable drawable2;
MyItemizedOverlay itemizedOverlay;
//MyItemizedOverlay itemizedOverlay2;

@Override
public void onCreate(Bundle savedInstanceState) {

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

    mapView = (MapView) findViewById(R.id.mapview);
    mapView.setBuiltInZoomControls(true);

    mapOverlays = mapView.getOverlays();

    // first overlay
    drawable = getResources().getDrawable(R.drawable.marker);
    itemizedOverlay = new MyItemizedOverlay(drawable, mapView);

    GeoPoint point = new GeoPoint((int) (51.5174723 * 1E6),
            (int) (-0.0899537 * 1E6));
    OverlayItem overlayItem = new OverlayItem(point, "Umar Shafique",
            "(here goes 1)");
    itemizedOverlay.addOverlay(overlayItem);

    GeoPoint point2 = new GeoPoint((int) (51.515259 * 1E6),
            (int) (-0.086623 * 1E6));
    OverlayItem overlayItem2 = new OverlayItem(point2, "Abdul Karim",
            "here goes 2");
    itemizedOverlay.addOverlay(overlayItem2);

    mapOverlays.add(itemizedOverlay);

    // second overlay
/*  drawable2 = getResources().getDrawable(R.drawable.marker2);
    itemizedOverlay2 = new MyItemizedOverlay(drawable2, mapView);

    GeoPoint point3 = new GeoPoint((int) (51.513329 * 1E6),
            (int) (-0.08896 * 1E6));
    OverlayItem overlayItem3 = new OverlayItem(point3, "Arslan Ilyas",
            "here goes 3");
    itemizedOverlay2.addOverlay(overlayItem3);

    GeoPoint point4 = new GeoPoint((int) (51.51738 * 1E6),
            (int) (-0.08186 * 1E6));
    OverlayItem overlayItem4 = new OverlayItem(point4, "Ahsan",
            "here goes 4");
    itemizedOverlay2.addOverlay(overlayItem4);

    mapOverlays.add(itemizedOverlay2);*/

    final MapController mc = mapView.getController();
    mc.animateTo(point2);
    mc.setZoom(16);

}

@Override
protected boolean isRouteDisplayed() {
    return false;
}

}

这里我评论一些代码，因为这里添加了两个itemizedOverlay，所以一个是注释。

和MyItemizedOverlay.java类

public class MyItemizedOverlay extends BalloonItemizedOverlay<OverlayItem> {

private ArrayList<OverlayItem> m_overlays = new ArrayList<OverlayItem>();
private Context c;

public MyItemizedOverlay(Drawable defaultMarker, MapView mapView) {
    super(boundCenter(defaultMarker), mapView);
    c = mapView.getContext();
}

public void addOverlay(OverlayItem overlay) {
    m_overlays.add(overlay);
    populate();
}

@Override
protected OverlayItem createItem(int i) {
    return m_overlays.get(i);
}

@Override
public int size() {
    return m_overlays.size();
}

@Override
protected boolean onBalloonTap(int index) {
    Toast.makeText(c, "onBalloonTap for overlay index " + index,
            Toast.LENGTH_LONG).show();

    if (index == 0) {
        c.startActivity(new Intent(c.getApplicationContext(),
                NewActivity.class));
    } else {
         c.startActivity(new Intent(c.getApplicationContext(),
         secondNewActivity.class));
    }
    return true;
}

}

这里修改代码

  if (index == 0) {
        c.startActivity(new Intent(c.getApplicationContext(),
                NewActivity.class));
    } else {
         c.startActivity(new Intent(c.getApplicationContext(),
         secondNewActivity.class));
    }
    return true;
}

按气球二，我们可以改变指数位置。我们可以通过你的意图传递索引位置。

提供您的代码，只有简单的解释。

MapView气球到DetailView
