我需要在选项卡上有一个地图视图。附加的示例显示了如何在使用意图时执行此操作。现在我想更改地图视图的缩放级别。尽管我使用的是意图(或者有完全不同的解决方案),但我该怎么做?
活动代码:
public class TabMapsExample extends TabActivity {
TabHost mTabHost;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Context ctx = this.getApplicationContext();
//tab 1
mTabHost = getTabHost();
TabSpec tabSpec1 = mTabHost.newTabSpec("tab_test1");
tabSpec1.setIndicator("Map1");
Intent i1 = new Intent(ctx, MapTabView.class);
tabSpec1.setContent(i1);
mTabHost.addTab(tabSpec1);
//tab2
mTabHost = getTabHost();
TabSpec tabSpec2 = mTabHost.newTabSpec("tab_test1");
tabSpec2.setIndicator("Map2");
Intent i2 = new Intent(ctx, MapTabView.class);
tabSpec2.setContent(i2);
mTabHost.addTab(tabSpec2);
//tab 3
mTabHost = getTabHost();
TabSpec tabSpec3 = mTabHost.newTabSpec("tab_test1");
tabSpec3.setIndicator("Map");
Intent i3 = new Intent(ctx, MapTabView.class);
tabSpec3.setContent(i3);
mTabHost.addTab(tabSpec3);
}
}
布局代码:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/maptablayout" android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent"
android:background="#000000" android:orientation="vertical">
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="50px"
android:id="@+id/textview" />
<com.google.android.maps.MapView
android:id="@+id/mapview" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:clickable="true"
android:apiKey="" />
</LinearLayout>
</RelativeLayout>
谢谢
