嗨,我正在设置一个Android应用程序,我正在使用选项卡式界面。我想要三个标签,一个基于文本的标签(关于),一个webkit标签(商店)和一个图像的网格视图标签(图库),如Gridview tutorial。
我的文本和webkit选项卡工作正常,但我无法找出在选项卡中格式化gridview的最佳方法。以tabbed interface tutrial为例,我在主类的onCreate()事件中声明了tab的内容。
public class Woodroid extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
tabHost.setCurrentTab(0);
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, AboutActivity.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("about").setIndicator("",
res.getDrawable(R.drawable.ic_tab_about))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, StoreActivity.class);
spec = tabHost.newTabSpec("store").setIndicator("Store",
res.getDrawable(R.drawable.ic_tab_store))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, GalleryActivity.class);
spec = tabHost.newTabSpec("gallery").setIndicator("Gallery",
res.getDrawable(R.drawable.ic_tab_gallery))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
}
那么在GalleryActivity.java中我有以下
public class GalleryActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GridView gridview = new GridView(this);
gridview.setAdapter(new ImageAdapter(this));
setContentView(gridview);
}
}
这是gridview教程的解释。那时缺少的是gridview布局定义。似乎我可以强制一些属性,如
gridview.setNumColumns(3);
但这不允许从gridview版本的/layout/main.xml中获得更灵活的equivelant
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:columnWidth="90dp"
android:numColumns="auto_fit"
答案 0 :(得分:0)
确保使用FrameLayout,cf tabbed example,设置android:layout_width =“WRAP_CONTENT”而不是fill_parent,然后在每个对象元素上使用重力和重量,直到它看起来如你所愿。
