我开发了一个带有底部标签栏的 android 应用程序 gridview。
在这里,我编写了如下代码:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="@+id/Layout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="@+id/status"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Mercuryminds Shoppingcart Application"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#040404"
android:gravity="center" />
<GridView
android:layout_height="0dp"
android:id="@+id/gridView1"
android:layout_width="match_parent"
android:numColumns="auto_fit"
android:layout_weight="1"
android:horizontalSpacing="10dp"
android:verticalSpacing="10dp">
</GridView>
<include
android:id="@+id/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
layout="@layout/footer" />
</LinearLayout>
footer.xml 文件如下所示:
<?xml version="1.0" encoding="utf-8"?>
<TabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffffff"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:layout_width="fill_parent"
android:id="@+id/linearLayout1"
android:background="#ffffffff"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/textView1"
android:textColor="#465371"
android:gravity="center"
android:textSize="13sp"
android:textStyle="bold">
</TextView>
<TabWidget
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@android:id/tabs"
android:tabStripEnabled="false"
android:textColor="@drawable/tab_text_selector"
android:background="@drawable/tabicon" >
</TabWidget>
<FrameLayout
android:background="#ffffffff"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/tabcontent">
</FrameLayout>
</LinearLayout>
</TabHost>
这是我的主要活动 android 代码(仅 Gridview):
public class MainActivity extends Activity {
static final String URL = "http://xxxxx";
static String KEY_CATEGORY = "category";
static final String KEY_TITLE = "categoryName";
static final String KEY_THUMB_URL = "categoryImage";
static final String KEY_SUBCATE = "categoryId";
GridView lview3;
LazyAdapter adapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); // getting XML from URL
Document doc = parser.getDomElement(xml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_CATEGORY);
// looping through all song nodes <song>
for (int i = 0; i < nl.getLength(); i++) {
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String> ();
Element e = (Element) nl.item(i);
map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));
map.put(KEY_SUBCATE, parser.getValue(e, KEY_SUBCATE));
map.put(KEY_THUMB_URL, parser.getValue(e, KEY_THUMB_URL));
songsList.add(map);
}
lview3 = (GridView) findViewById(R.id.gridView1);
adapter = new LazyAdapter(this, songsList);
lview3.setAdapter(adapter);
lview3.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
HashMap<String, String> map = songsList.get(position);
Intent in = new Intent(
MainActivity.this,
com.ssmobileproductions.catalogue.SubCate.class);
in.putExtra(KEY_TITLE, map.get(KEY_TITLE));
in.putExtra(KEY_SUBCATE, map.get(KEY_SUBCATE));
startActivity(in);
}
});
}
}
我如何在这些应用程序中使用标签栏开发 gridview。请给我解决方案。
我怎样才能显示像这些图像。
