在一个TabHost的Tab页上想显示一个ListView,为什么显示不出来?
代码如下,但运行后Tab上没有显示出有ListItem ,是哪的问题?
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myTabhost=this.getTabHost();
LayoutInflater.from(this).inflate(R.layout.activity_main,myTabhost.getTabContentView(),true);
myTabhost.addTab(myTabhost.newTabSpec("tab1").setIndicator("tab1",getResources().getDrawable(R.drawable.calendar)).setContent(R.id.tab1));
myTabhost.addTab(myTabhost.newTabSpec("tab2").setIndicator("tab2",getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.tab2));
myTabhost.addTab(myTabhost.newTabSpec("tab3").setIndicator("tab3").setContent(R.id.tab3));
listView1=(ListView) findViewById(R.id.listView1);
data=new ArrayList<Map<String,Object>>();
Map<String,Object> item;
item=new HashMap<String,Object>();
item.put("date", "2012-12-21");
item.put("item","世界末日");
data.add(item);
item.put("date", "2013-1-1");
item.put("item", "新年来临");
data.add(item);
SimpleAdapter adapter=new SimpleAdapter(this, data, android.R.layout.simple_expandable_list_item_2, new String[]{"date","item"}, new int[]{R.id.textView1,R.id.textView2});
listView1.setAdapter(adapter);
}
