我想在Android中动态创建一个标签,在每个标签下我都有一个列表视图。所以我希望listview的内容也动态变化。我怎么能这样做?

我在另一个论坛上看到了一个代码并将其清理干净了一点。为了做你需要的事,你必须改变ts1.setContent和ts2.setContent里面的东西
<强> Main_screen.java 强>
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class Main_screen extends Activity{
private ListView ls1;
private ListView ls2;
private TabHost myTabHost;
@Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.main);
myTabHost = (TabHost)this.findViewById(R.id.th_set_menu_tabhost);
myTabHost.setup();
ls1 = new ListView(Main_screen.this);
TabSpec ts1 = myTabHost.newTabSpec("TAB_TAG_1");
ts1.setIndicator("Tab1");
ts1.setContent(new TabHost.TabContentFactory(){
public View createTabContent(String tag)
{
ArrayAdapter<String> adapter = new ArrayAdapter<String>(Main_screen.this,android.R.layout.simple_list_item_1,new String[]{"item1","item2","item3"});
ls1.setAdapter(adapter);
return ls1;
}
});
myTabHost.addTab(ts1);
ls2 = new ListView(Main_screen.this);
TabSpec ts2 = myTabHost.newTabSpec("TAB_TAG_2");
ts2.setIndicator("Tab2");
ts2.setContent(new TabHost.TabContentFactory(){
public View createTabContent(String tag)
{
ArrayAdapter<String> adapter = new ArrayAdapter<String>(Main_screen.this,android.R.layout.simple_list_item_1,new String[]{"item4","item5","item6"});
ls2.setAdapter(adapter);
return ls2;
}
});
myTabHost.addTab(ts2);
}
}
<强> main.xml中强>
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/th_set_menu_tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="64dip" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="75dip">
<ListView
android:id = "@+id/danhsach"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</FrameLayout>
</TabHost>

for(int i=0; i<5; i++ )
{
final TabSpec x=tabHost2.newTabSpec("x");
View row = inflater.inflate(R.layout.indicator1,null);
final TextView indicator1 =(TextView) row.findViewById(R.id.textView_indicator1);
indicator1.setText(indicator_list[i]);
// indicator1.setShadowLayer(1, 0, 1, 0xFF013201);
x.setIndicator(row);
x.setContent(new TabContentFactory() {
public View createTabContent(String arg) {
return gallery2;
}
});
tabHost2.addTab(x);
}
你可以这样做。
