我有两个标签A,B,带有相应的TabActivityA和TabActivityB。我有第三个ActivityA1,它不在选项卡上,而是来自ActivityA的中间活动。
以下是序列中的代码
public class AndroidTabLayoutActivity extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabHost = getTabHost();
// Tab for Home
TabSpec homeSpec = tabHost.newTabSpec("Home");
homeSpec.setIndicator("Home", getResources().getDrawable(R.drawable.icon_home_tab));
Intent homeIntent = new Intent(this, TabActivityA.class);
homeSpec.setContent(homeIntent);
// Tab for my cases
TabSpec helppec = tabHost.newTabSpec("Help");
// setting Title and Icon for the Tab
helppec.setIndicator("Help", getResources().getDrawable(R.drawable.icon_cases_tab));
Intent helpIntent = new Intent(this, TabActivityB.class);
mycasesspec.setContent(helpIntent);
// Adding all TabSpec to TabHost
tabHost.addTab(homeSpec); // Adding home tab
tabHost.addTab(help); // Adding help tab
}
ActivityA1 extends Activity
{
}
TabActivityA extends ActivityGroup
{
.....
Intent nextScreen = new Intent(getApplicationContext(), ActivityA1.class);
View view = getLocalActivityManager().startActivity("ActivityA1", nextScreen.addFlags(Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP)).getDecorView();
setContentView(view);
}
注意:我这样做是因为我想为ActivityA1显示相同的标签
这确实显示了ActivityA1上的标签(Home和Help),但是在单击Home选项卡时,我希望用户转到TabActivityA,但现在它只停留在ActivityA1上。
任何帮助将不胜感激!!

好吧我想我明白你现在要问的是,只需保留一个视图的arrayList,在调用SetContentView之前添加到此列表,然后当你准备好回到之前的View do SetContentView(list [count - 1] ]),还要确保删除以前的View并将其丢弃,否则它将永远存在于内存中......
