我在选项卡视图中有问题。我必须显示许多导航选项卡视图。例如。在第一个名为“Sales”的选项卡中，它列出了所有的销售路线。如果用户单击一个路线，它需要像WISE ITS GO一样在第一个选项卡中列出零售商。有许多页面（视图）可用。
从第一个视图中的my it-only-show选项卡，这意味着当它加载tab时，它显示了带有tab视图的销售路线列表。当我单击Sales Route时，它显示Retailer，但不显示选项卡视图。
这是我的代码：tabview.xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost">
<LinearLayout android:id="@+id/LinearLayout01"
android:orientation="vertical" android:layout_height="fill_parent"
android:layout_width="fill_parent">
<TabWidget android:id="@android:id/tabs"
android:layout_height="wrap_content" android:layout_width="fill_parent"></TabWidget>
<FrameLayout android:id="@android:id/tabcontent"
android:layout_height="fill_parent" android:layout_width="fill_parent"></FrameLayout>
</LinearLayout>
这是我的主要活动：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabview);
TabHost t = getTabHost();
TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);
TabSpec firstTabSpec = tabHost.newTabSpec("tid1");
TabSpec secondTabSpec = tabHost.newTabSpec("tid1");
TabSpec thirdTabSpec = tabHost.newTabSpec("tid1");
/** TabSpec setIndicator() is used to set name for the tab. */
/** TabSpec setContent() is used to set content for a particular tab. */
firstTabSpec.setIndicator("Sales").setContent(new Intent(this,SalesRouteActivity.class));
secondTabSpec.setIndicator("Admin").setContent(new Intent(this,SalesRoutesTab.class));
thirdTabSpec.setIndicator("Setting").setContent(new Intent(this,SalesRoutesTab.class));
/** Add tabSpec to the TabHost to display. */
tabHost.addTab(firstTabSpec);
tabHost.addTab(secondTabSpec);
tabHost.addTab(thirdTabSpec);
}
这是我的销售活动；
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sales_routes);
ArrayList<Object> routeList = getWmRoute();
ArrayList<String> routhPath = new ArrayList<String>();
for(int i = 0; i<routeList.size();i++){
routhPath.add(((WMRoute) routeList.get(i)).getDescription());
}
ArrayAdapter ad = new ArrayAdapter(this,android.R.layout.simple_list_item_single_choice,routhPath);
setListAdapter(ad);
final ListView list=getListView();
list.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
list.setItemsCanFocus(true);
list.setTextFilterEnabled(true);
list.setItemChecked(positions,true);
keyword = (String) list.getItemAtPosition(0);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add("OK");
menu.add("Cancel");
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 0:
Intent showContent = new Intent(getApplicationContext(),ListRetailerActivity.class);
Bundle bundle = new Bundle();
bundle.putString("RouteName", keyword);
showContent.putExtras(bundle);
startActivity(showContent);
return true;
case 1:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
这是零售商零件清单零售商活动；
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.retailer_list);
Bundle bundle = this.getIntent().getExtras();
String routeName = bundle.getString("RouteName");
setTitle(routeName + " - List Retailer ");
ArrayList<Object> routeList = getWmRoute();
// ArrayList<String> routhPath = new ArrayList<String>();
ArrayList<HashMap<String,String>> alist=new ArrayList<HashMap<String,String>>();
for(int i = 0; i<routeList.size();i++){
HashMap<String, String> map = new HashMap<String, String>();
map.put("RetailerCode", ((WMRoute) routeList.get(i)).getDescription());
map.put("RetailerName", ((WMRoute) routeList.get(i)).getBusinessUnit());
alist.add(map);
}
ListView list=getListView();
sd = new SimpleAdapter(this,alist,R.layout.retalier_rows,new String[]{"RetailerCode","RetailerName"},new int[]{R.id.retailerCode,R.id.retailerName});
list.setAdapter(sd);
list.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
list.setSelected(true);
list.setSelection(0);
list.setTextFilterEnabled(true);
list.setItemsCanFocus(true);
list.setTextFilterEnabled(true);
list.setItemChecked(positions,true);
keyword = ((WMRoute) routeList.get(0)).getBusinessUnit();
//keyword = (String) list.getItemAtPosition(0);
}
在这里我要展示listactivity和tabactivity，我们如何实现它。
所有子活动都需要显示选项卡视图。
请帮助我如何调用其他XML以使用选项卡视图进行导航。
提前谢谢。
最佳答案
好的，我正在提供一个演示我希望它能帮助你…
所有人中的第一个都声明一个ActivityGroup像这样SalesActivityGroup.java
public class SalesActivityGroup extends ActivityGroup {
// Keep this in a static variable to make it accessible for all the nested activities, lets them manipulate the view
public static SalesActivityGroup group;
// Need to keep track of the history if you want the back-button to work properly, don't use this if your activities requires a lot of memory.
private ArrayList<View> history;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.history = new ArrayList<View>();
group = this;
// Start the root activity withing the group and get its view
View view = getLocalActivityManager().startActivity("Home", new
Intent(this,SalesRouteActivity.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
// Replace the view of this ActivityGroup
replaceView(view);
}
public void replaceView(View v) {
// Adds the old one to history
history.add(v);
// Changes this Groups View to the new View.
setContentView(v);
}
public void back() {
if(history.size() > 0) {
history.remove(history.size()-1);
if(history.size() > 0) {
setContentView(history.get(history.size()-1));
}
else {
finish();
}
}else {
finish();
}
}
@Override
public void onBackPressed() {
SalesActivityGroup.group.back();
return;
}
}
在此更改之后，您的主机（mainActivity）（只更改一个tabspec:firsttabspec，我猜它与销售有关）如下…
public class Host extends TabActivity {
public static Button btnRed;
public static TabHost tabHost;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.host);
tabHost = (TabHost)findViewById(android.R.id.tabhost);
TabSpec salesTabSpec = tabHost.newTabSpec("tid1");
Intent intent1 = new Intent(this, SalesActivityGroup.class);//SalesActivityGroup instead of SalesRouteActivity
salesTabSpec.setContent(intent2);
/* Add tabSpec to the TabHost to display. */
tabHost.addTab(salesTabSpec);
}
}
之后，当您想在firsttab（salestab）中启动新活动时，只需更改与该salestab相关的活动组的视图
像这样（从下面开始你的ListRetailerActivity）……
Intent intent = new Intent(SalesRouteActivity.this, ListRetailerActivity.class);
// Create the view using FirstGroup's LocalActivityManager
View view = SalesActivitytGroup.group.getLocalActivityManager()
.startActivity("", intent
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
// Again, replace the view
SalesActivityGroup.group.replaceView(view);
