异常与标签：＆QUOT;必须指定一个方法来创建选项卡指示器＆QUOT; [英] Exception with Tabs: "you must specify a way to create tab indicator"

问题描述

我的应用程序由三个选项卡，其中两个有ListView和一种是与TextView的只是活动。要使用标签获取主要活动我使用developers.anroid.com HTTP的例子：//developer.android.com/resources/tutorials/views/hello-tabwidget.html
根据这个例子我的布局是：

My application consists three tabs and two of them have the ListView and one is just activity with TextView. To get main activity with Tabs I use the example from developers.anroid.com http://developer.android.com/resources/tutorials/views/hello-tabwidget.html According to this example my layout is:

<?xml version="1.0" encoding="utf-8"?>
<TabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/tabhost"
>

<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>

<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>

<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>


</LinearLayout>

</TabHost>

所以，下次code是活动的code（只有两页）：

So, next code is code of activity (there are only two pages):

public class MainActivity extends TabActivity {



@Override
public void onCreate(Bundle savedInstanceState) 
{

    super.onCreate(savedInstanceState);
    setContentView(R.layout.tabs_layout_start_page);

    Resources res = getResources();
    TabHost tabHost = getTabHost();
    TabHost.TabSpec spec;
    Intent intent;

    intent = new Intent(this, ListViewTab1Activity.class);
    spec = tabHost.newTabSpec("Page1").setIndicator("Page 1", res.getDrawable(R.drawable.icon))
    .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent(this, ListViewTab2Activity.class);
    spec = tabHost.newTabSpec("Page 2").setIndicator("Page 2", res.getDrawable(R.drawable.icon))
    .setContent(intent);
    tabHost.addTab(spec);

    tabHost.setCurrentTab(1);

}

}

每一个意图指向另一个活动，该公司在布局和code硬codeD的ListView来从资源字符串数组定义它。但启动后，我得到异常
IllegalArgument异常，你必须指定一个方法来创建选项卡指示器。这让我停了下来，请帮助我。
感谢大家。

Every intent is pointed to another activity, which has hard-coded ListView in layout and code to define it from string-array from resources. But after starting I get exception IllegalArgument Exception ""you must specify a way to create tab indicator". and it makes me stopped, please, help me. thanks for everyone

推荐答案

我只是有这个同样的问题。

I just had this same problem.

我发现我的问题是SP的重用

I found my problem was the reuse of sp

我这样做是为了解决问题：

I did this to solve the problem:

TabSpec spec1=tabHost.newTabSpec("Tab 1");
    spec1.setContent(R.id.tab1);
    spec1.setIndicator("Tab 1",getResources().getDrawable(R.drawable.icon_tab1_config));

TabSpec spec2=tabHost.newTabSpec("Tab 2");
    spec2.setIndicator("Tab 2",getResources().getDrawable(R.drawable.icon_tab2_config));
    spec2.setContent(R.id.tab2);

使用不同的则tabspec值确定的问题对我来说。

using different TabSpec values fixed the issue for me.
