我已经创建了我的 TabLayout，当我设置为从我的主类加载的第一个屏幕时，它工作正常。我在这里按照教程：http: //joshclemm.com/blog/ ?p=136
但是，我不希望它成为加载的第一件事。
我有一个带有 的应用程序splashscreen，然后转到home没有选项卡的屏幕。它上面有一堆按钮。然后，当您单击其中一个按钮时，我想加载放置在 a 中的视图，tabgroup然后您可以单击常规选项卡。任何想法如何在Android上做这个基本的事情？
我不断收到运行时异常错误。
java.lang.RuntimeException: Unable to start activity ComponentInfo{ttj.android.ft/ttj.android.ft.Transfers}: java.lang.IllegalStateException: Did you forget to call 'public void setup(LocalActivityManager activityGroup)'
这是我的onCreate方法代码。
我有一个名为 的按钮Transfers，当它被单击时Transfers.class activity，它是一个 tablayout 应该打开但没有。活动在 android 清单中。我是菜鸟，所以我知道我可能在这里做一些非常简单的错误。
帮助将不胜感激！
public class MainActivity extends Activity {
Button Records, Transfers, Leagues;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Transfers = (Button) findViewById(R.id.bTransfers);
Transfers.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent openTransfers = new Intent(MainActivity.this,
Transfers.class);
startActivity(openTransfers);
}
});
这是我的 Android 清单
<activity
android:name=".Splash"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

</activity>
这是 logcat 崩溃时的日志。

转移活动代码
public class Transfers extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.m_transfers);
TabHost mTabHost = getTabHost();
Intent intentTeams = new Intent().setClass(this, TransfersTeams.class);
TabSpec teamsTab = mTabHost.newTabSpec("TEAMS").setIndicator("")
.setContent(intentTeams);
Intent intentSummary = new Intent().setClass(this,
TransfersSummary.class);
TabSpec summaryTab = mTabHost.newTabSpec("SUMMARY").setIndicator("")
.setContent(intentSummary);
mTabHost.addTab(teamsTab);
mTabHost.addTab(summaryTab);
mTabHost.setCurrentTab(0);
}
固定的
我的课程 TransfersTeams 和 TransfersSummary 正在扩展 TabActivity。我将其更改为 Activity，它现在可以工作了。
