我正在屏幕底部创建一个类似iphone的菜单栏。它被设计为标签页，每当我调用它时，它就会卡在第一行
tabHost.addTab(createTab(Settings.class, "Settings", "Settings",
R.drawable.settingsicon));
页面Settings.java正常工作，我检查了我的清单，看看我的所有活动是否都添加到那里。我无法弄清楚为什么我一直收到这个错误。我尝试使用try / catch块，但它不允许我，因为它说它永远不会有错误，所以我无法看到我的LogCat确切的错误。这是我的代码。 TabPage.java
public class TabPage扩展了TabActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_layout);
final TabHost tabHost = (TabHost) getTabHost();
tabHost.addTab(createTab(Settings.class, "Settings", "Settings",
R.drawable.settingsicon));
tabHost.addTab(createTab(ImTracking.class, "I\'m Tracking",
"I\'m Tracking", R.drawable.mapbutton));
tabHost.addTab(createTab(TrackingMe.class, "Tracking Me",
"Tracking Me", R.drawable.friends));
tabHost.addTab(createTab(ImTracking.class,"I\'m Tracking","I\'m Tracking",R.drawable.like));
tabHost.addTab(createTab(ImTracking.class,"I\'m Tracking","I\'m Tracking",R.drawable.help));
tabHost.setCurrentTab(0);
tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 85;
tabHost.getTabWidget().getChildAt(1).getLayoutParams().width = 85;
tabHost.getTabWidget().getChildAt(2).getLayoutParams().width = 85;
tabHost.getTabWidget().getChildAt(3).getLayoutParams().width = 85;
tabHost.getTabWidget().getChildAt(4).getLayoutParams().width = 85;
}
private TabSpec createTab(final Class<?> intentClass, final String tag,
final String title, final int drawable)
{
final Intent intent = new Intent().setClass(this, intentClass);
final View tab = LayoutInflater.from(getTabHost().getContext()).
inflate(R.layout.tab, null);
((TextView)tab.findViewById(R.id.tab_text)).setText(title);
((ImageView)tab.findViewById(R.id.tab_icon)).setImageResource(drawable);
return getTabHost().newTabSpec(tag).setIndicator(tab).setContent(intent);
}
}

我的设置页面在调用时正常工作，此处显示是否有我忽略的内容。 Settings.java
public class Settings extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.settings);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
R.layout.custom_title_4);
Button deleteAccount = (Button) findViewById(R.id.btnDeleteAccount);
deleteAccount.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
new AlertDialog.Builder(Settings.this)
// fix this later
.setTitle(
getResources().getString(
R.string.deleteaccountquestion))
.setMessage(
getResources().getString(
R.string.selectingyeswill))
.setPositiveButton("No", null)
.setNegativeButton("Yes",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0,
int arg1) {
SharedPreferences prefs = getSharedPreferences(
"Settings", 0);
SharedPreferences.Editor editor = prefs
.edit();
editor.putBoolean(
"ImTrackingDontRemind", false);
editor.putBoolean("ACTIVATED", false);
editor.putString("ID", "");
editor.commit();
}
}).show();
}
});
Button MORETESTS=(Button) findViewById(R.id.btnHistory);
MORETESTS.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent tabpage=new Intent("com.cellphone.TABPAGE");
startActivity(tabpage);
}
});
TextView myname=(TextView) findViewById(R.id.tVName);
SharedPreferences prefs = getSharedPreferences("Settings", 0);
final String me = prefs.getString("MyName", "");
myname.setText(me);
Button reEnableHelp = (Button) findViewById(R.id.btnRenableHelpScreen);
reEnableHelp.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO
// Auto-generated
// method stub
SharedPreferences prefs = getSharedPreferences("Settings", 0);
SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean("ImTrackingDontRemind", false);
editor.commit();
};
});
}
}
谢谢！
