setContentView(R.layout.main_activity);
Bundle args = getIntent().getExtras();
selectedProfileName = args.getString("key_name");
InitializeActionBar();
}
public void InitializeActionBar() {
actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab tabBodyPart = actionBar.newTab();

复制面食错误。
你有:
tabBodyPart.setText("General Symptoms");
tabBodyPart.setTabListener(MainActivity.this);
你想:
tabGeneralSymptoms.setText("General Symptoms");
tabGeneralSymptoms.setTabListener(MainActivity.this);

您正在使用v4库不支持的操作栏,而是使用v7。使用ActionBarActivty
扩展FragmentActivity
。
