我知道这个问题已经发布了很多次，但即使我尝试了很多来自 Stack Overflow 的解决方案，我仍然无法解决。
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import com.example.project.myapplication.API.InfoAPI;
import com.example.project.myapplication.Adapter.TabsFragmentPagerAdapter;
public class Edit extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private ActionBar actionBar;
private TabsFragmentPagerAdapter tabsAdapter;
private String[] activities = new String[]{"Information","Work Force","Work Details"};
ListView listViewEdit;
InfoAPI sqlcon;
private MyDatabaseHelper dbHelper;
private SQLiteDatabase database;
private SimpleCursorAdapter dataAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit);
viewPager = (ViewPager) findViewById(R.id.viewPager);
tabsAdapter = new TabsFragmentPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(tabsAdapter);
actionBar = (ActionBarActivity)getApplicationContext().getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
for(int i=0; i<3; i++){
actionBar.addTab(actionBar.newTab().setText(activities[i]).setTabListener(this));
}
错误在这一行 actionBar = (ActionBarActivity)getApplicationContext().getSupportActionBar();
错误
Error:(48, 63) error: cannot find symbol method getSupportActionBar()
Error:(48, 21) error: incompatible types: ActionBarActivity cannot be converted to ActionBar
最佳答案
让 Edit 扩展 AppCompatActivity 而不是 FragmentActivity。 AppCompatActivity 扩展了 FragmentActivity 并添加了对 ActionBar 的支持。您可以阅读更多 here
