import android.support.v7.app.ActionBarActivity; 
import android.app.Activity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.widget.Toast; 

    public class MainActivity extends Activity { 

    @Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
     // action with ID action_refresh was selected 
     case R.id.action_refresh: 
      Toast.makeText(this, "Refresh selected", Toast.LENGTH_SHORT) 
       .show(); 
      break; 
     // action with ID action_settings was selected 
     case R.id.action_settings: 
      Toast.makeText(this, "Settings selected", Toast.LENGTH_SHORT) 
       .show(); 
      break; 
     default: 
      break; 
     } 

     return true; 
} 
    }

这里是你的问题的一个快速的解决方案.....你可以申请你想在你的应用程序，你也不管主题可以简单地通过添加下面的上创建方法这2行这样的代码显示您的动作条： -

setContentView(R.layout.activity_main); 
    ActionBar actionBar = getSupportActionBar(); 
     actionBar.show();
