ActionBar问题

Question

我使用下面的代码在Api-11下创建ActionBar，它工作得很好，但当我想在另一个Api-11项目中使用它时，当我在我的设备上运行应用程序时，会发生强制关闭。问题出在哪里？

当我创建一个新的项目，编译它并在android设备上运行应用程序时，它工作得很好！

package a.pkg;
import android.app.ActionBar;
import android.app.Activity;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageButton;
import android.widget.Toast;

public class ActionBarActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ActionBar actionBar=getActionBar();

actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#fc0606")));

LayoutInflater mInflater = LayoutInflater.from(this);

View mCustomView = mInflater.inflate(R.layout.custom_actionbar, null);
//TextView mTitleTextView = (TextView) mCustomView.findViewById(R.id.title_text);
//mTitleTextView.setText("My Own Title");

final ImageButton imageButton1 = (ImageButton) mCustomView
        .findViewById(R.id.ImageButton1);
imageButton1.setOnClickListener(new View.OnClickListener() {


    public void onClick(View arg0) {
        // TODO Auto-generated method stub

        Toast.makeText(getApplicationContext(), "1",
                Toast.LENGTH_LONG).show();
    }
});

final ImageButton imageButton2 = (ImageButton) mCustomView
.findViewById(R.id.ImageButton2);
imageButton2.setOnClickListener(new View.OnClickListener() {

public void onClick(View arg0) {
// TODO Auto-generated method stub



Toast.makeText(getApplicationContext(), "2",
        Toast.LENGTH_LONG).show();
}
});

final ImageButton imageButton3 = (ImageButton) mCustomView
.findViewById(R.id.ImageButton3);
imageButton3.setOnClickListener(new View.OnClickListener() {

public void onClick(View arg0) {
// TODO Auto-generated method stub



Toast.makeText(getApplicationContext(), "3",
        Toast.LENGTH_LONG).show();

}
});


actionBar.setCustomView(mCustomView);
actionBar.setDisplayShowCustomEnabled(true);

    }
}

我发现了这个问题，我必须在清单中手动将代码从这个更改为这个。eclipse无法自动将最小Api从8更改为11。
