我使用下面的代码在Api-11下创建ActionBar，它工作正常，但是当我想在另一个Api-11项目中使用它时，强制关闭发生在我的设备上运行应用程序时。哪里有问题？ActionBar问题
当我制作一个新项目并编译它并在Android设备上运行应用程序时，它工作正常！
package a.pkg;
import android.app.ActionBar;

/** Called when the activity is first created. */
@Override

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",

}
});

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