推荐答案

看哪：

public class MyActivity extends Activity {

    // LayoutInflater inflater = (LayoutInflater) context 
    //         .getSystemService(Context.LAYOUT_INFLATER_SERVICE); // NOT CORRECT
    LayoutInflater inflater; // correct

    @Override
    protected void onCreate(Bundle saved) {
        super.onCreate(saved);
        inflater = (LayoutInflater) context 
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE); // correct
    }
}
