代码如下：

public class TimeDialog extends Dialog {

    private ImageButton quit;

    private TextView calendar;

    private ImageButton close;

    private FixedGridView times;

    private Button btn;

    public TimeDialog(Context context) {

        super(context, R.style.ShadowDialog);

    }

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.dialog_time);

        Window window = getWindow();

        window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

        window.setWindowAnimations(R.style.dialogAnimBottom); 

        setCanceledOnTouchOutside(false);

        quit = (ImageButton) findViewById(R.id.time_quit);

        calendar = (TextView) findViewById(R.id.time_calendar);

        close = (ImageButton) findViewById(R.id.time_close);

        times = (FixedGridView) findViewById(R.id.time_times);

        btn = (Button) findViewById(R.id.time_btn);

        data = new ArrayList< >();

        adapter = new TimeAdapter(data);

        times.setAdapter(adapter);

    }

}

比如：

LinearLayout layout = (LinearLayout) findViewById(R.id.layout);

ImageButton b1 = (ImageButton)layout.findViewById(R.id.b1);
