问题描述

我正在使用LWUIT进行J2ME Aplication，现在我必须创建一个具有2x2矩阵的四个图像按钮的表单.我确实使用GridLayout但如何使用LWUIT工具包根据Mobile的屏幕尺寸来调整图像按钮的大小?我也想知道如何在J2ME中使用Tooltip的概念，因为它在J2ME中不可用?

推荐答案

使其相对:获取屏幕分辨率并组成按钮的尺寸要符合该尺寸.

make it relative: get the screen resolution and make up the buttons size according to that.

// logic code - not usable!
ScreenWidth wide = 200;
button.setSize((int)(wide*0.2), (int)(wide*0.2)); // cast the double to int | Button will be 20% of screen width
