我想在gridview上绘制字母（基本上是作为led板）。我试图从用户获取输入字符串并在gridview中绘制该字符串，如下所示。 gridview大小由两个6x5板固定。我需要以这样的方式绘制该字符串，使得框架看起来从右向左移动（基本上每2秒间隔刷新一次布局）。我无法理解如何通过输入字符串在gridview单元格上绘制这些字母。任何类型的引用和链接也适用于我。
在下次更新时，列应该向左移动一列，在这种情况下，我们应该能够看到第一个字母的4/5和完整的第二个字母，第三个字母才会从右侧开始输入..

也许在2秒的间隔内做类似的事情：
int i = currentCharacter;
//code for left char
switch(str.charAt(i)){
case "A":
//Code for the letter A
break;
case "B":
//Code for the letter B
break;
...
}
//code for right char
switch(str.charAt(i+1)){
case "A":
//Code for the letter A
break;
case "B":
//Code for the letter B
break;
...
}
currentCharacter++;
你可以给出彩色立方体ID，只需定义颜色即可。所以例如字母'S'就像：
cube1.setBackgroundColor(Color.RED);
cube2.setBackgroundColor(Color.GREEN);
cube3.setBackgroundColor(Color.GREEN);
cube4.setBackgroundColor(Color.GREEN);
cube5.setBackgroundColor(Color.RED);
cube6.setBackgroundColor(Color.RED);
cube7.setBackgroundColor(Color.GREEN);
cube8.setBackgroundColor(Color.RED);
cube9.setBackgroundColor(Color.RED);
cube10.setBackgroundColor(Color.RED);
//and so one ...
如果网格是这样的：
01 02 03 04 05
06 07 08 09 10
11 12 13 14 15 ...
这只是一个想法，但它可以帮助你：D

嘿，我得到了上面的解决方案 - 我自己开发了一个类，它具有一个以字符作为输入并以6 * 6矩阵和放大器返回其显示模式的功能。长度字段用于确保显示的宽度。使用此jar为整个字符串创建一个2-d数组，并使用一端的屏幕大小窗口遍历该数组。这是该类的代码：
public class TextPat {
