Android适配生成对应的values文件
Android适配生成对应的values文件(如：values-1080x1920)
github查看 https://github.com/itrenjunhua/screen
使用如下Java代码自动生成多个values文件夹以及对应的lay-x.xml、lay-y.xml文件

// 定义需要适配的分辨率

根据lay-x.xml、lay-y.xml文件生成 dimens_x.xml、dimens_y.xml 文件，编译和运行如下代码
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.PrintWriter;

sbForX.append("@dimen/x" + (i * 2) + " \n");
}
sbForX.append(" ");
StringBuffer sbForY = new StringBuffer();
sbForY.append("\n");
sbForY.append("");
for (int i = 1; i <= yValueCount; i++) {
sbForY.append("@dimen/y" + (i * 2) + " \n");
}
sbForY.append(" ");
File fileDir = new File("./values" + File.separator);
fileDir.mkdir();

pw.close();
PrintWriter py = new PrintWriter(new FileOutputStream(yCountFile));
py.print(sbForY.toString());
py.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
int xMaxValue = 600;

try {
