I used java to make a gadget for android image copying, do it yourself, and have enough food and clothing.
reason
After making a picture with sketch, the exported picture is in a folder named as follows:
The Android image structure is probably like this:
res
- drawable-mdpi
- drawable-hdpi
- drawable-xhdpi
- drawable-xxhdpi
That is to say, when copying pictures, they need to be placed one by one, which is more troublesome.
as the picture shows:
code
So use java to write a jar to automatically complete.
code show as below:
package com.qefee.pj.drawablecopy;
import java.io.File;
import java.io.FileFilter;
import java.io.IOException;
public class Application {
public static void main(String[] args) {
if (args.length >= 2) {
String drawableFolderString = args[0];
File drawableFolder = new File(drawableFolderString);
String toDirString = args[1];
File toDir = new File(toDirString);
FileFilter fileFilter = new FileFilter() {
public boolean accept(File pathname) {
boolean pngFlag = pathname.getName().endsWith(".png");
boolean jpgFlag = pathname.getName().endsWith(".jpg");
return pngFlag || jpgFlag;
}
};
DrawableCopyWalker directoryWalker = new DrawableCopyWalker(fileFilter, toDir);
try {
directoryWalker.start(drawableFolder);
} catch (IOException e) {
e.printStackTrace();
}
} else {
echo("参数错误");
}
}
private static void echo(String msg) {
System.out.println(msg);
}
}
package com.qefee.pj.drawablecopy;
import org.apache.commons.io.DirectoryWalker;
import org.apache.commons.io.FileUtils;
import org.apache.commons.lang3.StringUtils;
import java.io.File;
import java.io.FileFilter;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Collection;
public class DrawableCopyWalker extends DirectoryWalker {
private File toDir;
DrawableCopyWalker(FileFilter filter, File toDir) {
super(filter, -1);
this.toDir = toDir;
}
@Override
protected void handleFile(File file, int depth, Collection results) throws IOException {
super.handleFile(file, depth, results);
String fileName = file.getName();
String mdpi = "@mdpi";
String hdpi = "@hdpi";
String xhdpi = "@xhdpi";
String xxhdpi = "@xxhdpi";
String xxxhdpi = "@xxxhdpi";
// app icon
if (fileName.contains("ic_launcher")) {
if (fileName.contains(mdpi)) {
copyImage(file, fileName, mdpi, toDir, "mipmap-mdpi");
} else if (fileName.contains(hdpi)) {
copyImage(file, fileName, hdpi, toDir, "mipmap-hdpi");
} else if (fileName.contains(xhdpi)) {
copyImage(file, fileName, xhdpi, toDir, "mipmap-xhdpi");
} else if (fileName.contains(xxhdpi)) {
copyImage(file, fileName, xxhdpi, toDir, "mipmap-xxhdpi");
} else if (fileName.contains(xxxhdpi)) {
copyImage(file, fileName, xxxhdpi, toDir, "mipmap-xxxhdpi");
} else {
System.out.println("文件未处理 : " + file.getAbsolutePath());
}
} else {
// 普通图片
if (fileName.contains(mdpi)) {
copyImage(file, fileName, mdpi, toDir, "drawable-mdpi");
} else if (fileName.contains(hdpi)) {
copyImage(file, fileName, hdpi, toDir, "drawable-hdpi");
} else if (fileName.contains(xhdpi)) {
copyImage(file, fileName, xhdpi, toDir, "drawable-xhdpi");
} else if (fileName.contains(xxhdpi)) {
copyImage(file, fileName, xxhdpi, toDir, "drawable-xxhdpi");
} else {
System.out.println("文件未处理 : " + file.getAbsolutePath());
}
}
}
private void copyImage(File file, String fileName, String mdpi, File toDir, String child) throws IOException {
File mdpiDir = new File(toDir, child);
String newFileName = StringUtils.remove(fileName, mdpi);
File newFile = new File(mdpiDir, newFileName);
FileUtils.copyFile(file, newFile);
}
void start(File startDirectory) throws IOException {
ArrayList<File> dirs = new ArrayList<File>();
this.walk(startDirectory, dirs);
}
}

Instructions
After exporting the jar, execute it on the command line
Among them, fromFolder
is the picture folder, toFolder
pointing to the res folder of Android
java -jar copyImage.jar fromFolder toFolder(res)
