使用方法
使用工具類 ImgCompressUtils
使用方法
ImgCompressUtils.getInstance().compress(context, 300, photoPathList, files, new ImgCompressUtils.CompressFinishCallBack() {
@Override
public void compressStart(String msg) {
LogUtils.i(msg);
context.showMsg(msg);

LogUtils.i("壓縮完圖片集合為:");
context.showMsg("圖片壓縮完成");

for (File temp : files) {
LogUtils.i("圖片大小:" + temp.length() / 1000 + "K");
compressFiles.put(temp.getAbsolutePath(), temp);
}
context.showMsg("圖片開始上傳");
LogUtils.e("圖片開始上傳");
}
//上傳資料
}

@Override
public void compressError(String msg) {
LogUtils.i(msg);
context.showMsg(msg);
}
});

//上傳資料成功回撥(刪除壓縮的圖片)
方式一:
ImgCompressUtils.getInstance().delFile(compressFiles, new ImgCompressUtils.DelComPressCallBack() {
@Override
public void success() {
LogUtils.i("刪除成功");
}

@Override
public void fail() {
LogUtils.i("刪除失敗");
}
