问题描述
我正在尝试压缩图像文件列表,并在压缩后将其存储在缓存目录中。这里的问题是某些图像文件未正确压缩。它提供了一些半压缩的图像。请帮助我解决此问题。
请检查下面的半压缩图像,

这是我的代码,
val latch = CountDownLatch(uriList.size)
val executorService: ExecutorService = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors())
val callables: MutableList<Callable<String>> = java.util.ArrayList()
for (i in 0 until uriList.size) {
val uri: Uri = uriList[i]
callables.add(Callable<String> {
publishProgress(i.toString())
val imageCompresser = ImageCompresser(App.context)
val tempString1 = imageCompresser.compressImage(uri.path!!)
latch.countDown();
tempString1
})
}
var resultList: List<Future<String>>? = null;
try {
resultList = executorService.invokeAll(callables);
} catch (e: InterruptedException) {
e.printstacktrace();
}
try {
latch.await();
} catch (E: InterruptedException) {
// handle
}
try {
for (future in resultList!!) {
mImagePathsList.add(future.get().toString())
}
} catch (ce: CancellationException) {
ce.printstacktrace();
} catch (ee: ExecutionException) {
ee.printstacktrace();
} catch (ie: InterruptedException) {
Thread.currentThread().interrupt();
}
executorService.shutdown()
while (!executorService.isTerminated) {
}
executorService.shutdown()
