活不多說 上代碼:

Observable.create(new ObservableOnSubscribe() {

@Override

public void subscribe(ObservableEmitter e) throws Exception {

//通過gilde下載得到file文件,這里需要注意android.permission.INTERNET權限

e.onNext(Glide.with(mContext)

.load(imagePathList.get(currentViewPosition).getPath())

.downloadOnly(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)

.get());

e.onComplete();

}

}).subscribeOn(Schedulers.io())

.observeOn(Schedulers.newThread())

.subscribe(new Consumer() {

@Override

public void accept(File file) throws Exception {

//獲取到下載得到的圖片，進行本地保存

File pictureFolder = Environment.getExternalStorageDirectory();

//第二個參數為你想要保存的目錄名稱

File appDir = new File(pictureFolder, "your_picture_save_path");

if (!appDir.exists()) {

appDir.mkdirs();

}

String fileName = System.currentTimeMillis() + ".jpg";

File destFile = new File(appDir, fileName);

//把gilde下載得到圖片復制到定義好的目錄中去

copy(file, destFile);

// 最后通知圖庫更新

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,

Uri.fromFile(new File(destFile.getPath()))));

}

});

帶個復制文件的代碼:

/**

* 復制文件

*

* @param source 輸入文件

* @param target 輸出文件

*/

public void copy(File source, File target) {

FileInputStream fileInputStream = null;

FileOutputStream fileOutputStream = null;

try {

fileInputStream = new FileInputStream(source);

fileOutputStream = new FileOutputStream(target);

byte[] buffer = new byte[1024];

while (fileInputStream.read(buffer) > 0) {

fileOutputStream.write(buffer);

}

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

fileInputStream.close();

fileOutputStream.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

注意要加權限:

最后需要注意的下載保存需要讀寫權限，6.0以后需手動申請權限

android.permission.WRITE_EXTERNAL_STORAGE

android.permission.READ_EXTERNAL_STORAGE
