Answer 1

1.Permissions清單文件

<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 

2.Glide下載圖片作爲位圖

Glide.with(mContext) 
     .load("YOUR_URL") 
     .asBitmap() 
     .into(new SimpleTarget<Bitmap>(100,100) { 
      @Override 
      public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) { 
        saveImage(resource); 
      } 
     }); 

3.保存位圖到你的記憶

private String saveImage(Bitmap image) { 
    String savedImagePath = null; 

    String imageFileName = "JPEG_" + "FILE_NAME" + ".jpg"; 
    File storageDir = new File(   Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) 
         + "/YOUR_FOLDER_NAME"); 
    boolean success = true; 
    if (!storageDir.exists()) { 
    success = storageDir.mkdirs(); 
    } 
    if (success) { 
     File imageFile = new File(storageDir, imageFileName); 
     savedImagePath = imageFile.getAbsolutePath(); 
     try { 
      OutputStream fOut = new FileOutputStream(imageFile); 
      image.compress(Bitmap.CompressFormat.JPEG, 100, fOut); 
      fOut.close(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

     // Add the image to the system gallery 
     galleryAddPic(savedImagePath); 
     Toast.makeText(mContext, "IMAGE SAVED", Toast.LENGTH_LONG).show(); 
    } 
    return savedImagePath; 
} 

private void galleryAddPic(String imagePath) { 
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE); 
    File f = new File(imagePath); 
    Uri contentUri = Uri.fromFile(f); 
    mediaScanIntent.setData(contentUri); 
    sendBroadcast(mediaScanIntent); 
}
