我有一個262144(512 * 512)的一個維像素int[] pixelsArray陣列taht我要轉換爲Bitmap並在Android應用顯示它,所以我把轉換像素陣列中的位圖的Android

bitmap = Bitmap.createBitmap(512, 512, Bitmap.Config.ARGB_8888); 
    bitmap.setPixels(pixelsArray, 0, 512, 0, 0, 512, 512); 

I get this message 

java.lang.IllegalArgumentException: bitmap size exceeds 32bits

這裏是工作的答案:

bitmap = Bitmap.createBitmap(512, 512, Bitmap.Config.ARGB_8888); 
byte[] byteArray = new String(pixelsArray).getBytes("UTF-8"); 
BitmapFactory.Options thumbOpts = new BitmapFactory.Options(); 
thumbOpts.inSampleSize = 4; 
bitmap = BitmapFactory.decodeByteArray(byteArray, 0, pixelsArray.length, thumbOpts);
