@Test
public void shouldWriteToParcelAndReconstruct() {
 Bitmap bitmapOriginal;
 int originalWidth = 10;
 int originalHeight = 10;
 bitmapOriginal = Bitmap.createBitmap(originalWidth, originalHeight, Bitmap.Config.ARGB_8888);
 Parcel parcel = Parcel.obtain();
 bitmapOriginal.writeToParcel(parcel, 0);
 parcel.setDataPosition(0);
 Bitmap bitmapReconstructed = Bitmap.CREATOR.createFromParcel(parcel);
 // get reconstructed properties
 int reconstructedHeight = bitmapReconstructed.getHeight();
 int reconstructedWidth = bitmapReconstructed.getWidth();
 //compare bitmap properties
 assertThat(originalHeight).isEqualTo(reconstructedHeight);
 assertThat(originalWidth).isEqualTo(reconstructedWidth);
 assertThat(bitmapOriginal.getConfig()).isEqualTo(bitmapReconstructed.getConfig());
 int[] pixelsOriginal = new int[originalWidth * originalHeight];
 bitmapOriginal.getPixels(pixelsOriginal, 0, originalWidth, 0, 0, originalWidth, originalHeight);
 int[] pixelsReconstructed = new int[reconstructedWidth * reconstructedHeight];
 bitmapReconstructed.getPixels(pixelsReconstructed, 0, reconstructedWidth, 0, 0,
   reconstructedWidth, reconstructedHeight);
 assertThat(Arrays.equals(pixelsOriginal, pixelsReconstructed)).isTrue();
}

@Override
protected void doWrite(Bitmap value, int flags) {
  value.writeToParcel(parcel, flags);
}

//Store
Parcel parcel = Parcel.obtain();
Bitmap sourceBitmap = Bitmap.createBitmap(200, 400, Config.ARGB_8888);
sourceBitmap.writeToParcel(parcel, 0);

//Retrieve
parcel.setDataPosition(0);
Bitmap destinationBitmap = Bitmap.CREATOR.createFromParcel(parcel);

代码示例来源:origin: fennifith/Status

if (largeIcon != null) {
  dest.writeByte((byte) 1);
  largeIcon.writeToParcel(dest, flags);
} else dest.writeByte((byte) 0);

代码示例来源:origin: stackoverflow.com

// Setup to get a mutable bitmap less than 40 Kbytes
 String path = "someSmallImage.jpg";
 Bitmap bm0 = BitmapFactory.decodeFile(path);
 // Need it mutable to change height
 Bitmap bm1 = bm0.copy(bm0.getConfig(), true);
 // Chop it to get a size less than 40K
 bm1.setHeight(bm1.getHeight() / 32);
 // Now we have a BitMap with size < 40K for the test
 Bitmap bm2 = bm1.copy(bm0.getConfig(), true);
 // What's the parcel size?
 Parcel p1 = Parcel.obtain();
 bm2.writeToParcel(p1, 0);
 // Expect byteCount and allocatedByteCount to be the same
 Log.i("Demo", String.format("byteCount=%d allocatedByteCount=%d parcelDataSize=%d",
     bm2.getByteCount(), bm2.getAllocationByteCount(), p1.dataSize()));
 // Resize to make byteCount and allocatedByteCount different
 bm2.setHeight(bm2.getHeight() / 4);
 // What's the parcel size?
 Parcel p2 = Parcel.obtain();
 bm2.writeToParcel(p2, 0);
 // Show that byteCount determines size of data written to parcel
 Log.i("Demo", String.format("byteCount=%d allocatedByteCount=%d parcelDataSize=%d",
     bm2.getByteCount(), bm2.getAllocationByteCount(), p2.dataSize()));
 p1.recycle();
 p2.recycle();
