我想在我的新画廊中动态添加和删除图像。我正在将图像转换为字节数组（位图）并发送到另一个应该是我的新画廊的活动。当我使用一个图像时，这很好用。但是当我将另一个图像转换为 byteArray 并将第二个图像覆盖第一个图像发送到我的新图库中的另一个活动。如何添加和删除两张图片和更多不同的图片。图片尺寸小））））非常感谢功能回复。
有我要发送图片的代码
private void saveFirstSelectedImageIdPreferences(String key, int position) {
firstSelectionPositionId = position;
sp = PreferenceManager.getDefaultSharedPreferences(this);
Editor edit = sp.edit();
edit.putInt(key, firstSelectionPositionId);
Log.d(MY_LOG,"///// saving first selected image id/////////////////////"
+ firstSelectionPositionId);
edit.commit();
//decode picture into byte array
Bitmap btm = BitmapFactory.decodeResource(getResources(), R.drawable.sport_0);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
btm.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte [] byteArray = stream.toByteArray();
//sending picture into favorite activity
Intent intent = new Intent(this,Favorites.class);
intent.putExtra("sport_0", byteArray);
startActivity(intent);
Log.d(MY_LOG,"convert first item to bytes");
Toast.makeText(this, "Picture add to favorite", Toast.LENGTH_SHORT).show();
}
在这行代码中byte[] byteArray = {(byte)R.drawable.sport_0} 我可以只添加一个图像，就是这样。如何做而不是单击按钮单击添加和按钮取消单击删除图片录制图片。也许你知道解决这个问题的更好方法。请帮我解决这个问题。再次感谢您的回复。
