我需要在ImageView的边缘创建一个alpha渐变.最好只使用XML.

例如图像

更新jrk7-openjdk和jre7-openjdk字体后,不显示Idea.重新安装包openjdk和想法没有帮助.

我正在尝试创建一种幻灯片放映.为此,我需要在每个动画结束时通过更改图像来使循环成为动画.但无论出于何种原因,每个动画都会发生两次相同的事件

public cPhotoSlide(Activity _activity, DBHelper _helper, int idMenu, cItemViewer _ItemViewer){
    activity        = _activity;
    helper          = _helper;
    ImageManager    = helper.ImageManager;
    ItemViewer      = _ItemViewer;
    cursor          = 0;        
    itemIds         = ChildsItemsToTable(idMenu);
    MainLayout      = (RelativeLayout) activity.findViewById(R.id.fon);
    SliderObj       = activity.getLayoutInflater().inflate(R.layout.photo_slide, MainLayout, true);
    SlideImage      = (ImageView) SliderObj.findViewById(R.id.slide_image);
    SlideImage.setImageBitmap(ImageManager.loadImage(activity.getApplicationContext(),itemIds.get(cursor)));

    animationSlide  = (AnimationSet) AnimationUtils.loadAnimation(activity.getApplicationContext(), R.anim.slide);

    animationSlide.getAnimations().get(1).setAnimationListener(
            new AnimationListener() {
                public void onAnimationStart(Animation animation) {}
                public void onAnimationRepeat(Animation animation) {}
                public void onAnimationEnd(Animation animation) {
                    Log.d(LOG_TAG,"Cursor = "+cursor+"/"+itemIds.size());
                    if (cursor >= itemIds.size()-1) {
                        cursor = 0;
                    } else { …

我需要构建一个涉及OpenCV的项目.它会很棒,但由于某种原因,库不会进入java.library.path库.当我尝试使用库运行代码时,我收到此错误:

*java.lang.UnsatisfiedLinkError:java.library.path中没有jniopencv_highgui*

我正在尝试使用IGE解密AES-256。但我不知道如何使用256位密钥。

在代码键 - 字节[]与长度 == 32; 四。长度 == 32; 块大小 == 16

Cipher cipher = Cipher.getInstance("AES/ECB/NoPadding");
cipher.init(Cipher.DECRYPT_MODE, new SecretKeySpec(key, "AES"));

Xprev = java.util.Arrays.copyOfRange(IV, 0, BlockSize);
Yprev = java.util.Arrays.copyOfRange(IV, BlockSize, IV.length);

Decripted = new byte[0];

for (int i = 0; i < Message.length; i += BlockSize) { 
    Y = java.util.Arrays.copyOfRange(Message, i, i+BlockSize); 
    X = XOR(cipher.doFinal(XOR(Y,Xprev)), Yprev);
    Xprev = X;
    Yprev = Y;

    Decripted = sumBytes(Decripted, X);
}
