Q1: 怎么用java做动画
重写paint方法Java风车动画代码，来实现将自己定义Java风车动画代码的图片绘制到组件中Java风车动画代码，然后启动一个线程来控制paint方法。 示例Java风车动画代码： ××××××××××××××××××××××××××× import javax.swing.*; import java.awt.*;class MyPanel extends JPanel implements Runnable {private Image img;private int i=0;private int j=0;public MyPanel(){img=new ImageIcon("1.png").getImage();}public void paint(Graphics g){g.drawImage(img,0,0,60,104,i*60,j*104,i*60+60,j*104+104,this);}public void run(){while(true){while(j {while(i {try{Thread.sleep(300);}catch(Exception e){}this.repaint();i++;}j++;i=0;}i=0;j=0;}} }public class test extends JFrame {private MyPanel p;public test(){p=new MyPanel();this.add(p,BorderLayout.CENTER);this.setBounds(300,200,300,300);this.setTitle("人物行走图");new Thread(p).start();this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}public static void main(String args[]){new test();} }××××××××××××××××××××××× 将以上源码保存为：test.java，编译，然后下载下面的图片 将下载的图片改名为1.png" target="_blank"
,然后将其和编译后生成的class文件放在同一文件夹下，然后运行就可以Java风车动画代码了·～～
Q2: java实现风车旋转，为嘛我的画出来时一个圆在旋转
画之前加上g.clearRect(0, 0, getWidth(), getHeight());
不然你上一次画的还会呈现出来
这样呢，就会闪烁，需要使用双缓冲来解决了。
需要请追问。

Q4: 怎样使用内存双缓冲技术消除屏幕闪烁？
CDC BufferDC;
CBitmap BufferImage;
BufferDC.CreateCompatibleDC(dc);
BufferImage.CreateCompatibleBitmap(dc,rcClient.Width(),rcClient.Height());
BufferDC.SelectObject(BufferImage); //创建好Java风车动画代码的image就是新的背景图Java风车动画代码，Java风车动画代码你可以往上面继续画东西。
这是MFC的例子，Java风车动画代码你自己转到API吧，试试看吧。
Q5: 如何设置ImageButton按键按下去后的 特效
android默认的Imagebutton按下去之后没有一点变化，实在让人受不了。这次在重新写摄像头相关的demo时，特意学习了这方面的内容。
第一种方法：
可以用美图秀秀将同一个图片做成不同的灰度/色调效果，保存成同样大小的图片，然后利用htt p:/ /blo g.c sd n.ne t/yanzi1 22 56 27/article/details/7 81 43 92这里设置成点击显示不同色调灰度的同一副图片。
第二种方法：
还是同样的思路，只不过不是在xml文件里，而是在java程序里更改点击显示不同图片，如下：
imageButton.setOnTouchListener(new OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN){
//更改为按下时的背景图片
v.setBackgroundResource(R.drawable.pressed);
}else if(event.getAction() == MotionEvent.ACTION_UP){
//改为抬起时的图片
v.setBackgroundResource(R.drawable.released);
}
return false;
}
});
第三种方法：
这也是我采用的方法。前两种方法在按键多的情况下用起来很不方便，当然不排除个别情况下就需要显示不同的图片。这里用颜色矩阵的方法，只需一张照片，就可以实现效果。且这个效果可以往任何一个ImageButton上绑定。代码如下：
/*为了使图片按钮按下和弹起状态不同，采用过滤颜色的方法.按下的时候让图片颜色变淡*/
public class MyOnTouchListener implements OnTouchListener{
public final float[] BT_SELECTED=new float[]
{ 2, 0, 0, 0, 2,
0, 2, 0, 0, 2,
0, 0, 2, 0, 2,
0, 0, 0, 1, 0 };
public final float[] BT_NOT_SELECTED=new float[]
{ 1, 0, 0, 0, 0,
0, 1, 0, 0, 0,
0, 0, 1, 0, 0,
0, 0, 0, 1, 0 };
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if(event.getAction() == MotionEvent.ACTION_DOWN){
v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_SELECTED));
v.setBackgroundDrawable(v.getBackground());
}
else if(event.getAction() == MotionEvent.ACTION_UP){
v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_NOT_SELECTED));
v.setBackgroundDrawable(v.getBackground());
}
return false;
}
}
可以用我htt p:/ /blog.csdn.net/yanz i1 22 56 27/artic le/details/8 57 775 6这里的图片测试下，ImageButton按下后会有类似风车旋转的动画特效。
