突发奇想，Android实现类似于刮彩票的效果，于是完成了一个小例子，其中有不完善的地方，比如判断彩票是否中奖是以是否刮彩票3次判断的，而不是以面积来计算的。
核心部分是借鉴网上代码的，不过找不到源地址了。
实现了基本的刮奖效果，并且进行了一定的封装，拷贝其中的类即可使用。

代码如下：
ErnieActivity类：
public class ErnieActivity extends Activity{
Button erniebtn;
RelativeLayout container;
ErinieShow erinieShow;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
erniebtn=(Button) findViewById(R.id.erniebtn);
container=(RelativeLayout) findViewById(R.id.container);
erniebtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showErnie();
}
});
}
private void showErnie(){
// container
container.removeAllViews();
int level = getLevel();
erinieShow=new ErinieShow(this, level);
container.addView(erinieShow,new LayoutParams(-2,-2));
}
/**
* 获取奖励等级
* @return
*/
public int getLevel(){
//随机，看看几等奖
double d=Math.random()*100;
if(d<50){
return 0;
}
if(d<80){
return 3;
}
if(d<95){
return 2;
}
return 1;
}
@Override
protected void onDestroy() {
super.onDestroy();
}
}
ErinieShow类：
public class ErinieShow extends RelativeLayout {
Context context;
RelativeLayout rubblerBG;
RubblerShow rubblerShow;
Button getReward;
int rubblerBGId = 10001;
int getRewardId = 10002;
int level;
public ErinieShow(Context context, int level) {
super(context);
this.context = context;
this.level = level;
getElement();
setElementLP();
setElementStyle();
setElement();
}
private void getElement() {

rubblerBG.setId(rubblerBGId);

}
private void setElementLP() {
int[] resolution = PhoneUtil.getResolution(context);

resolution[0], PhoneUtil.getFitHeight(context, 125));
rubblerBG.setLayoutParams(rubblerBG_LP);
rubblerShow.setLayoutParams(rubblerBG_LP);
RelativeLayout.LayoutParams getReward_LP = new LayoutParams(-2, -2);
getReward_LP.addRule(RelativeLayout.CENTER_HORIZONTAL);
getReward_LP.addRule(RelativeLayout.BELOW,rubblerBGId);
getReward.setLayoutParams(getReward_LP);
}
private void setElementStyle() {
switch (level) {
case 0:
rubblerBG.setBackgroundResource(R.drawable.rewardlevel0);
break;
case 1:
rubblerBG.setBackgroundResource(R.drawable.rewardlevel1);
break;
case 2:
rubblerBG.setBackgroundResource(R.drawable.rewardlevel2);
break;
default:
rubblerBG.setBackgroundResource(R.drawable.rewardlevel3);
break;
}
// getReward.setBackgroundResource(R.drawable.get_award);
}
private void setElement() {
rubblerShow.beginRubbler(Color.parseColor("#d3d3d3"), 30, 10);
getReward.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if(level==0){
Toast.makeText(context, "很遗憾，此次未中奖，再接再厉吧！", Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(context, "恭喜您，获得了"+level+"等奖。", Toast.LENGTH_SHORT).show();
}
}
});
//先设置为不可点击
getReward.setClickable(false);
getReward.setText("领奖");
}
