Android自定义有动画效果，用于选择的Layout

public class SelectLayout extends LinearLayout {

    private AnimationSet mInAnime;
    private AnimationSet mOutAnime;
    private Animation mAlphaAnime;
    private View mCheckView;
    private View[] mViewArray;
    public SelectLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO 鑷姩鐢熸垚鐨勬瀯閫犲嚱鏁板瓨鏍?
    }
    
    public void iniSelectLayout(){
        
    
        iniAnimation();
        mViewArray=new View[getChildCount()];
        for(int i=0;i<getChildCount();i++){
            mViewArray[i]=getChildAt(i);
            if(i>0)
                mViewArray[i].startAnimation(mAlphaAnime);
        }
        
        mCheckView=mViewArray[0];
        mCheckView.startAnimation(mInAnime);
        
        MyOnClickListener tmp=new MyOnClickListener();
        for(View item:mViewArray)
            item.setOnClickListener(tmp);
        
        
        
    }
    
    
    private void iniAnimation(){
        mInAnime=new AnimationSet(false);
        ScaleAnimation tmp=new ScaleAnimation(1, 1.2f, 1, 1.2f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        tmp.setDuration(300);
        AlphaAnimation tmp2=new AlphaAnimation(0.7f, 1);
        tmp2.setDuration(300);
        mInAnime.addAnimation(tmp);
        mInAnime.addAnimation(tmp2);
        mInAnime.setFillAfter(true);
        
        tmp=new ScaleAnimation(1.2f, 1, 1.2f, 1, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        tmp.setDuration(300);
        tmp2=new AlphaAnimation(1, 0.7f);
        tmp2.setDuration(300);
        mOutAnime=new AnimationSet(false);
        mOutAnime.addAnimation(tmp);
        mOutAnime.addAnimation(tmp2);
        mOutAnime.setFillAfter(true);
        
        mAlphaAnime=new AlphaAnimation(0.7f,0.7f);
        mAlphaAnime.setFillAfter(true);
    }
    
    public View getSelectView(){
        return mCheckView;
    }
    
    private class MyOnClickListener implements OnClickListener{

        @Override
        public void onClick(View v) {
            // TODO 鑷姩鐢熸垚鐨勬柟娉曞瓨鏍?
            if(!v.equals(mCheckView)){
                
            for(int i=0;i<mViewArray.length;i++){
                if(!mViewArray[i].equals(v)&&!mViewArray[i].equals(mCheckView))
                    mViewArray[i].startAnimation(mAlphaAnime);
            }
            v.startAnimation(mInAnime);
            mCheckView.startAnimation(mOutAnime);
            
        
            mCheckView=v;
            
            
            }
        }
        
    }

继承自LinearLayout，在xml里当LinearLayout用就行了，调用iniSelectLayout后会有类似RadioGroup的功能，被选中的子View会放大，没被选中的是半透明。注意如果子View的背景是jpg的话会出现闪烁，png不会。
