Android之制作漂亮的缓存界面

先贴上两张图展示界面：

上面的字体会动态显示，这种效果在我们启动一个应用程序时，经常使用

代码如下：
UIDemoActivity的代码：
[java]
public class UIDemoActivity extends Activity {
    /** Called when the activity is first created. */
    private Animation mAnimation;
    private int marginTop;
    private List<ImageView> mimageView;
    private LinearLayout mLinearLayout;
    private int[] imageId = {R.drawable.l, R.drawable.a, R.drawable.o, R.drawable.d,
            R.drawable.i, R.drawable.n, R.drawable.g};
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        //设置全屏
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
        //设置无标题
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        //获取屏幕的尺寸信息
        DisplayMetrics dm=this.getResources().getDisplayMetrics();
        marginTop=dm.heightPixels-100;

        //载入动画
        mAnimation=AnimationUtils.loadAnimation(this, R.anim.cache);

        mLinearLayout=new LinearLayout(this);
        mLinearLayout.setBackgroundResource(R.drawable.background);

        mimageView=new ArrayList<ImageView>();

        imageInit(mLinearLayout);
        this.setContentView(mLinearLayout);
        startAnimation();
    }


    private void imageInit(LinearLayout layout)
    {
        layout.setGravity(Gravity.CENTER_HORIZONTAL);
        //layout.setOrientation(LinearLayout.VERTICAL);

        //定义两个布局参数
        LinearLayout.LayoutParams param1=new LinearLayout.LayoutParams(40,40);
        param1.setMargins(0,marginTop, 0, 0);

        LinearLayout.LayoutParams param2=new LinearLayout.LayoutParams(40,40);
        param2.setMargins(0,marginTop, 0, 0);

        ImageView l = new ImageView(this);
        //应用LayoutParam
        l.setLayoutParams(param1);
        layout.addView(l);
        mimageView.add(l);

        ImageView o = new ImageView(this);
        o.setLayoutParams(param2);
        layout.addView(o);
        mimageView.add(o);

        ImageView a = new ImageView(this);
        a.setLayoutParams(param2);
        layout.addView(a);
        mimageView.add(a);

        ImageView d = new ImageView(this);
        d.setLayoutParams(param2);
        layout.addView(d);
        mimageView.add(d);

        ImageView i = new ImageView(this);
        i.setLayoutParams(param2);
        layout.addView(i);
        mimageView.add(i);

        ImageView n = new ImageView(this);
        n.setLayoutParams(param2);
        layout.addView(n);
        mimageView.add(n);

        ImageView g = new ImageView(this);
        g.setLayoutParams(param2);
        layout.addView(g);
        mimageView.add(g);
    }

    private void imageClear() {
        for(ImageView image:mimageView) {
            //将ImageView置为空
            image.setImageDrawable(null);
            //清除缓存
            image.destroyDrawingCache();
        }
    }

    Handler handler=new Handler()
    {

        @Override
        public void handleMessage(Message msg)
        {
            // TODO Auto-generated method stub
            switch(msg.what)
