Android UI开发第十五篇——分享一个登录缓冲界面

      今天在网上发现了一个很漂亮的缓冲界面，在这里分享一下。主要还是用的android Anim。

java code：

public class Main extends Activity {
private Animation anm;
private int marginsTop;
public List<ImageView> images;
public LinearLayout ll;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

requestWindowFeature(Window.FEATURE_NO_TITLE);

DisplayMetrics dm = this.getResources().getDisplayMetrics();

int height = dm.heightPixels;
marginsTop = height - 100;
anm = AnimationUtils.loadAnimation(this, R.anim.myanim);
ll = new LinearLayout(this);
ll.setBackgroundResource(R.drawable.background);

images = new ArrayList<ImageView>();
initImage(ll);
playAnimation();
setContentView(ll);
    }
    private void playAnimation(){    
    new Thread(){
    @Override
    public void run()
    {
    try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
int runcount=0;
    while(true)
    {
    if(runcount<2)
    {
    for(int i=0;i<=6;i++)
    {
    handler.sendEmptyMessage(i);
    try {
    Thread.sleep(400);
    } catch (InterruptedException e) {
    e.printStackTrace();
    }
    }
    runcount++;
    }else
    {
    handler.sendEmptyMessage(99);
    runcount=0;
    }


    }

    }

    }.start();
    }


    Handler handler=new Handler(){

    @Override
    public void handleMessage(Message msg) {  
    switch(msg.what)
    {
    case 0:
    images.get(0).setImageDrawable(Main.this.getResources().getDrawable(R.drawable.l));
    images.get(0).startAnimation(anm);

    break;
    case 1:
    images.get(1).setImageDrawable(Main.this.getResources().getDrawable(R.drawable.o));
    images.get(1).startAnimation(anm);
    break;
    case 2:
    images.get(2).setImageDrawable(Main.this.getResources().getDrawable(R.drawable.a));
    images.get(2).startAnimation(anm);
    break;
    case 3:
    images.get(3).setImageDrawable(Main.this.getResources().getDrawable(R.drawable.d));
    images.get(3).startAnimation(anm);
    break;
    case 4:
    images.get(4).setImageDrawable(Main.this.getResources().getDrawable(R.drawable.i));
    images.get(4).startAnimation(anm);
    break;
    case 5:
    images.get(5).setImageDrawable(Main.this.getResources().getDrawable(R.drawable.n));
    images.get(5).setAnimation(anm);
    break;
    case 6:
    images.get(6).setImageDrawable(Main.this.getResources().getDrawable(R.drawable.g));
    images.get(6).setAnimation(anm);
    break;
    case 99:
    clearImage();
    break;
    }
    }
    };
    private void clearImage()
    {
    for(ImageView image:images)
    {
    image.setImageDrawable(null);
    image.destroyDrawingCache();
    }
    }
    private void initImage(LinearLayout layout) {

    layout.setGravity(Gravity.CENTER_HORIZONTAL);
LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(40, 40);
param.setMargins(30, marginsTop, 0, 0);

LinearLayout.LayoutParams param2 = new LinearLayout.LayoutParams(40, 40);
param2.setMargins(-5, marginsTop, 0, 0);

ImageView l = new ImageView(this);
l.setLayoutParams(param);
layout.addView(l);
images.add(l);

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


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

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

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

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

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

anim code：

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"android:shareInterpolator="false"><scale android:interpolator="@android:anim/accelerate_interpolator"android:fromXScale="0.5" android:toXScale="1.2" android:fromYScale="0.5"android:toYScale="1.2" android:pivotX="50%" android:pivotY="50%"android:fillAfter="false" android:startOffset="-50"android:duration="100"/></set>
