主要原理：就是利用nineold提供的动画帮助类，做一个放大效果，子线程或者hanlder发消息延时两秒，然后再执行放大效果对图片
当然需要添加依赖

compile 'com.nineoldandroids:library:2.4.0'

布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent">    <ImageView        android:id="@+id/splash"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:adjustViewBounds="true"        android:scaleType="centerCrop"        android:src="@drawable/default_splash"/></RelativeLayout>

代码：

protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                WindowManager.LayoutParams.FLAG_FULLSCREEN);        setContentView(R.layout.splash);        splash = (ImageView) findViewById(R.id.splash);        //方法一：开启一个子线程执行跳转任务        new Thread(){            @Override            public void run() {                super.run();                try {                    Thread.sleep(2000);                    Splash.this.runOnUiThread(new Runnable() {                        @Override                        public void run() {                            animateImage();                        }                    });                } catch (InterruptedException e) {                    e.printStackTrace();                }            }        }.start();    }    //放大图片    public void animateImage() {        ObjectAnimator animatorX = ObjectAnimator.ofFloat(splash, "scaleX", 1f,                1.2f);        ObjectAnimator animatorY = ObjectAnimator.ofFloat(splash, "scaleY", 1f,                1.2f);        AnimatorSet set = new AnimatorSet();        set.setDuration(2000).play(animatorX).with(animatorY);        set.start();        set.addListener(new AnimatorListenerAdapter() {            @Override            public void onAnimationEnd(Animator animation) {                startActivity(new Intent(Splash.this, MainActivity.class));                Splash.this.finish();                overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);            }        });    }
