1.)透明渐变动画

ImageView logo = (imageView) findViewById(R.id.image);

AlphaAnimation ani = new AlphaAnimation(0.0,1.0); //透明度从零到1变化

ani.setDuration(3000);//设置动画时长3秒

ani.setAnimationListener(new Animation(){

public void onAnimationStart(Animation ani){

//todo

}

public void onAnimationRepead(Animation ani){

//todo

}

// 动画完成后跳转到activityB

public void onAnimationEnd(Animation ani){

Intent intent = new Intent(Activity.this,activityB.class);

startActivity(intent);

}

})

 

 

2.)去掉标题和设置全屏

（1）java中实现

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

this.getwindow().setFlags(WindowManager.Layoutparam.FLAG_FULLSCREEN,WindowManager.Layoutparam.FLAG_FULLSCREEN);

(2)主体实现style 省略不写了

 

logo.setAnimation(ani);//讲动画应用到logo的显示上
