android基础---简易闪屏操作，通过动画实现

1.通过动画的渐变效果，将图片进行变化，设置一个漂亮的跳转！！！

Splash.java:

public class Splash extends Activity {

private ImageView iv_splash;
Intent intent;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

//隐藏标题栏与全屏显示

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splash);

iv_splash=(ImageView) findViewById(R.id.iv_splash);

//初始化动画

AlphaAnimation animation=new AlphaAnimation(0.1f, 1.0f);

//设置动画运行的时间

animation.setDuration(3000);

//将动画加载到图片中

iv_splash.setAnimation(animation);
animation.setAnimationListener(new AnimationListener() {
/
@Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub

}

@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub

}
//动画结束时进行的操作
@Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
intent=new Intent(Splash.this, MainActivity.class);
startActivity(intent);
finish();
}
});

}

//可以通过触摸事件来结束动画

@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
super.onTouchEvent(event);
intent=new Intent(Splash.this, MainActivity.class);
startActivity(intent);
finish();
return true;

}

2.布局文件：splash.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    
    <ImageView 
        android:id="@+id/iv_splash"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:src="@drawable/a6"
        android:scaleType="fitXY"
        />
</LinearLayout>
