通过viewflipper方法来设置图片的滚动播放

Activity代码

public class MainActivity extends AppCompatActivity {
    private ViewFlipper viewFlipper;
    public int[]resid={R.mipmap.ic_launcher,R.mipmap.ic_launcher,R.mipmap.ic_launcher,R.mipmap.ic_launcher};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        viewFlipper=(ViewFlipper)findViewById(R.id.viewflipper);
        //动态导入的方法加载viewfilpper
        for(int i =0;i<resid.length;i++){
            viewFlipper.addView(imageView(resid[i]));
            //为viewfliper添加动画效果
            viewFlipper.setInAnimation(this,R.anim.leftin);
            viewFlipper.setOutAnimation(this,R.anim.leftin);
            //设定切换的时间间隔
            viewFlipper.setFlipInterval(3000);
            viewFlipper.startFlipping();
        }
    }
    public ImageView imageView(int resID){
        ImageView imageView=new ImageView(this);
        imageView.setBackgroundResource(resID);
        return imageView;
    }
}

其中anim.leftin是自定义的动画效果，在之后的课程中会讲到
