我想为我的项目制作图像滑块，而不是使用这个库https://github.com/smarteist/android-image-slider。

但是当我复制并粘贴代码在我MainActivity的动画里面(SliderLayout.Animations.FILL)是红色的？

public class MainActivity extends AppCompatActivity {

SliderLayout sliderLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    sliderLayout = findViewById(R.id.imageSlider);
    sliderLayout.setIndicatorAnimation(SliderLayout.Animations.FILL); //set indicator animation by using SliderLayout.Animations. :WORM or THIN_WORM or COLOR or DROP or FILL or NONE or SCALE or SCALE_DOWN or SLIDE and SWAP!!
    sliderLayout.setScrollTimeInSec(1); //set scroll delay in seconds :
    setSliderViews();

}
private void setSliderViews() {

    for (int i = 0; i <= 3; i++) {

        SliderView sliderView = new SliderView(this);

        switch (i) {
            case 0:
                sliderView.setImageUrl("https://images.pexels.com/photos/547114/pexels-photo-547114.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=750&w=1260");
                break;
            case 1:
                sliderView.setImageUrl("https://images.pexels.com/photos/218983/pexels-photo-218983.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=750&w=1260");
                break;
            case 2:
                sliderView.setImageUrl("https://images.pexels.com/photos/747964/pexels-photo-747964.jpeg?auto=compress&cs=tinysrgb&h=750&w=1260");
                break;
            case 3:
                sliderView.setImageUrl("https://images.pexels.com/photos/929778/pexels-photo-929778.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=750&w=1260");
                break;
        }

        sliderView.setImageScaleType(ImageView.ScaleType.CENTER_CROP);
        sliderView.setDescription("setDescription " + (i + 1));
        final int finalI = i;
        sliderView.setOnSliderClickListener(new SliderView.OnSliderClickListener() {
            @Override
            public void onSliderClick(SliderView sliderView) {
                Toast.makeText(MainActivity.this, "This is slider " + (finalI + 1), Toast.LENGTH_SHORT).show();
            }
        });

        //at last add this view in your layout :
        sliderLayout.addSliderView(sliderView);
    }
}

从这个这个库。你可以看到。有一个com.smarteist.autoimageslider.SliderAnimations类是导入的。

import com.smarteist.autoimageslider.SliderAnimations;
import com.smarteist.autoimageslider.SliderLayout;
import com.smarteist.autoimageslider.DefaultSliderView;
import com.smarteist.autoimageslider.SliderView;

但在你的情况下。只有这两个。

 import com.smarteist.autoimageslider.SliderLayout;
import com.smarteist.autoimageslider.SliderView;

所以从你的库中导入动画类。

利用：

sliderLayout.setIndicatorAnimation(IndicatorAnimations.FILL)
