当我从 github https://github.com/smarteist/android

Question

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;

        }

    }

}

Answer 1

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。&nbsp;import com.smarteist.autoimageslider.SliderLayout;import com.smarteist.autoimageslider.SliderView;所以从你的库中导入动画类。

Answer 2

采用：sliderLayout.setIndicatorAnimation(IndicatorAnimations.FILL)
