单击第1项时的Android CarouselPicker [英] Android CarouselPicker when 1st item is click

问题描述

我在github上发现了一个包含CarouselPicker的文库 com.github.Vatican-Cameos：CarouselPicker：v1.0 我在依赖项中添加了这个，并在存储库中编译 maven {url' https://jitpack.io '}

我已成功制作CarouselPicker，这是 JAVA CODE

    List<CarouselPicker.PickerItem> itemsImage = new ArrayList<>();
    itemsImage.add(new CarouselPicker.DrawableItem(R.drawable.abc));
    itemsImage.add(new CarouselPicker.DrawableItem(R.drawable.123));
    itemsImage.add(new CarouselPicker.DrawableItem(R.drawable.colors));
    itemsImage.add(new CarouselPicker.DrawableItem(R.drawable.shapes));
    CarouselPicker.CarouselViewAdapter imageAdapter = new CarouselPicker.CarouselViewAdapter(this, itemsImage,0);
    carouselPicker.setAdapter(imageAdapter);

通过拥有LinearLayout，这是XML代码

    android:id="@+id/carouselPicker"
    android:layout_marginTop="50dp"
    android:layout_marginBottom="20dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:items_visible="three"
    />

我无法在google上找到如果旋转木马选择器中的第一项选择如 OnClickListener 更改意图

I cant find on google on what if the 1st item in the carousel picker selected like a OnClickListenerto change the intent

推荐答案

我找到了您在此链接上使用的库
您必须使用 addOnPageChangeListener 像这样：

I found a library you used on this link You must use addOnPageChangeListener like this:

carouselPicker.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
            //position of the selected item
            if(position == 0){
                startActivity(new Intent(thisActivity.this, anotherActivity1.class));
            }                
            else if(position == 1){
                startActivity(new Intent(thisActivity.this, anotherActivity2.class));
            } 
            // Same conditions for another cases.
        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
    });

那么，你想要的 onClickListener 处理click事件， onPageSelected 方法。

So, your onClickListener that you want to handle the click event, is onPageSelected method.
