两个接口实现多条目+ImageLoad图片圆形效果

版权声明：叮叮叮！！！！ https://blog.csdn.net/Xuexx_520/article/details/83027694

开始布局

两个接口为头条，国内。需要加载完头条数据，再展示国内数据

头条布局如下（不带图片）

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="16dp"
    >

    <TextView
        android:id="@+id/title"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:maxLines="1"
        android:text="标题"
        android:textColor="#000"
        android:textSize="20sp"
        app:layout_constraintBottom_toTopOf="@id/author"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        />

    <TextView
        android:id="@+id/author"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:maxLines="1"
        android:text="作者"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@id/title"
        />
</android.support.constraint.ConstraintLayout>

国内布局如下（包含图片）

<?xml version="1.0" encoding="utf-8"?>

    >

    <ImageView
        android:id="@+id/iv"
        android:layout_width="160dp"
        android:layout_height="100dp"

        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        />

    <TextView
        android:id="@+id/title"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:maxLines="1"
        android:text="标题"
        android:textColor="#000"
        android:textSize="20sp"
        app:layout_constraintBottom_toTopOf="@id/author"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toLeftOf="@id/iv"
        app:layout_constraintTop_toTopOf="parent"
        />

    <TextView

        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:maxLines="1"
        android:text="作者"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toLeftOf="@id/iv"
        app:layout_constraintTop_toBottomOf="@id/title"
        />
</android.support.constraint.ConstraintLayout>

Adapter多加了getItemViewType和getViewTypeCount()方法进行多条目加载

package adapter;

import android.view.View;

public class MAdapter extends BaseAdapter{
    private MainActivity mainActivity;
    private ArrayList<News.ResultBean.DataBean> list;

    public MAdapter(MainActivity mainActivity, ArrayList<News.ResultBean.DataBean> list) {
        this.mainActivity = mainActivity;
        this.list = list;
    }


    //当前item是什么类型
    @Override
    public int getItemViewType(int position) {
        News.ResultBean.DataBean data= (News.ResultBean.DataBean) getItem(position);
        //头条类型
        if(data.isTT()){
            return super.getItemViewType(position);
        }
        //国内类型
        if (data.isCN()) {
            return 1;
        }

    }

    @Override

           vh=new ViewHolder(convertView);

        } else {

    @Override

        return list.size();
    }

  
    @Override

        return list.get(position);
    }

   
    @Override

    }
    public class ViewHolder {
        TextView title;
        TextView author;
        ImageView iv;

        public ViewHolder(View viewItem) {
            title=viewItem.findViewById(R.id.title);
            author=viewItem.findViewById(R.id.author);
            //国内
            iv=viewItem.findViewById(R.id.iv);

        }
        public void bindData(News.ResultBean.DataBean data){
            title.setText(data.getTitle());
            author.setText(data.getAuthor_name());
            if(data.isCN()){
                ImageLoader.getInstance().displayImage(data.getThumbnail_pic_s(),iv, ImageloadConfigs.getOps(mainActivity));

            }

        }
    }


}
