Listview排行榜，前三名排名用不同图片代表

老规矩，先看图，适合你的再往下看：

这是一个listview，展示100条数据。之后是先加载10条，点击加载更多显示全部。

第一步，先写布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/iv_tuition"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="@dimen/dimen_10dp"
        android:scaleType="fitXY"
        android:src="@drawable/img_income"
        android:visibility="gone" />

    <com.dyh.frame.widget.AutoHeightListView
        android:id="@+id/lv_tuiton_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="@dimen/dp_5"
        android:layout_marginTop="@dimen/dp_10"
        android:divider="@color/dividerColor_view"
        android:dividerHeight="@dimen/dp_0.5" />


    <TextView
        android:id="@+id/tv_more"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="@dimen/dimen_20dp"
        android:background="@color/white"
        android:gravity="center"
        android:padding="@dimen/dimen_10dp"
        android:text="查看更多"
        android:textColor="@color/app_button_price"
        android:textSize="@dimen/dimen_15sp" />

</LinearLayout>

以上是一个图片显示排行榜，其次是listview，最后是一个Textview用来加载全部数据。

接下来就是代码：

Activity:

private TextView mTvmore;
private ImageView mIvtuition;

mTvmore = (TextView) findViewById(R.id.tv_more);//查看更多
mTvmore.setOnClickListener(this);
mIvtuition = (ImageView) findViewById(R.id.iv_tuition);//收入榜图片

@Override加载更多的点击事件
public void onClick(View v) {
    switch (v.getId()) {
        //排行榜显示更多
        case R.id.tv_more:
            //要对适配器和listview进行判空，否则会出现空指针
            if (incoAdapter != null) {
                if (!ListUtil.isNullOrEmpty(list1listview)) {
                    if (isShort) {
                        incoAdapter.setDataList(list1listview);
                        mTvmore.setText("收起");
                        isShort = false;
                    } else {
                        incoAdapter.setDataList(list1listview.subList(0, 10));
                        mTvmore.setText("查看更多");
                        isShort = true;
                    }
                }

}

    DefaultStringRequestNew req = new DefaultStringRequestNew(mContext, HostStudentNew.EARN_TUITION_INCOM, new ResponseListenerNew(mContext) {
        @Override

            //解析其余详情数据
            IncomeBean incoBean = JsonUtils.fromJson(response, IncomeBean.class);

        mTvmore.setVisibility(View.GONE);
    }
    mLvtuitonlist.setAdapter(incoAdapter);
}

最后是适配器：
首先适配器布局：

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

    android:layout_width="match_parent"
    android:layout_height="wrap_content"

    android:background="@color/white"
    android:padding="@dimen/dimen_8dp">

    <TextView
        android:id="@+id/tv_incom"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/dimen_7dp" />

    <com.itheima.roundedimageview.RoundedImageView
        android:id="@+id/user_icon"
        android:layout_width="40dp"

            android:textColor="@color/tc_gray_3"
            android:maxLength="10"
            android:ellipsize="end"
            android:textSize="@dimen/dimen_14sp" />

        <TextView

    </LinearLayout>


    <TextView
        android:id="@+id/tv_price"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_centerVertical="true"
        android:layout_marginRight="@dimen/dimen_10dp"

        android:textColor="@color/tc_gray_3"

</RelativeLayout>

        super(mContext, dataList);
    }

    @Override

    }

    @Override

        }

        if (dataItem.getOrderNumber() == 1) {
            mTvincom.setBackgroundResource(R.drawable.img_one);
            mTvincom.setText("");

            mTvincom.setText(" " + dataItem.getOrderNumber());
        }
    }

}

好了，这就是主要代码了，有不全的可以问我。感谢大家支持
