Android PagingDataAdapter二级列表滑动一级列表吸顶 安卓二级列表

先看看运行的效果：

 

 

实现步骤：

首先自定义一个ListView，代码：MyLsitView.java

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.ListView;

public class MyListView extends ListView implements Runnable {

    private float mLastDownY = 0f;
    private int mDistance = 0;
    private int mStep = 10;
    private boolean mPosirive = false;

    public MyListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }

    public MyListView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
            if (mLastDownY == 0f && mDistance == 0) {
                mLastDownY = event.getY();
                return true;
            }
            break;

        case MotionEvent.ACTION_CANCEL:
            break;

        case MotionEvent.ACTION_UP:
            if (mDistance != 0) {
                mStep = 1;
                mPosirive = (mDistance >= 0);
                this.post(this);
                return true;
            }
            mLastDownY = 0f;
            mDistance = 0;
            break;

        case MotionEvent.ACTION_MOVE:
            if (mLastDownY != 0f) {
                mDistance = (int) (mLastDownY - event.getY());
                if ((mDistance < 0 && getFirstVisiblePosition() == 0 && getChildAt(
                        0).getTop() == 0)
                        || (mDistance > 0 && getLastVisiblePosition() == getCount() - 1)) {
                    mDistance /=2;
                    scrollTo(0, mDistance);
                    return true;
                }
            }
            mDistance = 0;
            break;
        }
        return super.onTouchEvent(event);
    }

    @Override
    public void run() {
        mDistance += mDistance > 0 ? -mStep : mStep;
        scrollTo(0, mDistance);
        if (mPosirive && mDistance <=0 || (!mPosirive && mDistance >=0)) {
            scrollTo(0, 0);
            mDistance = 0;
            mLastDownY = 0f;
            return;
        }
        mStep += 1;
        this.postDelayed(this, 10);
    }
}

首页: activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <com.example.momo.MyListView
        android:id="@+id/listView"
        android:layout_width="180dp"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:background="@drawable/group_off"
        android:choiceMode="singleChoice"
        android:divider="@null"
        android:listSelector="#00000000"
        android:scrollbars="none" >
    </com.example.momo.MyListView>

    <com.example.momo.MyListView
        android:id="@+id/subListView"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="#ffffff"
        android:divider="@null" >
    </com.example.momo.MyListView>

</LinearLayout>

activity_main.xml 自定义的ListView 横向布局，然后新建父ListView的适配器：MyAdapter.java

import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.RelativeLayout;
import android.widget.TextView;

public class MyAdapter extends BaseAdapter {

    Context context;
    LayoutInflater inflater;
    String[] foods;
    int last_item;
    // int[] images;
    private int selectedPosition = -1;

    public MyAdapter(Context context, String[] foods) {
        this.context = context;
        this.foods = foods;
        // this.images = images;
        inflater = LayoutInflater.from(context);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return foods.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.mylist_item, null);
            holder = new ViewHolder();
            holder.textView = (TextView) convertView
                    .findViewById(R.id.textview);
            // holder.imageView = (ImageView) convertView
            // .findViewById(R.id.imageview);
            holder.layout = (RelativeLayout) convertView
                    .findViewById(R.id.colorlayout);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        // 设置选中效果
        if (selectedPosition == position) {
            holder.textView.setTextColor(Color.BLUE);
            holder.layout.setBackgroundResource(R.drawable.group_on);
        } else {
            holder.textView.setTextColor(Color.WHITE);
            holder.layout.setBackgroundColor(Color.TRANSPARENT);
        }

        holder.textView.setText(foods[position]);
        holder.textView.setTextColor(Color.BLACK);
        // holder.imageView.setBackgroundResource(images[position]);

        return convertView;
    }

    public static class ViewHolder {
        public TextView textView;
        // public ImageView imageView;
        public RelativeLayout layout;
    }

    public void setSelectedPosition(int position) {
        selectedPosition = position;
    }

}

 

对应的布局：mylist_item.xml

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

    <RelativeLayout
        android:id="@+id/colorlayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/textview"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:layout_marginBottom="20dp"
            android:layout_marginTop="20dip"
            android:text="美食"
            android:textSize="16sp" />
    </RelativeLayout>

</LinearLayout>

 

然后是子适配器：SubAdapter.java

import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class SubAdapter extends BaseAdapter {

    Context context;
    LayoutInflater layoutInflater;
    String[][] cities;
    public int foodpoition;

    public SubAdapter(Context context, String[][] cities, int position) {
        this.context = context;
        this.cities = cities;
        layoutInflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        this.foodpoition = position;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return cities.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return getItem(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder = null;
        final int location = position;
        if (convertView == null) {
            convertView = layoutInflater.inflate(R.layout.sublist_item, null);
            viewHolder = new ViewHolder();
            viewHolder.textView = (TextView) convertView
                    .findViewById(R.id.textview1);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }
        viewHolder.textView.setText(cities[foodpoition][position]);
        viewHolder.textView.setTextColor(Color.BLACK);

        return convertView;
    }

    public static class ViewHolder {
        public TextView textView;
    }

}

 

对应的布局：sublist_item.xml

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

    <TextView
        android:id="@+id/textview1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dip"
        android:layout_marginLeft="8dip"
        android:layout_marginTop="10dip"
        android:text="aaaaa"
        android:textSize="16sp" />

</LinearLayout>

最后是主activity的实现：MainActivity.java

import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class MainActivity extends Activity {

    private MyListView listView;
    private MyListView subListView;
    private MyAdapter myAdapter;
    private SubAdapter subAdapter;

    String cities[][] = new String[][] {
            new String[] { "全部美食", "本帮江浙菜", "川菜", "粤菜", "湘菜", "东北菜", "台湾菜",
