Anroid类似QQ好友分组悬浮Demo_联系人PinnedHeaderListView源代码

Android中、大家都用过ListView、ExpandableListView等、也许你还用过PinnedHeaderListView、但是如果我说PinnedHeaderExpandableListView、你听过吗？还有可下拉的PinnedHeaderExpandableListView呢？

没听过也不要紧、本文就是介绍这个东西的、为了让大家有更直观的了解、先上效果图、通过效果图可以看出、首先它是一个ExpandableListView、但是它的头部可以固定、其次、在它的上面还有一个头部可以来回伸缩、恩、这就是本文要介绍的自定义view、为了提高复用性、这个效果我分成来了2个view来实现

第一个是PinnedHeaderExpandableListView来实现头部固定的ExpandableListView、第二个view是StickyLayout、这个view具有一个可以上下滑动的头部、最后将这2个view组合在一起、就达到了如下的效果

onCreate()代码

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    expandableListView = (PinnedHeaderExpandableListView) findViewById(R.id.expandablelist);
    //stickyLayout = (StickyLayout)findViewById(R.id.sticky_layout);
    initData();

    adapter = new MyexpandableListAdapter(this);
    expandableListView.setAdapter(adapter);

    // 展开所有group
    for (int i = 0, count = expandableListView.getCount(); i < count; i  ) {
        expandableListView.expandGroup(i);
    }

    expandableListView.setOnHeaderUpdateListener(this);
    expandableListView.setOnChildClickListener(this);
    expandableListView.setOnGroupClickListener(this);
    //stickyLayout.setOnGiveUpTouchEventListener(this);

}

getGroupView()代码

public View getGroupView(int groupPosition, boolean isExpanded,
        View convertView, ViewGroup parent) {
    GroupHolder groupHolder = null;
    if (convertView == null) {
        groupHolder = new GroupHolder();
        convertView = inflater.inflate(R.layout.group, null);
        groupHolder.textView = (TextView) convertView
                .findViewById(R.id.group);
        groupHolder.imageView = (ImageView) convertView
                .findViewById(R.id.image);
        convertView.setTag(groupHolder);
    } else {
        groupHolder = (GroupHolder) convertView.getTag();
    }

    groupHolder.textView.setText(((Group) getGroup(groupPosition))
            .getTitle());
    if (isExpanded)// ture is Expanded or false is not isExpanded
        groupHolder.imageView.setImageResource(R.drawable.expanded);
    else
        groupHolder.imageView.setImageResource(R.drawable.collapse);
    return convertView;
}

getChildView()代码

public View getChildView(int groupPosition, int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent) {
    ChildHolder childHolder = null;
    if (convertView == null) {
        childHolder = new ChildHolder();
        convertView = inflater.inflate(R.layout.child, null);

        childHolder.textName = (TextView) convertView
                .findViewById(R.id.name);
        childHolder.textAge = (TextView) convertView
                .findViewById(R.id.age);
        childHolder.textAddress = (TextView) convertView
                .findViewById(R.id.address);
        childHolder.imageView = (ImageView) convertView
                .findViewById(R.id.image);
        Button button = (Button) convertView
                .findViewById(R.id.button1);
        button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "clicked pos=", Toast.LENGTH_SHORT).show();
            }
        });

        convertView.setTag(childHolder);
    } else {
        childHolder = (ChildHolder) convertView.getTag();
    }

    childHolder.textName.setText(((People) getChild(groupPosition,
            childPosition)).getName());
    childHolder.textAge.setText(String.valueOf(((People) getChild(
            groupPosition, childPosition)).getAge()));
    childHolder.textAddress.setText(((People) getChild(groupPosition,
            childPosition)).getAddress());

    return convertView;
}
