android ScrollView嵌套Listview

标签：android

如果按照平常的设置，ScrollView里面的ListView是无法显示全部的，而且还不能滑动，从stackover flow搜的代码，亲测可以用！

1>给listView设置点击监视事件：

ListView lv = (ListView) findViewById(R.id.layout_lv);
lv.setOnTouchListener(new OnTouchListener() {
    // Setting on Touch Listener for handling the touch inside ScrollView
    @Override
    public boolean onTouch(View v, MotionEvent event) {
    // Disallow the touch request for parent scroll on touch of child view
    v.getParent().requestDisallowInterceptTouchEvent(true);
    return false;
    }
});

2>给listView设置高度自适应的方法：

/**** Method for Setting the Height of the ListView dynamically.
 **** Hack to fix the issue of not showing all the items of the ListView
 **** when placed inside a ScrollView  ****/
public static void setListViewHeightBasedOnChildren(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null)
        return;

    int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.UNSPECIFIED);
    int totalHeight = 0;
    View view = null;
    for (int i = 0; i < listAdapter.getCount(); i++) {
        view = listAdapter.getView(i, view, listView);
        if (i == 0)
            view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, LayoutParams.WRAP_CONTENT));

        view.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
        totalHeight += view.getMeasuredHeight();
    }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
    listView.requestLayout();
}
3>让listView应用该设置：

ListView list = (ListView) view.findViewById(R.id.ls);
setListViewHeightBasedOnChildren(list);
ok，搞定~~~
