ScrollView中嵌套ListView 滑動衝突

1、在不知道ListView的Item個數時，用這種方法獲取Listview的高度

	/**
	* 獲取listview item高度
	* 
	* @param listView
	*/
	public static void setListViewHeightBasedOnChildren(ListView listView) {
		ListAdapter listAdapter = listView.getAdapter();
		if (listAdapter == null) {
			return;
		}

		int totalHeight = 0;
		for (int i = 0; i < listAdapter.getCount(); i++) {
			View listItem = listAdapter.getView(i, null, listView);
			// ListView的每個Item必須是LinearLayout，不能是其他的，因爲其他的Layout(如RelativeLayout)沒有重寫onMeasure()，這裏onMeasure()時拋出異常。
			listItem.measure(0, 0);

			totalHeight += listItem.getMeasuredHeight();
		}
		totalHeight += 10;

		ViewGroup.LayoutParams params = listView.getLayoutParams();
		params.height = totalHeight
		        + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
		((MarginLayoutParams) params).setMargins(10, 10, 10, 10);
		listView.setLayoutParams(params);
	}

ListView lv = (ListView) findViewById(R.id.list);
SimpleAdapter sap = new SimpleAdapter(this, al, R.layout.list_item,
new String[] { "name", "icon" }, new int[] { R.id.title,R.id.icon });
lv.setAdapter(sap);
setListViewHeightBasedOnChildren(lv)

2、 listview個數較少，

在ScrollView中添加一屬性 android:fillViewport="true"  ，這樣就可以讓ListView全屏顯示了
指定ListView的總高度 android:layout_height="450dp" ; 

指定ListView的Item高度  android:layout_height="45dp"
