Android ListView表单实现多选删除，高度随表单项多少变化

今天自己完成了一个ListView表单，这个表单可以实现多选删除，

视图对应的Acticity类

private ListView an_passengerList;

private LinearLayout an_passengerList_layout;

an_passengerList_layout= (LinearLayout) findViewById(R.id.an_passengerList_layout);

an_passengerList= (ListView) findViewById(R.id.an_passengerList);

an_passengerList_layout.setVisibility(View.VISIBLE);

an_passengerList.setVisibility(View.VISIBLE);

fpassergerListAdapter= new FlyPassergerListAdapter(mContext, cacheSp, pChoosedList);

an_passengerList.setAdapter(fpassergerListAdapter);

fpassergerListAdapter.notifyDataSetChanged();

/**

* 乘车人删除后 更新视图（ListView的大小应该可以根据项目的多少，自适应高度）

*/

public void refreshPassengerList(){

int totalHeight = 0;

for (int i = 0; i < fpassergerListAdapter.getCount(); i++) {

View listItem = fpassergerListAdapter.getView(i, null, an_passengerList);

listItem.measure(0, 0);

totalHeight += listItem.getMeasuredHeight();

}

ViewGroup.LayoutParams params = an_passengerList.getLayoutParams();

params.height = totalHeight + (an_passengerList.getDividerHeight() * (fpassergerListAdapter.getCount() -1));

((ViewGroup.MarginLayoutParams)params).setMargins(10, 10, 10, 10);

an_passengerList.setLayoutParams(params);

}

List对应的adapter

}

}

});

对应的xml文件（listview）

<LinearLayout

android:id="@+id/an_passengerList_layout"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:background="#FFFFFF"

android:orientation="horizontal"

android:visibility="gone">

<ListView

android:id="@+id/an_passengerList"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:visibility="gone"

>

</ListView>

</LinearLayout>

对应的xml文件（listview中的每一项 an_adapter_passengers）
