Question

android simpleadapter可以重新填充吗？如何清除？

Answer 1

simpleadapter 传入的参数是List 对象，List对象当然可以重新填充，清除。

Answer 2

你随便放的什么数据，把数据放进去后
SimpleAdapter simpleAdapter;
simpleAdapter.notifyDataSetChanged();
simpleAdapter.notifyDataSetInvalidated();
调这两个方法，源码在下边，然后再通知adapter相对应的组件更新就可以啦。
/**
* Notifies the attached View that the underlying data has been changed
* and it should refresh itself.
*/
public void notifyDataSetChanged() {
mDataSetObservable.notifyChanged();
}

public void notifyDataSetInvalidated() {
mDataSetObservable.notifyInvalidated();
}

Answer 3
