Android中更改SQLite数据库中的数据后，刷新ListView。

<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" >
<ListView
android:id="@+id/list_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"/>
</android.support.v4.widget.SwipeRefreshLayout>

swipeRefresh = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh);
swipeRefresh.setColorSchemeResources(R.color.colorPrimary);//设置下拉刷新进度条的颜色
swipeRefresh.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { //设置下拉刷新的监听器
@Override
public void onRefresh() {
new Thread(new Runnable() {
@Override
public void run() {
try{
Thread.sleep(1000);
}catch (InterruptedException e){}
runOnUiThread(new Runnable() {
@Override
public void run() {
mlist.clear();
initMemoData();
memoAdapter.notifyDataSetChanged();
swipeRefresh.setRefreshing(false);
}
});
}
}).start();
}
});
