点击ListView闪退

[android砖家]

一点击ListVIew就闪退，调试了两天了，好痛苦，望大家解救。

这是部分日志

02-06 10:58:39.207: E/InputEventReceiver(764): Exception dispatching input event.
02-06 10:58:39.207: E/MessageQueue-JNI(764): Exception in MessageQueue callback:handleReceiveCallback
02-06 10:58:39.377: E/MessageQueue-JNI(764): java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ListView(16908298, class android.widget.ListView) with Adapter(class android.widget.SimpleAdapter)]
02-06 10:58:39.377: E/MessageQueue-JNI(764): at android.widget.ListView.layoutChildren(ListView.java:1538)


部分代码：

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_clear);
bar = (ProgressBar) findViewById(R.id.progressBar0);
list = new ArrayList>();
SimpleAdapter adapter = new SimpleAdapter(this, list,
R.layout.list_view, new String[] { "name", "size", "path"},
new int[] { R.id.name, R.id.size, R.id.path });
setListAdapter(adapter);
System.out.println("hh");

handler = new MyHandler();

thread = new MyThread();
thread.start();

}

private void SendMessage(String name, String path, String size) {
Message message = handler.obtainMessage();
HashMap hashMap = new HashMap();
hashMap.put("name", name);
hashMap.put("path", path);
hashMap.put("size", size);
message.obj = hashMap;
handler.sendMessage(message);

}

class MyHandler extends Handler {

@Override
public void handleMessage(Message msg) {
HashMap<String, String> hashMap = (HashMap<String, String>) msg.obj;
list.add(hashMap);
}

没有在子线程改UI，只是用Handler往ArrayList添加东西，Adapter是在主线程生成和设置的。



添加下面这些代码，点击ListView时打印不出“Click”，直接退出了。

protected void onListItemClick(ListView l, View v, int position, long id) {
System.out.println("Click");
}

[哎，真难]

报错的意思是说你的加载的SimpleAdapter有问题，不然你自己写一个adatper不要去继承已经提供的SimpleAdapter，，，

添加数据后adapter.notifyDataSetChanged();

[MR__P]

The content of the adapter has changed but ListView did not receive a notification 你的adapter没有刷新 class MyHandler extends Handler { @Override public void handleMessage(Message msg) { HashMap<String, String> hashMap = (HashMap<String, String>) msg.obj; list.add(hashMap); 这里加上adapter.notifyDataSetChanged(); }

[MR__P]

还有你的代码的质量不太好， thread = new MyThread(); thread.start();这个有什么用。 public void handleMessage(Message msg) { 这里面最好用switch（msg.what）判断一下 } 调用handler.sendE...

我查资料时别人也是这样说，但加上这句后报空指针异常（就单单加这一句，其它什么都没改），求指教。[/quote] 你这个是demo吗？发给我给你调调

这个你搞定没？我也碰到了，找到问题所在了：1.就是在你的list.clear()以后没有adapter.notifyDataSetChanged(); 2.就是确保setadapter的值是在此类里面public MyAdapter(Context context,ArrayList<ShowParams> sList){ super(); this.context=context; this.sList=(ArrayList<ShowParams>) sList.clone(); this.inf=LayoutInflater.from(context); } 也就是将this.sList=sList;改为this.sList=(ArrayList<ShowParams>) sList.clone();就行了

同样遇到这个问题，楼主解决了吗？
