一点击ListView就闪退

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.

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);


    }

}

模式错了,不能在线程内更改UI部分
已经提示了:
Make sure the content of your adapter is not modified from a background thread, but only from the UI thread.
解决方法:
把线程内更新ui部分的内容提出来放到主线程里
然后在子线程内仅调用它即可
可把需要的参数传过来的

我也出现了上面的问题,我想知道,点击listView不算是修改UI吧,只是一个传值跳转的动作啊
