handler和ProgressDialog这种写法貌似正确，但是我隐约觉得有错误

Question

我是看网页上的例子写的首先A页面中写Handler handler = new Handler();
     Runnable mTasks = new Runnable() {
       public void run() {
       myDialog = ProgressDialog.show(Stu80Activity.this, "O(∩_∩)O", "网络数据加载中，请稍后...", true);
       Intent intent=new Intent();
             intent.setClass(Stu80Activity.this,list.class);
             Bundle bundle=new Bundle();
             bundle.putString("param", param);
             intent.putExtras(bundle);
             startActivity(intent);
        }
     };
         
     //handler.postDelayed(mTasks,1000);   
      handler.post(mTasks);  
public static void closeProgressDialog() {
     myDialog.dismiss();
     }
    
然后B页面中
private static final int EVENT_TIME_TO_CHANGE_IMAGE = 100;
private Handler mHandler = new Handler() {
public void handleMessage(Message msg) {
      switch(msg.what){
        case EVENT_TIME_TO_CHANGE_IMAGE:
             Stu80Activity.closeProgressDialog();
        break;
     }
}}; Message message = mHandler.obtainMessage(EVENT_TIME_TO_CHANGE_IMAGE);
        mHandler.sendMessage(message);这种写法没报错，运行出来的样子就是在A页面点击，出现一个“正在加载中”的框框，然后跳转到B页面，我发现的问题是正在加载中的旋转轮 只转动大约1厘米，，本来没什么，但是b页面调用网络数据大小不一样，  每次都是转动大约1厘米，，就感觉不正常了而且框框没有出现在B页面上，都是在A页面上出来了一下，就跳到B页面，没在B页面上停留片刻。问题出在哪里？？？

Answer 1

你有没有认真看过我昨天回复的代码？
你的myDialog是在AActivity中，连Activity都转到B了，还想看到什么myDialog？
我昨天说了，A直接转到B，B中声明myDialog，首先显示它，
再新开线程调用网络数据，完成加载后用Handler关闭自身Activity中的myDialog，
就这么简单，我不知道你有什么想问的，帖子都发了好几个了。

Answer 2

1　A直接转到B
2　B中onCreate事件声明并show你的Dialog
3　新开线程调用网络数据
4　完成加载后通知Handler关闭Dialog以上4步按顺序来写，有哪一步是你不会的？

Answer 3

http://topic.csdn.net/u/20120604/15/e5a2a43a-d174-468e-8741-78afc56139f3.html这个是我的B页面代码也就是说 步骤 2,3,4不会你看看。b页面感觉代码复杂，，没你说的那么容易吧。

Answer 4

就是这么容易。
我只改了你的onCreate事件，和新增了一个Handler private Handler handler=new Handler(){
public void dispatchMessage(android.os.Message msg) {
switch (msg.what) {
case 0:
mydialog.cancel();
break; default:
break;
}
};
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mydialog = ProgressDialog.show(Stu80Activity.this, "加载中...",
"请稍等片刻...", true);
new Thread() {
public void run() {
try {
// 涉及到网络访问的操作，用多线程来实现
items = getItems(1);
} catch (Exception e) {
e.printStackTrace();
} finally {
//最终通知handler关闭mydialog
handler.sendEmptyMessage(0);
}
}
}.start();
ls = (ListView) findViewById(R.id.ls);
ls.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
TextView ls_id_i = (TextView) arg1.findViewById(R.id.ls_id); /*
 * Toast.makeText(getApplicationContext(), ls_id_i.getText(),
 * Toast.LENGTH_SHORT).show();
 */
Intent intent = new Intent();
intent.setClass(Stu80Activity.this, content.class);
Bundle bundle = new Bundle();
bundle.putString("id", ls_id_i.getText().toString());
intent.putExtras(bundle);
startActivity(intent);
}
});
bt1 = (Button) findViewById(R.id.bt1);
bt2 = (Button) findViewById(R.id.bt2);
bt1.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
if (num > 0) {
num--;
}
display(items_m);
}
});
bt2.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
if (num * 12 < items_m.size()) {
num++;
}
display(items_m);
}
}); items_m = items;
display(items); // 添加Spinner事件监听
Spinner sp = (Spinner) findViewById(R.id.sp);
ArrayAdapter ada = ArrayAdapter.createFromResource(this, R.array.list,
android.R.layout.simple_spinner_item);
ada.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp.setAdapter(ada);
// 定义子元素选择监听器
sp.setSelection(0, false);
sp.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
// Toast.makeText(Stu80Activity.this,"选择的色彩： " +
// parent.getItemAtPosition(position).toString(),
// Toast.LENGTH_LONG).show();
String pos = parent.getItemAtPosition(position).toString();
// TextView tv=(TextView) findViewById(R.id.logotitle);
// tv.setText(pos);
pos = pos.substring(0, 2);
jump(pos);
} @Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}

我刚才写的代码没问题，自己先找找看 

Answer 8

把这两行代码也放到handler中来处理        items_m=items;
        display(items); 

Answer 9

175行是这个
public void display(ArrayList items)
        {
        if(num*12>items.size())
        {
             x=items.size();
        }
跟new Thread() {
            public void run() {
                try {
                    // 涉及到网络访问的操作，用多线程来实现
                     items = getItems(par);
                } catch (Exception e) {是同一个啊，，难道有啥问题？？

Answer 12

多线程那不改，把这两行代码也放到handler中来处理  items_m=items;
  display(items);

Answer 13

himi_  ，加我qq吧  要么我把整个文件项目给你调试调试

Answer 14

是报错了　非UI线程不能更改UI线程的控件，
display(items);
这个方法中有对UI控件进行操作　所以不能放到子线程中，
改到handler中来处理

Answer 15

我访问不了你的WebService　
目前只是display(items);这个设置适配器这里出了问题，
你把这个方法放到关闭Dialog之后来进行调用。
