这是我的按钮活动的代码，我设法添加了一个进度对话框，所以当活动科学技术正在加载它的显示加载时......只是它没有旋转，所以我想知道我做错了什么，也许有人可以寻找我的错误这是代码：

package net.thinkbin;

import android.app.Activity;
import android.app.ProgressDialog;

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tutorial1);

    Button share = (Button) findViewById(R.id.button2);
    share.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
            // TODO Auto-generated method stub
            startActivity(new Intent("net.thinkbin.SHARE"));
            overridePendingTransition(0, 0);
            finish();
        }
    });

我不能确定，但​​我只见过Handler或AsyncTask曾经运行过一个单独的线程。无论哪种方式，这是一个在 android 中使用进度条的示例。

你目前的做法是非常规的。

要获得 ICS 之前的旋转式动作，您应该调用

showDialog(int);

并覆盖

onCreateDialog(int);

设置微调器样式。

发布 ICS 他们已经用 FragmentManager 替换了所有这些，所以你应该用它来创建旋转风格的动作。

你最好在 Android 中使用 AsynTask 而不是 Thread。

Button sciencetechnology = (Button) findViewById(R.id.button6);
sciencetechnology.setOnClickListener(new View.OnClickListener() {

                public void onClick(View v) {
        // TODO Auto-generated method stub
       UrTask u=new UrTask ();
       u..execute();


    }
});

异步任务 

public class UrTask extends
        AsyncTask<Void, Void, Void> {

    ProgressDialog pDialog;

    protected void onPreExecute() {
        pDialog = new ProgressDialog(ActivityName.this);
        pDialog.setMessage("Downloading Data...");
        pDialog.setCancelable(false);
        pDialog.show();

    }

    protected Void doInBackground(Void... unused) {

        // Do ur work

        return (null);
    }

    @Override
    protected void onProgressUpdate(Void... values) {
        // TODO Auto-generated method stub
        super.onProgressUpdate(values);
    }

    protected void onPostExecute(Void unused) {
        pDialog.dismiss();
    }

}
