Android：旋转时崩溃，水平到垂直

发布于 2024-08-21 04:51:48 字数 12672 浏览 10 评论 0原文

我正在使用 android，并且正在创建一个简单的 Twitter 应用程序来测试我到目前为止所学到的内容。但我遇到了一个我不明白的问题。我创建了一个线程来获取推文，没有任何问题，但随后添加了一个 ProgressDialog 来显示该线程何时运行。这样做会导致非常不寻常的行为。如果用户从垂直方向旋转到水平方向，程序将按预期运行，没有问题，但如果他随后旋转回来，程序就会崩溃，并提示窗口泄漏。

该问题仅发生在水平到垂直布局切换时。我知道如果您在对话框运行时尝试旋转会出现问题，但我已确保对话框已完成运行并在旋转之前关闭，但它仍然会崩溃。这是我的代码：

package com.onesmartpuppy.puppytweet;
import java.util.ArrayList;
import com.github.droidfu.widgets.WebImageView;

public class PuppyTweet extends ListActivity implements OnClickListener {

    private ProgressDialog m_ProgressDialog = null;
    private ArrayList<Status> messages = null;
    private TweetAdapter m_adapter;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        messages = new ArrayList<Status>();
        this.m_adapter = new TweetAdapter(this, R.layout.row, messages);
        setListAdapter(this.m_adapter);

        setupButtons();

        m_ProgressDialog = ProgressDialog.show(this,    
             "Please wait...", "Retrieving tweets ...", true);

        Runnable findTweets = new Runnable(){
            @Override

                messages = new ArrayList<Status>();

                Twitter ourTwitter = new Twitter("*****", "******");
                messages = (ArrayList<Status>) ourTwitter.getFriendsTimeline();

                Thread.sleep(1000);
                Log.i("ARRAY", ""+ messages.size());
             } catch (Exception e) {

  private class TweetAdapter extends ArrayAdapter<Status> {

      }

      @Override

                  v = vi.inflate(R.layout.row2, null);
              }
              Status o = (Status) items.get(position);

              if (o != null) {

                      if (tt != null) {
                            tt.setText("Name: " + o.user.name);                            }

              }
              return v;

  }
}

这是崩溃的 LogCat：

I'm playing around with android, and I'm creating a simple twitter app to test what I've learned so far. But I've run into a problem that I don't understand. I created a thread to fetch the tweets, no problems there, but then added a ProgressDialog to show when that thread was running. Doing so caused a very unusual behavior. If the user rotates from Vertical orientation, to horizontal orientation, program behaves as expected, no problems, but if he then rotates back, the program crashes saying a window leaked.

The problem only happens on a horizontal to vertical layout switch. I know of the issues of if you try to rotate while the dialog box is running, but I've made sure that the dialog box has finished running and dismissed before rotating and it will still crash. Heres my code:

当您有某种异步任务在开始它的活动被销毁后即将完成时，通常会发生日志中的 WindowLeaked 异常。

当您旋转屏幕时，将重新创建该活动。根据 Android 文档，您应该保存任何实例状态在 onPause 方法中，包括确保所有异步任务都已停止。您可以使用保存的包在 onCreate 方法中重新创建。

The WindowLeaked exception in the log usually happens when you have some sort of async task that is finishing after the activity that began it is destroyed.

When you rotate the screen, the activity is recreated. Per the Android docs, you should save any instance state in the onPause method, including making sure that any async tasks are stopped. You can recreate in the onCreate method, using the saved bundle.
