我这里有这段代码：我这里有这段代码：我这里有这段代码：

public class MainTask extends Activity {

private boolean flag=false;
private Context context;
private String url;
private ProgressDialog pd;
private View view;

public MainTask(Context context,String url,View view) {
    this.url=url;
    this.view=view;
    this.context=context;
    BitmapDownloaderTask task = new BitmapDownloaderTask();
    task.execute();
}


private Void MainThread() {
    int  leave=0;
    int  pass=0;

    while(true){

        if(leave==-1){
            flag=true;
            break;
        }
        else if(pass==Preferences.vcheckimage.size())
            break;

        for(int i=0;i<Preferences.vcheckimage.size();i++){

            if(Preferences.vcheckimage.get(i).equals("-1")){
                leave=-1;
                break;
            }
            else{
                pass++;
            }
        }
    return null;  
}


private class BitmapDownloaderTask extends AsyncTask<Void, Void, Void> {

    public BitmapDownloaderTask() {

    }

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        view.setEnabled(false);
        pd = new ProgressDialog(context);
        pd.setTitle("Processing...");
        pd.setMessage("Please wait.");
        pd.setCancelable(false);                  
        pd.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

        pd.setIndeterminate(true);
        pd.show();
    }

    @Override
    protected Void doInBackground(Void... params) {
        return MainThread();
    }

     @Override
     protected void onPostExecute(Void result) {

        pd.dismiss();

        if(flag){           
         Toast.makeText(context,"Image is not available yet.", Toast.LENGTH_LONG).show();

        }

    }
}
 }

但是当我运行这个时，我得到以下错误：

有谁知道为什么会这样？我看到和其他帖子但没有帮助我。

先谢谢。

我想BitmapDownloaderTask 属于MainThread的内部是整个问题。尝试匹配括号，解决问题。

修改最后一点来自我的身边。我的MainThread代码就是这个

private Void MainThread() { int leave = 0; int pass = 0; while(true) { if(leave==-1) { flag=true; break; } else if(pass==Preferences.vcheckimage.size()) break; for(int i=0;i<Preferences.vcheckimage.size();i++) { if(Preferences.vcheckimage.get(i).equals("-1")) { leave=-1; break; } else { pass++; } } break; } return null; }

Activity已泄漏最初添加了进度对话框的窗口
