我们正在运行一个长时间运行的应用程序（运行超过 5 小时）来跟踪通过 GPS 的路径。随着时间的推移，我们不会增加任何数据。使用一些全局变量来保持距离和时间。但是当我们尝试显示对话框时，我们会崩溃，但很难重现。这是堆栈跟踪

和许多其他解决方案，每个人都告诉检查activity.isFinishing()，甚至我没有使用getApplicationContext() 来显示对话框。当我们没有调用finish()时，这很奇怪。请让我知道你的想法。

用于显示单击按钮时的对话框的 Java 代码：

单击按钮时调用的 HandleEndTrip() 方法

对于所有关于活动的事件处理程序，我创建了一个 java 类

public class SavariMapActivityEventHandler extends EventHandler {
    private static SavariMapActivityEventHandler instance = null;

    @Override
    public void handleClick(Activity activity) {
        setActivity(activity);
        INITClick();
    }

    @Override
    public void INITClick() {
        getActivity().findViewById(R.id.endtrip).setOnClickListener(this);
        getActivity().findViewById(R.id.expensebutton).setOnClickListener(this);
        getActivity().findViewById(R.id.details).setOnClickListener(this);

    }

    private SavariMapActivityEventHandler() {


    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.endtrip:
            HandleEndTrip();
              break;

        }
    }

    private void HandleEndTrip() {
        AlertDialog alertDialog = new Builder(getActivity()).create();
        alertDialog.setTitle("Confirmation");
        alertDialog.setMessage("Has the trip ended?");
        alertDialog.setButton2("Cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                arg0.dismiss();
            }
        });
        alertDialog.setButton("Yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                try {
                    getActivity().endthread = true;
                    getActivity().getHandler().removeCallbacksAndMessages(null);
                    TimeCalculator calculator = new TimeCalculator(
                            getActivity(), System.currentTimeMillis(), holder
                                    .getStartfromGarageTime());
                    CustomerInfo.getInstance().setEndduration(
                            calculator.getHour());
                    getActivity().finish();
                    SavariMapActivityEventHandler.getInstance()
                            .finishActivity();
                    getActivity().startActivity(
                            new Intent(getActivity(),
                                    BillingConfirmActivity.class));

                }
                catch (Exception e)
                {
                    SavariUserSettings.appendLog("Savaari MapAcivityEventHandeler", ""+e+" "+e.getStackTrace()[0].getLineNumber());                 
                }
            }
        });

        alertDialog.show();

    }

    @Override
    public SavariMapActivity getActivity() {
        return (SavariMapActivity) super.getActivity();
    }

    public static SavariMapActivityEventHandler getInstance()
    {
        if (instance == null)
            instance = new SavariMapActivityEventHandler();
        return instance;
    }

    public static void setInstance(SavariMapActivityEventHandler instance) {
        SavariMapActivityEventHandler.instance = instance;
    }
}

事件处理程序代码：

    public abstract class EventHandler implements OnClickListener {
private ProgressDialog dialog;
public final String SETTINGS_PREFERENCE = "setting_pref";
private Activity activity;

public abstract void handleClick(Activity activity);

public abstract void INITClick();

public ValueHolder holder = null;

protected final void setActivity(Activity activity) {
    this.activity = activity;
    holder = new ValueHolder(activity);

}

public final void finishActivity() {
    activity.finish();
}

public final void INITDialog(String title, String mesg) {
    dialog = new ProgressDialog(activity);
    dialog.setTitle(title);
    dialog.setMessage(mesg);
    dialog.show();
}

public final void finishDialog() {
    try {
        if (dialog != null)
            dialog.dismiss();
        } catch (Exception e)
        {

        }
}

public Activity getActivity() {
    return activity;
}

}

在启动警报对话框之前检查活动是否完成

if(!isFinishing()){
   // create and show dialog
}
