Question

我已经制定法典,并努力实施这一法典:

class Example extends Dialog {
    @Override
    public void dismiss() {
        super.dismiss();
        if (isForceExists != false) {
            int id = android.os.Process.myPid();
            android.os.Process.killProcess(id);
        }
    }
}

但是,当我想在离开申请之前举行其他活动,而不是工作(小规模活动)。

class ExampleActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
       Example exDialog = new Example();
       exDialog.setDismissListener(new OnDismissListener() {
           AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
           builder.setTitle("Exit Application")
                 .setMessage("Thank you for using this application, happy nice day ^_^")
                 .show();
       });
    }
}

我想在申请退出之前放弃或等待进展,怎么做? 但是,在没有发生事前,这只是强迫离开?

====================================

谢谢你的建议。首先,我要对我的问题缺乏解释表示歉意。因此,我的详细问题是如何警惕。在完成(a)行动之前建立起来?

我想首先搁置警示,或处理这一事件。此外,还击退了Example Dialog。

@Override
public void onDismiss(DialogInterface dialog) {
    // --> I want to hold AlertDialog first, or handling this event.
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Exit Application")
            .setMessage("Thank you for using this application, happy nice day ^_^")
            .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface subDialog, int which) {
                    // --> And After show AlertDialog, back event to dismiss 
                    //     of Example extends Dialog again.
                    ExampleDialog.dismiss();
                }
            }).show();
}

Running AlertDialog, before finishing. And then return back to dismiss and exit application without from Activity class, but exit or finish from method s Example Dialog class.

class Example extends Dialog {
    public boolean isForceExists = true;
    @Override
    public void dismiss() {
        super.dismiss();
        if (isForceExists != false) {
            int id = android.os.Process.myPid();
            android.os.Process.killProcess(id);
        }
    }
}

您应处理贵方特类或独类行为本身的事件逻辑,而不是试图在显示方言时,在例常识方法范围内进行活动。

Modify your Example class to include a callback for the dismissal event:

class Example extends Dialog {
    private OnDismissListener dismissListener;

    public void setDismissListener(OnDismissListener listener) {
        this.dismissListener = listener;
    }

    @Override
    public void dismiss() {
        if (dismissListener != null) {
            dismissListener.onDismiss(this);
        }
        super.dismiss();
    }
}

Modify your ExampleActivity to implement the OnDismissListener interface and override its onDismiss method to execute your desired event before exiting the application:

import android.app.Activity;
import android.app.Dialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.widget.Toast;

public class ExampleActivity extends Activity implements DialogInterface.OnDismissListener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Example exDialog = new Example(this);
        exDialog.setDismissListener(this);
        exDialog.show();
    }

    @Override
    public void onDismiss(DialogInterface dialog) {
        // This method will be called before the dialog is dismissed.
        // You can perform your desired event here.
        // For example, showing a Toast message.
        Toast.makeText(this, "Before exit event executed.", Toast.LENGTH_SHORT).show();
        
        // After the event, you can exit the application if needed.
        finish();
    }
}

这种做法确保,在申请之前,当你辞退方言时,你的活动才会停止。
