如何暂停代码以获取来自AlertDialog的结果

public interface AlertDialogListener {
    void onResult(boolean result);
}

public class MainActivity extends AppCompatActivity implements AlertDialogListener {

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

        // 弹出AlertDialog
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("提示");
        builder.setMessage("是否继续操作？");
        builder.setPositiveButton("是", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 调用回调方法，传递结果为true
                onResult(true);
            }
        });
        builder.setNegativeButton("否", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 调用回调方法，传递结果为false
                onResult(false);
            }
        });
        builder.show();
    }

    @Override
    public void onResult(boolean result) {
        // 处理AlertDialog的结果
        if (result) {
            // 用户选择了"是"
            // 继续操作
        } else {

            // 取消操作
        }
    }
}
