在显示确认关闭应用程序的对话框时，我被以下问题困扰。该应用程序可以正常关闭，但在logcat中整个页面都是红色的。我已经通过网络进行了研究，有人说应该创建正在显示的对话框。

代码：

@Override
    public void onBackPressed() 
    {
        final Dialog dialog1 = new Dialog(First.this, android.R.style.Theme_Translucent_NoTitleBar);


        dialog1.setContentView(R.layout.alert_dialog_quit_with_email);
        dialog1.setCancelable(true);
        dialog1.show();  // LINE 323

        TextView thankyou = (TextView) dialog1.findViewById(R.id.thankyou);
        TextView Title_V1 = (TextView) dialog1.findViewById(R.id.Title_V1);
        Button alert_cancel = (Button) dialog1.findViewById(R.id.button_cancel);
        Button alert_quit = (Button) dialog1.findViewById(R.id.button_ok);
        Button button_email = (Button) dialog1.findViewById(R.id.button_emailll);

alert_cancel.setOnClickListener(new OnClickListener() 
        {
            public void onClick(View v) 
            {
                dialog1.dismiss();
                return;
            }
        });

        alert_quit.setOnClickListener(new OnClickListener() 
        {
            public void onClick(View v) 
            {
                First.this.finish();
            }
        });

        button_email.setOnClickListener(new OnClickListener() 
        {
            public void onClick(View v) 
            {
                View view1 = getLayoutInflater().inflate(R.layout.first, null);
                button_Email_click(view1);
            }
        });
    }

问题：

我试图写为，dialog1.create().show();但它随后用红色下划线表示.create()并将其描述为The method create() is undefined for the type Dialog。

我发现红色的logcat只会在按下退出按钮时出现......是因为它会显示一个对话框但活动已关闭吗？我已经声明了 dialog1...如何修改？谢谢！

在这两种方法中也关闭你的对话框，就像这样

 alert_quit.setOnClickListener(new OnClickListener() 
        {
            public void onClick(View v) 
            {

                  First.this.finish();
                  dialog1.dismiss();

            }
        });

        button_email.setOnClickListener(new OnClickListener() 
        {
            public void onClick(View v) 
            {
                View view1 = getLayoutInflater().inflate(R.layout.first, null);
                button_Email_click(view1);
                dialog1.dismiss();
            }
        });

我认为您应该添加View.到您的onClickListeners, 和Override它们中。

前任。

alert_cancel.setOnClickListener(new View.OnClickListener() 
        {
            @Override
            public void onClick(View v) 
            {
                dialog1.dismiss();
                return;
            }
        });

在 onKeyDown 而不是 onBackPressed 中尝试相同的操作。

       @Override
        public boolean onKeyDown(int keyCode, KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_BACK) {
                // Your code
            }
            return super.onKeyDown(keyCode, event);
        }

你也可以试试dialog1.cancel()。基本上问题可能是因为对话框没有被取消或关闭，所以它泄漏了。
