Question

在显示确认关闭应用程序的对话框时，我被以下内容所困扰。该应用程序可以正常关闭，但在logcat整个页面是红色的。我已经通过网络进行了研究，有些人说应该创建对话框。

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);
            }
        });
    }

logcat的：

问题：

我尝试写为dialog1.create().show();但是它会以.create()的红色加下划线并将其描述为The method create() is undefined for the type Dialog。

我发现红色logcat只会在按下退出按钮时出现...是不是因为它会显示一个对话框，但活动已关闭？我已经宣布了dialog1 ......如何修改它？谢谢！

Answer 1

也可以在这两种方法中关闭对话框，例如

 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();
            }
        });

Answer 2

我认为您应该将View.添加到onClickListeners和Override。

离。

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

Answer 3

在onKeyDown中尝试相同而不是onBackPressed。

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

Answer 4

您也可以尝试dialog1.cancel()。基本上问题可能是因为对话框没有被取消或被解雇，它就会泄漏。

Android对话框正在泄露窗口＆＃34;
