java - Activity 泄漏了最初添加到此处的窗口(当登录数据错误时)

Question

当用户输入错误的密码时(如果不成功)，我在 Android 应用程序的登录 Activity 中遇到错误。显示用户输入错误密码(例如)时的错误，但也会显示调试期间的错误。不知道为什么。

错误:

E/WindowManager: android.view.WindowLeaked: Activity de.myfirstapp.app.LoginActivity has leaked window DecorView@a5b0d96[] that was originally added here

我的重要代码:

Response.Listener<String> responseListener = new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        try {
            JSONObject jsonResponse = new JSONObject(response);
            boolean success = jsonResponse.getBoolean("success");
            if (success) {
                String displayName = jsonResponse.getString("display_name");

                Intent intent = new Intent(LoginActivity.this, UserAreaActivity.class);
                intent.putExtra("displayName", displayName);

                LoginActivity.this.startActivity(intent);
            } else {
                AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
                builder.setMessage("Login informations are wrong. Please check email and password")
                        .setNegativeButton("Retry", null)
                        .create()
                        .show();
            }
        } catch (JSONException e) {
            e.printStackTrace();
            AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
            builder.setMessage("Webspace is currently not reachable.")
                    .setNegativeButton("Ok", null)
                    .create()
                    .show();
        }
    }
};

谢谢你帮助我:)

在 Dialog 上调用关闭:

    } else {
            AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
            builder.setMessage("Login informations are wrong. Please check email and password")
            .setNegativeButton("Retry",new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int id) {
            //retry or dialog.dismiss();
            }
            })
            .create()
            .show();

        }
    } catch (JSONException e) {
        e.printStackTrace();
        AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
        builder.setMessage("Webspace is currently not reachable.")
        .setNegativeButton("Ok", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {
         dialog.dismiss();
        }
        })
        .create()
        .show();
     }
