从PopUpWindow越来越EDITTEXT输入 [英] getting editText input from PopUpWindow

问题描述

我不知道我怎么能拿从EDITTEXT框中输入一个popupwindow。我试过2种方式。一个具有布局充气，一个没有，但我要么得到或空，即使我输入的东西成箱

这其中一个返回了

  //获取用户名和密码输入
        查看inflatedView = getLayoutInflater（）膨胀（R.layout.login_popup，NULL）;
        的EditText usernameInput =（EditText上）inflatedView.findViewById（R.id.username_login_input）;
        的EditText passwordInput =（EditText上）inflatedView.findViewById（R.id.password_login_input）;        。最后弦乐usernameString = usernameInput.getText（）的toString（）;
        。最后弦乐passwordString = passwordInput.getText（）的toString（）;
 

这其中一个返回空值：

  //获取用户名和密码输入
        的EditText usernameInput =（EditText上）findViewById（R.id.username_login_input）;
        的EditText passwordInput =（EditText上）findViewById（R.id.password_login_input）;        。最后弦乐usernameString = usernameInput.getText（）的toString（）;
        。最后弦乐passwordString = passwordInput.getText（）的toString（）;
 

我想从其中无法从活动产生的login_popup.xml得到它

这是其中code是

修改

  LayoutInflater layoutInflater =
                 （LayoutInflater）getBaseContext（）getSystemService（LAYOUT_INFLATER_SERVICE）。
        查看popupView = layoutInflater.inflate（R.layout.login_popup，NULL）;
        PPW =新PopupWindow（popupView，LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT，真正的）;
        ViewGroup中parentLayout =（ViewGroup中）findViewById（R.id.title_page_layout）;
        //设置位置和弹出窗口的大小
        ppw.showAtLocation（parentLayout，Gravity.CENTER，10，20）;
 

解决方案

请尝试以下，而不是当您关闭弹出窗口：

 查看内容查看= ppw.getContentView（）;
的EditText usernameInput =（EditText上）contentView.findViewById（R.id.username_login_input）;
的EditText passwordInput =（EditText上）contentView.findViewById（R.id.password_login_input）;
。最后弦乐usernameString = usernameInput.getText（）的toString（）;
。最后弦乐passwordString = passwordInput.getText（）的toString（）;
 

我觉得你目前的做法是夸大新的观点，而不是从弹出的窗口中获取现有的意见。

I was wondering how I could get the input from an editText box in a popupwindow. I tried 2 ways. One with a layout inflator and one without but I either get "" or null even though i typed something into the box

This one returns the "" :

// get the username and password inputs
        View inflatedView = getLayoutInflater().inflate(R.layout.login_popup, null);
        EditText usernameInput = (EditText) inflatedView.findViewById(R.id.username_login_input);
        EditText passwordInput = (EditText) inflatedView.findViewById(R.id.password_login_input);

        final String usernameString = usernameInput.getText().toString();
        final String passwordString = passwordInput.getText().toString();

This one returns null :

// get the username and password inputs
        EditText usernameInput = (EditText) findViewById(R.id.username_login_input);
        EditText passwordInput = (EditText) findViewById(R.id.password_login_input);

        final String usernameString = usernameInput.getText().toString();
        final String passwordString = passwordInput.getText().toString();

I am trying to get it from login_popup.xml which is not generated from an activity

This is where the code is from

EDIT

LayoutInflater layoutInflater = 
                 (LayoutInflater) getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
        View popupView = layoutInflater.inflate(R.layout.login_popup, null);
        ppw = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true);
        ViewGroup parentLayout = (ViewGroup) findViewById(R.id.title_page_layout);
        // set the position and size of popup
        ppw.showAtLocation(parentLayout, Gravity.CENTER, 10, 20);

解决方案

Try the following instead when your popup window is closed:

View contentView = ppw.getContentView();
EditText usernameInput = (EditText) contentView.findViewById(R.id.username_login_input);
EditText passwordInput = (EditText) contentView.findViewById(R.id.password_login_input);
final String usernameString = usernameInput.getText().toString();
final String passwordString = passwordInput.getText().toString();

I think your current approach is inflating new views, rather than obtaining the existing views from the popup window.
