问题 What's wrong with this code? I want to use id automatically. I think after R.string there is a mistake. What can ı do 回答1: Do it like this public static int getStringIDFromName(String stringName) { int stringID= 0; if(stringName == null || stringName.equalsIgnoreCase("")) { return 0; } try { @SuppressWarnings("rawtypes") Class res = R.string.class; Field field = res.getField(stringName); stringID = field.getInt(null); } catch(Exception e) { // Error } return stringID; } Set your value like

How can a textfield from fxml file be updated by setText in java file?

问题 I am looking to update text in a textfield based on some value. In order to make this sample simpler I have made my program smaller. The problem seems to be when I put top.setText("This is my new Text"); I looked at this: how to change the text of TextField in java fx 2 but the answer does not seem to make sense. I don't know why you'd initialize a textfield that has already been implemented. Regardless it did not work. I have also looked at: NullPointerException (JavaFX Label.setText()) This

JTextField's setText method doesn't work from a KeyListener

由 落爺英雄遲暮 提交于 2019-12-07 21:50:51
问题 I'm puzzled as to why a JTextField doesn't seem to just "clear out" by using the setText("") method on it, when this is coming from a KeyListener. It works fine from an ActionListener, except that, most amazingly, if the KeyListener method tries to invoke the ActionListener method, with a dummy action event (created on the fly as a simple test), it still leaves the typed text in place. In other words, when you run it from the command line, if you type, for example, a "3" into the field, you

setText doesn't set text to EditText

问题 I'm having a problem that I've never had before in almost three years of developing with Android... I want to take a picture and after the picture is taked, the EditText s of the activity become clear. What I'm doing is set the values of the EditText to Strings using getText().toString() to restore them after taking the picture. The strings are stored perfectly with the data, but when I use setText , it doesn't work... The strange thing is that setHint works! How can it be? Here's the code I

Updating a textview inside a custom dialog via a button

由 こ雲淡風輕ζ 提交于 2019-12-05 11:01:37
问题 So, my current issue is that I can't find an elegant way to update a dialog box when a button is pressed. I can achieve functionally the same result by dismiss() and show(), but that is ugly. Lets say this dialog has 3 buttons, for selling widgets that the player has. Sell All, Sell 10, and Sell X (amount entered with a EditText). I'd like for the dialog to persist if the player pushes Sell 10, but also to update it's textviews with the new count of widgets. Pertinent part of the XML layout
