阅读更多关于 Restricting Android NumberPicker to Numeric Keyboard for Numeric Input (not Alpha keyboard)

问题 Is there a way to suggest or restrict keyboard input when selecting a NumberPicker so only the number controls are shown when entering values, similar to how you can use android:inputType="number" with a EditText? I have a series of values, from 0.0 to 100.0 in 0.1 increments that I'd like to be able to use a NumberPicker to select in Android 4.3. In order to have the numbers selectable, I've created an array of strings which corresponds to these values, as shown below: NumberPicker np =

WebView doesn't scroll when keyboard opened

阅读更多关于 WebView doesn't scroll when keyboard opened

问题 I have a WebView that contains an input form. When the user selects the first input the keyboard appears and will scroll the WebView so that the input is uncovered. My problem is in < API 19 when tapping on the next partially obscured input the WebView doesn't scroll. If I were to close the keyboard and then select the input it would scroll correctly. I've read a lot about if the Activity is FullScreen then it won't work but my app isn't. Manifest: <?xml version="1.0" encoding="utf-8"?>

阅读更多关于 SoftKeyboard does not display for a newly displayed Fragment

问题 I have a FragmentActivity that initially displays a fragment with a few buttons on it. When you click one of the buttons, the FragmentActivity displays a new fragment with some editText fields.

Keep soft keyboard open when enter key is pressed

阅读更多关于 Keep soft keyboard open when enter key is pressed

Well, I'm trying to prevent the soft keyboard from closing when the user press the "ok" button after editing a text field. Actually, what i'm trying to achieve is : when "ok" button is pressed, the field is parsed and if valid, it starts another activity. That is easy enough. But, when the field is not valid, I want the soft keyboard to stay open. And that's... a hell more complicated. If anyone know how to achieve such a thing... Thanks in advance. EDIT : what I mean by the OK button is the OK button from the soft keyboard. Attach OnEditorActionListener to your text field and return true from

How to show Android keyboard with symbols mode by default?

阅读更多关于 How to show Android keyboard with symbols mode by default?

I have a EditText component, and, of course, if you click on it, the Android keypad is shown, allowing the user to input text. As far as I know, all Android software keyboards have (at least) a letter mode ( ABC ) and a symbols mode ( ?123 ). Their default view is the letter mode. Now when the keypad is shown when the EditText component is clicked, I want the symbols mode to be shown by default. The user will still be able to switch to the letter mode. Is there a way to achieve that? If yes, how? Vikram I'm posting this because I don't think any of the answers actually address the question.
