EditText getHint() returns null when using design support library

阅读更多关于 EditText getHint() returns null when using design support library

问题 When using EditText in combination with Design lib's (ver 22.2.1) TextInputLayout getting hint programmatically returns null. I'm trying to append asterisk '*' to a mandatory field programmatically, hence EditText.getHint() but the fact that it returns null is an issue in this case. EditText editText = (EditText) findViewById(R.id.edit2); String hint = String.format("%s *", editText.getHint()); editText.setHint(hint); A simple code illustration: Layout.xml: <android.support.design.widget

阅读更多关于 How to create an interface to get info from a Fragment to an Android Activity?

Over the past days I've desperately been trying to build an android app with a simple fragment (which I use twice). I want to pass the contents of the fragments' EditText-boxes to a new activity. I just can't figure out how to get those contents from the fragments. What I have so far is this: I've got my edit_text_fragment.xml : <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <EditText android:id="@+id/my_edit_text" android

What's the right way to extend EditText to give it additional “default” functionality

阅读更多关于 What's the right way to extend EditText to give it additional “default” functionality

问题 I'm wondering if it's possible to add functionality to EditText such that when I include my newly extended field in the layout xml, I don't have to then add any code to the Activity class to get it to behave in specific ways. For example, I'd like to make a EditPhone field which is just an EditText that has the added feature of listening for key events and modifying the field to include parenthesis and dashes in their appropriate locations. At the moment, I'm always having to include the

Why my EditText copy/paste menu is under the EditText? How change the z-order of popup window?

阅读更多关于 Why my EditText copy/paste menu is under the EditText? How change the z-order of popup window?

问题 NOTE If someone know how to order (z-order) Windows added via windowmanager, i will also accept the answer because it's will answer all the question. Actually i only find to do windowManager.removeView(MyView) following immediatly by windowManager.addView(MyView) to put a view in front of the other, but this is not ideal because it's visually remove and add the view. it's look crazy that their is no build in function in android to do such a simple think. I create a view (linearlayout) that

阅读更多关于 How to customize the “chips” auto-suggesting mechanism, as used on Gmail's recipients field?

问题 Background I've searched for a way to have a similar look & feel to the Gmail receipients field, which allows auto-filling of items in a really cool way: The class that is built into the Android framework and is responsible for this is called "MultiAutoCompleteTextView" . The problem the MultiAutoCompleteTextView is quite basic, yet it doesn't hold enough samples, tutorials and libraries to get to know how to customize it like on Gmail and the likes. I would like to know how to customize it

阅读更多关于 Android EditText: Done instead of Enter or Word Wrap instead of Multi Line

问题 I have a multiple line EditText that does not permit line returns. Right now I am replacing returns with some spaces as soon as they click save. Is there any way I can replace the on screen enter button with a Done button? (like it is for single line EditText) I am aware that I should still strip out returns ( \r\n|\r|\n ) because the on screen keyboard is not the only way to add them. Here is my current XML <EditText android:layout_width="fill_parent" android:layout_height="wrap_content"
