SwitchCompatNotify is not getting string from strings.xml resource in text property

I'm trying to do the following:
<com.ophiropt.meissa.view.SwitchCompatNotify
android:id="#+id/trigger_switch_channel_b"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:checked="false"
android:text="#{#string/channel+ #string/b}"
android:textColor="?attr/colorPrimary"
android:textSize="18sp"/>
but I don't see any text near the switch if I write a "hard-coded" text like:
android:text="channel a"
I see the text near the switch without any problem,
is this a bug of Android?
how can I get it to work?
(I can't put there a hard-coded word because I need it to be translated to 5 languages )
any idea?
Thanks!!

the problem wasn't with the SwitchCompatNotify by the end,
the problem was with the inflating of the dialog that contained it.
we can have a text like this: android:text="#{#string/channel+ #string/b}"
only if the dialod is using data binding,
and in this case the inflate of the dialog was a regular one without using data binding(DataBindingUtil.inflate), therefore it didn't work.

How do I write a fraction in android studio

How to do I write a fraction in android studio. What's the best practice for a fraction with a horizontal line I am trying to produce.

Use html format. However you must add a extra space on the top and bottom to keep it from being cut off.
SpannableStringBuilder test = new SpannableStringBuilder();
test.append("\n");
test.append(Html.fromHtml("<sup>5</sup>/<sub>9</sub>"));
test.append("\n");

You can try this solution: http://blog.sqisland.com/2014/11/android-stacked-fractions.html
Basically, you have to looking for a font that supports afrc. Now, you can play with your TextViews and TagHandlers until you get the result desired.

The solution does not seem simple, however if you want to try fraction in xml, go to this website.
http://unicode-search.net/unicode-namesearch.pl?term=fraction
This code worked for me to show 1⁄4.
The xml code is.
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="\u00BC"
android:id="#+id/textView"
android:textSize="25sp" />
The required line is android:text="\u00BC" to show 1⁄4 as fraction.
So if you want to show 1⁄2 or any other as fraction from the above mentioned website, just append the last two characters(in this case BD) to \u00.
So 1/2 becomes \u00BD

disable "spell checking" on textView

This is more a 'is there a more appropriate way' question as I have found a work around.
Some of my table headers are being picked up as spelling errors and underlined in red. Of course, that is not what I would like to see. I have found that using
android:inputType="textNoSuggestions"
does disable the spell check markings. I find it odd (bug?) that this is necessary as the docs state:
inputType: The type of data being placed in a text field, used to help
an input method decide how to let the user enter text.
and there is no input associated with just textView. So is this the only/more appropriate way of avoiding the spell check and also, is this a bug that it is spell checking non-input fields?
UPDATE: per request this is sample xml
<TextView
android:text="ID#"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:typeface="monospace"
android:textSize="14sp"
android:digits="4"
android:textAlignment="gravity"
android:layout_weight="5"
android:gravity="left"
android:singleLine="true"
android:phoneNumber="true"
android:inputType="textNoSuggestions|none">
</TextView>

First, I would try removing the android:digits, android:phoneNumber, and android:inputType attributes.
All of those are more intended for use with fields that allow input (such as EditTexts). It also doesn't look like you are using the android:digits attribute correctly, as the string you provide defines the only allowable characters.
In essence, this combination of attributes is telling Android that your TextView accepts input in the form of telephone numbers that contain only the number 4, that this TextView doesn't accept input of any type, and Android should not provide spellcheck suggestions.
If you are setting the content of the TextView yourself, there really is no reason to try to restrict the content of the TextView with flags such as android:phoneNumber since you are the one controlling that.

I know this is an old thread but removing the following from content XML worked for me:
android:autoText="true"

On later android studio versions try:
android:autoText="true"
inside of the (or any input) in the xml.
On newer versions try:
android:inputType="textNoSuggestions"

Meaning of "No label views point to this text field" warning message

What is the meaning of this warning?
No label views point to this text field with an android:labelFor="#
id/# id/editText1" attribute
Note that the double id (#id/#id) is a problem with the error message text and does not reflect the XML content (which is the correct syntax).

The labelFor is an attribute for accessibility options. You assign this to a label so that if, on a form , user clicks a textedit field , android can know what to read (TalkBack) to user.
The id you assigned to it doesn't seem to be a valid one. why there are two #id in the id? Use ids like this: #id/editText1

I've had the same warning message. It disappeared, when I added a hint to my EditText
android:hint="Some explanation about the input..."

Although I am not familiar with the exact error you have posted. But it definitely sounds like you have done something wrong with the id in the textView. Use id like following in your textView.
android:id="#+id/editText1"
And if you want to set labelFor then use :
android:labelFor="#+id/editText1"

It means that you probably should define a label for this edit text and link them using a labelFor inside that labels definition.
example code:
<TextView
android:id="#+id/my_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:labelFor="#+id/my_editText" <!--the plus sign goes first in the code-->
android:text="I'm a label" />
<EditText
android:id="#id/my_editText" <!--no plus sign if not the first-->
android:layout_width="wrap_content"
android:inputType="text"
android:layout_height="wrap_content" />
and it's not only for text views.

Remove th first '#id/' , use like
android:id="#+id/editText1"
which is the correct format. Keep going.. Best wishes.. :)

I solved it by writing both attributes:
android:id="#+id/editText1"
android:labelFor="#+id/editText1"

Select the editText, go to Properties, then Label for and enter #id/EditText1

If the XML looks correct and you're in a Graphical Layout mode then it's probably using a later version of the Android rendering layout that doesn't support EditText.
In Eclipse and Android Studio there should be a green Android icon with what API version is rendering the layout. Make sure you're using a non W or Wearable API as Android W APIs don't support the EditText element. (EditText is most likely not supported because virtual keyboard space is limited on those devices).
The rendered preview should support EditText in any API 4.X version without a trailing W.

android changing text view (is this code ok?)

Can some one help me, I have heard alot of things and I dont know what to believe. I am making an app that is a counter. In my xml layout i have a TextView acting as a counter and the text is set by a string in strings.xml and i am controlling what the text view says from my java file. here is some code snip its. all I want to know is this ok?, it works fine but I want to know is it a bad or good way.
"counter" equals a variable.
"display" is referencing the ID of the textview"
what i am using to control the text view.
display.setText(String.valueOf(counter));
here is my text view in my xml layout
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/tvDisplay"
android:gravity="center"
android:text="#string/counter"
android:textSize="20dp" />
here is the string in strings.xml
<string name="counter">0</string>

It's fine, that's how you change text dynamically.

Yes, All things are right and good. Yo should have to give the String Value as like that.
If there is a Small Value of TextView then you can directly give as android:text="abcd"
And If you want to give any reference of that then your code is also correct and works as well.
For the Best use of coading your should have to try as like you have done rightnow. as Because it helps you a lot if there are number of TextView and you want to manage or change the Value of it quickly.
Enjoy. :)
Thanks.
