Angular/Material Mat-form-field Input - Floating Label Issues


Answer :

assuming you are using latest stable version of material 2,
you can use floatLabel="never" to force label to not to float.

here is live working demo

this is clear in documentation https://material.angular.io/components/form-field/api


<form class="search-form">   <mat-form-field class="example-full-width" appearance="standard">     <input class="toolbar-search" type="text" matInput>     <mat-placeholder>Search</mat-placeholder>   <mat-icon matSuffix style="font-size: 1.2em">search</mat-icon>   </mat-form-field> </form>

Please set the appearance of mat-form-field to standard and the placeholder will stop behaving like label.

Explanation : By default the mat-label in mat-form-field floats and the appearance of mat-form-field is "legacy". That means if a mat-label is not present with the form field then placeholder will start behaving like the label and it floats upwards. So to stop this you should manually update the appearance to "standard", so it stops behaving like label and stays as a placeholder.


Praveen Soni's answer above doesn't work for non-legacy versions, as per this:

Note: only the legacy appearance supports the never option. never was originally added as a way to make the floating label emulate the behavior of a standard input placeholder. However the form field now supports both floating labels and placeholders. Therefore in the non-legacy appearances the never option has been disabled in favor of just using the placeholder.

That means you should simply use placeholder instead of the label.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
