Android Image Scale Animation Relative To Center Point


Answer :

50% is center of animated view.

50%p is center of parent

<scale     android:fromXScale="1.0"     android:toXScale="1.2"     android:fromYScale="1.0"     android:toYScale="1.2"     android:pivotX="50%"     android:pivotY="50%"     android:duration="175"/>

The answer provided by @stevanveltema and @JiangQi are perfect but if you want scaling using code, then you can use my answer.

// first 0f, 1f mean scaling from X-axis to X-axis, meaning scaling from 0-100% // first 0f, 1f mean scaling from Y-axis to Y-axis, meaning scaling from 0-100% // The two 0.5f mean animation will start from 50% of X-axis & 50% of Y-axis, i.e. from center  ScaleAnimation fade_in =  new ScaleAnimation(0f, 1f, 0f, 1f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); fade_in.setDuration(1000);     // animation duration in milliseconds fade_in.setFillAfter(true);    // If fillAfter is true, the transformation that this animation performed will persist when it is finished. view.startAnimation(fade_in);

Forget the additional translation, set android:pivotX, android:pivotY to half the width and height and it will scale from the center of the image.

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.
