Android Button With Rounded Corners, Ripple Effect And No Shadow


Answer :

I finally solved it with below code. This achieve rounded corners for button. Also, for Android Version >= V21, it uses ripple effect. For earlier Android version, button color changes when it is clicked, based on android:state_pressed, android:state_focused, etc.

In layout xml file:

<Button     style="?android:attr/borderlessButtonStyle"     android:id="@+id/buy_button"     android:layout_width="0dp"     android:layout_weight="1"     android:layout_height="match_parent"     android:gravity="center"     android:background="@drawable/green_trading_button_effect"     android:textColor="@android:color/white"     android:text="BUY" />

For button onclick ripple effect (Android >= v21) :

drawable-v21/green_trading_button_effect.xml

<?xml version="1.0" encoding="utf-8"?> <ripple xmlns:android="http://schemas.android.com/apk/res/android"     android:color="@color/ripple_material_dark">      <item android:id="@android:id/mask">         <shape android:shape="rectangle">             <solid android:color="@android:color/white" />             <corners android:radius="5dp" />         </shape>     </item>      <item android:drawable="@drawable/green_trading_button" /> </ripple>

For earlier Android version, just change background color during onclick:

drawable/green_trading_button_effect.xml

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:state_pressed="true" android:drawable="@drawable/green_trading_button_selected" />     <item android:state_focused="true" android:drawable="@drawable/green_trading_button_selected" />     <item android:state_selected="true" android:drawable="@drawable/green_trading_button_selected" />     <item android:drawable="@drawable/green_trading_button" /> </selector>

drawable/green_trading_button.xml

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="rectangle">      <solid android:color="#ffa6c575"/>     <!-- rounded corners -->     <corners android:radius="5dp" /> </shape>

drawable/green_trading_button_selected.xml

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="rectangle">      <solid android:color="#ffc5dca8"/>     <!-- corners corners -->     <corners android:radius="5dp" /> </shape>

drawable/ripple_circle.xml

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:drawable="@drawable/circle" android:state_pressed="true">         <shape android:shape="rectangle">             <corners android:bottomLeftRadius="25dp" android:bottomRightRadius="25dp" android:topLeftRadius="25dp" android:topRightRadius="25dp" />         </shape>     </item>     <item android:drawable="@android:color/transparent" /> </selector>

drawablev21/ripple_circle.xml

<?xml version="1.0" encoding="utf-8"?> <ripple xmlns:android="http://schemas.android.com/apk/res/android"     android:color="@color/ripple_white">     <item android:id="@android:id/mask">         <shape android:shape="rectangle">             <corners                 android:bottomLeftRadius="25dp"                 android:bottomRightRadius="25dp"                 android:topLeftRadius="25dp"                 android:topRightRadius="25dp" />             <solid android:color="?android:colorAccent" />         </shape>     </item> </ripple>

drawable/button_circle_background.xml

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="rectangle">     <corners         android:bottomRightRadius="25dp"         android:topRightRadius="25dp"         android:bottomLeftRadius="25dp"         android:topLeftRadius="25dp"/>     <solid android:color="@color/colorAccent" /> </shape>

drawable/circle.xml

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="rectangle">     <corners         android:bottomRightRadius="25dp"         android:topRightRadius="25dp"         android:bottomLeftRadius="25dp"         android:topLeftRadius="25dp"/>     <solid android:color="@color/ripple_white" /> </shape>

Setting style and ripple to Button

<Button             android:id="@+id/choose_folder"             style="@style/Base.Widget.AppCompat.Button.Borderless"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_margin="8dp"             android:background="@drawable/button_circle_background"             android:foreground="@drawable/ripple_circle"             android:text="Chose Folder"             android:textColor="@android:color/white" />

Try setting this in your xml. This worked for me. 

style="?android:attr/borderlessButtonStyle"

Also, if you are targeting API level 21 and above you can use 

android:stateListAnimator="@null"

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.
