How to make visible the click action on Button? - android

When we click the Button,the background change color to some black transparent color. But, when I change the background of Button, the user can't see the visual reaction of Button when he click on them.
Thank you for your help.

For v21 and above you can use:
bg_button.xml
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?android:colorControlHighlight">
<item android:drawable="#drawable/button_normal" />
</ripple>
In your Button:
<Button
...
android:background="#drawable/bg_button" />
Important: if button has disable state ripple effect not shows.

Change Tint Image Button after pressed

I am trying to create an ImageButton able to change the icon color after pressing. I want to do that in my XML file. I have the following code:
...
<ImageButton
android:id="#+id/stop_button"
android:layout_width="0dp"
android:layout_height="0dp"
android:src="#drawable/stop_icon"
android:background="#drawable/stop_button"
android:tint="#color/ship_cove"
app:layout_constraintBottom_toTopOf="#id/bottom_icon_guideline"
app:layout_constraintLeft_toRightOf="#id/start_icon_guideline"
app:layout_constraintRight_toLeftOf="#id/end_icon_guideline"
app:layout_constraintTop_toBottomOf="#id/mediatop_icon_guideline" />
And here is my #drawable/stop_button.xml file content:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/cornflower_blue">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/oxford_blue" />
<corners android:radius="8dp" />
</shape>
</item>
</ripple>
As I stated before, my purpose is to change my stop_icon tint after pressing my stop_button, but I do not know how I can do that. Can anyone help me?
Note: if my button is not pressed, I want my stop_icon with the color #color/ship_cove. If it is, I want the color #color/mirage.
Instead of color create a color selector with a pressed state.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:color="pressed_color" android:state_pressed="true" />
<item android:color="default_color" />
</selector>
And use this selector for the color of the icon. The rest should be taken by the system.

Android ripple background color

I am using a ripple effect on my navigation drawer. I have set it like this and applied it to my ListView:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_activated="true" android:drawable="#color/black_200" />
<item android:state_pressed="true" android:color="#color/black_200">
<ripple android:color="#color/black_400" />
</item>
<item android:drawable="#color/white" />
</selector>
I want the ripple background to remain the same like the normal activated state. Even when I define the color to be the same as the activated state, it gets darker and the ripple bubble gets even more dark. How can I color the background to be the same like the activated state and the ripple bubble to be the color I told it to be?
It's a lot easier to do with styles:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
...
<item name="colorControlHighlight">#color/ripple_material_dark</item>
...
</style>
You can control the colour of the RippleDrawable by doing the following:
RippleDrawable rippleDrawable = (RippleDrawable)view.getBackground(); // assumes bg is a RippleDrawable
int[][] states = new int[][] { new int[] { android.R.attr.state_enabled} };
int[] colors = new int[] { Color.BLUE }; // sets the ripple color to blue
ColorStateList colorStateList = new ColorStateList(states, colors);
rippleDrawable.setColor(colorStateList);
Or, via XML:
<?xml version="1.0" encoding="utf-8"?>
<ripple
xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#FFFF0000"> <!-- The ripple will be red -->
<!-- the normal bg color will be light grey -->
<item>
<color android:color="#FFDDDDDD" />
</item>
<!-- make sure the ripple doesn't exceed the bounds -->
<item android:id="#android:id/mask">
<shape android:shape="rectangle">
<solid android:color="?android:colorAccent" />
</shape>
</item>
</ripple>
EDIT
After seeing #i.shadrin's answer below, I must admit it's a much simpler approach (using styles). If this is an option for you, I would recommend it.
add these two line of code inside of your view to give ripple effect .
android:clickable="true"
android:background="?attr/selectableItemBackground"
If you are using the custom button color then use below code for ripple effect.
Save the file in drawable with name my_ripple.xml
and set in background of button.
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:color="#color/ripple_color"
tools:targetApi="lollipop">
<item android:id="#android:id/mask">
<shape android:shape="rectangle">
<solid android:color="#color/ripple_color"
/>
</shape>
</item>
<item
android:id="#android:id/background"
android:drawable="#color/button_color" />
</ripple>
An example ripple to use with a selector on api lvl 21 and above
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?attr/colorControlHighlight">
<!-- ripple mask -->
<item android:id="#+id/mask">
<color android:color="#android:color/white"/>
</item>
<!-- background shape or color -->
<item android:drawable="#drawable/rectangle_rounded_steel_blue"/>
</ripple>

android checkbox text disappears when custom background is set

I want to make a weekly calendar, where every day is a custom checkbox with objective to look like the image bellow:
(http://i.imgur.com/WjIKCd0.png)
When the user clicks on a day (Monday in this case), the "background" and "button" checkbox changes as well the text color...
I made the drawables and it seems to work fine... check bellow the code:
Checkbox layout:
<CheckBox
android:id="#+id/selectMonday"
android:layout_width="40dp"
android:layout_height="40dp"
android:button="#drawable/ic_none"
style="#style/CheckBoxBackgroundView"
android:onClick="selectDay"
android:text="#string/monday_letter"
android:gravity="center"
android:checked="true"/>
(the drawable "ic_none", is simple a 135x135 "transparent" image with nothing in it...)
Style (CheckBoxBackgroundView):
<style name="CheckBoxBackgroundView">
<item name="android:background">#drawable/background_day_week_picker_box_selector</item>
<item name="android:textColor">#color/text_color_day_week_picker_box_selector</item>
<item name="android:textSize">#dimen/text_spinner_text</item>
<item name="android:textStyle">bold</item>
</style>
Background Selector (background_day_week_picker_box_selector):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="false"
android:drawable="#drawable/background_day_of_week_picker_unselected" />
<item android:state_checked="true"
android:drawable="#drawable/background_day_of_week_picker_selected" />
</selector>
Background selected (background_day_of_week_picker_selected):
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<!-- view background color -->
<solid
android:color="#color/red_color" >
</solid>
<!-- view border color and width -->
<stroke
android:width="3dp"
android:color="#color/transparent">
</stroke>
<!-- Here is the corner radius -->
<corners
android:radius="10dp" >
</corners>
</shape>
and finally the color selector (text_color_day_week_picker_box_selector):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="false"
android:color="#color/red_color"></item>
<item android:state_checked="true"
android:color="#color/white"></item>
</selector>
I tried this in several devices... in some, it appears like it suppose to, in others the text disappears and it looks like this:
(http://i.imgur.com/Jy9FrPS.png)
probably is coincidence, but all the devices that worked are below 5 inches...
is there anything wrong with my code that I'm not seeing? anyone have any suggestions?
Thanks in advance
The problem is that the 135x135 button drawable is pushing the text out of the bounds of your CheckBox's width. Instead of using a drawable, you can just set android:button="#color/transparent".

How can i make an "Gmail" like header buttons? (Pic attached)

Does any one knows how can i skin an android button to look like this:

Thanks in advance,

The following layout files will product a button with 5px radius, of course u input your own color and change the solid color to gradient to match ur screenshots, then on the button change the text colour to white or something.. I dont have time for examples now.. good luck though.
and lastly you have to apply them as background to your button like this
<Button
android:id="#+id/btnLoveThisOne"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp"
android:text="Love me love u too!"
android:background="#drawable/button_background" <!-- Yes look at me -->
/>
button_background_normal.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/button_background_normal_color"/> <!-- Change this to your own colour -->
<corners android:radius="5px"/>
<stroke android:width="1dp" android:color="#20ffffff"/>
</shape>
button_background_pressed.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/button_background_pressed_color"/> <!-- Change this to your own colour -->
<corners android:radius="5px"/>
</shape>
button_background.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true"
android:state_pressed="false"
android:drawable="#drawable/button_background_normal" />
<item android:state_focused="true"
android:state_pressed="true"
android:drawable="#drawable/button_background_pressed" />
<item android:state_focused="false"
android:state_pressed="true"
android:drawable="#drawable/button_background_pressed" />
<item android:drawable="#drawable/button_background_normal" />
</selector>
I know two ways to make it:
a Button or TextView with an image having that engraving rectangle, for stretch, use 9.patch :)
a Button or TextView with transparent background and a selector drawing the shape border
However, I don't know exactly how they did as shown in your picture.

How to change the background color of the toggle button on Android

I tried to change the background color of the toggle button using XML file as white color, but the toggle button is totally damaged. It looks like all the button was covered with white.
There is no indication of ON or OFF on the toggle button when I have changed the color of the toggle button to white. Is there is another way to change the background which will not damage the indication of the toggle button?
<ToggleButton android:id="#+id/togglebutton"
android:layout_width="100px"
android:layout_height="46px"
android:background="#ffffff"
android:layout_above ="#+id/save"
android:textOn="DAY"
android:textOff="NIGHT" />
This is how my XML code look for the toggle button.
Yes, there is a way to change the background as you wish, but you have to use a selector like this as background:
<selector
xmlns:android="http://schemas.android.com/apk/res/android"
>
<item
android:state_focused="true"
android:state_pressed="false"
android:drawable="#drawable/some_image" />
<item
android:state_focused="true"
android:state_pressed="true"
android:drawable="#drawable/some_other_image" />
<item
android:state_focused="false"
android:state_pressed="false"
android:drawable="#drawable/some_image1" />
<item
android:state_focused="false"
android:state_pressed="true"
android:drawable="#drawable/other_image" />
</selector>
For #Drawable, etc. (you can use a color or make a gradient. Check this for more information about gradients.
Follow this way to make your ToogleButton have background color red when On and green when OFF
First, create tooglebutton_selector.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/togglebutton_on"
android:state_checked="true" />
<item android:drawable="#drawable/togglebutton_off"
android:state_checked="false"
/>
</selector>
Second, create togglebutton_on.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
android:color="#ff0000" /> // red color
</shape>
Third, create togglebutton_off.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
android:color="#00FF00" /> // green color
</shape>
Finally, in your ToggleButton
<ToggleButton
android:id="#+id/btnMon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/tooglebutton_selector" //set background of ToggleButton to tooglebutton_selector
/>
When you decompile your SystemUI.apk, you should go to the following file: SystemUI/res/values/colors.xml
Then change the following line:
#ff000000
#ffffffff
#80000000
#ffadc1d6
#ffffffff
#ffe6e6e6
