how to get background button with selector in drawable folder?
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/btn_press" android:state_pressed="true"></item>
<item android:drawable="#drawable/btn_mati" android:state_selected="false"></item>
</selector>
try like this,
Create button_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/btn_hover" android:state_pressed="true"></item>
<item android:drawable="#drawable/btn_hover" android:state_focused="true"></item>
<item android:drawable="#drawable/btn_normal" android:state_enabled="true" android:state_focused="false" android:state_pressed="false"></item>
<item android:drawable="#drawable/btn_hover" android:state_enabled="false"></item>
</selector>
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/button_selector"
/>
in your java class,
btn.setBackgroundResource(R.drawable.button_selector);

temp_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#color/color1" />
<item android:state_selected="true" android:color="#color/color2" />
<item android:color="#color/color3" />
</selector>
And I applied it through the code below
imageView.setImageResource(R.drawable.image)
ImageViewCompat.setImageTintList(imageView, ColorStateList.valueOf(R.color.temp_selector))
I don't know why it doesn't work... What should I do?
(It has to be applied programatically. not xml.)
Use below to change color
imageView.isSelected = true
imageView.isSelected = false
Use below selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/color3" android:state_selected="false" />
<item android:color="#color/color2" android:state_selected="true"/>
<item android:color="#color/color1" android:state_pressed="true" />
</selector>
Is there a way to change the color of a disabled button in android through styles or some other form ?
I currently have the following,
drawable/button_default.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/button_default_shape"/>
</selector>
drawable/button_default_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/button_default_background"/>
<corners android:radius="3dp"/>
</shape>
values/styles.xml
<style name="AppTheme.Button">
<item name="android:background">#drawable/button_default</item>
<item name="android:textColor">#android:color/white</item>
<item name="android:textAllCaps">false</item>
<item name="android:paddingTop">10dp</item>
<item name="android:paddingBottom">10dp</item>
<item name="android:focusable">true</item>
<item name="android:clickable">true</item>
<item name="android:gravity">center</item>
<item name="android:textStyle">bold</item>
<item name="android:textSize">17sp</item>
<item name="android:textAppearance">#style/CustomFontAppearance</item>
</style>
You'll have to use a selector for different drawables in those states.
You can create a selector like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/your_enabled_drawable" android:state_enabled="true" />
<item android:drawable="#drawable/your_disabled_drawable" android:state_enabled="false" />
<!-- default state-->
<item android:drawable="#drawable/your_enabled_drawable" />
</selector>
Specify the color in selector for android:state_enabled="false" as drawable
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false">
<shape>
<solid android:color="#32ff09" />
</shape>
</item>
</selector>
And apply this drawable resource to background of button
<Button
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/drawble_name"
android:enabled="false"
android:text="Selector Applied Button" />
Try this -
drawable/bg_button.xml :-
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/bg_button_focused" android:state_selected="true"/>
<item android:drawable="#drawable/bg_button_pressed" android:state_pressed="true"/>
<item android:drawable="#drawable/bg_button_disabled" android:state_enabled="false" />
<item android:drawable="#drawable/bg_button_normal"/>
</selector>
After this just set background on your button like this -
<Button
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/bg_button"
android:text="Button"/>
UPDATE: For Android MaterialButton
For Android MaterialButton there are two solutions, one for SDK >= v21 and another for SDK < v21.
Here I am also giving how to change the text color of the button depending whether it is enabled or disabled.
First create two color selector .xml file in your color folder. One for button color and another for button text color. For example button_state_colors.xml for button color and button_text_state_colors.xml for text color.
Here are those two color files:
button_state_colors.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true" android:color="#303F9F" />
<item android:state_enabled="false" android:color="#BBBBBB" />
</selector>
button_text_state_colors.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true" android:color="#FFFFFF" />
<item android:state_enabled="false" android:color="#555555" />
</selector>
Now for all versions of Android SDK you can change the color of button and it's text using style like:
in style.xml:
<style name="Widget.AppTheme.MaterialButton" parent="Widget.MaterialComponents.Button">
<item name="backgroundTint">#color/button_state_colors</item>
<item name="android:textColor">#color/button_text_state_colors</item>
</style>
in layout.xml:
<com.google.android.material.button.MaterialButton
android:id="#+id/button"
style="#style/Widget.AppTheme.MaterialButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
Only for SDK >= 21 you can direct change button color without using style like:
<com.google.android.material.button.MaterialButton
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:backgroundTint="#color/button_state_colors"/>
Another way to achieve this is to create a color selector.
Create a file
res/color/your_color.xml
which looks like
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/colorDisabledBackground" android:state_enabled="false" />
<item android:color="#color/colorEnabledBackground" />
</selector>
Then you may use it as a regular color
in a style:
<style name="YourStyle">
<item name="android:background">#color/your_color</item>
<item name="android:textColor">#android:color/black</item>
</style>
As well is in layouts, shapes or in code as etc.
Here is my code which works properly with button enable and disable state.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true" android:drawable="#drawable/ic_button_gradient"/>
<item android:state_enabled="false" android:drawable="#color/gray"/>
</selector>
I want to change background of a button when it is clicked. I tried to use a selector. But It didn't work. Here is the selector (add_grp_slctr.xml):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:drawable="#drawable/add_grp_d"/>
<item android:state_pressed="true" android:drawable="#drawable/add_grp_d" />
<item android:drawable="#drawable/add_grp" />
</selector>
And the button :
<Button
android:id="#+id/addGrpBtn"
android:layout_width="55dp"
android:layout_height="45dp"
android:layout_gravity="center"
android:background="#drawable/add_grp_slctr"
android:onClick="addGrpDialogOpen" />
add_grp_d and add_grp are images(png).
I tried a similar code which will be white by default, black when pressed on an onclick of a button:
//***This is the btn_selector which is to be declared in drawable folder***
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#android:color/black" /> <!-- pressed -->
<item android:drawable="#android:color/white" /> <!-- default -->
</selector>
and called this on the button.xml -->
android:background="#drawable/btn_selector"
Hope this would help..:)
go through the http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList once. Also state_focussed for button only works when you are focussing the button using a hardware-keyboard.
As for your case
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="false" android:state_selected="false" android:drawable="#drawable/button_default"/>
<item android:state_pressed="true" android:state_selected="false" android:drawable="#drawable/button_default" />
<item android:state_pressed="false" android:state_selected="true" android:drawable="#drawable/button_selected"/>
<item android:state_pressed="true" android:state_selected="true" android:drawable="#drawable/button_selected" />
<item android:drawable="#drawable/button_selected" />
</selector>
Use your selector
change your code like this
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:drawable="#drawable/add_grp_d"/>
<item android:state_pressed="true" android:drawable="#drawable/add_grp" />
<item android:drawable="#drawable/add_grp_d" />
</selector>
My Code
<item android:drawable="#drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="#drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="#drawable/shadow_design"/>
</selector>
I think you should change your selector a bit.
Check this answer here.
Instead of passing cuastom XML file, if you just want to change the color of you button then you can try with the following way.
Button lineColorCode = (Button)findViewById(R.id.button1);
Now inside button's click event use following code.
int color = Color.parseColor("#AE6118"); //The color u want
lineColorCode.setColorFilter(color);
I wanto to change the background-image of a textview when I click it. I have red about the selectors and I did like this:
selector.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/img1" /> <!-- pressed -->
<item android:drawable="#drawable/img2" /> <!-- default -->
</selector>
and then in the layout file:
<TextView
android:id="#+id/textUp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:background="#drawable/selector"
android:clickable="true" />
but it doesn't work. I tried to change the bg color and in this case it works. What am I doing wrong?
You should create a new drawable xml like this:
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!--item android:drawable="#drawable/iv_circle_checked" android:state_pressed="true" />
<item android:drawable="#drawable/iv_circle_unchecked" /-->
<item android:drawable="#drawable/iv_circle_checked" android:state_enabled="true" android:state_pressed="true"/>
<item android:drawable="#drawable/iv_circle_checked" android:state_enabled="true" android:state_focused="true"/>
<item android:drawable="#drawable/iv_circle_checked" android:state_enabled="true" android:state_selected="true"/>
<item android:drawable="#drawable/iv_circle_unchecked" android:state_enabled="true" android:state_selected="false"/>
<item android:drawable="#drawable/iv_circle_unchecked" android:state_enabled="true"></item>
</selector>
When you create this, you should add in your background attr this xml.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/addgrnbtnhov"
android:state_pressed="true"
/>
<item android:drawable="#drawable/addgrnbtn" />
</selector>
please use different images.
// try this way
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/img1" android:state_checked="true" android:state_pressed="false"/>
<item android:drawable="#drawable/img2" android:state_checked="false" android:state_pressed="false"/>
<item android:drawable="#drawable/img1" android:state_checked="true" android:state_pressed="true"/>
<item android:drawable="#drawable/img2" android:state_checked="false" android:state_pressed="true"/>
</selector>
<CheckBox
android:id="#+id/chk"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello"
style="#android:style/Widget.TextView"
android:background="#drawable/selector"
android:gravity="center"
android:checked="true"
android:button="#null"/>
What you can do:
android:onClick="change"
In java:-
public void onCLick(View view){
TextView text=(TextView) findViewById(R.id.textUp);
text.setBackgroungResource(R.drawable.image);
}
Try using scaleType="fitXY"
<TextView
android:id="#+id/textUp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:scaleType="fitXY"
android:background="#drawable/selector"
android:clickable="true" />
I am trying to very simply style a Button. I just want it blue with with text when not pressed, and white with blue text when clicked.
I tried to do this with a style and a selector.
In my layout I have this Button:
<Button
android:id="#+id/button1"
style="#style/MyButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/login" />
And in res/values/styles I have this styles.xml:
<style name="MyButton">
<item name="android:background">#drawable/btn_background</item>
<item name="android:textColor">#drawable/btn_textcolor</item>
</style>
And of course, the two selectors, in res/drawable, btn_background.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:color="#color/white" />
<item android:color="#color/SapphireBlue" />
</selector>
and btn_textcolor.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:color="#color/SapphireBlue" />
<item android:color="#color/white" />
</selector>
The error I get now when I either run the app, or open the layout editor is:
<item> tag requires a 'drawable' attribute
I understand the message, but I don't have a drawable, is it is a simple, flat button.
How can I create such a simple button?
Update according to this post, it should work.
Try this way,hope this will help you to solve your problem.
btn_background.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/white" android:state_pressed="true"></item>
<item android:drawable="#drawable/white" android:state_focused="true"></item>
<item android:drawable="#drawable/SapphireBlue" android:state_enabled="true" android:state_focused="false" android:state_pressed="false"></item>
<item android:drawable="#drawable/white" android:state_enabled="false"></item>
</selector>
btn_textcolor.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/SapphireBlue" android:state_pressed="true"></item>
<item android:color="#drawable/SapphireBlue" android:state_focused="true"></item>
<item android:color="#drawable/white" android:state_enabled="true" android:state_focused="false" android:state_pressed="false"></item>
<item android:color="#drawable/SapphireBlue" android:state_enabled="false"></item>
</selector>
Background attribute expects a drawable and the drawable selector must be in one of the /drawable folders.
TextColor attribute expects a color and the color selector must be in one of the /color folders.
/res/color/my_textcolor_selctor.xml
/res/drawable/my_background_selector.xml
Also, the drawable selector must use 'android:drawable' for selector items (a color resource maybe used for the attribute value since a color is a drawable),
whereas the color selector must use 'android:color' for the selector items.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false"
android:drawable="#color/disabledbackgroundColor" />
<!-- default -->
<item android:drawable="#color/myBackgroundColor" />
</selector>
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false"
android:color="#color/disabledColor" />
<!-- default -->
<item android:color="#color/defaultColor" />
</selector>
android:background seems to accept drawable selectors but not color selectors... so just leave a color as your android:background, and use a normal color selector with android:backgroundTint, which expects colors anyway:
at styles.xml:
<style name="MyButton">
<item name="android:background">#color/some_fixed_color</item>
<item name="android:backgroundTint">#color/background_color_selector</item>
<item name="android:textColor">#drawable/btn_textcolor</item>
</style>
(res/color/background_color_selector.xml is a normal color selector.)
