i am designing for the button using the icon samples, and wish that when icon is not pressed, it is black, and become white when it is pressed. Coding as follows:
in layout xml:
<Button
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
android:background="#drawable/icon_new_btn"
android:scaleType="fitXY"
android:id="#+id/newBtn" />
in icon_new_btn.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:drawableTop="#drawable/icon_new_white"
android:background="#android:color/transparent"/>>
</shape>
</item>
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:drawableTop="#drawable/icon_new"
android:background="#android:color/transparent"/>
</shape>
</item>
</selector>
Question1 (seem to be solved using the below modification):
The whole button becomes invisible on the screen (it can still be pressed at that screen location!). How could I modify the above coding for meeting the purposes defined? Thanks!!
Modification but new Question (Question2):
The following modified layout and selector seem to be solving the above Question 1. Yet the resolution become much poorer and icon distorted and looks bigger. See the below screenshot for the first and second icon using the below modified codes (icon 3 to 6 are simply using android:drawableTop="#drawable/icon_save" without any pressing effect and showing higher resolution):
modified layout
<Button
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
android:background="#drawable/icon_new_btn"
android:scaleType="fitXY"
android:id="#+id/newBtn" />
modified selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/icon_new_white"
android:state_pressed="true" />
<item android:drawable="#drawable/icon_new" />
</selector>
The reason your graphic is being distored is because it being set as the background. To resolve this, you can instead use an ImageButton:
<ImageButton
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
android:src="#drawable/icon_new_btn"
android:background="#null"
android:id="#+id/newBtn" />
Also, you had specified android:scaleType="fitXY". You might instead want android:scaleType="centerInside".
Hi I'm posting the answer for you .
create 4 xml files in res/layout.
state.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Button Focused-->
<item android:state_focused="true"
android:state_pressed="false"

/>
<!-- Button Focused Pressed-->
<item android:state_focused="true"
android:state_pressed="true"
android:drawable="#layout/state1"
/>
<!-- Button Pressed-->
<item android:state_focused="false"
android:state_pressed="true"
android:drawable="#layout/state1"
/>
<!-- Button Default Image-->
<item android:drawable="#layout/state2"/>
</selector>
state1.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" shape="rectangle">
<!--this is to give gradient effect -->
<gradient android:angle="270"
android:startColor="#6b6b6b"
android:endColor="#0e0e0e"
/>
<!-- this is make corners of button rounded -->
<corners android:topLeftRadius="5dip"
android:bottomRightRadius="5dip"
android:topRightRadius="5dip"
android:bottomLeftRadius="5dip"/>
</shape>
state2.xml

/>
<!-- this is make corners of button rounded -->
<corners android:topLeftRadius="5dip"
android:bottomRightRadius="5dip"
android:topRightRadius="5dip"
android:bottomLeftRadius="5dip"/>
</shape>
In activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="183dp"
android:text="Click Here To Change Color"
android:background="#layout/state"/>
</RelativeLayout>
Java file
MainActivity.java
package com.example.getimage;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
thats all enjoy coding:)

I design my button in round shape by using this below code and then i want to show some text on button so i used Frame Layout and then i put some text on my button.
Now the Challange is that my button is still.it doesnot show any effect on click
where the drawable and src both are used one for roundshape button and other for image on button (respectivitly).
Now my button doesnot make any effect on design on click how i make that effect.
<FrameLayout>
<ImageButton
android:id="#+id/btn_profile_view"
android:layout_width="70dp"
android:layout_height="67dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="20dp"
android:layout_weight="1"
android:onClick="compareButtonClick"
android:background="#drawable/roundedbutton"
android:src="#drawable/ic_action_person" />
<TextView
android:layout_width="45dp"
android:layout_height="20dp"
android:layout_gravity="bottom"
android:layout_marginLeft="38dp"
android:clickable="false"
android:text="#string/profile"
android:textColor="#color/btn_txt" >
</TextView>
</FrameLayout>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#D3D3D3" />
<corners
android:bottomLeftRadius="8dip"
android:bottomRightRadius="8dip"
android:topLeftRadius="8dip"
android:topRightRadius="8dip" />
Here you will get your click call back, you dont need to set click listener anywhere
public void compareButtonClick(View v){
Toast.makeText(this, "Image Button Click", Toast.LENGTH_SHORT).show();
}
This might help, but you have to modify it to suit your need.
1) Create roundedbutton.xml in drawable folder
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#D3D3D3" />
<corners
android:bottomLeftRadius="8dip"
android:bottomRightRadius="8dip"
android:topLeftRadius="8dip"
android:topRightRadius="8dip" />
</shape>
2) Create button_normal.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/roundedbutton" android:state_focused="true" android:state_pressed="true"/>
<item android:drawable="#drawable/ic_launcher" android:state_focused="false" android:state_pressed="true"/>
<item android:drawable="#drawable/ic_launcher" android:state_focused="true"/>
<item android:drawable="#drawable/roundedbutton" android:state_focused="false" android:state_pressed="false"/>
<!-- 2 and 3 pressed and selected -->
</selector>
3) Add button_normal.xml as background to your button
android:background="#drawable/button_normal"
Create a selector with different drawables to handle the different states; enabled, disabled, clicked,focused, etc
I have few buttons.
I'd like to change color of a button when it is pressed.
And to change color of other buttons to normal state.
The problem is that after simple changing the background of a button,
it's shape is also changed. After changing the color the default android
button with shadows
is just replaced with painted rectangle with more button height.
Yes. It is possible to define button in normal and pressed positions as drawable XMLs.
But I'd like to use default android buttons instead of fancy mine.
My code is below:
buttonAny.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
buttonAny.setBackgroundColor(COLOR_BUTTON_SELECTED);
buttonMale.setBackgroundColor(COLOR_BUTTON_GRAY);
buttonFemale.setBackgroundColor(COLOR_BUTTON_GRAY);
}
});
buttonMale.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
buttonAny.setBackgroundColor(COLOR_BUTTON_GRAY);
buttonMale.setBackgroundColor(COLOR_BUTTON_SELECTED);
buttonFemale.setBackgroundColor(COLOR_BUTTON_GRAY);
}
});
XML:
<Button
android:id="#+id/buttonGenderAny"
android:layout_marginLeft="#dimen/dim1"
android:layout_marginRight="#dimen/dim1"
android:gravity="center"
android:layout_centerHorizontal="true"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:text='Any'
android:textColor="#color/text1"
android:textAppearance="?android:attr/textAppearanceSmall" />
<Button
android:id="#+id/buttonGenderMale"
android:layout_marginLeft="#dimen/dim1"
android:layout_marginRight="#dimen/dim1"
android:gravity="center"
android:layout_centerHorizontal="true"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:text='Male'
android:textColor="#color/text1"
android:textAppearance="?android:attr/textAppearanceSmall" />
My app after start looks as follows
pic1
(Sorry I have not permission to post images)
After I press a button it is as follows:
pic2
Very strange, that the size of the buttons was changed.
There are many similar questions in google.
But it seems they do not suit me.
For example this link.
But there is not written how to define normal or pressed button in drawable.
So. What is the best way to change (switch) colors of a few buttons.
Thanks!
create a new xml file under your drawable resourses with the properties you want to apply to your button... for example...
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#c53e2b" />
<gradient android:angle="-90" android:startColor="#a11005" android:endColor="#d62608" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#c53e2b" />
<solid android:color="#e0341e"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#c53e2b" />
<gradient android:angle="-90" android:startColor="#ff6c52" android:endColor="#e0341e" />
</shape>
</item>
</selector>
then in the on click listener aplyy it like this...
buttonMale.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
buttonAny.setBackgroundResource(R.drawable.YOUR_XML_NAME);
buttonMale.setBackgroundResource(R.drawable.YOUR_XML_NAME);
buttonFemale.setBackgroundResource(R.drawable.YOUR_XML_NAME);
}
});
Yeah, don't try to change the button color in your onClick event.
What you are looking for is a StateListDrawable. As an example, check out how the Android platform defines the drawable btn_default_holo_light. You will want to follow exactly this pattern, providing your own drawables (e.g. PNG images) for the different states.
Once you've got these drawables created, you simply reference it in your layout file like this
<Button
...
android:background="#drawable/my_fancy_button_background" />
You can do it like this,create a xml file int project's res/drawable,eg:"buttonGenderAny_bg.xml":
<?xml version="1.0" encoding="utf-8"?>
<item android:drawable="COLOR_BUTTON_SELECTED" android:state_pressed="true"/>
<item android:drawable="COLOR_BUTTON_SELECTED" android:state_focused="true"/>
<item android:drawable="COLOR_BUTTON_SELECTED" android:state_selected="true"/>
<item android:drawable="COLOR_BUTTON_GRAY"/>
then set button's background in layout xml file,eg:
<Button
android:id="#+id/buttonGenderMale"
android:layout_marginLeft="#dimen/dim1"
android:layout_marginRight="#dimen/dim1"
android:gravity="center"
android:layout_centerHorizontal="true"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:text='Male'
android:textColor="#color/text1"
android:textAppearance="?android:attr/textAppearanceSmall"
android:background="#drawable/buttonGenderAny_bg"/>
Actually I also did some thing like this a few months back with buttons, but I don't recommend it. I think for your situation it is much simpler to use radio buttons.
This is what it looked like!
The advantage of using the RadioGroup method is that you do not have to manage the color state of your "buttons"
To setup the following 3 or 4 files are needed (This is my EXACT usage, but I have also provided a few hints on how to get it like how you want it):
Layout:
<RadioGroup
android:id="#+id/sortOptionsBar"
style="?android:attr/buttonBarStyle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:checkedButton="#+id/rbSortOption1"
android:orientation="horizontal" >
<RadioButton
android:id="#+id/rbSortOption1"
style="#style/menu_buttons"
android:text="#string/sort_option1" />
<RadioButton
android:id="#+id/rbSortOption2"
style="#style/menu_buttons"
android:text="#string/sort_option2" />
<RadioButton
android:id="#+id/rbSortOption3"
style="#style/menu_buttons"
android:text="#string/sort_option3" />
</RadioGroup>
HINT: Above I wanted mine to look like a bar, for yours switch the android:orientation="horizontal" to vertical.
values\style.xml (To bring together all the styling for the radio buttons)
<style name="menu_buttons" parent="#android:style/Widget.Holo.Button.Borderless">
<item name="android:textColor">#color/menu_button_text</item>
<item name="android:background">#color/menu_button_background</item>
<item name="android:button">#android:color/transparent</item>
<item name="android:layout_weight">1.0</item>
</style>
What is important to note is the android:button above, this hides the checkbox of the radiobutton
You can also remove the android:layout_weight I used this in my bar so that all the radio buttons would get equal width.
The parent="#android:style/Widget.Holo.Button.Borderless" will allow you to keep the buttons the same size.
color\menu_button_background.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:state_pressed="true" android:drawable="#drawable/menu_button_unselected" />
<item android:state_pressed="true" android:drawable="#drawable/menu_button_selected" />
<item android:state_checked="true" android:drawable="#drawable/menu_button_selected" />
<item android:drawable="#drawable/menu_button_unselected" />
</selector>
The same can be done for the #color/menu_button_text. (For example you could invert the color of the text when it is selected)
Then to know which one is selected in the onCheckedChanged event I did this.
int id = sortBar.getCheckedRadioButtonId();
switch (id) {
case R.id.rbSortOption1:
break;
case R.id.rbSortOption2:
break;
case R.id.rbSortOption3:
break;
}
Instead of trying to change colors in the code just use a selector for all the buttons as the background property of each button.
Selector:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true"><color android:color="#color/button_background_pressed" />
</item>
<item android:state_pressed="true"><color android:color="#color/button_background_pressed" />
</item>
<item><color android:color="#color/button_background" />
</item>
</selector>
EDIT:
You can create a selector with the above XML in your drawable folder and just use it as a background with "#drawable/selector_button"
EDIT 2:
Instead of using it like this:
<Button
android:id="#+id/buttonGenderMale"
android:layout_marginLeft="#dimen/dim1"
android:layout_marginRight="#dimen/dim1"
android:gravity="center"
android:layout_centerHorizontal="true"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:text='Male'
android:textColor="#color/text1"
android:textAppearance="?android:attr/textAppearanceSmall" />
Use it like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:orientation="vertical" >
<View
android:layout_width="match_parent"
android:layout_height="1dip" />
<Button
android:id="#+id/buttonGenderMale"
android:layout_marginLeft="#dimen/dim1"
android:layout_marginRight="#dimen/dim1"
android:gravity="center"
android:layout_centerHorizontal="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text='Male'
android:textColor="#color/text1"
android:textAppearance="?android:attr/textAppearanceSmall" />
</LinearLayout>
Adjust the View for the distance you want between buttons!
All you have to do is create an xml file in the drawable folder which will set the back ground colour of your buttons according to the states i.e pressed or not.
For example create a file and call it button_background.xml and place it in drawable folder.The in the file put the following
<item android:state_pressed="true" >
<shape android:shape="rectangle">
<solid android:color="#449def" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#2f6699" />
</item>
Then in your button background attribute
<Button
android:background="#drawable/button_background"/>
You can edit the colors in the button_background file to your taste.
I have an image button and I want to change the color of a button when pressed. First I show it with a transparent as a default state color as below. But it doesn't show highlighted when pressed. So I decided to use other color to highlight when pressed using state drawable. But how to keep background color through styles wise. Means by default it should be transparent and when pressed it has to show other color.
present code:
<ImageButton
android:id="#+id/imgbutton"
android:layout_width="20dp"
android:layout_height="match_parent"
android:layout_gravity="center"
android:src="#drawable/ic_launcher"
android:background="#android:color/transparent"
/>
Need to be coded:
<ImageButton
android:id="#+id/imgbutton"
android:layout_width="20dp"
android:layout_height="match_parent"
android:layout_gravity="center"
android:src="#drawable/ic_launcher"
android:background="#drawable/btnselector"
/>
So what should be the btnselector.xml here?
put it inside res/color
<?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/green_text_color"/> <!-- pressed -->
<item android:state_focused="true" android:color="#color/green_text_color"/> <!-- focused -->
<item android:color="#android:color/white"/> <!-- default -->
</selector>
create a new shape, inside res/drawable
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/yourxmlfile" />
</shape>
and put it as background
or a res/drawable selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/green_botton_pressed"
android:state_pressed="true" />
<item android:drawable="#drawable/green_botton_highlited"
android:state_focused="true" />
<item android:drawable="#drawable/green_botton" />
</selector>
I customized the Toggle button by using a drawable defined by using a selector. I use this drawable as background for the Toggle button.
<ToggleButton
android:id="#+id/mailbox:toggle_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_weight="1"
android:background="#drawable/toggle_background"
android:gravity="center_horizontal|center_vertical" />
The toggle_background is defined here:
<?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" />
<item
android:drawable="#drawable/img2"
android:state_checked="false" />
</selector>
The problem is that the image is always stretched. Is there a way to define an image for the two states that is not stretched?
What I need is a background that will be stretched and in the center of the button an icon that must not be stretched.
Is it possible?
This is my final solution.
In the layout:
<ToggleButton
android:id="#+id/mailbox:toggle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/toggle_drawable_layers"/>
in the toggle_drawable_layers.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/toggle_drawable_bkg"></item>
<item android:left="10dp" android:drawable="#drawable/toggle_drawable_left"
android:gravity="center_vertical|center_horizontal" />
</layer-list>
in the toggle_drawable_left.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true">
<bitmap android:src="#drawable/bitmap_checked"
android:gravity="center_vertical|center_horizontal" />
</item>
<item android:state_checked="false">
<bitmap android:src="#drawable/bitmap_unchecked"
android:gravity="center_vertical|center_horizontal" />
</item>
</selector>
I did the same task this way, the button:
<ToggleButton android:id="#+id/mlAbout"
android:textOn="#string/about"
android:textOff="#string/about"
android:background="#drawable/ml_about" />
#drawable/ml_about:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/list_bg_top"></item>
<item android:left="10dp">
<bitmap android:src="#drawable/waiting_status_btn"
android:gravity="center_vertical|left" />
</item>
</layer-list>
#drawable/list_bg_top background image that will be stretched and #drawable/waiting_status_btn is the icon the will not be stretched with the widget
Just use bitmaps instead of drawables in your selector like so (no need to use layers):
<?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" />
<item
android:drawable="#drawable/img2"
android:state_checked="false" />
</selector>
Also, don't forget to declare
android:textOff=""
android:textOn=""
in your ToggleButton declaration
There is another way to overcome the issue of stretching:
Just convert the image into a Nine-Patch image, where the stretchable areas are just on all sides of the image.
Then Android will stretch the image only in invisible areas, and keep the visible image unchanged.
I need to do round cornered button with background color change in android.
How could i do that?
Example link/code is much appreciated.
You want to use Android's Shape Drawables.
http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape
drawable/cool_button_background.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="#dimen/corner_radius" />
<gradient
android:angle="270"
android:startColor="#color/almost_white"
android:endColor="#color/somewhat_gray"
android:type="linear" />
</shape>
Then you'd have to create a "selector" drawable from those shape drawables. This allows you to make the button appear different depending on the state. IE: Pressed, focused, etc.
http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList
drawable/cool_button.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/cool_inner_press_bottom" />
<item android:state_focused="true" android:state_enabled="true"
android:state_window_focused="true"
android:drawable="#drawable/cool_inner_focus_bottom" />
<item
android:drawable="#drawable/cool_button_background" />
</selector>
Bonus: You might want to create a style for the button so you can have them be consistent throughout the program. You can cut this step out and just set the button's android:background="#drawable/cool_button".
values/styles.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyCoolButton">
<item name="android:background">#drawable/cool_button_background</item>
</style>
</resources>
Finally, the button!
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#drawable/appwidget_bg">
<Button
android:id="#+id/btnAction"
android:layout_width="wrap_content"
android:layout_weight="wrap_content"
style="#style/CoolButton"
/>
</LinearLayout>
Import PorterDuff and use setColorFilter() as follows
import android.graphics.PorterDuff.Mode;
Button btn = (Button) findViewById(R.id.myButton);
btn.getBackground().setColorFilter(Color.GRAY, Mode.MULTIPLY);
