I have a problem of using selector that it does not work as what I expect. I wanna click on it then it gives me reaction and I select it(By long click but I probably do it through programmatic way) then it gives me another reaction. However, it reacts nothing in result....
reaction part:
<TableRow
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="10"
android:padding="5dp"
android:background="#drawable/border_bottom"
>
<LinearLayout
android:layout_weight="9"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/selector_row">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/grey"
android:text="#string/tel"/>
<TextView
android:id="#+id/telText"
android:layout_width="wrap_content"
android:textSize="18sp"
android:layout_height="wrap_content"
android:text="#string/blank"/>
</LinearLayout>
<ImageButton
android:layout_weight="1"
android:id="#+id/tel_call"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:src="#drawable/ic_action_call"
android:background="#drawable/border_left"/>
</TableRow>
selector_row.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="#color/semitransparent_grey"></item>
<item
android:state_selected="true"
android:drawable="#color/semitransparent_blue"></item>
<item
android:drawable="#color/transparent"></item>
</selector>
Thank you to all brothers trying hard to answer me. I have got the answer....just simply by setting android:clickable="true" at LinearLayout. Ha, it's silly.....
I remember dude who provide relating information but I ignored... sorry to him.
Create an XML file and place it in the drawable folder. Open it and write the following code:
<selector
xmlns:android="http://schemas.android.com/apk/res/android"
>
<item
android:drawable="YOUR IMAGE OR COLOR"
android:state_pressed="true"/>
<item
android:drawable="YOUR IMAGE OR COLOR"
android:state_selected="true"/>
<item
android:drawable="YOUR IMAGE OR COLOR"
android:state_focused="true"/>
</selector>
Then in your main XML file, place android:background="#drawable/selector.xml"
What are you expecting? A reaction only when it's clicked?
Try removing removing:
android:state_selected="true"
Edit:
This should be your selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/my_drawable" android:state_selected="true"></item>
<item android:drawable="#drawable/my_drawable" android:state_pressed="true"></item>
<item android:drawable="#drawable/my_drawable"></item>
</selector>
What is the behaviour that you are experiencing?
Edit:
<LinearLayout
android:layout_weight="9"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/selector_row"
android:duplicateParentState=true>
I don't know if it actually solves the problem

I want to use 2 pictures for one button to make a effect when user click it.
I think I did properly but, the effect does not work.
Specifically, the button background set to camera_button_after.jpg which is meant for pressed state and does not change when it is clicked.
Could you tell me what's wrong? I'll be very appreciated.
Here is the main_frame.xml which contains buttons.
main_btn1.xml, main_btn2.xml, main_btn3.xml are selectors.
Those three selectors have same structure and also same problem..
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button001"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#drawable/main_btn1"
android:text=" Mood"
android:textSize="30dp"/>
<Button
android:id="#+id/button002"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#drawable/main_btn2"
android:text=" Mood Lists"
android:textSize="30dp"/>
<Button
android:id="#+id/button003"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#drawable/main_btn3"
android:text=" Help"
android:textSize="30dp" />
</LinearLayout>
Here is the main_btn1.xml
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="false"
android:drawable="#drawable/camera_button_before" />
<item
android:state_pressed="true"
android:drawable="#drawable/camera_button_after"/>
</selector>
One more question is..I think the eclipse doesn't fully recognize the pictures and xml files. I cleaned the project few times and reboot the eclipse but it they still have question mark like below
I was facing the similar problem. I tried the below code. I did get this solution from stack overflow itself, but do not have its link for reference. So writing the code snippet for xml in drawable folder. Do remember to provide the right image names :)
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_enabled="false"
android:drawable="#drawable/image1" />
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="#drawable/image2" />
<item
android:state_focused="true"
android:state_enabled="true"
android:drawable="#drawable/image3" />
<item
android:state_enabled="true"
android:drawable="#drawable/image4" />
</selector>
Let me know how it works for you.
Replace your xml with this.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="#drawable/camera_button_before" />
<item
android:state_pressed="true"
android:drawable="#drawable/camera_button_after"/>
In my android application, I am trying to make a simple toggle button switching between two images, actually a star to mark as favorites. States of the button are being changed but images are not switching for ON and OFF states. Image of the OFF state is being displayed by default continuously.
I have tried the following tutorials:
http://www.coderzheaven.com/2012/05/20/create-custom-toggle-button-android/
http://www.technotalkative.com/android-custom-toggle-button-example/
** togbtn_fav_custom.xml **
<item android:drawable="#drawable/ic_action_important" android:state_checked="true" android:state_pressed="true"/>
<item android:drawable="#drawable/ic_action_important" android:state_checked="true" android:state_focused="false"/>
<item android:drawable="#drawable/ic_action_not_important" android:state_checked="false" android:state_pressed="true"/>
<item android:drawable="#drawable/ic_action_not_important" android:state_checked="false" android:state_focused="false"/>
layout.xml
<LinearLayout 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"
android:orientation="vertical"
>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<LinearLayout
android:id="#+id/ll_back_single_dua_footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical" >
<Button
android:id="#+id/btn_play_pause_dua"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="#drawable/play_btn_custom" />
<TextView
android:id="#+id/tv_back_single_dua_footer_counter"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:singleLine="true"
android:text="#string/sample_counter"
android:textSize="23sp" />
<ToggleButton
android:id="#+id/tog_btn_favorite_dua"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/togbtn_fav_custom"
android:textOff=""
android:textOn=""
/>
</LinearLayout>
</LinearLayout>
Can anybody please guide me what am I missing?
Try to simplify your selector.xml like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/ic_action_not_important" android:state_checked="false"/>
<item android:drawable="#drawable/ic_action_important" android:state_checked="true"/>
</selector>
And as Achilles said, check line
android:background="#drawable/togbtn_fav_custom"
May be you need to set selector.xml as background?
This is what is happening:
This is the source image:
This is part of the xml layout:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_headers"
android:orientation="horizontal" >
<AutoCompleteTextView
android:id="#+id/etNewItem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:completionThreshold="2"
android:dropDownHeight="wrap_content"
android:dropDownWidth="wrap_content"
android:hint="#string/et_newitemhint"
android:inputType="text|textCapSentences"
android:layout_centerVertical="true"
style="#style/DialogEditText"
android:layout_marginRight="10dp"
android:singleLine="true" />
<Button
android:id="#+id/btnAddNew"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:background="#drawable/btn_add"
android:layout_centerVertical="true" />
</RelativeLayout>
This is the Selector xml for the button:
<?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/btn_add_pressed"/>
<item android:state_pressed="true"
android:drawable="#drawable/btn_add_pressed"/>
<item android:drawable="#drawable/btn_add_normal"/>
</selector>
Why is this button horizontally resizing in 4.x.x? The source graphic did use to be a 9-patch, but it did exactly the same thing, so I changed it to a normal png, with no result.
The odd thing is is that this is the only graphic which exhibits this behaviour. I have it in an actionbar somewhere: same thing; I have it in a dialog too: same thing.
My 2.2.2 and 2.3.6 test devices show the button as it should be, but any of my test devices of 4.x.x show the elongated button.
First, make these:
res/drawable/button_add_normal.xml
<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/btn_add_normal"
android:tileMode="disabled"
android:gravity="top" >
</bitmap>
res/drawable/button_add_pressed.xml
<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/btn_add_pressed"
android:tileMode="disabled"
android:gravity="top" >
</bitmap>
Then use this as selector:
<?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/button_add_pressed"/>
<item android:state_pressed="true"
android:drawable="#drawable/button_add_pressed"/>
<item android:drawable="#drawable/button_add_normal"/>
</selector>
I didn't manage to reproduce this on my devices. However, I still have a solution: you can use exact sizes like this:
android:layout_width="50dp"
android:layout_height="50dp"
This way the image should look the same on every device.
i want to make image button, so when it pressed i will replase the not-pressed image to pressed image of the button, and then go to other activity. i have two different images in drawable.
i have two xml files:
first one- load the main activity: background and image button
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/black"
android:orientation="vertical" >
<ImageButton
android:id="#+id/b1_l"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/s1"
android:scaleType="centerCrop"
android:background="#color/trans"
android:src="#drawable/b1_l" />
</RelativeLayout>
second one:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="false"
android:drawable="#drawable/image_not_pressed" />
<item android:state_pressed="true"
android:drawable="#drawable/image_pressed"" />
</selector>
what is the code that i need to write in addition to my xml?
or can i pass the xml and write it only as code...?
thanks!
you need to usually have drawable for pressed and default(unpressed) state. You can have the xml file like this(below) for that. You need to put this xml file in the drawable folder and then use as src for ImageButton or background source in case of Button.
Lets name it is mybutton.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="true"
android:drawable="#drawable/your image name" />
<item android:state_focused="false" android:state_pressed="true"
android:drawable="#drawable/your image name" />
<item android:drawable="#drawable/your image name" />
</selector>
You layout file for main activity:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/black"
android:orientation="vertical" >
<ImageButton
android:id="#+id/b1_l"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/s1"
android:scaleType="centerCrop"
android:background="#color/trans"
android:src="#drawable/mybutton" />
</RelativeLayout>
You migth want do check out android developer guide on this

I am creating a custom ListView as below
Main Layout
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center">
<ListView android:id="#+id/listview"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_margin="3dip"
android:fadingEdge="none"
android:soundEffectsEnabled="true"
android:clickable="true"
android:scrollbars="none"
android:divider="#ffcccccc"
android:dividerHeight="1dip"
android:layout_weight="1"/>
</LinearLayout>
Custom ListView
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#drawable/sellistitem">
<TextView
android:id="#+id/ListItem"
android:layout_width="wrap_content"
android:layout_height="30dip"
android:layout_margin="1dip"
android:textColor="#color/BLACK"
android:gravity="center_vertical"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:padding="5dip"/>
</RelativeLayout>
and Selector as below
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#drawable/BLUE" />
<item android:drawable="#drawable/WHITE" />
</selector>
The Drawable
<resources>
<drawable name="WHITE">#ffffff</drawable>
<drawable name="BLUE">#ff0033cc</drawable>
</resources>
Having done this the selection part works fine. However when I click on any item ,the selected item blinks twice before actually changing to blue. It doesn't change to blue directly as it should. How can I remove this blinking effect?
Regards,
try this android:cacheColorHint="#00000000" to listview
Selectors are tricky, in general. Try this for your selector instead:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:state_enabled="true"
android:drawable="#drawable/selected_background" />
<item android:state_focused="false"
android:state_pressed="false"
android:state_selected="false"
android:state_checked="false"
android:state_enabled="true"
android:state_checkable="false"
android:drawable="#drawable/normal_background"/>
</selector>
Note that the android:drawable attribute does not have to be a drawable. If it's a simple color you can reference it with the #color/background_color format.
EDIT:
Ok, those white and blue "drawables" aren't drawables, they're just colors, you're better off defining them in the colors.xml. It could be that that is actually the reason for the flickering.
<resources>
<color name="blue">#ff0033cc</color>
<color name="white">#ffffff</color>
</resources>
