i have a ListView in my Navigation Drawer and want it looks like the Playstore App or Youtube App.
Means onClick changing FontColor for Example to red and when i just hold it the background should turn grey.
Do i have to use 2 onitemclicklistener?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp">
<ImageView
android:id="#+id/icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:contentDescription="#string/DrawerListIcon"
android:src="#drawable/ic_home"
android:layout_centerVertical="true" />
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toRightOf="#id/icon"
android:textSize="14sp"
android:textStyle="bold"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:textColor="#color/DrawerListFontColor"
android:gravity="center_vertical"
android:paddingRight="40dp"
android:paddingLeft="0dp"/>
</RelativeLayout>
Tried with Item and Selector. First thing Font Color don't change when i pressed the Button. Second the background of the Relative Layout turns blue insead of Grey.
drawer_list_font.xml
<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_focused="true"
android:color="#color/DrawerListFontColorPressed"
/>
<item android:color="#color/DrawerListFontColor"/></selector>
drawer_list_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:color="#color/DrawerListBackgroundFocused"
/>
<item
android:color="#color/DrawerBackground"
/></selector>
I had to use android:drawable instead of background on the relative Layout. On the Textview Android Stuio accepted android:color.
This is changed by changing view from ur java file at every click event u can change the view. U have to make multiple view ie xml files for that. Which are dynamically changed or u can also send parameters to a function and create an xml at runtime but that will be too deep for u
No need for listeners at all.
A better approach here is to create drawable XML's with definitions for every state ("pressed", "focused", etc).
Check out Color State List resources
For example:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:state_pressed="false"android:color="#80000" />
<item android:state_focused="true" android:state_pressed="true" android:color="#ff0000" />
<item android:state_focused="false" android:state_pressed="true" android:color="#ff0000" />
<item android:color="#color/DrawerListFontColor" />
</selector>

I need to highlight widgets as per the following design, In below design all three widgets are highlighted in red when the cursor reaches the position
I have written the following code to achieve above:
left_strip_color_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="#color/focus_color"/>
<item android:state_focused="true" android:drawable="#color/focus_color" />
<item android:drawable="#color/menu_list_bg" />
</selector>
leftmenu_text_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/focus_color"/> <!-- pressed -->
<item android:state_focused="true" android:color="#color/focus_color"/> <!-- focused -->
<item android:color="#color/white"/> <!-- default -->
</selector>
leftmenu_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.leanback.widget.NonOverlappingLinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/background"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="horizontal"
android:gravity="center_vertical">
<View
android:layout_width="4dp"
android:layout_height="17dp"
android:layout_marginEnd="22dp"
android:focusable="true"
android:focusableInTouchMode="true"
android:background="#drawable/left_strip_color_selector"></View>
<ImageView
android:id="#+id/left_menu_icon"
android:layout_width="25dp"
android:layout_height="25dp"
android:layout_marginEnd="15dp"/>
<com.zeenews.tv.base.BaseTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:focusableInTouchMode="true"
android:id="#+id/left_menu_text"
android:lines="1"
android:textSize="14sp"
android:textColor="#color/leftmenu_text_selector"
android:textAllCaps="true"/>
</androidx.leanback.widget.NonOverlappingLinearLayout>
Note: For now, I have implemented the above code for red strip and menu text only
With the above code, I am getting below effects when I move the cursor from one menu option to another (only strip is getting colored and text is not getting colored.)
My Question: Am I doing something wrong? Can two widgets receive focus at the same time? Can I achieve these effects using any other standard coding practice?
I'm trying to make a custom switch like this:
with these properites:
text on both sides always shown.
different colors for on and off.
and these are two problems I faced since the switch only shows the text on the chosen side , and I can't seem to find a place where I can specify two different colors?
can I achieve this using the regular switch in android studio or must I use some library?
Thank you.
After researching I found a way that gives me exactly what I needed, this is what I got:
in case of anyone looking for a way to do it, this is how:
based on this post answer , which worked great for me.
this is what I did, I created two drawables one for On and another for Off :
switch_on.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:state_checked="true" android:drawable="#color/colorGray"/>
<item android:drawable="#color/colorPrimary" android:state_checked="true" />
<item android:drawable="#color/colorPrimaryDark" android:state_pressed="true" />
<item android:drawable="#color/transparent" />
</selector>
switch_off.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:state_checked="true" android:drawable="#color/colorGray"/>
<item android:drawable="#color/gray_light" android:state_checked="true" />
<item android:drawable="#color/black_overlay" android:state_pressed="true" />
<item android:drawable="#color/transparent" />
</selector>
Next , created a drawable for the outline of the switch.
outline.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="2dp" />
<solid android:color="#80ffffff" />
<stroke
android:width="1dp"
android:color="#color/gray_light" />
</shape>
one thing that I added is a drawable for the text color, because the color of the text changes depending on whether it's checked or not, this is it :
switch_text.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/colorWhite"/>
<item android:state_checked="true" android:color="#color/colorWhite"/>
<item android:color="#color/gray_light"/>
</selector>
and finally, created RadioGroup in my layout this way:
<RadioGroup
android:id="#+id/toggle"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:background="#drawable/outline"
android:checkedButton="#+id/off"
android:orientation="horizontal">
<RadioButton
android:id="#+id/off"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginBottom="1dp"
android:layout_marginStart="1dp"
android:layout_marginTop="1dp"
android:layout_weight="1"
android:background="#drawable/switch_off"
android:button="#null"
android:gravity="center"
android:padding="#dimen/fab_margin"
android:text="#string/off"
android:textColor="#drawable/switch_text" />
<RadioButton
android:id="#+id/on"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginBottom="1dp"
android:layout_marginEnd="1dp"
android:layout_marginTop="1dp"
android:layout_weight="1"
android:background="#drawable/switch_on"
android:button="#null"
android:gravity="center"
android:padding="#dimen/fab_margin"
android:text="#string/on"
android:textColor="#drawable/switch_text" />
</RadioGroup>
Notice the usage of each drawable in the right place:
android:background="#drawable/outline" for the RadioGroup
android:background="#drawable/switch_off" for the first RadioButton
android:background="#drawable/switch_on" for the second RadioButton
android:textColor="#drawable/switch_text" for both Radio Buttons
And that's all.
Use ToggleButton(change height/width as per image ratio) & selector, here's the code
<ToggleButton
android:id="#+id/toggle_"
android:layout_width="60dp"
android:layout_height="30dp"
android:layout_alignParentStart="true"
android:background="#drawable/on_off"
android:textOff=""
android:textOn=""/>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#drawable/ic_on" />
<item android:state_checked="false"
android:drawable="#drawable/ic_off" />
</selector>
To create ON and OFF labels for the switch you can use the attributes android:textOn and android:textOff with the switch declaration.
To ensure, that the text lebals are always displayed, especially for API Level bigger API21, also use this attribute: android:showText="true".
Then your switch should look like this:
<Switch
android:id="#+id/switcher"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="OFF"
android:textOn="ON"
android:showText="true"
/>
In order to change the default color, you have to specify a seperate design for it like that:
1. In file values\styles.xml define a style like that:
<style name="CustomSwitchTheme" parent="Theme.AppCompat.Light">
<item name="android:colorControlActivated">#FF0000</item>
</style>
It is important, that you also reference the correct parent theme.
2. After defining the new switch style, you can link your custom style to the switch with the attribute
android:theme="#style/CustomSwitchTheme"
Finally your Switch should look like that:
<Switch
android:id="#+id/switcher"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="OFF"
android:textOn="ON"
android:showText="true"
android:theme="#style/CustomSwitchTheme"
/>
I am creating a simple button as follows :
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/edSearch"
android:id="#+id/btnSearch"
android:layout_marginTop="30dp"
android:drawableTop="#drawable/ic_action_search"
android:textSize="16sp"
android:text="Search"
android:background="#color/md_green_500"
android:textColor="#fff"
/>
Now, when i try add any image in background like :android:background="#drawable/img123" then button raise effect does not work. is there any way i can achieve raise effect with background image ?
You can create a selector drawable for this. You need to provide 3 different images for this so that the button can toggle those images as per the state.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="false"
android:state_pressed="false"
android:drawable="#drawable/image_normal" />
<item android:state_focused="false"
android:state_pressed="true"
android:drawable="#drawable/image_pressed" />
<item android:state_focused="true"
android:state_pressed="false"
android:drawable="#drawable/image_focused" />
</selector>
Also inspite of that you can use ImageButton which will keep your image in center of button and the effects will be default as per operating system.
I want make a list of Checkbox with white text in black background. We are using following code:
CheckBox chkAdditionalPack = new CheckBox(MainActivity.this);
chkAdditionalPack.setTag(j);
chkAdditionalPack.setText(offerPackageListForAddl.get(j).getOfferPackageName().toString());
chkAdditionalPack.setTextColor(Color.WHITE);
It gives a view like below:
The problem is now boxes of checkboxes is not clearly visible. How can I make it clearly visible keeping intact other parts?
If you are using android-studio, select your checkbox, and in the properties, set 'buttonTint' property value to whatever color you want using the editor. Or, if you prefer the XML solution, use
android:buttonTint="#color/white"
Note: This assumes that the color white is defined.
try the below xml code ref from solution
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_checked="true"
android:drawable="#drawable/cbchk_blue"
android:state_focused="false" >
</item>
<item
android:state_checked="true"
android:drawable="#drawable/cbchk_blue"
android:state_focused="true" >
</item>
<item
android:state_checked="false"
android:drawable="#drawable/cbunchk_blue"
android:state_focused="false" >
</item>
<item
android:state_checked="false"
android:drawable="#drawable/cbunchk_blue"
android:state_focused="true" >
</item>
</selector>
One really simple way to do it, within the xml for the checkbox, simply set the android:background variable to the colour you wish.
Instead of having the text and check box created together like this, simply create a custom list item layout xml file.
e.g custom_list_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#000000"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
/>
</LinearLayout>
Simply use this :
android:buttonTint="#FFFFFF"
** replace #FFFFFF with any color
Hi I have created a relative layout. and align the imageview to the right of relativelayout. I set the background of relativelayout using selector. if i select thye relativelayout its color wil be green otherwise its color will be white. Now I want to set the image depending on the selection of scrollview. If scrollview is selected then i want to show imge1 if not then i want to show image2. How can I achieve this?
main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/selector">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/arrow_right"
android:layout_alignParentRight="true" />
</RelativeLayout>
selector.xml
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_focused="true"
android:state_pressed="false"
android:drawable="#drawable/grbk" />
<item
android:state_focused="true"
android:state_pressed="true"
android:drawable="#drawable/grbk" />
<item
android:state_focused="false"
android:state_pressed="true"
android:drawable="#drawable/grbk" />
<item
android:drawable="#drawable/whbk" />
</selector>
Thanks
Sunil
In the same way as for background. You should add android:duplicateParentState="true"
<ImageView
android:duplicateParentState="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/arrow_selector"
android:layout_alignParentRight="true" />
first set the color to all the list list view item and then put the selector in the list view ..i gess u know how to set the selector in list view
We can create another selector for imageview and pass that selector as background to imageview.
imageselector.xml
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_focused="true"
android:state_pressed="false"
android:drawable="#drawable/arow_selected" />
<item
android:state_focused="true"
android:state_pressed="true"
android:drawable="#drawable/arow_selected" />
<item
android:state_focused="false"
android:state_pressed="true"
android:drawable="#drawable/arow_selected" />
<item
android:drawable="#drawable/arow_unselect" />
</selector>
main.xml
<ImageView
android:id="#+id/arrow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/imageselector"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="20dip"/>
</RelativeLayout>
Here is my suggestion..
once i set the background to the imageview, then when i want to change the transparent, i can do nothing...after check some website, i found i need to set the imageview's resourse instead of background...
