Text Gallery on Android?

Question

I have a gallery with the TextView to achieve the segment controller on the image below. I can achieve it by the ApiDemo's Gallery Example but I am lagging on the look and feel of the gallery.

I want to do the backgrounds, Selected/deselected and selected item won't be cone to the center of the screen.

Any Idea or Articles are most Thankful.

I have tried to get using 2 ways. that are:

1. Gallery View
2. horizontal ScrollView

The ouput getting is in the below image:

I have Problem on Both to get the proper output.

In Gallery View,

• can not Change Background of Selected Item.and make it us rounded corner.
• Selected Item comes to the center horizontal of the Screen Automatically.

In horizontal View,

• More Complicated when the textView's number is large.
• Can not find a way similar to On Click Item. if i have use switch case. the previous problem comes again.

Answer 1

place this in drawables text_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
    <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/round" />
    <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/round" />
    <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/round_selected" />
    <item android:drawable="@drawable/round" />
</selector>

round.xml

    <?xml version="1.0" encoding="UTF-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
     android:shape="rectangle"> 
     <gradient android:startColor="#FFEF95" android:endColor="#FFEF95"   
            android:angle="270"/> 
<corners android:bottomRightRadius="14dp" android:bottomLeftRadius="14dp" 
     android:topLeftRadius="14dp" android:topRightRadius="14dp"/> 

</shape>

round_selected.xml

<?xml version="1.0" encoding="UTF-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
     android:shape="rectangle"> 
     <gradient android:startColor="#F6A110" android:centerColor="#FFEF95" android:endColor="#F6A110"   
            android:angle="270"/> 
<corners android:bottomRightRadius="14dp" android:bottomLeftRadius="14dp" 
     android:topLeftRadius="14dp" android:topRightRadius="14dp"/> 

</shape>

And here is the textview to inflate

 <TextView    
        android:id="@+id/perioxi_select" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Select Area"
         android:gravity="center_vertical|center_horizontal"
         android:background="@drawable/text_selector"
         android:minHeight="60dp"
         style="@style/FirstText"   
         android:layout_weight="1"
        />

Get the style too. should be placed inside res/valus/styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources> 
 <style name="FirstText"> 
        <item name="android:colorForeground">#f0f</item> 
        <item name="android:padding">4sp</item> 
        <item name="android:textSize">15sp</item> 
        <item name="android:textColor">#CC3300</item> 
        <item name="android:gravity">left</item> 
        <item name="android:typeface">monospace</item> 
        <item name="android:textStyle">bold</item> 
        <item name="android:colorBackground">#999</item> 
    </style> 
  </resources>
