Android ActionBar Tab Color

For anyone wants to change actionbar color/background in code, you can do something like this

final ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(getResources().getDrawable(R.drawable.action_bar_bg));

To change the tab bar color under the actionbar:

actionBar.setStackedBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.color_brown_dark)));

To change tab bar background:

actionBar.setStackedBackgroundDrawable(getResources().getDrawable(
            R.drawable.coupon_header));

GridView with Auto Resized Images on Android

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:verticalSpacing="0dp"
        android:horizontalSpacing="0dp"
        android:stretchMode="columnWidth"
        android:numColumns="2" />
</FrameLayout>

package com.rogcg.gridviewexample;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;

public class SquareImageView extends ImageView
{
    public SquareImageView(Context context)
    {
        super(context);
    }

    public SquareImageView(Context context, AttributeSet attrs)
    {
        super(context, attrs);
    }

    public SquareImageView(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
       Context context=getContext();
     
     WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
     Display display = wm.getDefaultDisplay();
     
     Point size = new Point();
     display.getSize(size);
     int width = size.x;
     int height = size.y-80;

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        //setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth()); //Snap to width
        if(Config.orientation==1)
        setMeasuredDimension(getMeasuredWidth(), height/3); //Snap to width
        else
         setMeasuredDimension(getMeasuredWidth(), height/2); //Snap to width   }
}



And now we make a layout for a grid item using this SquareImageView class and set the scaleType to centerCrop. Let's call this filegridview_item.xml.

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <com.rogcg.gridviewexample.SquareImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"
        />
    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:paddingBottom="15dp"
        android:layout_gravity="bottom"
        android:textColor="@android:color/white"
        android:background="#55000000"
        />
</FrameLayout>
