How to force the View Pager to wrap its content.

The problem is that the "wrap_content" doesn't seem to be working with the View pager.
Here is the solution:

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.View;

public class CustomViewPager extends ViewPager {

    public CustomViewPager(Context context) {
        super(context);
    }

public CustomViewPager(Context context, AttributeSet attrs){

        super(context, attrs);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        int height = 0;
        for(int i = 0; i < getChildCount(); i++) {

            View child = getChildAt(i);

            child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));

            int h = child.getMeasuredHeight();

            if(h > height) height = h;

        }

        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}

Dimming the background behind the dialogs

I'm just reblogging what you can find here.

WindowManager.LayoutParams lp = dialog.getWindow().getAttributes(); 
lp.dimAmount=0.78f; 
dialog.getWindow().setAttributes(lp); 
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

That's it, don't hesitate to comment, to share your knowledge and to correct me.
