Set two buttons to same width regardless of screen size

Use android:layout_weight="1" on both Buttons. Set android:layout_width="0dp" on both. Since both buttons now have equal weighting, they will now each have half the parent's width.

Transfer contacts from iphone to Android

If you’ve enabled the iCloud service on your iPhone, your phone contacts have most likely been backed up to your iCloud account.  You can then export those contacts into a file that can be imported into Android directly, or indirectly through Google Contacts.

1. Using your desktop Internet browser, go to https://www.icloud.com/ and sign in with your iCloud account.
2. Click Contacts to view a list of contacts.
3. Select the contact(s) that you want to export.
4. Click the cog wheel icon at the lower left and select Export vCard.
5. Your computer will download a VCF file containing the exported contact(s).
6. Import this VCF file to Google Contacts or copy the VCF to your Android phone’s /sdcarddirectory and import it to your phone through the People app or Contacts app.
