How to set transparent background for image button, text edit, etc on android project.

When you want to change layout like that, somepeople add some code on file.java, but I have simple trick to change background of image button or EditText to transparant, it easy...you can add it's code android:background="#00ffffff" to your file.xml example:

Before:
<EditText
        android:id="@+id/I1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_x="1dp"
        android:layout_y="86dp"
        android:ems="10"
        android:gravity="center"
        android:hint="Input First Number"
        android:numeric="integer"
        android:textColorHint="#FAFAD2"
        android:textColor="#FAFAD2" />

After:
<EditText
        android:id="@+id/I1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_x="1dp"
        android:layout_y="86dp"
        android:background="#00ffffff"
        android:ems="10"
        android:gravity="center"
        android:hint="Input First Number"
        android:numeric="integer"
        android:textColorHint="#FAFAD2"
        android:textColor="#FAFAD2" />

save and run your project, and see the magic :D
okay...#keep coding, and be a programmer....

How To Change CPU Cores on LINUX

 Multicore Processor

 

 

Opinion:

Some choose to use a single core or one processor core reasons:

• Computer only used for lightweight applications such as Internet browsing, office applications

• 1 core processors more power efficient.

• Single core is enough for me at this time.

I got it on other blog :)

Some people choose to use a single core:

• Computer only used for lightweight applications such as Internet browsing, office applications.
• 1 core processors more power efficient.
• Single core is enough.

Some people choose to use a dual core:

• dual core processor is more intensive for gaming applications.
• Speed ​​is not much different dual core quad cores for specific applications.
• Got a dual core processor speed better at the same price of a quad core.
• Power is more efficient than quad core.

hmmm... I also chose dualcore because, I think is helpful me,  for improving performance of the emulator. when I run to try a app of android have I created.
and how to change it, yeaah like that...

Method 1:
This method is dynamic and doesn’t require a reboot. You can just open a terminal and try this out:

• sudo sh -c "echo 0 > /sys/devices/system/cpu7/online" sudo sh -c "echo 0 > /sys/devices/system/cpu6/online"

  Repeat the above steps for cpu2 to cpu7 and it’ll leave you with cpu0 and cpu1 active which is essentially what we’re trying to achieve.

Method 2:
I like it and working to me....This method will make the linux boot with 2 cores which might make kernel more optimized for dual core environment than the method above.

• Add maxcpus=2 to GRUB command line by doing the following:

  gksu gedit /etc/default/grub

  Find:
  

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

  and change it to
  

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash maxcpus=2"

• Then run:

  sudo update-grub

  When you reboot, linux will run on 2 cores.
  
  ok...see u next time, #keep coding programmer...

when you have a problem same with me, because of "You don't install CPU System Images. for example: ARM EABI v7a System Image" and then i installing a cpu system image on sdk manager. I'm click the icon Android SDK manager on toolbar and i go to Android 4.1.2 API Level 16 and i checklist a cpu system image for download and installing it.

and finally, i can to create a android emulator 4.1 :D don't you believe me? let's try it's your home and see the magic :v ckckck.... i hope this can help you to solve your problems #keep coding programmer ;)
