Enabling USB debugging on your phone

Coming here after a very very long time.

Today let us see how to become a developer.

I am kidding. Let us talk about how to enable your device to be connected for debugging in android studio.

You need to install a samsung adb driver for your laptop first of all. Or which phone your brand is.

Next take your phone - go to

Settings
About Device
Build Number - tap on this like 10 times. And your phone tells you now you are a developer.

Great isn't it. No studying needed.

Do you see your phone in android studio, when you connect to through usb? No, not yet.

Because there is one more step to be done.

Now settings has Developer options in it.

Goto

Settings
Developer Options
USB debugging - check on this

Done !!! Now you can debug your android app on your phone.

When you are using a listview in your applications many a times you will write your own adapter to display item. But if your list is very simple showing a list of strings, you can use inbuilt adapters like ArrayAdapter, SimpleCursorAdapter etc.

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ListView android:layout_height="wrap_content" android:id="@+id/listView1" android:layout_width="match_parent" android:layout_margin="20dp"> </ListView> </LinearLayout>

DatePickers in Android

DatePicker is a view which lets the user select a date showing a calendar or 3 spinners for dd, mm and yy.
