Android Studio Project: Outside News

The previous projects I have made are mainly about logical thinking. Today, I share this project, Outside News to all of you, which is full of beautiful user interfaces. I'm sorry that it's only a demo without news recources and strong features. If you want to have a try, just do it!

Is this project with the use of Viewpager, ListView, PopupWindow, PopupMenu and many other views more colorful? What's more, it uses SharedPreferences and SQLite database to store some data persistently. And it involves multithread programming and asynchronous message processing. The use of vector is also one of my harvests.

Android Learning Note: To Set The Color Of Cursor The Same As Text Color In An EditText

To set the color of cursor the same as text color in an EditText, just add a sentence in the layout file like this:

 android:textCursorDrawable="@null"

"@null" here means the color of cursor is the same with the text. It's said that you can change it as you like to set the color arbitrarily. You may have a try.

Android Learning Note: To Delete The Default Bottom Line Of EditText

To delete the default bottom line of EditText, just add the following sentence in the layout file, of course, between "<EditText" and "/>".

android:background="@null"

Android Learning Note: Never Set 2 Different Layout To 1 Activity

This is the original post of mine, which is wrong in fact.

Just add the following codes behind "super.onCreate(savedInstanceState);" sentence in the onCreate(Bundle savedInstanceState) methed of the main Activity.

//Entering Splash Screen. Here I use the layout file welcome.xml

setContentView(R.layout.welcome);

// Creating a Handler object and operate it like this. You may set another waiting time

new Handler() {
    @Override    public void handleMessage(Message msg) {
        setContentView(R.layout.activity_main);
    }
}.sendEmptyMessageDelayed(1,2000);

After short enjoyness, I got into trouble caused by the codes below. Crap say no more, I used the methed setContentView() twice in the codes below, which caused serious NullPointerException in the following codes.

Maybe this is a stupid mistake for many of you, I thgink it valuable for me, for I have debuged the program and resulted others to make sense of it. And I'm impressed on this error, believing that I'll never make this kind of mistake.
