Android realizes the switch between the splash screen and the registration and login interface _android

Before we introduce the text to everyone to say the realization of ideas:

First, respectively, the implementation of the splash screen, registration interface, login interface activities, and then use intent related activities connected to achieve the jump between different activities. This trial code more, I only listed the main code, detailed code can be downloaded from the bottom of the download link.

First, the Experiment Effect chart:

Second, the main code:

(1) Welcomeactivity.java (this part of the code to achieve the first page of the Welcome page)

Package Com.example.flashscreendemo; 
Import android.app.Activity; 
Import android.content.Intent; 
Import Android.os.Bundle; 
Import android.view.animation.AlphaAnimation; 
Import android.view.animation.Animation; 
Import Android.view.animation.Animation.AnimationListener; 
Import android.view.animation.RotateAnimation; 
Import Android.widget.ImageView; 
Import Android.widget.RelativeLayout; 
public class Weclomeactivity extends activity {private relativelayout layoutwecome; 
Private ImageView Ivmonkey; 
@Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); * * * requestwindowfeature (Window.feature_no_title); Cancel the Power status bar * This.getwindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, * 
WindowManager.LayoutParams.FLAG_FULLSCREEN); 
* * Setcontentview (r.layout.activity_weclome); 
Layoutwecome = (relativelayout) Findviewbyid (r.id.layoutwelcome); 
Alphaanimation alphaanimation = new Alphaanimation (0.0f, 1.0f); Alphaanimation.setdUration (1000); 
Layoutwecome.startanimation (alphaanimation); 
Ivmonkey = (ImageView) Findviewbyid (R.id.ivmonkey); 
Rotateanimation rotateanimation = new Rotateanimation (0, 360); 
Rotateanimation.setduration (2000); 
Rotateanimation.setrepeatcount (2); 
Ivmonkey.startanimation (rotateanimation); Rotateanimation.setanimationlistener (New Animationlistener () {@Override public void Onanimationstart (Animation Animation) {} @Override public void Onanimationrepeat (animation animation) {} @Override public void Onanimationend (Animation Animation) 
{Intent Intent = new Intent (weclomeactivity.this, Guideactivity.class); 
StartActivity (Intent); 
Finish (); 
} 
}); } 
}

(2) Guideactivity.java (this part of the code implements the functionality of the four boot interfaces)

Package Com.example.flashscreendemo; 
Import java.util.ArrayList; 
Import java.util.List; 
Import Com.example.flashscreendemo.adapter.GuideAdapter; 
Import android.app.Activity; 
Import android.content.Intent; 
Import Android.os.Bundle; 
Import Android.support.v4.view.ViewPager; 
Import Android.support.v4.view.ViewPager.OnPageChangeListener; 
Import Android.view.LayoutInflater; 
Import Android.view.Menu; 
Import Android.view.View; 
Import Android.widget.ImageView; 
public class Guideactivity extends activity {private Viewpager vpguide; 
Private ImageView ivdots[]; 
Private int[] dots_id; 
@Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); 
Setcontentview (R.layout.activity_guide); 
Initguideviews (); 
Initdots (); Vpguide.setonpagechangelistener (New Onpagechangelistener () {@Override public void onpageselected (int position) {for ( int i = 0; i < ivdots.length; i++) {if (position = = i) {ivdots[i]. Setimageresource (r.drawable.bg_point_selected); 
else {ivdots[i].setimageresource (r.drawable.bg_point_normal); @Override public void onpagescrolled (int position, float arg1, int arg2) {} @Override public void Onpagescro 
llstatechanged (int postion) {}}); public void Jumpmain (view view) {Intent Intent = new Intent (This, Com.example.minitwittersimulate.LoginActivity.clas 
s); 
StartActivity (Intent); 
Finish (); 
} private void Initdots () {dots_id = new int[] {r.id.ivdots1, r.id.ivdots2, R.id.ivdots3, R.ID.IVDOTS4}; 
Ivdots = new Imageview[dots_id.length]; 
for (int i = 0; i < ivdots.length i++) {ivdots[i] = (ImageView) Findviewbyid (dots_id[i)); 
} private void Initguideviews () {vpguide = (Viewpager) Findviewbyid (r.id.vpguide); 
list<view> views = new arraylist<view> (); 
Layoutinflater layoutinflater = Getlayoutinflater (); 
View view1 = layoutinflater.inflate (R.layout.view1ofpager, NULL); 
Views.add (View1); View view2 = layoutinflater.inflate (R.LAYOUT.VIEW2OFPAGER, NULL); 
Views.add (VIEW2); 
View view3 = layoutinflater.inflate (R.layout.view3ofpager, NULL); 
Views.add (VIEW3); 
View view4 = layoutinflater.inflate (R.layout.view4ofpager, NULL); 
Views.add (VIEW4); 
Guideadapter guideadapter = new Guideadapter (views); 
Vpguide.setadapter (Guideadapter); @Override public boolean Oncreateoptionsmenu (Menu menu) {//Inflate the menu; This adds the items to the action bar if I 
T is present. 
Getmenuinflater (). Inflate (r.menu.guide, menu); 
return true; } 
}

(3) Guideadapter.java (this part of the code to achieve the function of data adaptation)

Package com.example.flashscreendemo.adapter; 
Import java.util.List; 
Import Android.support.v4.view.PagerAdapter; 
Import Android.view.View; 
Import Android.view.ViewGroup; 
public class Guideadapter extends Pageradapter { 
private list<view> views; 
Public Guideadapter (list<view> views) { 
super (); 
This.views = views; 
} 
@Override public 
int GetCount () {return 
views.size (); 
} 
@Override Public 
Boolean isviewfromobject (View view, Object object) {return 
view = = object; 
} 
@Override public 
Object instantiateitem (viewgroup container, int position) { 
Container.addview views.get ( position)); 
return Views.get (position); 
} 
@Override public 
void Destroyitem (ViewGroup container, int position, object object) { 
Container.removeview ( Views.get (position)); 
} 

(4) Loginactivity.java (this part of the code is the implementation of the login interface)

Package com.example.minitwittersimulate; 
Import android.app.Activity; 
Import android.content.Intent; 
Import android.content.SharedPreferences;

Import Android.widget.Toast; 
Import COM.EXAMPLE.FLASHSCREENDEMO.R; 
public class Loginactivity extends activity {private sharedpreferences pref; 
Private Sharedpreferences.editor Editor; 
Private EditText Etusername; 
Private EditText Etpassword; 
Private Button Btnlogin; 
Private CheckBox Cbrememberpass; 
Private TextView Tvre; 
@Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); 
Setcontentview (R.layout.activity_login); 
Pref = Preferencemanager.getdefaultsharedpreferences (this); Etusername = (edittext) Findviewbyid (R.Id.etusername); 
Etpassword = (edittext) Findviewbyid (R.id.etpassword); 
Cbrememberpass = (CheckBox) Findviewbyid (R.id.cbrememberpass); 
Btnlogin = (Button) Findviewbyid (R.id.btnlogin); 
Tvre = (TextView) Findviewbyid (R.id.tvre); 
Boolean isremember = Pref.getboolean ("Remember_password", false); 
if (isremember) {//The account number and password are set to the text box = pref.getstring ("Accounts", ""); 
String Password = pref.getstring ("Password", ""); 
Etusername.settext (account); 
Etpassword.settext (password); 
Cbrememberpass.setchecked (TRUE); Btnlogin.setonclicklistener (New Onclicklistener () {@Override public void OnClick (View v) {String account = Etusern 
Ame.gettext (). toString (); 
String password = Etpassword.gettext (). toString (); if (Account.trim (). Equals ("")) {Toast.maketext (loginactivity.this, "Please enter your username!") 
", Toast.length_short). Show (); 
Return } if (Password.trim (). Equals ("")) {Toast.maketext (loginactivity.this, "Please enter your password!") 
", Toast.length_short). Show (); 
Return } if (Account.equals ("Admin ") && password.equals (" 123456 ")) {editor = Pref.edit (); 
if (cbrememberpass.ischecked ()) {//Check check box is selected Editor.putboolean ("Remember_password", true); 
Editor.putstring ("account", account); 
Editor.putstring ("password", password); 
else {editor.clear (); 
} editor.commit (); 
Intent Intent = new Intent (loginactivity.this, Mainactivity.class); 
StartActivity (Intent); 
Finish (); 
else {toast.maketext (loginactivity.this, "account or password be invalid", Toast.length_short). Show (); 
} 
} 
}); Tvre.setonclicklistener (New Onclicklistener () {@Override public void OnClick (View v) {//TODO auto-generated method s 
Tub Intent Intent = new Intent (loginactivity.this, Register.class); 
StartActivity (Intent); 
Finish (); 
} 
}); } 
}

(5) User.java (this part of the code implements data entered into user input to the registration interface)

Package com.example.minitwittersimulate; 
public class User {private String userName; 
Private String PassWord; 
private char sex; 
Private String City; 
Private String hobby; 
Public String GetUserName () {return userName; 
} public void Setusername (String userName) {this.username = UserName; 
Public String GetPassword () {return passWord; 
} public void SetPassword (String passWord) {This.password = PassWord; 
Public Char Getsex () {return sex; 
The public void setsex (char sex) {this.sex = sex; 
Public String getcity () {return city; 
public void Setcity (String city) {this.city = city; 
Public String Gethobby () {return hobby; 
} public void Sethobby (String hobby) {this.hobby = hobby; 
Public User (String userName, string passWord, char sex, String city, String hobby) {super (); 
This.username = UserName; 
This.password = PassWord; 
This.sex = sex; 
this.city = City; 
This.hobby = hobby; @Override public String toString () {//TODO Auto-genErated method stubs return this.username + "," + This.password + "," + This.sex + "," + this.city + "," + this.hobby; } 
}

(6) Register.java (this part of the code is the implementation of the registration Interface)

Package com.example.minitwittersimulate; 
Import COM.EXAMPLE.FLASHSCREENDEMO.R;

Return 
String REPASSW = Etrepassw.gettext (). toString (); 
if (Textutils.isempty (REPASSW)) {etrepassw.seterror ("Confirm password cannot be blank"); 
Return 
} if (!passw.equals (REPASSW)) {Toast.maketext (this, "two times password inconsistency,"). Show (); 
Return 
} char sex; 
if (rbmale.ischecked ()) {sex = Rbmale.gettext (). charAt (0); 
else {sex = Rbfamale.gettext (). charAt (0); 
} stringbuffer s = new StringBuffer (); 
if (cbread.ischecked ()) {S.append (Cbread.gettext (). toString () + ","); 
} if (cbtourist.ischecked ()) {S.append (Cbtourist.gettext (). toString () + ","); 
} if (cbplaygame.ischecked ()) {S.append (Cbplaygame.gettext (). toString () + ","); 
String city = Spcity.getselecteditem (). toString (); 
User user = new User (userName, PASSW, Sex, s.tostring (). Equals ("")? ": s.tostring (). substring (0, s.length ()), city); 
Toast.maketext (This, "User registration information:" + user.tostring (), 100000). Show (); 
Intent Intent = new Intent (register.this, Loginactivity.class); 
StartActivity (Intent); 
Finish (); 
Break 
Case R.id.bteixt:finish (); 
Break 
Case R.id.btreturn:intent intent1 = new Intent (register.this, Loginactivity.class); 
StartActivity (INTENT1); 
Finish (); 
Break } 
} 
}

(7) Mainactivity.java (this part of the code to achieve the click "Login" button to jump to the interface)

Package com.example.minitwittersimulate; 
Import android.app.Activity; 
Import Android.os.Bundle; 
Import Android.view.Menu; 
Import COM.EXAMPLE.FLASHSCREENDEMO.R; 
public class Mainactivity extends activity { 
@Override 
protected void onCreate (Bundle savedinstancestate) { 
super.oncreate (savedinstancestate); 
Setcontentview (R.layout.activity_main); 
} 
@Override Public 
Boolean oncreateoptionsmenu (Menu menu) { 
getmenuinflater (). Inflate (R.menu.main, menu); 
return true; 
} 

The above is a small set of Android to introduce the screen and registration and login interface between the switch effect, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
