My app is loading the start page in 10 seconds. In that time of 10 sec android screen is blank.
In that time I want to add the loading screen. How to add it?
And tell me in app how to know the starting page is loading? And tell me how to do in my app?
use ProgressDialog.
ProgressDialog dialog=new ProgressDialog(context);
dialog.setMessage("message");
dialog.setCancelable(false);
dialog.setInverseBackgroundForced(false);
dialog.show();
hide it whenever your UI is ready with data. call :
dialog.hide();
You can use splash screen in your first loading Activity like this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread welcomeThread = new Thread() {
#Override
public void run() {
try {
super.run();
sleep(10000); //Delay of 10 seconds
} catch (Exception e) {
} finally {
Intent i = new Intent(SplashActivity.this,
MainActivity.class);
startActivity(i);
finish();
}
}
};
welcomeThread.start();
}
Hope this code helps you.

Splash screens just waste your time, right? As an Android developer,
when I see a splash screen, I know that some poor dev had to add a
three-second delay to the code.
Then, I have to stare at some picture for three seconds until I can
use the app. And I have to do this every time it’s launched. I know
which app I opened. I know what it does. Just let me use it!
Splash Screens the Right Way
I believe that Google isn’t contradicting itself; the old advice and
the new stand together. (That said, it’s still not a good idea to use
a splash screen that wastes a user’s time. Please don’t do that.)
However, Android apps do take some amount of time to start up,
especially on a cold start. There is a delay there that you may not be
able to avoid. Instead of leaving a blank screen during this time, why
not show the user something nice? This is the approach Google is
advocating. Don’t waste the user’s time, but don’t show them a blank,
unconfigured section of the app the first time they launch it, either.
If you look at recent updates to Google apps, you’ll see appropriate
uses of the splash screen. Take a look at the YouTube app, for
example.
You can create a custom loading screen instead of splash screen. if you show a splash screen for 10 sec, it's not a good idea for user experience. So it's better to add a custom loading screen. For a custom loading screen you may need some different images to make that feel like a gif. after that add the images in the res folder and make a class like this :-
public class LoadingScreen {private ImageView loading;
LoadingScreen(ImageView loading) {
this.loading = loading;
}
public void setLoadScreen(){
final Integer[] loadingImages = {R.mipmap.loading_1, R.mipmap.loading_2, R.mipmap.loading_3, R.mipmap.loading_4};
final Handler loadingHandler = new Handler();
Runnable runnable = new Runnable() {
int loadingImgIndex = 0;
public void run() {
loading.setImageResource(loadingImages[loadingImgIndex]);
loadingImgIndex++;
if (loadingImgIndex >= loadingImages.length)
loadingImgIndex = 0;
loadingHandler.postDelayed(this, 500);
}
};
loadingHandler.postDelayed(runnable, 500);
}}
In your MainActivity, you can pass a to the LoadingScreen class like this :-
private ImageView loadingImage;
Don't forget to add an ImageView in activity_main.
After that call the LoadingScreen class like this;
LoadingScreen loadingscreen = new LoadingScreen(loadingImage);
loadingscreen.setLoadScreen();
I hope this will help you
public class Splash extends Activity {
private final int SPLASH_DISPLAY_LENGHT = 3000; //set your time here......
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
new Handler().postDelayed(new Runnable(){
#Override
public void run() {
/* Create an Intent that will start the Menu-Activity. */
Intent mainIntent = new Intent(Splash.this,MainActivity.class);
Splash.this.startActivity(mainIntent);
Splash.this.finish();
}
}, SPLASH_DISPLAY_LENGHT);
}
}
If the application is not doing anything in that 10 seconds, this will form a bad design only to make the user wait for 10 seconds doing nothing.
If there is something going on in that, or if you wish to implement 10 seconds delay splash screen,Here is the Code :
ProgressDialog pd;
pd = ProgressDialog.show(this,"Please Wait...", "Loading Application..", false, true);
pd.setCanceledOnTouchOutside(false);
Thread t = new Thread()
{
#Override
public void run()
{
try
{
sleep(10000) //Delay of 10 seconds
}
catch (Exception e) {}
handler.sendEmptyMessage(0);
}
} ;
t.start();
//Handles the thread result of the Backup being executed.
private Handler handler = new Handler()
{
#Override
public void handleMessage(Message msg)
{
pd.dismiss();
//Start the Next Activity here...
}
};
Write the code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread welcomeThread = new Thread() {
#Override
public void run() {
try {
super.run();
sleep(10000) //Delay of 10 seconds
} catch (Exception e) {
} finally {
Intent i = new Intent(SplashActivity.this,
MainActivity.class);
startActivity(i);
finish();
}
}
};
welcomeThread.start();
}

I have a scenario, which when a User Rating, or inputting on a data, then the current Activity will Time it to the setted time.
So, if the User isn't do Anything, or taking the Action to Long, then the current Activity will direct the User into the MainActivity.
In my case, i have a Rating app, which is located in a Public place. I thought that if People wants to Rate BUT not completing the Quiz phase, then i don't want to leave the last Quiz to meet the new People who wants to Rate.
I've tried using these code:
int timeout = 4000;
Timer timer = new Timer();
timer.schedule(new TimerTask() {
#Override
public void run() {
Intent homepage = new Intent(Quiz2.this, MainActivity.class);
startActivity(homepage);
finish();
}
}, timeout);
And these one:
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
startActivity(new Intent(Quiz2.this, MainActivity.class));
}
}, 4000);
It works, but it didn't work as expected, as it apply to ALL of the activities (I mean, after these code works in Current Activity, the Rest of the Activities is Applied and Timed too)
I don't want this. What i want is to Apply these Timer ONLY in Current Activity.
How this can be done?
Appreciate for any help, Regards.
I didn't fully understand what you actually wanna do,
but I'm guessing using CountDownTimer and then starting the other activity when the timer finished should do the trick.
new CountDownTimer(4000, 1000) {
public void onTick(long millisUntilFinished) {
// You could show the user the time left using `millisUntilFinished`
}
public void onFinish() {
// Do something when the timer is finished (start your activity & finish)
}
}.start();
I am having a application which have a splash screen. My problem is i need a splash screen with the pinwheel spinner(progress bar). I have also added the android java code.
Java code
package com.SSF;
import android.os.Bundle;
import android.widget.Toast;
import com.worklight.androidgap.WLDroidGap;
public class SSF extends WLDroidGap {
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
}
/**
* onWLInitCompleted is called when the Worklight runtime framework initialization is complete
*/
#Override
public void onWLInitCompleted(Bundle savedInstanceState){
super.loadUrl(getWebMainFilePath());
// Add custom initialization code after this line
}
}
Having a splash screen is redundant, and should be avoided unless maybe it's the first run of the app. Users like to open the app and start using it right away.
Only really heavy apps (mostly games ) need to load a lot of things, but even there, there are plenty of optimizations to make it short (just load what it needs in the near future, for example).
Anyway, for the progress bar, just create a layout with a progress bar view in the middle, use "setContentView" on it, and that's it...
You can also customize the progress bar by yourself, for example using this post.
You can try this code. please
public class MainActivity extends Activity {
private ImageView splashImageView;
boolean splashloading = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
splashImageView = new ImageView(this);
splashImageView.setScaleType(ScaleType.FIT_XY);
splashImageView.setImageResource(R.drawable.ic_launcher);
setContentView(splashImageView);
// interesting music
/**
* Gets your sound file from res/raw
*/
splashloading = true;
Handler h = new Handler();
h.postDelayed(new Runnable() {
public void run() {
splashloading = false;
setContentView(R.layout.activity_main);
}
}, 3000);
}
Best of luck!
try below code:-
// METHOD 1
/****** Create Thread that will sleep for 5 seconds *************/
Thread background = new Thread() {
public void run() {
try {
// Thread will sleep for 5 seconds
// show progress bar here
sleep(5*1000);
// After 5 seconds redirect to another intent
Intent i=new Intent(getBaseContext(),FirstScreen.class);
startActivity(i);
//Remove activity
finish();
// hide progress bar here
} catch (Exception e) {
}
}
};
// start thread
background.start();

http://www.androidhive.info/2013/07/how-to-implement-android-splash-screen-2/
Up until Worklight 6.2 it was not possible to customize the splash screen in a Worklight-based Android application, be it adding a spinner, extending the time the splash is displayed or creating an entirely customized experienced.
Starting Worklight 6.2 the entire flow is customizable if the developer so chooses. This is documented at: Managing the splash screen in an Android-based hybrid application, which also provides various code examples.
BTW, you already asked about this... Splash Screen with loading in four environment(android,ios,blackberry and windows) using html coding or common plugin for hybrid apps
Iam an newbie to android.I don't know whether this question may sound silly but i didn't find any solution.Please bare me. I had created an application which will first loads the app logo. I need to call another activity after this without using any click event.can anybody help me out wit this? and also i need to know in windows we can place panels over another panel. Can we do the same ting android? If yes how can i achieve that? I know that in a layout we have to place views but my questions is can we design view over another view so that i can hide and show views whenever needed?
Thanks in advance
Using Timers or Threads is a horrible way to do this, you are inviting memory leaks into your app. Use Android's Handler instead:
Handler handler = new Handler();
handler.postDelayed(new Runnable()
{
#Override
public void run()
{
// create Intent for next activity and call startActivity with it
}
}, 2000);
If you have a reference to your content view, use contentView.getHandler() instead of creating a new one.
By the way, if this is for a personal project, consider NOT USING SPLASH SCREENS
You do not really provide enough information to give you a proper answer, but this will start a timer and when 5000 milliseconds has elapsed it will switch to another activity:
public class SplashActivity extends Activity {
private Timer t;
public void onCreate(Bundle b) {
super.onCreate(b);
t = new Timer();
t.schedule(new TimerTask() {
#Override
public void run() {
Intent i = new Intent(SplashActivity.this, NextActivity.class);
startActivity(i);
}
}, 5000);
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.welcome);
Thread timer = new Thread() {
public void run() {
try {
sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
Intent intent = new Intent();
intent.setClass(WelcomePage.this, HomePage.class);
startActivity(intent);
}
}
};
timer.start();
}
that should do the trick my friend!!
All! I am pretty new to Developing Android. I have run into many issues already and solved most of them myself, and some by searching here and on other sites. The problem I currently face now, I can't seem to find a solution for. It is close to what others on here have asked, but I can't find anything for my problem.
I am working on the beginning stages of my first big app, in which a user signs in to the fist page and is then allowed access to the rest of the app and features with. I am using basic examples right now of a simple log in app and it works fine, but when I try to delay the first activity from calling the second one until the results are posted, either it posts and doesn't call the second activity, or it doesn't post the results and moves on anyways. I am also currently trying to bundle the results and display them in the second activity. I Will change that later though, I just need to see if it will work right.
Here is my code:(not sure if I'm doing this right. It's my first time!)
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Login button clicked
ok = (Button)findViewById(R.id.btn_login);
ok.setOnClickListener(this);
result = (TextView)findViewById(R.id.lbl_result);
final Handler handler1 = new Handler();
handler1.postDelayed(new Runnable() {
#Override
public void run() {
ok.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final Bundle b = new Bundle();
EditText txt1 = (EditText)findViewById(R.id.editText1);
EditText txt2 = (EditText)findViewById(R.id.lbl_result);
b.putString("ID", txt1.getText().toString());
b.putString("PW", txt2.getText().toString());
final Handler handler2 = new Handler();
handler2.postDelayed(new Runnable() {
#Override
public void run() {
final Intent myIntent = new Intent(TempActivity.this, TempActivity2.class);
myIntent.putExtras(b);
startActivity(myIntent);
}
}, 3000);
}
});
}
}, 4000);
}
Am I just going about this the wrong way? Any help is greatly appreciated! I hate being a noob! Let me know if anymore information is needed!
Ohhhh... i dont know.. if it is actually right.. but as far as i understand your code... you are using
handler1.postDelayed(new Runnable() {
and in its runnable
public void run() {
ok.setOnClickListener(new View.OnClickListener() {
here.. you are setting onClickListener.. and it will happen after 4 seconds.. because of this line..
}, 4000);
so if you click before 4 seconds.. i think onclicklistener is not being set... so give some time.. like 4 seconds after the application starts
.. and then try clicking... i think then it should work..
I'm trying to create a ProgressDialog for an Android-App (just a simple one showing the user that stuff is happening, no buttons or anything) but I can't get it right. I've been through forums and tutorials as well as the Sample-Code that comes with the SDK, but to no avail.
This is what I got:
btnSubmit.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
(...)
ProgressDialog pd = new ProgressDialog(MyApp.this);
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pd.setMessage("Working...");
pd.setIndeterminate(true);
pd.setCancelable(false);
// now fetch the results
(...long time calculations here...)
// remove progress dialog
pd.dismiss();
I've also tried adding pd.show(); and messed around with the parameter in new ProgressDialog resulting in nothing at all (except errors that the chosen parameter won't work), meaning: the ProgressDialog won't ever show up. The app just keeps running as if I never added the dialog.
I don't know if I'm creating the dialog at the right place, I moved it around a bit but that, too, didnt't help. Maybe I'm in the wrong context? The above code is inside private ViewGroup _createInputForm() in MyApp.
Any hint is appreciated,
you have to call pd.show before the long calculation starts and then the calculation has to run in a separate thread. A soon as this thread is finished, you have to call pd.dismiss() to close the prgoress dialog.
here you can see an example:
the progressdialog is created and displayed and a thread is called to run a heavy calculation:
#Override
public void onClick(View v) {
pd = ProgressDialog.show(lexs, "Search", "Searching...", true, false);
Search search = new Search( ... );
SearchThread searchThread = new SearchThread(search);
searchThread.start();
}
and here the thread:
private class SearchThread extends Thread {
private Search search;
public SearchThread(Search search) {
this.search = search;
}
#Override
public void run() {
search.search();
handler.sendEmptyMessage(0);
}
private Handler handler = new Handler() {
#Override
public void handleMessage(Message msg) {
displaySearchResults(search);
pd.dismiss();
}
};
}
I am giving you a solution for it,
try this...
First define the Progress Dialog in the Activity before onCreate() method
private ProgressDialog progressDialog;
Now in the onCreate method you might have the Any button click on which you will change the Activity on any action. Just set the Progress Bar there.
progressDialog = ProgressDialog.show(FoodDriveModule.this, "", "Loading...");
Now use thread to handle the Progress Bar to Display and hide
new Thread()
{
public void run()
{
try
{
sleep(1500);
// do the background process or any work that takes time to see progress dialog
}
catch (Exception e)
{
Log.e("tag",e.getMessage());
}
// dismiss the progress dialog
progressDialog.dismiss();
}
}.start();
That is all!
Progress Dialog doesn't show because you have to use a separated thread. The best practices in Android is to use AsyncTask ( highly recommended ).
See also this answer.
This is also possible by using AsyncTask. This class creates a thread for you. You should subclass it and fill in the doInBackground(...) method.
