How to display another activity?
I want to display one activity which has one Image View splash displaying an image. I want to display that just for 5 seconds then move on to another activity.splash is displaying in emulator but another activity menu is not displaying.
Here is my code:
com.basic.android;
import java.util.Timer;
import java.util.TimerTask;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
public class androidbasics extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
}
public void toCallActivity() {
TimerTask startNewActivity;
final Handler handler = new Handler();
final Timer timer = new Timer();
startNewActivity = new TimerTask() {
#Override
public void run() {
// TODO Auto-generated method stub
handler.post(new Runnable() {
public void run() {
try {
timer.cancel();
startActivity(new Intent(androidbasics.this,menu.class));
} catch (Exception e) {
// TODO Auto-generated catch block
}
}
});
}
};
timer.schedule(startNewActivity, 0,5000);
}
}
You didn't call toCallActivity().So your new Activity is not coming in the front.Write like this.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
toCallActivity();
}
try this ....
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
BackgroundTask b = new BackgroundTask();
b.execute("Main");
}
/** Called when the activity is first created. */
class BackgroundTask extends AsyncTask<String , Void, Void>
{
#Override
protected void onPreExecute()
{
setContentView(R.layout.splash);
}
#Override
protected Void doInBackground(String... params)
{
// TODO Auto-generated method stub
int pause=5000;
int interval =1000;
int counter=0;
while(counter<pause)
{
try
{
Thread.sleep(interval);
counter+=interval;
}
catch(Exception e)
{
System.out.println(e);
}
}
return null;
}
#Override
protected void onPostExecute(Void result)
{
startActivity( new Intent(androidbasics.this,menu.class));
androidbasics.this.finish();
}
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Thread splashTread = new Thread() {
#Override
public void run() {
try {
int waited = 0;
while(_active && (waited < _splashTime)) {
sleep(100);
if(_active) {
waited += 100;
}
}
}
catch(InterruptedException e)
{
} finally {
finish();
startActivity(new Intent(firstactivity.class,secondActivity.class));
stop();
}
}
};
splashTread.start();
}

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
public class Second extends AppCompatActivity {
TextView t1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
t1 = (TextView)findViewById(R.id.textView);
Bundle b = getIntent().getExtras();
String S = b.getString("key1");
t1.setText(S);
try {
wait(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Intent i2 = new Intent();
i2.putExtra("reply","Everything is cool");
setResult(RESULT_OK,i2);
finish();
}
}
This is my second Activity code. Actually, I was seeing how intent works by implementing a very basic program. Program is working without wait, but the app is crashing if I put wait function. provide me some way so that i can stay on to the second activity for a longer time before sending back the r
Use Handler and try to start Intent from run() You can check below example,
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
Intent i2 = new Intent();
i2.putExtra("reply","Everything is cool");
setResult(RESULT_OK,i2);
finish();
}
}, 3000);
you can use service or acyncTask instead of
try {
wait(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
You could try this code
public void onclick(View v) {
mt = new MyTask();
mt.execute();
}
class MyTask extends AsyncTask<Void, Void, Void> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected Void doInBackground(Void... params) {
try {
TimeUnit.SECONDS.sleep(2);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
}
}
Hope it will be helpful.
My splash screen gets error and it is going to force close the app. in Logcat is says Permission Denied. What should i do to fix this problem. Can anyone help me with that matter, Thanks a lot
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.MotionEvent;
public class SplashScreen extends Activity {
protected boolean _active = true;
protected int _splashTime = 4000;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
// thread for displaying the SplashScreen
Thread splashTread = new Thread() {
#Override
public void run() {
try {
int waited = 0;
while(_active && (waited < _splashTime)) {
sleep(100);
if(_active) {
waited += 100;
}
}
} catch(InterruptedException e) {
// do nothing
} finally {
finish();
startActivity(new Intent("com.droidnova.android.splashscreen.BodyPartsGameActivity"));
stop();
}
}
};
splashTread.start();
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
_active = false;
}
return true;
}
}
do this it will easier to you:
private ImageView img;
private Thread t;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img = (ImageView)findViewById(R.id.im1);
t = new Thread(){
#Override
public void run() {
try {
synchronized(this){
wait(2000);
}
// Here your code of animation
}
catch(InterruptedException ex){
ex.printStackTrace();
}
Intent i = new Intent(QuizActivity.this,main.class);
startActivity(i);
}
};
t.start();
}
Your Problem is that you don't add the QuizActivity to the AndroidMainfest.xml
<activity android:name="QuizActivity" ></activity>
than your problem should be solved.
and befor you start the new Activity in splash make
finish();
than you cant go back with back key to it =)
Can you try this once..
Thread splashTread = new Thread() {
#Override
public void run() {
try {
int waited = 0;
while(_active && (waited < _splashTime)) {
sleep(100);
if(_active) {
waited += 100;
}
}
} catch(InterruptedException e) {
// do nothing
} finally {
runOnUiThread(new Runnable() {
#Override
public void run() {
finish();
startActivity(new Intent("com.droidnova.android.splashscreen.BodyPartsGameActivity"));
stop();
}
});
}
}
};
At first my splash screen works perfectly, however later I tried to put in a code which would destroy the activity splash. I did this by putting the onPause method into the end of the protected void.
This is the splash screen before putting in the method
'package com.shipment.emulatorfix;
'import android.app.Activity;
'import android.content.Intent;
'import android.media.MediaPlayer;
'import android.os.Bundle;
'public class Splash extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
} catch(InterruptedException e){
e.printStackTrace();
}finally{
Intent openMain = new Intent("android.intent.action.TESTINGEMULATORACTIVITY");
startActivity(openMain);
}
}
};
timer.start();
}
'}
this is the after code
'package com.shipment.emulatorfix;
'import android.app.Activity;
'import android.content.Intent;
'import android.media.MediaPlayer;
'import android.os.Bundle;
'public class Splash extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
} catch(InterruptedException e){
e.printStackTrace();
}finally{
Intent openMain = new Intent("android.intent.action.TESTINGEMULATORACTIVITY");
startActivity(openMain);
}
}
};
timer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
'}
Any help would be greatly appreciated, thank you.
try this
public class SplashScreen extends Activity {
protected int _splashTime = 2000;
private Thread splashTread;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
splashTread = new Thread() {
#Override
public void run() {
try {
synchronized(this) {
wait(_splashTime);
}
} catch(InterruptedException e) {
System.out.println("EXc=" + e);
}
finally {
startActivity(new Intent(SplashScreen.this, Login.class ));
//stop();
finish();
}
}
};
splashTread.start();
}
}
public class Welcome extends Activity
{
/** Called when the activity is first created. */
Handler mHandler,actHandler;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.welcome);
new Thread(){
public void run(){
try{
Thread.sleep(3000);
}
catch(Exception ex){
Log.e("Welcome Exception :",ex.toString());
}
try{
Message msg=mHandler.obtainMessage();
mHandler.sendMessage(msg);
}
catch(NullPointerException ex){
Log.e("Handler Exception :",ex.toString());
}
}
}.start();
mHandler=new Handler(){
public void handleMessage(Message msg){
super.handleMessage(msg);
Intent i=new Intent(Welcome.this,M_chat.class);
startActivity(i);
finish();
}
};
}
}
Finish the activity and then start the other activity.
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
} catch(InterruptedException e){
e.printStackTrace();
}finally{
finish();
Intent openMain = new Intent("android.intent.action.TESTINGEMULATORACTIVITY");
startActivity(openMain);
}
}
};
This should work for you.
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread timer = new Thread() {
public void run() {
try {
sleep(5000);
} catch(InterruptedException e){
e.printStackTrace();
} finally {
Intent openMain = new Intent("android.intent.action.TESTINGEMULATORACTIVITY");
startActivity(openMain);
Splash.this.finish();
}
}
};
timer.start();
}
I would like to implement a SplashScreen in my app. I found the best and easiest way is to launch an activity that shows a layout with an image view at the launch of the app and then adding android:noHistory="true" attribute to the manifest.
Now, how do I set the splashscreen activity to launch the MainActivity class after a certain amount of time? Lets say 2 seconds?
This is my splashscreen activity
public class SplashActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
}
}
use
handler.postDelayed(runnable, delayinmilliseconds(2000 in your case));
final Runnable runnable = new Runnable()
{
public void run()
{
//start the new activity here.
}
};
Here is a complete sample.
package com.test.splash;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.ImageView;
public class splash extends Activity {
private static final int STOPSPLASH = 0;
//time in milliseconds
private static final long SPLASHTIME = 3000;a
private ImageView splash;
//handler for splash screen
private Handler splashHandler = new Handler() {
/* (non-Javadoc)
* #see android.os.Handler#handleMessage(android.os.Message)
*/
#Override
public void handleMessage(Message msg) {
switch (msg.what) {
case STOPSPLASH:
//remove SplashScreen from view
splash.setVisibility(View.GONE);
break;
}
super.handleMessage(msg);
}
};
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
splash = (ImageView) findViewById(R.id.splashscreen);
Message msg = new Message();
msg.what = STOPSPLASH;
splashHandler.sendMessageDelayed(msg, SPLASHTIME);
}
}
public class TrackMyMoneyActivity extends Activity {
//member fields
private ProgressBar pbar = null;
private TextView counter_txt = null;
Thread splash_thread = null;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
pbar = (ProgressBar) findViewById(R.id.splashpbar);
counter_txt = (TextView) findViewById(R.id.countertxt);
//define thread
splash_thread = new Thread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
int i = 0;
for( i=0;i<100;i++){
pbar.setProgress(i);
// counter_txt.setText(i+" %");
try {
splash_thread.sleep(100);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(i==100){
Intent intent = new Intent(getBaseContext(), LoginApp.class);
startActivity(intent);
}
}
});
splash_thread.start();
}
#Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
}
}
I hope it will be solved your solution.
You can also use java.util.Timer in this way:
new Timer().schedule(new TimerTask(){
public void run() {
startActivity(new Intent(SplashActivity.this, MainActivity.class));
}
}, 2000 /*amount of time in milliseconds before execution*/ );
public class Splashscreen extends Activity
{
private static final int SPLASH_TIME = 10 * 1000;// 3 seconds
Button logo;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// requestWindowFeature(Window.FEATURE_NO_TITLE);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.splashscreen);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
try {
new Handler().postDelayed(new Runnable() {
public void run() {
Intent intent = new Intent(Splashscreen.this,MainActivity.class);
startActivity(intent);
Splashscreen.this.finish();
//overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
}
}, SPLASH_TIME);
new Handler().postDelayed(new Runnable() {
public void run() {
}
}, SPLASH_TIME);
} catch(Exception e){}
// METHOD 1
/****** Create Thread that will sleep for 5 seconds *************/
Thread background = new Thread() {
public void run() {
try {
// Thread will sleep for 5 seconds
sleep(50*1000);
// After 5 seconds redirect to another intent
Intent i=new Intent(getBaseContext(),MainActivity.class);
startActivity(i);
//Remove activity
finish();
} catch (Exception e) {
}
}
};
background.start();
}
I have a problem that I want to paste images on ImageView in Android and that images are periodically changed after some interval. Means one by one images shown in ImageView. I am doing this with the help of Thread in java but I got some problem that Thread is not attached and something. Please review my code given below and tell me the exact error and how to remove that error or give me some diffrent way for doing this.
package com.ex.thread;
import com.ex.thread.R;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ImageView;
public class thread extends Activity implements Runnable{
/** Called when the activity is first created. */
public static Integer[] mThumbIds = {
R.drawable.al1,R.drawable.al2,R.drawable.al3,R.drawable.al4,
};
Thread th;
ImageView iv;
public void run()
{
for(int i=0;i<3;i++)
{
iv.setImageResource(mThumbIds[i]);
System.out.println("Sanat Pandey");
try{
Thread.sleep(3000);
}catch(Exception e)
{
System.out.println(e);
}
}
}
public void create()
{
Thread th = new Thread(new thread());
th.start();
try{
Thread.sleep(3000);
}catch(Exception e)
{
System.out.println(e);
}
}
#Override
public void onCreate(Bundle savedInstace)
{
super.onCreate(savedInstace);
setContentView(R.layout.main);
create();
}
}
Try this..It works out well...
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);``
//
//
int []imageArray={R.drawable.img1,R.drawable.img2,R.drawable.img3};
final Handler handler = new Handler();
Runnable runnable = new Runnable() {
int i=0;
public void run() {
imageView.setImageResource(imageArray[i]);
i++;
if(i>imageArray.length-1)
{
i=0;
}
handler.postDelayed(this, 50); //for interval...
}
};
handler.postDelayed(runnable, 2000); //for initial delay..
}
You can't use things in the UI thread from a background one. So this call:
iv.setImageResource(mThumbIds[i]);
Has to be done in the main thread. In fact you probably don't need a background thread at all to get the effect you're looking for. You can make that just an activity, no need to implement runnable. and then do something like this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
iv = (ImageView) findViewById(R.id.yourImageViewID);
int i = 0;
Runnable r = Runnable(){
public void run(){
iv.setImageResource(mThumbIds[i]);
i++;
if(i >= mThumbIds.length){
i = 0;
}
iv.postDelayed(r, 3000); //set to go off again in 3 seconds.
}
};
iv.postDelayed(r,3000); // set first time for 3 seconds
Try this
it's working
public class vv extends Activity {
int b[] = {R.drawable.a, R.drawable.m, R.drawable.b, R.drawable.j, R.drawable.er, R.drawable.chan, R.drawable.vv};
public ImageView i;
int z = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
i = (ImageView) findViewById(R.id.image);
i.setImageResource(b[0]);
Thread timer = new Thread() {
public void run() {
try {
sleep(2000);
for (z = 0; z < b.length + 2; z++) {
if (z < b.length) {
sleep(2000);
runOnUiThread(new Runnable() {
public void run() {
i.setImageResource(b[z]);
}
});
} else {
z = 0;
}
}
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
System.out.println("finally");
}
}
};
timer.start();
}
}
