Android: Updating a Textview for an activity inside a thread

Android: Updating a Textview for an activity inside a thread - android

Working with two activities. If I wanted to do something like checking internet connectivity and updating another activity with the result, how do I get the statusMessage to display on the 2nd activity layout in the Textview there when I'm inside a thread of the 1st activity... Right now, the text doesn't change on the 2nd activity's textview. If I need to reference a property from the 2nd activity from the first launch one, how do I do that?
Second Activity:
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.TextView;
public class CopyOfSplash extends Activity {
protected boolean _active = true;
protected int _splashTime = 15000;
TextView mainText;
String statusMessage;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread splashTread = new Thread() {
#Override
public void run() {
try {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if (netInfo.isConnected())
{
statusMessage= "Connected to the internet!";
}
else
{
statusMessage = "User is probably in airplane mode!";
}
} catch(InterruptedException e) {
// do nothing
} finally {
finish();
startActivity(new Intent("com.nwp.Main"));
runOnUiThread(new Runnable() {
#Override
public void run() {
setContentView(R.layout.main);
mainText = (TextView) findViewById(R.id.mainTextView);
mainText.setText(statusMessage);
}
});
stop();
}
}
};
splashTread.start();
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
_active = false;
}
return true;
}
}
First Activity:
public class Main extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
Manifest File:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</activity>
</application>

Why don't you just move the TextView changing code inside your second activity's onCreate method? In order to call findViewById() you need your TextView's parent layout set as a content view of the current showing activity, otherwise findViewById() will return null.

onClickListener crashes program wont link to another activity android

My Main Activity class is as follows
package com.example.barnight2;
import java.text.SimpleDateFormat;
import java.util.Date;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView date;
private Button taxiButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton();
dateAndTime();
}
public void addListenerOnButton() {
taxiButton = (Button) findViewById(R.id.btnTaxi);
taxiButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent taxiIntent = new Intent(MainActivity.this, TaxiActivity.class);
startActivity(taxiIntent);
}
});
}
public void dateAndTime() {
date = (TextView) findViewById(R.id.lblDate);
SimpleDateFormat sdf = new SimpleDateFormat("EEEE");
Date day = new Date();
String dayOfTheWeek = sdf.format(day);
date.setText(dayOfTheWeek);
}
}
then i have my second activity called the Taxi Activity
package com.example.barnight2;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class TaxiActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_taxi);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.taxi, menu);
return true;
}
}
Here is my Manifest.xml i thought i had done everything perfectly but it seems to always crash upon start up of the app
<?xml version="1.0" encoding="utf-8"?>

ClassCastException
you're casting an object that it's not the same type you're trying to cast, so that's why it throw a RunTimeException with ClassCastException.
It should be:
taxiButton = (ImageButton) findViewById(R.id.btnTaxi);
Since you declared it as ImageButton in xml.

Please remove :
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
from your activity com.example.barnight2.TaxiActivity in the AndroidManifest.xml

import android.app.Activity;

import android.view.View;
import android.widget.Button;
public class Register extends Activity implements View.OnClickListener {
Button backlog,regg;
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
backlog = (Button) findViewById(R.id.loginn);
regg = (Button) findViewById(R.id.signup);
backlog.setOnClickListener(this);
}
public void onClick (View v)
{
switch(v.getId()) {
case R.id.loginn:
break;
case R.id.signup:
Intent in = new Intent();
in.setClass(Register.this,MainActivity.class);
startActivity(in);
break;
}
}
}

Firstly
Change where you intent with this:
Intent intent = new Intent(Home.this,MainActivity.class);
startActivity(intent);
Secondly
Just update your manifest with this:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.droid.mine.Home"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.droid.mine.MainActivity"
android:label="#string/app_name" >
</activity>
<activity
android:name="com.droid.mine.Register"
android:label="#string/app_name" >
</activity>
</application>
Use this as home activity
package com.example.pms;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.MotionEvent;
import android.widget.Toast;
public class SplashScreen extends Activity {
/*
* The thread to process splash screen events
*/
private Thread mSplashThread;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// splash screen view
setContentView(R.layout.activity_splash);
final SplashScreen mSplashScreen=this;
/*
* The thread to wait for splash screen events
*/
mSplashThread =new Thread(){
#Override
public void run(){
try {
synchronized(this){
// Wait given period of time or exit on touch
wait(3000);
}
}
catch(InterruptedException ex){
}
finish();
// Run next activity
startActivity(new Intent(getBaseContext(), MainActivity.class));
new Runnable() {
#Override
public void run() {
mSplashThread.stop();
}
};
}
};
mSplashThread.start();
}
/**
* Processes splash screen touch events
*/
#Override
public boolean onTouchEvent(MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN)
{
synchronized(mSplashThread){
mSplashThread.notifyAll();
}
}
return true;
}
}

you can use this code instead
replace
.MainActivity
with
com.droid.mine.MainActivity
while declaring in Manifest file.
//delay in ms
int DELAY = 1000;
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(Home.this,MainActivity.class);
startActivity(intent);
}
}, DELAY);

Change your Intent to:
Intent openMainActivity = new Intent(Home.this, MainActivity.class);
startActivity(openMainActivity);
and in manifest file use:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.testapp.Home"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
</activity>
</application>
</manifest>

You need to register MainActivity and Register Activity in the manifest:
<activity android:name=".Mainactivity" />
<activity android:name=".Register" />
log.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
});
}
sign.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Intent i = new Intent();
i.setClass(MainActivity.this,Register.class);
startActivity(i);
});
}

I hope this works:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class Home extends Activity{
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
Thread splashTimer = new Thread() {
public void run() {
try {
int splashTimer = 0;
while (splashTimer < 2000) {
sleep(100);
splashTimer = splashTimer + 100;
}
Intent intent;
intent = new Intent(Home.this, MainActivity.class);
startActivity(intent);
finish();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
Log.d("asd","dasd");
}
finally {
finish();
}
}
};
splashTimer.start();
}
}
Edit: Replace your manifest file with this, now I hope it works:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.droid.mine"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.droid.mine.Home"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.droid.mine.MainActivity"
android:label="#string/app_name" >
</activity>
</application>
</manifest>

Splash and main activity error

Can someone please help. After the splash activity, the main activity isn't opening up. But if I put in any other intent filter name it works Just not the main activity. Thanks in advance!

Try this in your Splash Activity..
Intent yo = new Intent (Splash.this, MainActivity.class);
startActivity(yo);
In your manifest file
<activity
android:name="com.hellhog.tfreqpro.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action2.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
delete the following lines of intent filtter
<intent-filter>
<action android:name="android.intent.action2.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Here is what working for me perfectly !
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE); // Removes title bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // Removes notification bar
setContentView(R.layout.splashscreen);
// Start timer and launch main activity
IntentLauncher launcher = new IntentLauncher();
launcher.start();
}
private class IntentLauncher extends Thread {
#Override
/**
* Sleep for some time and than start new activity.
*/
public void run() {
try {
// Sleeping
Thread.sleep(SLEEP_TIME*1000);
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
// Start main activity
Intent intent = new Intent(SplashActivity.this,FullscreenActivity.class);
SplashActivity.this.startActivity(intent);
SplashActivity.this.finish();
}
}

Try to use below code..
public class SplashScreenextends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
// TODO Auto-generated method stub
finish();
Intent menu = new Intent(getBaseContext(), MainActivity.class);
startActivity(menu);
}
}, 3000);
}
}
It will set your SplashScreen for 3 seconds and then starts your mainactivity or whatever activity you want to start.MAy it helps you..

android.content.ActivityNotFoundException: No Activity found to handle Intent splash screen

I am having an issue with loading up a new intent after my splash screen. I have looked at questions relating to this exception but they all seem to be dealing with thing like google play or google maps not being referenced correctly this is not the case for me.
These are the related questions I have looked at

super.onPause();
finish();
}
}
And here is the class HomePage I am trying to load after the splash screen
package com.android.main;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.Spinner;
import android.widget.TextView;
public class HomePage extends Activity {
/** Called when the activity is first created. */
TextView name;
EditText editName;
TextView drinks;
Spinner drinksSpinner;
TextView message;
CheckBox checkbox;
Button createOrderButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
createOrder();
}
public void createOrder(){
createOrderButton = (Button) findViewById(R.id.bCreateOrder);
createOrderButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
postInformationtoAPI();
}
private void postInformationtoAPI() {
goToOrderCompleted();
}
private void goToOrderCompleted() {
Intent intent = new Intent(HomePage.this , OrderPlaced.class);
HomePage.this.startActivity(intent);
Log.i("onClick", "trying to start new activity to change layout");
}
});
}
}
The app force quits after loading the splash screen and gives the following exception
03-14 22:32:33.553: E/AndroidRuntime(3166): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.android.main.HOMEPAGE }
Any help with this would be greatly appreciated

You have to differentiate the Intent's Constructor,
Intent openStartingPoint = new Intent("com.android.main.HOMEPAGE");
Which assume com.android.main.HOMEPAGE as Intent's action Filter. Which is not available in your application's android manifest.xml file. You have
<action android:name="android.intent.action.HOMEPAGE" />
which should be,
<action android:name="com.android.main.HOMEPAGE" />
OR just change it with,
Intent openStartingPoint = new Intent(Splash.this, HOMEPAGE.class);

<activity
android:label="#string/app_name"
android:name=".SplashScreen"
android:screenOrientation="landscape"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.android.main.HOMEPAGE"
android:screenOrientation="landscape"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen" >
<intent-filter >
<action android:name="com.android.main.HOMEPAGE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Also i would have a timer task to display splash screen
public class SplashScreen extends Activity{
Timer splashTimer;
SplashTimerHandler splashTimerHandler;
private boolean applicationPaused=false;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
this.setSplash();
}
private void setSplash()
{
this.splashTimerHandler=new SplashTimerHandler();
this.splashTimer=new Timer();
this.splashTimer.schedule(this.splashTimerHandler, 0, 1000);
}
#Override
public void onPause()
{
super.onPause();
this.applicationPaused=true;
this.closeSplashTimer();
}
#Override
public void onResume()
{
super.onResume();
if(this.applicationPaused)
{
this.applicationPaused=false;
this.closeSplashTimer();
this.setSplash();
}
}
public class SplashTimerHandler extends TimerTask{
int splashTimerCounter=0;
#Override
public void run()
{
splashTimerCounter++;
if(splashTimerCounter>2)
{
runOnUiThread(splashTimeOver);
}
}
private Runnable splashTimeOver=new Runnable() {
#Override
public void run()
{
closeSplashTimer();
startHomeScreen();
}
};
}
protected void closeSplashTimer()
{
if(this.splashTimer!=null)
{
this.splashTimer.cancel();
this.splashTimer=null;
}
}
private void startHomeScreen()
{
this.closeSplashScreen();
startActivity(new Intent("com.android.main.HOMEPAGE"));
}
private void closeSplashScreen()
{
this.closeSplashTimer();
this.finish();
}
#Override
public boolean onKeyDown(int keycode, KeyEvent event)
{
if(keycode==KeyEvent.KEYCODE_BACK)
{
this.closeSplashScreen();
}
return true;
}
}

Using two or more activty on Android

code below, don't know whats the problem
package and.views;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class androidView extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public boolean onCreateOptionsMenu(Menu menu)
{
super.onCreateOptionsMenu(menu);
menu.add(0,0, 0, "AutoComplete");

Chetan, I'm not quite sure what the exact problem you are having here, but I'm guessing you get a nullPointerException when you try to launch a new Activity? I didn't take an extensive look at your code but I noticed you don't have any of the extra Activities in your Manifest. Anytime you create a new Activity to be launched you need to add it to the Manifest. I'm pretty new to Android so I'm not too sure why all this is, but I came across that problem before as well.

Not too sure if the answer came too late for you.
Not much information about simple_list_item_1 online I can find, but if your problem is with the AutoCompleteTextView context popup not showing any of your prefilled autocomplete text, a change to simple_dropdown_item_1line should solve the problem
Note: I'm testing on API8

Why don't you just move the TextView changing code inside your second activity's onCreate method? In order to call findViewById() you need your TextView's parent layout set as a content view of the current showing activity, otherwise findViewById() will return null.
