Android media player progress bar rest to "0" when stop music

I put one song into an app (tabhost) and I have progress bar, play button, stop button, loop button.
The function I want is:
when user plays the music, the progress bar starts to run from "0"
when user presses stop, the progress bar stops at where it was, waits for the user to press play again, and then continues where it left off
I might change the button name to "pause" later, but this is the function I need right now.
Right now, 2 issues:
When stop is pressed, the progress bar returns to "0", but the music resumes playing from where it left off (music not playing from very beginning)
The progress bar runs faster than desired; it runs to the end before the music ending.
Here is my code, hope someone could help thank you so much:

Android: launch progressbar in start of application

I have the code bellow when I click button it display a progress bar dialog.
public class MyAndroidAppActivity extends Activity {

}
}
But I want to display it(progress bar dialog) in start of my android application.
How can I do this ? Thanks in advance for any help.

Progress bar onclick button in android?

How to bring a progress bar on clicking a button in an activity i have an button in my main activity and if i click the button i want to display a progress bar i dont wanna use a secondary activity for this i have done with 2 activities but i need it to be done in main activity itself.
thank you
My code:
Home Activity :
public void load(View v){
Intent intent = new Intent(this,Splash.class);
this.startActivity(intent);
}
Splash Activity :
public class Splash extends Activity {
private long ms = 0;
private long splashTime = 20000;
private boolean splashActive = true;
private boolean paused = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread mythread = new Thread() {
public void run() {
try {
while (splashActive && ms < splashTime) {
if (!paused)
ms = ms + 100;
sleep(100);
}
} catch (Exception e) {
} finally {
Intent intent = new Intent(Splash.this, Home.class);
startActivity(intent);
}
}
};
mythread.start();
}
}

You can do like this
ProgressDialog progress;
progress = new ProgressDialog(this);
progress.setTitle("Please Wait!!");
progress.setMessage("Wait!!");
progress.setCancelable(true);
progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progress.show();
call this code where you want to display your ProgressBar.

There is one more method to show the ProgressBar on Button Click.
Put this code in your xml
<ProgressBar
android:id="#+id/progressBar1"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="invisible" />
and just write following code on your Button click in java file.
progressBar.setVisibility(View.VISIBLE);
It will show the Progressbar on your Button Click.

I believe the user2306156 will not be in need of this now, hopefully someone who is looking for this will be glad to know i guess.
put this code in your xml
<ProgressBar
style="#android:style/Widget.Material.Light.ProgressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/checkBox"
android:layout_centerHorizontal="true"
android:layout_marginTop="57dp"
android:id="#+id/progressBar" />
put this in your activity code
spinner=(ProgressBar)findViewById(R.id.progressBar);
spinner.setVisibility(View.GONE);
and this in your onClick of the activity code
spinner.setVisibility(View.VISIBLE);

See this Android Progress Bar Example
public class MyAndroidAppActivity extends Activity {
Button btnStartProgress;
ProgressDialog progressBar;
private int progressBarStatus = 0;
private Handler progressBarHandler = new Handler();
private long fileSize = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
addListenerOnButton();
}
public void addListenerOnButton() {
btnStartProgress = (Button) findViewById(R.id.btnStartProgress);
btnStartProgress.setOnClickListener(
new OnClickListener() {
#Override
public void onClick(View v) {
// prepare for a progress bar dialog
progressBar = new ProgressDialog(v.getContext());
progressBar.setCancelable(true);
progressBar.setMessage("In Progress ...");
progressBar.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressBar.setProgress(0);
progressBar.setMax(100);
progressBar.show();
//reset progress bar status
progressBarStatus = 0;
//reset filesize
fileSize = 0;
new Thread(new Runnable() {
public void run() {
while (progressBarStatus < 100) {
// process some tasks
progressBarStatus = doSomeTasks();
// your computer is too fast, sleep 1 second
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
// Update the progress bar
progressBarHandler.post(new Runnable() {
public void run() {
progressBar.setProgress(progressBarStatus);
}
});
}
// ok, file is downloaded,
if (progressBarStatus >= 100) {
// sleep 2 seconds, so that you can see the 100%
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
// close the progress bar dialog
progressBar.dismiss();
}
}
}).start();
}
});
}
// file download simulator... a really simple
public int doSomeTasks() {
while (fileSize <= 1000000) {
fileSize++;
if (fileSize == 100000) {
return 10;
} else if (fileSize == 200000) {
return 20;
} else if (fileSize == 300000) {
return 30;
}
// ...add your own
}
return 100;
}
}

Another Option is to use the nifty Spezi-Views, it contains a ProgressButton which is quite easy to use:
<de.halfreal.spezi.views.ProgressButton
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Press me"
app:selectedText="I am loaded"
app:unselectedText="Press me again"
app:loadingDrawable="#drawable/spinner"
/>
and in code:
...
//show a rotation spinner, and no text (or the loading text)
progressButton.enableLoadingState();
//show no animation, but the selected/ unselected text
progressButton.disableLoadingState();
...

displaying progressbar using threading

I am trying to display a progress bar using threading .. I accept that I do not have that much concept of threading.
Here is the code
public class Progress extends Activity {
static String[] display;
private static final int Progress = 0;
private ProgressBar mProgress;
private int mProgressStatus = 0;
private Handler mHandler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.progress);
mProgress = (ProgressBar) findViewById(R.id.progressBar);
// Start lengthy operation in a background thread
new Thread(new Runnable() {
public void run() {
while (mProgressStatus < 100) {
mProgressStatus = doWork();
// Update the progress bar
mHandler.post(new Runnable() {
public void run() {
mProgress.setProgress(mProgressStatus);
}
});
}
}
private int doWork() {
display = new Logic().finaldata();
// TODO Auto-generated method stub
return 100;
}
}).start();
}
}
On running, the logcat message is
java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
What is the mistake that I am doing here?

So your problem will be elsewhere. I tried your example with Handler and it works for me.
package com.sajmon.threadsDemo;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.widget.ProgressBar;
import android.widget.TextView;
public class ThreadsDemoActivity extends Activity {
ProgressBar bar;
TextView label;
Handler handler = new Handler();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
bar = (ProgressBar) findViewById(R.id.progBar);
new Thread(new Runnable() {
int i = 0;
int progressStatus = 0;
public void run() {
while (progressStatus < 100) {
progressStatus += doWork();
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
// Update the progress bar
handler.post(new Runnable() {
public void run() {
bar.setProgress(progressStatus);
i++;
}
});
}
}
private int doWork() {
return i * 3;
}
}).start();
}
}
And XML:
<ProgressBar
android:id="#+id/progBar" style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
So look at this and edit your code similar with this.

Find the below example code for progress bar update using threads
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.ProgressBar;
import android.widget.TextView;
public class ThreadDemo1ProgressBar extends Activity
{
ProgressBar bar;
TextView msgWorking;
boolean isRunning = false;
Handler handler = new Handler(){
#Override
public void handleMessage(Message msg) {
bar.incrementProgressBy(5);
if (bar.getProgress() == bar.getMax()) {
msgWorking.setText("Done");
bar.setVisibility(View.INVISIBLE);
} else {
msgWorking.setText("Working..." +
bar.getProgress());
}
}// handleMessage
};
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
bar = (ProgressBar) findViewById(R.id.progress);
bar.setMax(100);
msgWorking = (TextView) findViewById(R.id.TextView01);
}
public void onStart() {
super.onStart();
bar.setProgress(0);
Thread background = new Thread(new Runnable() {
public void run() {
try
{
for (int i = 0; i < 20 && isRunning; i++) {
Thread.sleep(1000);
handler.sendMessage(handler.obtainMessage());
}
}
catch(Throwable t) {
// just end the background thread
}
}
});
isRunning = true;
background.start();
}// onStart
public void onStop() {
super.onStop();
isRunning = false;
}
}// ThreadDemo1ProgressBar
The about example updating the progress bar for every 5 seconds.

I actually just create a thread instance once and it works anyway. This code was written in the Startup Activity. All you need to do is call showSpinner1() method to show/hide the spinner.
Ensure to do this
getWindow().requestFeature(Window.FEATURE_INDETERMINATE_PROGRESS); in your onCreate() method and use this code for toggling the spinner ON and OFF.
// Spinner related code - The thread is created just once and is used multiple times (works!!)
boolean toShow = false;
Thread spinner1Thread = new Thread("Show/Hide Spinner Thread") {
#Override
public void run() {
setProgressBarIndeterminateVisibility(toShow);
}
};
/**
* Shows and hides the spinner
* #param pShow
*/
public void showSpinner1(boolean pShow) {
toShow = pShow;
runOnUiThread(spinner1Thread);
}

progressbar doesn't show on screen

I need to show a second activity after the progress bar is filled. I tried the code below but it doesn't show the progress bar and just shows my second activity.
This is the code:
public class MiSuper2 extends Activity {
String strListas[] = null;
private ProgressBar mProgress;
private int mProgressStatus = 0;
private Handler mHandler = new Handler();
private StoreData stdArticulos = null;
public Cursor cursor = null;
private long fileSize = 0;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
stdArticulos = new StoreData(this);
fileSize = 0;
setContentView(R.layout.main);
stdArticulos = new StoreData(this);
cursor = stdArticulos.leerArticulos();
mProgress = (ProgressBar) findViewById(R.id.progressbar_activity);
new Thread(new Runnable() {
public void run() {
while (mProgressStatus < 100) {
mProgressStatus = doWork();
mHandler.post(new Runnable() {
public void run() {
mProgress.setProgress(mProgressStatus);
}
});
}
}
}).start();
if(cursor.moveToFirst()) {
do{
strListas[cursor.getPosition()] = cursor.getString(cursor.getPosition());
}while(cursor.moveToNext());
}
Intent intent = new Intent(MiSuper2.this, PntArticulo.class);
startActivity(intent);
}
public int doWork() {
while (fileSize <= 1000000) {
fileSize++;
return (int) fileSize;
}
return 100;
}
}
This is the main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

style="?android:attr/progressBarStyleHorizontal"
android:layout_width="200dp"
android:layout_height="wrap_content" android:layout_marginTop="100dp"/>
</LinearLayout>
Please help

It looks like you are using the doWork() function to take up time so that you're progress bar does something. Even though you wrote a big loop, it still executes very quickly so you don't see your progress bar move. Rather, you want to simulate your Thread doing something computationally intensive by using Thread.sleep() which takes an argument that is the time to sleep in milliseconds.
Try changing your code to this:
new Thread(new Runnable() {
public void run() {
while (mProgressStatus < 100) {
try {
mProgressStatus += doWork();
} catch (InterruptedException e) {
e.printStackTrace();
}
mHandler.post(new Runnable() {
public void run() {
mProgress.setProgress(mProgressStatus);
}
});
}
runOnUiThread(new Runnable() {
#Override
public void run() {
startActivity(new Intent(MiSuper2.this, Second.class));
}
});
}
}).start();
And...
public int doWork() throws InterruptedException {
Thread.sleep(1000);
return 1;
}
This will increment your progress bar by 1% every second. And finally, the documentation on Thread.sleep(): https://developer.android.com/reference/java/lang/Thread.html#sleep(long)
EDIT: Ramz beat me to this answer, but doesn't provide an explanation of why it's the answer. Hopefully my explanation helps.
EDIT2: I think you edited your questions since I started looking at it a second time. You had some errors in your XML before, but now it is gone. Regardless, your problem is now that you need the call to startActivity() inside your worker thread. Otherwise, the UI thread does not wait for the doWork() function to return and immediately starts the other Activity when your app starts. Sorry, I should have mentioned this before. The code I posted above is updated with this change.
