How to automate Seekbar movement with a song in Android?

I know similar questions have been asked before but none of them could solve my problem. I'm making a music player and wish to automate the Seekbarwhen a song is played. I'm using a RecyclerViewand the following snippet exists in the onBindViewHolder section.
public class ListViewPopulator extends
RecyclerView.Adapter<ListViewPopulator.ViewHolder>{
List<String> musicName;
List<String> musicAdd;
Context context;
MediaPlayer mediaPlayer;
Button media_play;
Button media_stop;
SeekBar seekBar;
final Handler mhandler=new Handler();
TextView timer;
public ListViewPopulator(Activity context, List<String> musicName, List<String> musicAdd)
{
this.context=context;
this.musicName=musicName;
this.musicAdd=musicAdd;
media_play= (Button)context.findViewById(R.id.play);
media_stop=(Button)context.findViewById(R.id.pause);
seekBar= (SeekBar) context.findViewById(R.id.seekbar);
timer=(TextView) context.findViewById(R.id.timer);
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(R.layout.listview,parent,false);
return new ViewHolder(v);
}
void something(String s)
{
try{mediaPlayer.stop();}catch (NullPointerException e){e.printStackTrace();}
//To fetch the location of audio files on disk
mediaPlayer=MediaPlayer.create(context, Uri.fromFile(new File(s)));
mediaPlayer.start();
//seekBar.setProgress(0);
//seekBar.setMax(mediaPlayer.getDuration());
} int temp=0;
int i=0;
#Override
public void onBindViewHolder(ViewHolder holder, final int position) {
final String s = musicAdd.get(position);
final String v = musicName.get(position);
holder.data.setText(v);
seeker();
cont_seek();
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
temp = position + 1;
something(s);
seekBar.setProgress(0);
seekBar.setMax(mediaPlayer.getDuration());
// mediaPlayer.reset();
change();
op();
}
});
media_play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
mediaPlayer.start();
Log.d("click", "Kuch bhi");
} catch (NullPointerException e) {
e.printStackTrace();
}
}
});
media_stop.setOnClickListener(new View.OnClickListener() {
#Override

} catch (NullPointerException e) {

}

int progress = mediaPlayer.getCurrentPosition();
int min = (progress / 1000) / 60;

int sec = (progress / 1000) % 60;
if (sec < 10)
time = "0" + sec;
else
time = "" + sec;
String elapsedTime = min + ":" + time + "";
timer.setText(elapsedTime);
seekBar.setMax(mediaPlayer.getDuration());
seekBar.setProgress(progress);
mhandler.postDelayed(this, 1000);
}
}
};
mhandler.postDelayed(runnable,1000);
}
void seeker(){
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
int seek_progress;
String time_sec;
#Override
public void onProgressChanged(final SeekBar seekBar, int progress, boolean fromUser) {

}
public class ViewHolder extends RecyclerView.ViewHolder
{
TextView data;
public ViewHolder(View itemView) {
super(itemView);
data=(TextView)itemView.findViewById(R.id.data);
}
}
}
I am pretty sure the logic is right and have checked the Log, the code doesn't seem to be executing. Can somebody explain why?

In your recycler view adapter you can use something like this:
#Override
public VoiceViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return VoiceViewHolder.createVoiceViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.lecture_voice_item_recycler, parent, false));
}
#Override
public void onBindViewHolder(VoiceViewHolder holder, int position) {
holder.bindHolderToVoice(10000, "your path");
}

boolean isPlaying;

double timeElapsed = 0, finalTime = 0;
Handler durationHandler = new Handler();
Runnable updateSeekBarTime;
SeekBar seekBarDuration;
private VoiceViewHolder(final View itemView) {
super(itemView);
}
public static VoiceViewHolder createVoiceViewHolder(View convertView) {
VoiceViewHolder holder = new VoiceViewHolder(convertView);
holder.voiceDuration = (TextView) convertView.findViewById(R.id.voice_duration);
holder.cardView = (CardView) convertView.findViewById(R.id.card_view);
holder.voiceView = (ImageView) convertView.findViewById(R.id.voiceView);
holder.mPlayButton = (ImageButton) convertView.findViewById(R.id.playButton);
holder.layoutVoice = (RelativeLayout) convertView.findViewById(R.id.layoutVoice);

holder.isPlaying = false;
holder.mPlayer = new MediaPlayer();
return holder;
}
public void bindHolderToVoice(final long duration, final String path) {
final Context context = itemView.getContext();
if (duration >= 60000) {
voiceDuration.setText(String.format("%d %s, %d %s", TimeUnit.MILLISECONDS.toMinutes(duration), context.getString(R.string.min),
TimeUnit.MILLISECONDS.toSeconds(duration) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(duration)),
context.getString(R.string.sec)));
} else {
voiceDuration.setText(String.format("%d %s",
TimeUnit.MILLISECONDS.toSeconds(duration) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(duration)),
context.getString(R.string.sec)));
}
finalTime = duration;
seekBarDuration.setMax((int) finalTime);
seekBarDuration.setClickable(false);
seekBarDuration.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {

voiceDurationPlayer.setText(String.format("%02d:%02d", TimeUnit.MILLISECONDS.toMinutes((long) timeElapsed), TimeUnit.MILLISECONDS.toSeconds((long) timeElapsed) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes((long) timeElapsed))));
durationHandler.postDelayed(this, 100);
} else {
mPlayer.pause();
isPlaying = false;
}
}
}
};
File voiceFile = new File(path);
mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
isPlaying = false;
}
});

} else {

mPlayer.pause();
}
}
});
}
}

Note: some dimensions or drawables could be lost in the example. You should use your own dimension if no compile.

You need to use your Handler & Runnable as follows:
final Handler handler = new Handler();
final Runnable r = new Runnable() {
public void run() {
//YOUR CODE GOES HERE
handler.postDelayed(this, 1000);
}
};
handler.postDelayed(r, 0);

Found a solution for this.
Runnable runnable=new Runnable() {
#Override
public void run() {
String time;
Log.d(TAG, "run");
while(mediaPlayer != null && mediaPlayer.isPlaying()){
final int progress = mediaPlayer.getCurrentPosition();
int min = (progress / 1000) / 60;
Log.d("auto","seek");
int sec = (progress / 1000) % 60;
if (sec < 10)
time = "0" + sec;
else
time = "" + sec;
final String elapsedTime = min + ":" + time + "";
context.runOnUiThread(new Runnable() {
#Override
public void run() {
timer.setText(elapsedTime);
seekBar.setMax(mediaPlayer.getDuration());
seekBar.setProgress(progress);
}
});
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
new Thread(runnable).start();
The main problem here is that once mediaplayer.start() is called the media file begins loading in the player before that completes the cont_seek function is called which has the condition
if(mediaplayer!=null && mediaplayer.isplaying())
Since the media hasn't started playing yet, the condition fails and the function is never executed.
Fixed it by running the runnable in a different thread.

why display black background between two layouts

I have radio app stream, and when open this app, first its open splash layout like this :
splash.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#drawable/loading" />
<ProgressBar
android:id="#+id/progressBar1"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.67" />
</LinearLayout>
and class for it like :
StartPoint.java
public class StartPoint extends Activity{
ProgressBar progressBar;
private int progressBarStatus = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
progressBar = (ProgressBar)findViewById(R.id.progressBar1);
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
while(progressBarStatus < 5000){
StartPoint.this.runOnUiThread(new Runnable(){
public void run()
{
progressBar.setProgress(progressBarStatus);
progressBarStatus += 1000;
}
});
}
}catch(InterruptedException e){
e.printStackTrace();
}finally{
Intent openMainList = new Intent(StartPoint.this,
com.example.kam.MainActivity.class);
startActivity(openMainList);
}
}
};
timer.start();
}
#Override
protected void onStop(){
super.onStop();
finish();
}
}
this class when finished, its call MainActivity.java class, and its show :

why when trans from splash.xml to activity_main.xml display black background few min and display app.

Since you are changing activity, its gonna show some animation or black screen like you said. Its the default behavior. You can use a custom dialog with your splash layout on top of main activity. you can trigger the dialog to close on progress complete. Using two activities can have other effects. for instance when the user hits the back button, its gonna go back to splash screen instead of exiting the app.

try it
Thread timer = new Thread(){
public void run(){
try{
while(progressBarStatus < 5000){
StartPoint.this.runOnUiThread(new Runnable(){
public void run()
{
progressBar.setProgress(progressBarStatus);
progressBarStatus += 1000;
}
});
sleep(5000);
}

text for marquee dynamically

Is it possible to add text from java coding of a list view to marquee scroll in Android. If yes can you please let me know how?
If needed I shall post the code used.
This was the XML for listview used is as follows
<?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="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/linearLayout1"

If you need to move text around, maybe this will help:
http://developer.android.com/guide/topics/resources/animation-resource.html#translate-element
If you have a TextView with a text that is too big and you want it to move around so people can read the whole thing, try android:ellipsize="marquee" in the .xml file, or in the Java code:
textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);

If the android libraries not enough, you can always use the java via coding. Create a thread class that gets the views and change conditions over time. You can create an intent to call that class.

You can use the TextSwitcher and apply the animation on it.
Try below code:
public class TextSwitcherActivity extends Activity implements ViewSwitcher.ViewFactory,
View.OnClickListener
{
private TextSwitcher m_switcher;
private Button m_nextButton;
private int m_counter = 0;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
m_switcher = (TextSwitcher) findViewById(R.id.tsSwitcher);
m_switcher.setFactory(this);
Animation in = AnimationUtils.loadAnimation(this, android.R.anim.fade_in);
Animation out = AnimationUtils.loadAnimation(this, android.R.anim.fade_out);
m_switcher.setInAnimation(in);
m_switcher.setOutAnimation(out);
m_nextButton = (Button) findViewById(R.id.next);
m_nextButton.setOnClickListener(this);
updateCounter();
}
/**
* Update counter value
*/
public void onClick(View v)
{
m_counter++;
updateCounter();
}
/**
* Set text on textswitcher
*/
private void updateCounter()
{
m_switcher.setText(String.valueOf(m_counter));
}
public View makeView()
{
TextView t = new TextView(this);
t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
t.setTextSize(36);
return t;
}
You can define your own animations to get the marquee effect.

Here is the example
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/mywidget"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:lines="1"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:textColor="#ff4500"
android:text="Simple application that shows how to use marquee, with a long text" />
In java (If you are using a Listview and binding an adapter, then in getview when u inflate Layout and its view component, set the selected flag to true to your TextView.)
tv = (TextView) this.findViewById(R.id.tv);
tv.setSelected(true);

By using below method you can convert your list of string values into a single string,
String listString = String.join(", ", list);
This will convert list values into string and with that you can achieve this. I know this is very late but I posted because there is no solution provided that's why.

Here is an example:
public class TextViewMarquee extends Activity {
private TextView tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView) this.findViewById(R.id.tv);
tv.setSelected(true); // Set focus to the textview
}
}
The xml file with the textview:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:lines="1"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:textColor="#ff4500"
android:text="Simple application that shows how to use marquee, with a long text" />
</RelativeLayout>

Activity will run, but not show up (Android)?

I'm just trying to test some stuff with a splash screen. The strangest thing happens when I run the app though. I can see my Log messages in the LogCat, but the activity itself won't show up. Once the loop finishes, it starts the next activity, which does in fact show up. If I comment out the UIThread, it will show up though. I know I'm doing something simple wrong, but I'm not sure what it is. Ideas?
XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:background="#000000">
<ImageView
android:id="#+id/logoIV"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="50dp"
android:paddingTop="50dp"
android:src="#drawable/logoa"
/>
Java:
public class Splash extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splash);
final ImageView logo = (ImageView) findViewById(R.id.logoIV);
final int[] anim = new int[6];
anim[0]=R.drawable.logoa;
anim[1]=R.drawable.logob;
anim[2]=R.drawable.logoc;
anim[3]=R.drawable.logod;
anim[4]=R.drawable.logoe;
anim[5]=R.drawable.logof;
runOnUiThread(new Runnable() {
int img = 0, counter=0;
boolean up = true;
public void run() {
while(counter<21){
logo.setImageResource(anim[img]);
if(up){
img++;
if(img>=5)
up=false;
}else{
img--;
if(img<=0)
up=true;
}
try{
Thread.sleep(150);
}catch (InterruptedException e){
e.printStackTrace();
}
counter++;
Log.e("Tag",Integer.toString(counter));
}
if(counter>=21){
Intent creditsIntent = new Intent(Splash.this, TitlePage.class);
creditsIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Splash.this.startActivity(creditsIntent);
}
}
});
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}

change your oncreate method like this
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splash);
final ImageView logo = (ImageView) findViewById(R.id.logoIV);
final int[] anim = new int[6];
anim[0] = R.drawable.logoa;
anim[1] = R.drawable.logob;
anim[2] = R.drawable.logoc;
anim[3] = R.drawable.logod;
anim[4] = R.drawable.logoe;
anim[5] = R.drawable.logof;
Thread t = new Thread(new Runnable()
{
int img = 0, counter = 0;
boolean up = true;
#Override
public void run()
{
while (counter < 21)
{
runOnUiThread(new Runnable()
{
public void run()
{
logo.setImageResource(anim[img]);
}
});
if (up)
{
img++;
if (img >= 5)
up = false;
}
else
{
img--;
if (img <= 0)
up = true;
}
try
{
Thread.sleep(150);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
counter++;
Log.e("Tag", Integer.toString(counter));
}
if (counter >= 21)
{
runOnUiThread(new Runnable()
{
public void run()
{
Intent creditsIntent = new Intent(Splash.this, TitlePage.class);
creditsIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Splash.this.startActivity(creditsIntent);
}
});
}
}
});
t.start();
}

instead of calling runOnUiThread directly do the following:
new Timer().schedule(new TimerTask()
{
#Override
public void run()
{
runOnUiThread(new Runnable()
{
int img = 0, counter=0;
.....
}
}
}, 1000);
I'm not sure if your animation will work, but surely your activity will show up.
