Multiple Activities with one XML File

Multiple Activities with one XML File - android

I am making a music player application in android. The application has
MainActivity.java (with corresponding XML File:activity_main): This Activity has a listview that displays the list of all songs available.
PlayerScreen.java (with corresponding XML File:activity_player_screen): When a song is clicked on the first activity, this activity is launched and it plays that particular song. This activity has 3 Buttons (Play/Pause, NextSong, PreviousSong) and a seekbar.
Now this is where I am facing the problem
I have created a separate class (SeekBarThread.java) for implementing seekbar of the activity_player_screen using Threading.
The Problem is that when I call the start method for my thread class from PlayerScreen.java, nothing happens. No exception is thrown. The song keeps on playing but the widgets of the activity_player_screen stop working i.e. I can't pause the song aur play the next song. The seekbar also doesn't work.
I think I am not able to link the activity_player_screen file with both PlayerScreen.java and SeekBarThread.java properly.
This is the call to the Thread class from PlayerScreen.java
mySeekBarThread = new SeekBarThread(this, mySeekBar, mediaPlayer);
myThread = new Thread(mySeekBarThread);
myThread.start();
I don't really have an idea to get rid of the anomaly so I passed the seekbar object and mediaplayer object reference and the current context reference to the SeekBarThread class. But it didn't work.
Here is the SeekBarThread.java class code:
public class SeekBarThread implements Runnable{
private PlayerScreen myPlayerScreen;
private SeekBar seekBar;
private MediaPlayer mp;
private Context context;
public SeekBarThread(Context context, SeekBar seekBar, MediaPlayer mp) {
this.context = context;
this.seekBar = seekBar;
this.mp = mp;
}
public void run() {
((Activity)context).setContentView(R.layout.activity_player_screen);
seekBar.setMax(mp.getDuration());
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
mp.seekTo(seekBar.getProgress());
}
});
int totalduration = mp.getDuration();
int currentposition = 0;
while(currentposition < totalduration) {
try {
sleep(500);
currentposition = mp.getCurrentPosition();
seekBar.setProgress(currentposition);
}
catch(InterruptedException ex) {
ex.printStackTrace();
}
}
}
}

Most of the onCreate() code for this is class is dealing with which song to play based on the user's choice from the previous activity. And since the song is being played, i don't think there is a problem in that part of the code.

#prakhar, Going through the code, I have found the following issues:
1) In SeekBarThread class in run() method setContentView() should not set,as it is already set in the activity class, as your are not reinitializing the click listeners.
2) Also the seekbarchangeListener should not be set in run() method and should be set in the main activity itself, as it doesn't need reinitalizing all the time.
3) The important point here is that your are initializing the SeekBarThread class before the initialization of MediaPlayer and hence there is no action even after seeking the seekbar.
A detailed code with the above modifications rectified.

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;

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:

return VoiceViewHolder.createVoiceViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.lecture_voice_item_recycler, parent, false));

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();

}
});

Thread.sleep(1000);
} catch (InterruptedException e) {

};
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.

Want MediaPlayer to continue running when screen is locked

How could I make it so that my MediaPlayer continues to play even when the phone is locked and the screen is off, thinking it may have to do something of making it a service but not sure. If so how could I go about changing it to a service or is there a quicker easier fix?
Any help would be great!
Here is code:
public class player2 extends Activity implements Runnable {

Follow my tutorial below...In following tutorial i have stored .mp3 file in raw folder. if you have stored it in sd card and dynamically fetching that file then put its path in bundle and send it through intent which you can get in onStartCommand() method of your service.
MainActivity.java
public class MainActivity extends Activity implements OnClickListener {
Button startPlaybackButton, stopPlaybackButton;
Intent playbackServiceIntent;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startPlaybackButton = (Button) this.findViewById(R.id.StartPlaybackButton);
stopPlaybackButton = (Button) this.findViewById(R.id.StopPlaybackButton);
startPlaybackButton.setOnClickListener(this);
stopPlaybackButton.setOnClickListener(this);
playbackServiceIntent = new Intent(this, BackgroundAudioService.class);
}
public void onClick(View v) {
if (v == startPlaybackButton) {
startService(playbackServiceIntent);
finish();
} else if (v == stopPlaybackButton) {
stopService(playbackServiceIntent);
finish();
}
}
}
BackgroundAudioService.java
public class BackgroundAudioService extends Service implements OnCompletionListener {
MediaPlayer mediaPlayer;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
mediaPlayer = MediaPlayer.create(this, R.raw.abc);// YOUR FILE NAME
mediaPlayer.setOnCompletionListener(this);
Log.v("TEST", "1");
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (!mediaPlayer.isPlaying()) {
Log.v("TEST", "2");
mediaPlayer.start();
}
return START_STICKY;
}
public void onDestroy() {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
}
mediaPlayer.release();
}
public void onCompletion(MediaPlayer _mediaPlayer) {
stopSelf();
}
}

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.

android media player shows audio but no video

I had this problem and solved it by setting the type using this depreciated method.
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
Worth a try, and if it works you could investigate why the type isn't automatically set as it is supposed to be.

I had the same problem and it was due to the surface not being ready to play back video.
You should try and call playVideo() from the surfaceCreated() handler.
public void surfaceCreated(SurfaceHolder holder) {
runOnUiThread(new Runnable(){
public void run(){
playVideo();
}
});
}

I had this problem and solved it by adding in my release function visible=gone to surfaceview:
public void release() {
if (mMediaPlayer != null) {
setVisibility(View.GONE);
mMediaPlayer.reset();
mMediaPlayer.release();
mMediaPlayer = null;
mCurrentState = STATE_IDLE;}
}
and set visible=visible in onprepared function:
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
audio=false; video=false; int ty=mp.getTrackInfo().length;
for (int i=0; i<ty;i++)
{
if (mp.getAudioTrack()>-1) {audio=true;}
if (mp.getVideoTrack()>-1) {video=true;}
}
if (((audio==false)&&(skip==true))||((video==false)&&(skip2==true))||((video==true)&&(skip4==true)))
{ notifybar("...");
nexttr();} else {
if (vis==true) {
if (video==false) {
if (mVisualizerView.getVisibility()!=View.VISIBLE) {mVisualizerView.setVisibility(View.VISIBLE);}
mVisualizerView.link(videoView.getAudioSessionId());
vis2=true;
} else if (vis2==true){
mVisualizerView.release();
mVisualizerView.setVisibility(View.GONE);
vis2=false;
}}
//this
if (video==true) {
if (videoView.getVisibility()!=View.VISIBLE) {videoView.setVisibility(View.VISIBLE);}
} else {if (videoView.getVisibility()!=View.INVISIBLE) {videoView.setVisibility(View.INVISIBLE);}
}
