Android media player with list view and service

Android media player with list view and service - java

I have implemented an Android media player that is clicking on songs text view will display the layout. The layout displayed with play pause .. and clicking on play stop works well. Here I am thinking in users perspective to implement the below.
Clicking on songs text view should display the songs in list view and in the bottom of the layout small controls should display with play pause and stop
It should play even when other application is opened.
To achieve the point 2 I used media player service and for point 1, I used a `ListView' but not successfully implemented. Below is the code which play the song and and go till end. From this point can anyone please help me to implement list view songs with service?
public class Songs extends Activity {
private MediaPlayer mediaPlayer;
public TextView songName, duration;
private double timeElapsed = 0, finalTime = 0;
private int forwardTime = 2000, backwardTime = 2000;
private Handler durationHandler = new Handler();
private SeekBar seekbar;
private Context context;
private int getCurrentPos=0;
private int[] songs={R.raw.sample_song,R.raw.sleepaway};
#Override
protected void onCreate(Bundle savedInstanceState) {
context=getApplicationContext();
super.onCreate(savedInstanceState);
setContentView(R.layout.mediaplayer);
initializeViews();
}
public void initializeViews(){
songName = (TextView) findViewById(R.id.songName);
mediaPlayer = MediaPlayer.create(this, songs[getCurrentPos]);
mediaPlayer.setLooping(true);
finalTime = mediaPlayer.getDuration();
duration = (TextView) findViewById(R.id.songDuration);
seekbar = (SeekBar) findViewById(R.id.seekBar);
songName.setText("Sample_Song.mp3");
seekbar.setMax((int) finalTime);
seekbar.setClickable(false);
}
// play mp3 song
public void play(View view) {
mediaPlayer.start();
timeElapsed = mediaPlayer.getCurrentPosition();
seekbar.setProgress((int) timeElapsed);
durationHandler.postDelayed(updateSeekBarTime, 100);
}
private Runnable updateSeekBarTime = new Runnable() {
public void run() {
//get current position
timeElapsed = mediaPlayer.getCurrentPosition();
//set seekbar progress
seekbar.setProgress((int) timeElapsed);
//set time remaing
double timeRemaining = finalTime - timeElapsed;
// duration.setText(String.format("%d min, %d sec", 12, TimeUnit.MILLISECONDS.toSeconds((long) timeRemaining) - 12));
//repeat yourself that again in 100 miliseconds
durationHandler.postDelayed(this, 100);
}
};
// pause mp3 song
public void pause(View view) {
mediaPlayer.pause();
}
// go forward at forwardTime seconds
public void forward(View view) {
//check if we can go forward at forwardTime seconds before song endes
if ((timeElapsed + forwardTime) <= finalTime) {
timeElapsed = timeElapsed + forwardTime;
//seek to the exact second of the track
mediaPlayer.seekTo((int) timeElapsed);
}
}
// go backwards at backwardTime seconds
public void rewind(View view) {

if ((timeElapsed - backwardTime) > 0) {

}

Recyclerview is Scrolling when media Player is playing. How can i fix it?

I'm developing a ChatApp with the function of Audio Messages. The Recording and playing of this Audio Messages are working very well, but if i click on Play Button the Recyclerview is scrolling up. Anyone have an idea?

android:layout_height="wrap_content"/>

Android Studio: how progress bar can fill up based on user input

I am using a progress bar sample from Github however I noticed that the progress bar fill is set to a fixed value. For example, if the step count goal is 10 (.java class) the man should be "10" in the .XML
My goal: when the user inputs their goal step count, the "10" should be variable and change depending on user input.
java snippet:
ProgressBar progressBar = (ProgressBar) this.findViewById(R.id.progressBar);
ObjectAnimator animation = ObjectAnimator.ofInt(progressBar, "progress", lastStep, stepCounter); //animate only from last known step to current step count
animation.setDuration(5000); // in milliseconds
animation.setInterpolator(new DecelerateInterpolator());
animation.start();
lastStep = stepCounter;
XML snippet
<ProgressBar
android:id="#+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="376dp"
android:layout_height="392dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:max="10"
android:progress="0"
android:progressDrawable="#drawable/circular" />
EDIT********************EDIT
Sorry maybe my question wasn't clear. To provide an example...if the users step goal is 500. I need the progress bar to fill respectively. Therefore, IF step_count = 250 then progress bar should be half full, IF step_count = 750 then should be 3/4 full. I need the progression to be respective to a variable value.

App Crashes when using setVisibility

As the title says,
When using startLabel.setVisibility(View.GONE);
The app Crashes and I am not sure how to fix
The Java code below.

}
box.setY(boxY);
}
public boolean onTouchEvent(MotionEvent me)
{
if (start_flg == false)
{
start_flg = true;
//Issue here with setting the visibility of the start
// startLabel.setVisibility(View.GONE);
timer.schedule(new TimerTask()
{
#Override

}, 0, 100);
}else {

{
action_flg = true;
}else if (me.getAction() == MotionEvent.ACTION_UP){

}
return true;

Anyone help appreciated to fix this issue, Thanks

Your startLabel is null (copy paste problem?^^). Replace this:
scoreLabel = (TextView) findViewById(R.id.startLabel);
with this:
startLabel = (TextView) findViewById(R.id.startLabel);

You should try cleaning your project !!

Try Clean your Project.
OR
Restart Eclipse.
Or
Check with All XML Resources you have used. Is their any missing things in your XML.
This case mostly happens when you have Something wrong with your XML Resources you are using.

Dynamic Graph of Sensor data with aChartEngine - Android

I have an application which connects to an external sensor via Bluetooth Low Energy. I have the data coming in as a dynamic string which I have split into three strings, then I have the strings converted into doubles.
I have been trying to graph the doubles dynamically for weeks now with various chart libraries such as
aChartEngine
AndroidPlot
and ChartDroid
I decided to go with aChartEngine mainly because I found a dynamic sample app that graphs random data. I have been trying to implement this sample app into mine. Then I am hoping to adapt it to graph my sensor data doubles.
Here is the code I am trying to implement at the moment:
public class XYChartBuilder extends Activity {
public static final String TYPE = "type";
private XYMultipleSeriesDataset mDataset = new XYMultipleSeriesDataset();
private XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
private XYSeries mCurrentSeries;
private XYSeriesRenderer mCurrentRenderer;
private String mDateFormat;
private Button mNewSeries;
private Button mAdd;
private GraphicalView mChartView;
private int index = 0;
static double x = 0;
static double y = 0;
protected Update mUpdateTask;
#Override

.getSerializable("dataset");

.getSerializable("renderer");
mCurrentSeries = (XYSeries) savedState
.getSerializable("current_series");
mCurrentRenderer = (XYSeriesRenderer) savedState
.getSerializable("current_renderer");
mDateFormat = savedState.getString("date_format");
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putSerializable("dataset", mDataset);
outState.putSerializable("renderer", mRenderer);
outState.putSerializable("current_series", mCurrentSeries);
outState.putSerializable("current_renderer", mCurrentRenderer);
outState.putString("date_format", mDateFormat);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.demo_opengl_acc);
mRenderer.setApplyBackgroundColor(true);
mRenderer.setBackgroundColor(Color.argb(100, 50, 50, 50));
mRenderer.setAxisTitleTextSize(16);
mRenderer.setChartTitleTextSize(20);
mRenderer.setLabelsTextSize(15);
mRenderer.setLegendTextSize(15);
mRenderer.setMargins(new int[] { 20, 30, 15, 0 });
mRenderer.setZoomButtonsVisible(true);
mRenderer.setPointSize(10);
mRenderer.setXTitle("TIME");
mRenderer.setYTitle("y");
mRenderer.setShowGrid(true);
String seriesTitle = "Series " + (mDataset.getSeriesCount() + 1);
XYSeries series = new XYSeries(seriesTitle);
mDataset.addSeries(series);
mCurrentSeries = series;
XYSeriesRenderer renderer = new XYSeriesRenderer();
mRenderer.addSeriesRenderer(renderer);
renderer.setPointStyle(PointStyle.CIRCLE);

The problem I have implementing the project is that it does not show up in the app at all.
There are no errors. It just doesn't display. I am just wondering if anyone can help. Or if you know any other basic dynamic graph tutorials, maybe for implementing into an existing project. I am 15 (edit - 16 now) and have only started java in the last couple of months. I am still only at the basics. If you post any code could you please explain it.
Thanks in advance,

The problem is with your layout, it is not designed well.
Use something like the following. You may need to adjust few things.
Your layout is not showing properly on small screen devices.I have edited ur layout and now its showing on small devices also.Please adjust height and other things according to ur requirement.
