How to make customize mediacontroller for videoview

I make whole video player app but stuck at mediacontroller. I want to show my own mediacontroller with different button, not the default one. It's 4rth day, i'm just trying to make my own mediacontroller but didn't succeed.
I succeed by doing it with surfaceview but i want to use it with videoview.
I try the following code.
public class MyMediaController extends MediaController {

Plz someone suggest my the right way to do it. I realy need help.

What is the easiest way to update a textView from a service?

I am making an app which consists of an activity and a service. By pressing a button the service is started, it collects data in the background from a sensor and classifies it and outputs a string. I want to display the string in a textView. Right now I can see in the log that the variable is updated 2 times every second, but when I try and update the textView from the service class nothing is happening unless I press the button, whenever I press the button, the string is displayed in the textView.
What is the easiest solution here? I tried to make the textView static and it still can't update it. Can you make it so that the view is updated automatically every second? Can I add a listener somehow? Since I am not very experienced I would like an easy solution that does not have to be a "good" one.
Here is my code
Activity:
public class CollectorActivity extends Activity {
private enum State {
IDLE, COLLECTING, TRAINING, CLASSIFYING
};
private final String[] mLabels = { Globals.CLASS_LABEL_STANDING,
Globals.CLASS_LABEL_WALKING, Globals.CLASS_LABEL_RUNNING,
Globals.CLASS_LABEL_OTHER };
private RadioGroup radioGroup;
private final RadioButton[] radioBtns = new RadioButton[4];
private Intent mServiceIntent;
private File mFeatureFile;
public static TextView mCurrentLabel;
private State mState;
private Button btnDelete;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
radioGroup = (RadioGroup) findViewById(R.id.radioGroupLabels);
radioBtns[0] = (RadioButton) findViewById(R.id.radioStanding);
radioBtns[1] = (RadioButton) findViewById(R.id.radioWalking);
radioBtns[2] = (RadioButton) findViewById(R.id.radioRunning);
radioBtns[3] = (RadioButton) findViewById(R.id.radioOther);
btnDelete = (Button) findViewById(R.id.btnDeleteData);
mCurrentLabel = (TextView) findViewById(R.id.textView);
mState = State.IDLE;
mFeatureFile = new File(getExternalFilesDir(null),
Globals.FEATURE_FILE_NAME);
mServiceIntent = new Intent(this, SensorsService.class);
}
public void onCollectClicked(View view) {
if (mState == State.IDLE) {
mState = State.COLLECTING;
((Button) view).setText(R.string.ui_collector_button_stop_title);
btnDelete.setEnabled(false);
radioBtns[0].setEnabled(false);
radioBtns[1].setEnabled(false);
radioBtns[2].setEnabled(false);
radioBtns[3].setEnabled(false);
int acvitivtyId = radioGroup.indexOfChild(findViewById(radioGroup
.getCheckedRadioButtonId()));
String label = mLabels[acvitivtyId];
Bundle extras = new Bundle();
extras.putString(Globals.CLASS_LABEL_KEY, label);
mServiceIntent.putExtras(extras);
startService(mServiceIntent);
} else if (mState == State.COLLECTING) {
mState = State.IDLE;
((Button) view).setText(R.string.ui_collector_button_start_title);
btnDelete.setEnabled(true);
radioBtns[0].setEnabled(true);
radioBtns[1].setEnabled(true);
radioBtns[2].setEnabled(true);
radioBtns[3].setEnabled(true);
stopService(mServiceIntent);
((NotificationManager) getSystemService(NOTIFICATION_SERVICE)).cancelAll();
}
}
public void onDeleteDataClicked(View view) {
if (Environment.MEDIA_MOUNTED.equals(Environment
.getExternalStorageState())) {
if (mFeatureFile.exists()) {
mFeatureFile.delete();
}
Toast.makeText(getApplicationContext(),
R.string.ui_collector_toast_file_deleted,
Toast.LENGTH_SHORT).show();
}
}
#Override
public void onBackPressed() {
if (mState == State.TRAINING) {
return;
} else if (mState == State.COLLECTING || mState == State.CLASSIFYING) {
stopService(mServiceIntent);
((NotificationManager) getSystemService(NOTIFICATION_SERVICE))
.cancel(Globals.NOTIFICATION_ID);
}
super.onBackPressed();
}
#Override
public void onDestroy() {
// Stop the service and the notification.
// Need to check whether the mSensorService is null or not.
if (mState == State.TRAINING) {
return;
} else if (mState == State.COLLECTING || mState == State.CLASSIFYING) {
stopService(mServiceIntent);
((NotificationManager) getSystemService(NOTIFICATION_SERVICE))
.cancelAll();
}
finish();
super.onDestroy();
}
And this is the "doInBackground" method in my service class. The line "CollectorActivity.mCurrentLabel.setText(classification);" is the problem. I want this to update the textView continously.
public class OnSensorChangedTask extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... arg0) {
Instance inst = new DenseInstance(mFeatLen);
inst.setDataset(mDataset);
Instance inst2 = new DenseInstance(65);
int blockSize = 0;
FFT fft = new FFT(Globals.ACCELEROMETER_BLOCK_CAPACITY);
double[] accBlock = new double[Globals.ACCELEROMETER_BLOCK_CAPACITY];
double[] re = accBlock;
double[] im = new double[Globals.ACCELEROMETER_BLOCK_CAPACITY];
double max = Double.MIN_VALUE;
while (true) {
try {
// need to check if the AsyncTask is cancelled or not in the while loop
if (isCancelled () == true)
{
return null;
}
// Dumping buffer
accBlock[blockSize++] = mAccBuffer.take().doubleValue();
if (blockSize == Globals.ACCELEROMETER_BLOCK_CAPACITY) {
blockSize = 0;
testList = new ArrayList<Double>();
// time = System.currentTimeMillis();
max = .0;
for (double val : accBlock) {
if (max < val) {
max = val;
}
}
fft.fft(re, im);
for (int i = 0; i < re.length; i++) {
double mag = Math.sqrt(re[i] * re[i] + im[i]
* im[i]);
inst.setValue(i, mag);
testList.add(i,mag);
im[i] = .0; // Clear the field
}
// Append max after frequency component
inst.setValue(Globals.ACCELEROMETER_BLOCK_CAPACITY, max);
inst2.setValue(Globals.ACCELEROMETER_BLOCK_CAPACITY, max);
testList.add(max);
classificationIndex = WekaClassifier.classify(testList.toArray());
classification = testLabel.get((int) classificationIndex);
CollectorActivity.mCurrentLabel.setText(classification);
inst.setValue(mClassAttribute, mLabel);
mDataset.add(inst);
Log.i("new instance", mDataset.size() + "");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}

In doInBackground(Void... arg0) change CollectorActivity.mCurrentLabel.setText(classification); to publishProgress(classification); then change second argument from Void to String: public class OnSensorChangedTask extends AsyncTask<Void, Srting, Void> and add onProgressUpdate().
Finally your code should looks like:
public class OnSensorChangedTask extends AsyncTask<Void, Srting, Void> {
#Override
protected Void doInBackground(Void... arg0) {
//...
publishProgress(classification);
//...
}
#Override
protected Void onProgressUpdate(String... classification) {
CollectorActivity.mCurrentLabel.setText(classification[0]);
}

Countdown timer, points and incorrect multiplying

I have this code as a method:
String resultTimeString = ct.toString()
if(resultTimeString.length() == 2 ){
resultTime1ASCII = resultTimeString.charAt(0);
resultTime2ASCII = resultTimeString.charAt(1);
resultTime1 = (int)resultTime1ASCII - 48;
resultTime2 = (int)resultTime2ASCII - 48;
resultTime = resultTime1 + resultTime2;
}
else{
resultTime1ASCII = resultTimeString.charAt(0);
resultTime1 = (int)resultTime1ASCII - 48;
resultTime = resultTime1;
}
punkty = punkty * resultTime;
//Globals.setScore(punkty);
ct.cancel();
The problem is in counting. Final score ("punkty") isn't multiply punkty and resultTime and I don't know why. Variable punkty is define as a points from giving a good answer.
Timer count down from 60 to 0.

You have said that the final score always remains 0.
The only way this could be happening is when you have initialized punkty as 0.
Each time, it multiplies by 0, and remains 0.
You should initialize punkty as 1. Then your code will work.

How to create game loop for Android Wear app

What I'm trying to do is make an version of the game Simon for android wear. I don't want to use libgdx, tho I could if I have no other choice.
The way the game works is that the computer shows a button sequence to the player and then the player is to repeat the sequence back. I've got it all working fine except for I can't seem to animate a sequence to the player.
What I have is a random number generator. Using the number generated I want to change the color of the button background for a small time, then change it back. And I loop this a set number of times. I've tried SystemClock.sleep(500), but it just runs the loop before even showing the app.
The main problem is that everything has to be done inside an onLayoutInflated because of how wear has to choose between round and square faces. And this has to be done in the onCreate method as far as I know.
Does anyone know a way of doing some sort of game loop and/or animation sequence for android wear.
P.S. I will append my code as soon as I fix it. I've been fiddling with it a lot.

You should not use SystemClock.sleep() as you are blocking the UI thread. Probably this is the cause that the animation is done before showing the activity (The activity will not show until onCreate() finishes). This can also cause the famous ANR dialog.
You can use Handlers to do the work later without blocking the UI thread:
private Handler mHandler;
private int
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mHandler = new Handler();
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
computerTurnDown();
}
}, 500); //Delay time in ms
...
}
private void computerTurnDown(){
final int val = random.nextInt(4);
if (!mOverlay.isShown()) {
//Computer shows sequence
switch (val) {
case 0:
mTopLeft.getBackground().setColorFilter(GREEN_DOWN, PorterDuff.Mode.MULTIPLY);
System.out.println(val);
break;
case 1:
mTopRight.getBackground().setColorFilter(RED_DOWN, PorterDuff.Mode.MULTIPLY);
System.out.println(val);
break;
case 2:
mBotLeft.getBackground().setColorFilter(YELLOW_DOWN, PorterDuff.Mode.MULTIPLY);
System.out.println(val);
break;
case 3:
mBotRight.getBackground().setColorFilter(BLUE_DOWN, PorterDuff.Mode.MULTIPLY);
System.out.println(val);
break;
default:
break;
}
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
computerTurnUp(val);
}
}, 500);
}
private void computerTurnUp(){
switch (val) {
case 0:
mTopLeft.getBackground().setColorFilter(GREEN_UP, PorterDuff.Mode.MULTIPLY);
break;
case 1:
mTopRight.getBackground().setColorFilter(RED_UP, PorterDuff.Mode.MULTIPLY);
break;
case 2:
mBotLeft.getBackground().setColorFilter(YELLOW_UP, PorterDuff.Mode.MULTIPLY);
break;
case 3:
mBotRight.getBackground().setColorFilter(BLUE_UP, PorterDuff.Mode.MULTIPLY);
break;
default:
break;
}
compSeq.add(val);
if (compSeq.size() < level){
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
computerTurnDown();
}
}, 300);
}else{
isPlayerTurn = true;
}
}
Whenever you want to do some work delayed use mHandler.postDelayed() and put the code in run() method.
To check the user should be done in the button listener because the way you have currently the "while (playSeq.size() < level)" will block the thread.
private void setupButtonActions(final ImageButton button, final int tint_up, final int tint_down) {
//create button listeners and tints
button.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (isPlayerTurn) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
button.getBackground().setColorFilter(tint_down, PorterDuff.Mode.MULTIPLY);
} else if (event.getAction() == MotionEvent.ACTION_UP) {
button.getBackground().setColorFilter(tint_up, PorterDuff.Mode.MULTIPLY);
}
//Enter correct sequence value
int val = 4;
if (button == mTopLeft) {
val = 0;
} else if (button == mTopRight) {
val = 1;
} else if (button == mBotLeft) {
val = 2;
} else if (button == mBotRight) {
val = 3;
}
playSeq.add(val);
if(playSeq.size() < level) {
//Check for correct input
if (playSeq.size() > 0 && (playSeq.get(playSeq.size()-1) != compSeq.get(playSeq.size()-1))) {
isRunning = false;

Sharing Intent Not working Properly

I have one quote application. I have implemented share and copy function in it. I am facing issue is that I am not getting shared first time sharing quote. Means if there 50 quote in list and if I try to share any quote from list than it is not sharing anything. after that if I move on another quote and try to sharing than its working fine. I have same issue in copy function also. I also face some time issue like if I share quote number 50 than its sharing another number quote. Please help me for solve the bug. Thanks
