in if(saveInstanceState != null) I am trying to save the changes of the text in Text Views that happened by whoWon() method to save it in while user rotate the phone and get it back as it was before rotation but it shows me an error that says getText() in TextView cannot be applied to (java.lang.string) , I tried to add .toString() but it didn't work.

getText() doesn't take a parameter. mTicTacTextViews[i].getText() returns the text in the view. Are you trying to set the text in the view? If so, you want setText(CharSequence), not CharSequence getText().

I have <> and <> buttons in my quiz app, but if the user is in the first question since there is no previous question there should be toast which says "this is the first question" and the same with <>button.
Here is my code for buttons (which is incorrect):
mNextButton = (Button)findViewById(R.id.next_button);
mNextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mCurreentIndex=0;
if (mCurreentIndex>mQuestionBank.length){
Toast.makeText(QuizActivity.this,R.string.last_question,Toast.LENGTH_LONG).show();
}
updateQuestion();
}
});
mPreviousButton = (Button)findViewById(R.id.previous_button);
mPreviousButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mCurreentIndex--;
if (mCurreentIndex<mQuestionBank.length){
Toast.makeText(QuizActivity.this, R.string.first_question,Toast.LENGTH_LONG).show();
}
updateQuestion();
}
});
mNextButton = (Button)findViewById(R.id.next_button);
mNextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//mCurreentIndex=0;// not valid
if (mCurreentIndex>=mQuestionBank.length){
Toast.makeText(QuizActivity.this,getString(R.string.last_question),Toast.LENGTH_LONG).show();
return;
}
mCurreentIndex++;
updateQuestion();
}
});
mPreviousButton = (Button)findViewById(R.id.previous_button);
mPreviousButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mCurreentIndex<=0){
Toast.makeText(QuizActivity.this, getString(R.string.first_question),Toast.LENGTH_LONG).show();
return;
}
mCurreentIndex--;
updateQuestion();
}
});
Try this
mPreviousButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mCurreentIndex<=0){
Toast.makeText(QuizActivity.this, R.string.first_question,Toast.LENGTH_LONG).show();
}else{
mCurreentIndex--;
updateQuestion();
}
}
});
mNextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mCurreentIndex>=mQuestionBank.length){
Toast.makeText(QuizActivity.this,getString(R.string.last_question),Toast.LENGTH_LONG).show();
}else{
mCurreentIndex++;
updateQuestion();
}
}
});
You have just display toast message but next statement also execute after displaying toast. For your solution you need to use "return" or if..else block.
mNextButton = (Button)findViewById(R.id.next_button);
mNextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mCurreentIndex=0;

return;

I have a program with 10 songs

and I tried to do this method in every onClick
public void resetseek(){
if(seekbar.getProgress() > 0)
{
seekbar.setProgress(0);
}
}
Normally one would use
seekbar.setProgress(0);
to reset a progress bar it to it's initial position.
I see you have posted your code as an answer instead of editing your question.
One big issue with your code is that you call Thread.start() more than once, which is illegal.
Also I wouldn't update the ProgressBar in a separate thread, instead you could just do it on the UI thread.
An alternate approach can be read in this question MediaPlayer, ProgressBar

Hello i'm creating an app to scan buisness cards, it has lot of views but one works very slow it has 19 buttons. Is it possible that slow working of my app is caused by this number of buttons? I've tried to put listeners outside of onCreate but it didn't help. This is my java file conected to this view:

The number of buttons by itself is not a likely cause of slowness. However, from the code it seems as if many actions from listeners (ie contact.savedata_nr) might be running on the main/UI thread which could cause slowness, depending on what happens when these methods are called. As mentioned in the comment, creating Bitmap might be better task to be carried out in the background as well.
To fix this, you should review your code and see what can be run in the background thread instead. Operations like saving can be done on the background thread, and then any updates to the GUI after these should be carried out on UI thread. If the background operation takes a long time, it's a good idea to up a progress indicator to show the user that something is happening and that the screen isn't just stuck.
You can read about Android threading here.
The basic example would be:
new Thread(new Runnable()
{
public void run()
{
//put background code here
contact.save(...)
//after background task is finished, update the UI
runOnUiThread(new Runnable()
{
#Override
public void run()
{
//put UI code here
textview.setText(...);
}
});
}
}).start();
