I am trying to compare 2 scores that I have made oldScore and best_score(both in Main_Screen). I think the problem is that the ints are not saving properly. There are no errors but if the best_Score is lower than the old_score it still changes it in the textview even though the best_score should be higher than the old_score. Hopefully I can learn from this :)
Main_Screen
public class Main_Screen extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
getSupportActionBar().hide();
//SETS CUSTOM FONT
TextView main_screen_titleone = (TextView)findViewById(R.id.main_screen_titleone);
TextView main_screen_titletwo = (TextView)findViewById(R.id.main_screen_titletwo);
TextView best_score_tv = (TextView)findViewById(R.id.best_score_tv);
TextView best_score_number_tv = (TextView)findViewById(R.id.best_score_number_tv);
Typeface myCustomFont = Typeface.createFromAsset(getAssets(), "fonts/LemonMilk.otf");
main_screen_titleone.setTypeface(myCustomFont);
main_screen_titletwo.setTypeface(myCustomFont);
best_score_tv.setTypeface(myCustomFont);
best_score_number_tv.setTypeface(myCustomFont);
//******************;
int best_score = retrieveInt("BEST_SCORE");
int oldScore = Integer.valueOf(best_score_number_tv.getText().toString());
if (best_score > oldScore){
best_score_number_tv.setText(best_score + "");
}
}
public void startTheGame(View view){
Intent intent = new Intent(this, press_screen.class);
startActivity(intent);
}
public int retrieveInt(String key){
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
return sp.getInt(key, 0);
}
Press_Screen
public class press_screen extends ActionBarActivity {
private int time_left;
private int amountOfTapsNumber;
private int bestScore;
TextView amountOfTaps;
TextView timeLeftNumber;
TextView time_left_tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_press_screen);
getSupportActionBar().hide();
amountOfTaps = (TextView)findViewById(R.id.amount_of_taps);
timeLeftNumber = (TextView)findViewById(R.id.time_left_number_tv);
time_left_tv = (TextView)findViewById(R.id.time_left_tv);
Typeface myCustomFont = Typeface.createFromAsset(getAssets(), "fonts/LemonMilk.otf");
amountOfTaps.setTypeface(myCustomFont);
timeLeftNumber.setTypeface(myCustomFont);
time_left_tv.setTypeface(myCustomFont);
timer.start();
}
//Create Timer
CountDownTimer timer = new CountDownTimer(21000, 1000) {
#Override
public void onTick(long millisUntilFinished) {
timeLeftNumber = (TextView) findViewById(R.id.time_left_number_tv);
time_left = Integer.valueOf(timeLeftNumber.getText().toString()) - 1;
timeLeftNumber.setText(time_left + "");
}
#Override
public void onFinish() {
if(amountOfTapsNumber > bestScore){
bestScore = amountOfTapsNumber;
saveInfo("BEST_SCORE", bestScore);
}
TextView best_score_number_tv = (TextView)findViewById(R.id.best_score_number_tv);
Intent goBackToMainActivity = new Intent(press_screen.this, Main_Screen.class);
startActivity(goBackToMainActivity);
}
};
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_press_screen, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void triggerTapOnMainButton(View view) {
amountOfTaps = (TextView) findViewById(R.id.amount_of_taps);
amountOfTapsNumber = Integer.valueOf(amountOfTaps.getText().toString()) + 1;
amountOfTaps.setText(amountOfTapsNumber + "");
}
public void saveInfo(String key, int bestScore){
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor edit = sp.edit();
edit.putInt("BEST_SCORE", bestScore);
edit.commit();
}
}
When your timer finishes, you send your tapsNumber on the Intent to MainActivity, like this:
Intent goBackToMainActivity = new Intent(press_screen.this, Main_Screen.class);
Bundle bundle = new Bundle();
bundle.putInt("lastScore", amountOfTapsNumber);
goBackToMainActivity.putExtras(bundle);
startActivity(goBackToMainActivity);
Then, in your MainActivity onCreate(), check if your Intent has the oldScore. If it does, compare it to the best_score.
int lastScore = 0;
if(getIntent() !=null && getIntent().getIntExtra("lastScore",0)>0)
lastScore = getIntent().getIntExtra("lastScore",0);
//comparing the lastScore with the bestScore
if (lastScore > best_Score){
best_score_number_tv.setText(lastScore + "");
}
else{
best_score_number_tv.setText(best_Score + "");
}
This way your bestScore will be updated if your lastScore is higher than your old best_score.

I have read many tutorial about CRUD SQLite, but most of them use Cursor to get values data and Button to call EditScreen. Any one lead me how to implementing i.putExtras in my Edit Menu Toolbar, please? I want to show again my data in EditText Form.
public class DetailStaffActivity extends AppCompatActivity {
private DBHandler dbHandler;
private TextView txt_resultnomor, txt_resultnama, txt_resulttempatlahir, txt_resulttanggallahir;
private List<Staff> staffList = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.staff_details);
dbHandler = new DBHandler(this);
//ambil data
Intent i=getIntent();
final String nomor=i.getExtras().getString("nomor");
final String nama=i.getExtras().getString("nama");
final String tempatlahir = i.getExtras().getString("tempat_lahir");
final String tanggallahir=i.getExtras().getString("tanggal_lahir");
//inisialisasi dulu
txt_resultnomor = (TextView) findViewById(R.id.txt_resultnomor);
txt_resultnama = (TextView) findViewById(R.id.txt_resultnama);
txt_resulttempatlahir = (TextView) findViewById(R.id.txt_resulttempatlahir);
txt_resulttanggallahir = (TextView) findViewById(R.id.txt_resulttanggallahir);
//set inisial dengan data yang telah diambil di dengan intent
txt_resultnomor.setText(nomor);
txt_resultnama.setText(nama);
txt_resulttempatlahir.setText(tempatlahir);
txt_resulttanggallahir.setText(tanggallahir);
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_detail, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_edit) {
public void onItemClick(View view, int position) { //here, error when set position in this menu//
// TODO Handle item click
Intent in = new Intent(this, UpdateStaffActivity.class);
Staff staff = staffList.get(position);
String getNama = staffList.get(position).getNama();
in.putExtra("nama", getNama);
startActivity(in);
return true;
}
if (id == R.id.action_delete) {
return true;
}
if (id == R.id.action_settings) {
// Intent i = new Intent(this, About.class);
//startActivity(i);
}
return super.onOptionsItemSelected(item);
}
}
Please, how implementing putExtras in
if (id == R.id.action_edit) { }
I got error when set position in this menu. Thanks.
Just remove this line
public void onItemClick(View view, int position) { //here, error when set position in this menu//
// TODO Handle item click
Intent in = new Intent(this, UpdateStaffActivity.class);
Staff staff = staffList.get(position);
String getNama = staffList.get(position).getNama();
And write like this.
if (id == R.id.action_edit) {
Intent in = new Intent(this, UpdateMuriddActivity.class);
in.putExtra("nomor", txt_resultnomor.getText().toString());
in.putExtra("nama", txt_resultnama.getText().toString());
in.putExtra("tempat_lahir", txt_resulttempatlahir.getText().toString());
startActivity(in);
Hope its help.
So i have a slight problem. I have a feeling its something simple that i must be overlooking. In my second fragment im writing to sharedpreferences a certain number of keys and applying() afterwords. After i have finished writing my data to the sharedpreferences, i replace the current fragment(fragment#2), with the home fragment(fragment#1). Upon loading this fragment i call readPreferences(), which should read the data stored ealier and write the data to the various textviews i have on the home fragment. This does not happen. Im unsure at this time if its due to a write error or a read error. your help is as always, appreciated. Thanks.

While saving string on SharedPreferences make sure that you are not saving null. It will instead clear the preference key.
prefEditor.putString(alarmOccuranceKey, occurance);
Make sure that occurance is not null.
Please use commit() to save the data. Also you can create a simple reusable class for SharedPreferences. Please refer to my customized class for the same: https://codebegetter.wordpress.com/2016/08/04/shared-preferences-reusable-class/
Based on the comments in one of the answers it looks like you have applied a solution. However, based on the code you posted here was the issue:
You are not storing and retrieving values from the same SharedPreferences file. When you store values you are using a custom named SharedPreferences file. When you try to retrieve those values you are referencing the SharedPreferences file that is specific to the Activity which hosts your secondFragment. (Which, in a way, is actually custom named as well...the framework bases it on your Activity name).
When you write values to SharedPreferences in your secondFragment you call:
sharedPreferences = getActivity().getSharedPreferences(alarmPreferences, Context.MODE_PRIVATE);
//...
prefEditor = sharedPreferences.edit();
When you attempt to read those values in your HomeFragment you call:
sharedPreferences = getActivity().getPreferences(Context.MODE_PRIVATE);
These two code snippets don't reference the same SharePreferences file. The most direct solution would be to update the code in your HomeFragment so that you obtain the same SharePreferences file where you stored your values like so:
sharedPreferences = getActivity().getSharedPreferences(alarmPreferences, Context.MODE_PRIVATE);

Your help is appreciated. Thanks!
Based on discussion and answer given by #Rahul Tiwari...do the following modifications in your code.....
First create the instance TextView variable
//your instance variables
int count;
TextView tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
//your code...
tv = (TextView) findViewById(R.id.textView1);
count = getSharedPreferences("NAME_FOR_SHARED_PREFERENCES", Context.MODE_PRIVATE).getInt("count_key", 0);
updateTextView();
}
void updateTextView(){
tv.setText(""+count);
}
//your code till here....
public void createNote(View v) {
NoteItem note = NoteItem.getNew();
SharedPreferences sharedPref = getSharedPreferences("NAME_FOR_SHARED_PREFERENCES", Context.MODE_PRIVATE);
sharedPref.edit().putInt("count_key", ++count).commit();
updateTextView()
/*for intial testing commenting this code block
Intent intent = new Intent(this, NoteEditorActivity.class);
intent.putExtra(NoteItem.KEY, note.getKey());
intent.putExtra(NoteItem.TEXT, note.getText());
startActivityForResult(intent, EDITOR_ACTIVITY_REQUEST);
*/
}
//your code.
Then you can start app multiple times and check want is the count value.
Note: When naming your shared preference files, you should use a name
that's uniquely identifiable to your app, such as
"com.example.myapp.PREFERENCE_FILE_KEY" for more detail refer
your counter is not being refreshed as you are not changing text in your text view after changing the count.
you need to use
TextView tv = (TextView) findViewById(R.id.textView1);
tv.setText(""+count);
at the end of your createNote function
use getDefaultSharedPreferences to access your shared preference across activities in your app. refer this answer for example.
I have the ArrayList...
ArrayList<ColorSaver> tempList = new ArrayList<ColorSaver>();
and I want it so that when the user closes the app or leaves the app, all the ColorSaver objects in the ArrayList will be there when the user reopens the app. I would prefer to use the SharedPreferences but I can't do that because the list is a custom object...
I have looked around and found out that I can do a serializable but I tried that and failed horribly, so if somebody could guide me through the serializable deal that would be great. Oh and where do I put the code, like in onCreate() in my mainActivity or in the activity that is displaying the ArrayList

I am greatful of any help!
Take a look at Android's Parcelable implementation.
So, I'm just guessing on your ColorSaver class since it wasn't posted, but you would implement it the following way:
ColorSaver.java
public class ColorSaver implements Parcelable {
private String mName;
private int mRed;
private int mGreen;
private int mBlue;
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel out, int flags) {
out.writeString(mName);
out.writeInt(mRed);
out.writeInt(mGreen);
out.writeInt(mBlue);
}
public static final Parcelable.Creator<ColorSaver> CREATOR
= new Parcelable.Creator<ColorSaver>() {
public ColorSaver createFromParcel(Parcel in) {
return new ColorSaver(in);
}
public ColorSaver[] newArray(int size) {
return new ColorSaver[size];
}
};
private ColorSaver(Parcel in) {
mName = in.readString();
mRed = in.readInt();
mGreen = in.readInt();
mBlue = in.readInt();
}
}
MyActivity.java
public class MyActivity extends Activity {
private static final String COLOR_SAVER_LIST = "com.example.android.ColorSaverList";
private List<ColorSaver> colorSaverList;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null && savedInstanceState.containsKey(COLOR_SAVER_LIST)) {
colorSaverList = new ArrayList<ColorSaver>();
colorSaverList = savedInstanceState.getParcelableArrayList(COLOR_SAVER_LIST);
}
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putParcelableArrayList(COLOR_SAVER_LIST, colorSaverList);
}
}
I have 10 TextViews in my code and i would like to change font size on all of them. On my layout i have used a #style to define common properties however i don't know how to change them all from code once layout is on screen.
What i dont want to do is update N objects but write only in one place. I know that i could use applyTheme but this assumes that you have an XML theme somewhere on disk, i want to be able to scale fonts to any size so this solution is not practical.
Any idea?
See similar questions:
How to programmatically setting style attribute in a view
android dynamically change style at runtime
android : set textView style at runtime
It sounds like its not possible to change an individual style element at runtime. You could apply a different theme, but then you would need a different theme for every font size you want to support. Annoying, but possible.
Otherwise, you have to come up with a way to reduce the pain of updating all of the textViews. You could store the size in your application class, so it is accessible by all of your activities, and then in onCreate update the size for each TextView.
Here is the whole code for dynamically change font size and theme
MainActivity:
public class MainActivity extends AppCompatActivity {
TextView textViewMain;
Button buttonChangeFont;
int size, value;
SharedPreferences pref;
SharedPreferences.Editor editor;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
pref = getApplicationContext().getSharedPreferences("MyPref", 0);
changeTheme();
setContentView(R.layout.activity_main);
//References
textViewMain = findViewById(R.id.textViewMain);
buttonChangeFont = findViewById(R.id.buttonChangeFont);
//Set Onclick on button
buttonChangeFont.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent goToPreview = new Intent(MainActivity.this, PreviewActivity.class);
startActivity(goToPreview);
}
});
int value = pref.getInt("value", 0);
textViewMain.setTextSize(value);
}
private void changeTheme() {
String theme = pref.getString("theme", "default");
if (theme != null && theme.equals("default")) {
setTheme(R.style.AppTheme);
} else if (theme != null && theme.equals("black")) {
setTheme(R.style.BlackTheme);
} else {
setTheme(R.style.BlueTheme);
}
}
public void getSize() {
editor = pref.edit();
size = getIntent().getIntExtra("size", 14);
if (size == 14) {
value = 14;
editor.putInt("value", value);
} else if (size == 20) {
value = 20;
textViewMain.setTextSize(value);
editor.putInt("value", value);
} else {
value = 30;
textViewMain.setTextSize(value);
editor.putInt("value", value);
}
editor.commit();
