SharedPreferences in Android is generally used to store key=value pairs, not lists such as the one you describe. To store a value into SharedPreferences, you can do this:
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
Editor ed = sp.edit();
ed.putString("myKey", "myValue");
And then to retrieve a string key from SharedPreferences, you would do this:
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
String value = sp.getString("myKey", "");
You could have a comma-delimited list of favorite words stored in here, and just parse the list:
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
Editor ed = sp.edit();
ed.putString("favorites", "dog,cat,bird,fish");
And then to retrieve them:
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
String favorites = sp.getString("myKey", "");
String[] words = values.split(",");
System.out.println(Arrays.toString(words));
Then you have an array containing all of your favorite words.
[dog, cat, bird, fish]

You can rewrite this code of lines:
ProgressBar bar = (ProgressBar)findViewById(R.id.pbar);
Button button = (Button)findViewById(R.id.btn);
As:
public class MainActivity extends Activity {
Button button ;
ProgressBar bar ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bar = (ProgressBar)findViewById(R.id.pbar);
button = (Button)findViewById(R.id.btn);
.....
}}
Then you will not get null pointer exception.
This line
ProgressBar bar = (ProgressBar)findViewById(R.id.pbar);
Button button = (Button)findViewById(R.id.btn);
should be in your onCreate method
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ProgressBar bar = (ProgressBar)findViewById(R.id.pbar);
Button button = (Button)findViewById(R.id.btn);
}
Here is Complete Solution :
public class MainActivity extends Activity {
Button button;
ProgressBar bar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
button = (Button) findViewById(R.id.btn);
bar = (ProgressBar) findViewById(R.id.pbar);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
updateHandler.post(updateThread);
}
});
}
Handler updateHandler = new Handler() {
public void handleMessage(Message msg) {
bar.setProgress(msg.arg1);
updateHandler.post(updateThread);
}
};
Runnable updateThread = new Runnable() {
int i = 0;
#Override
public void run() {
// TODO Auto-generated method stub
System.out.println("------------");
i = i + 10;
Message msg = updateHandler.obtainMessage();
msg.arg1 = i;
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
updateHandler.sendMessage(msg);
if (i == 100) {
updateHandler.removeCallbacks(updateThread);
}
}
};

I am trying to make a simple drawing application, but am running into problems switching the paint color.Here is the tutorial I used to get to the point I am at. Here is my code:
Drawing_View.java
public class Drawing_View extends View {
private Path path = new Path();
private Paint paint = new Paint();
public String paint_color = "#FFBB00";
public Drawing_View(Context context, AttributeSet attrs) {
super(context, attrs);
paint.setAntiAlias(true);
paint.setStrokeWidth(5f);
paint.setColor(Color.parseColor(paint_color));
paint.setStyle(Paint.Style.STROKE);
paint.setStrokeJoin(Paint.Join.ROUND);
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawPath(path, paint);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
float eventY = event.getY();
float eventX = event.getX();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
// Set a new starting point
path.moveTo(eventX, eventY);
return true;
case MotionEvent.ACTION_MOVE:
// Connect the points
path.lineTo(eventX, eventY);
break;
default:
return false;
}
invalidate();
return true;
}
}
Here is the code for the activity the custom view sits inside.
Drawing_Main.java
public class Drawing_Main extends ActionBarActivity {
Button green_light,green_dark,blue_light,blue_dark,blue_verydark,purple,magenta,red,orange_dark,orange_light,orange_lightest,yellow,black;

As you can see I started exploring the sharedPreferences option, after my attempt to create a service failed. If a Service is the best option, how can I make Drawing_View.java constantly listen for color changes? Thanks everyone!
You could add a setPaintColor method to your Drawing_View class. That way, you would not need to use SharedPreferences
and you could just change the paint color in your onClickListeners.
Something like this should work:
In your Drawing_View class, add:
public void setPaintColor (String color) {
paint.setColor(Color.parseColor(color));
}
In your onClickListener, call the setPaintColor method:
drawingView.setPaintColor(color);
I assume that your Drawing_View is already instantiated.
Update
You need to instantiate your Drawing_View the same way you instantiated the Buttons in your activity's onCreate method.
public class Drawing_Main extends ActionBarActivity {
...
Drawing_View drawingView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_emoji_creation);
drawingView = (Drawing_View)findViewById(R.id.drawing_view);
green_light = (Button)findViewById(R.id.button1);
...
I hope this helps.
I want to disable my Seekbar and buttons with a switch which is Powerswitch
Here is a code snippet:
seekBar1.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
String sval = String.valueOf(i);
speakerVal.setText(sval);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
// button - Favorite Channel ABC
cabc = (Button) findViewById(R.id.buttonABC);
cabc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Set Favorite
curChannel.setText("007");
}
});
and here is my switch code:
final Switch switch1 = (Switch) findViewById(R.id.switch1);
switch1.setOnCheckedChangeListener(this);
more switch code:
public void onSwitchClicked(View view) {
final TextView PowerSwitch = (TextView) findViewById(R.id.PwrSwitchVal);
Switch sw = (Switch) view;
if (sw.isChecked()) {
PowerSwitch.setText("ON");
pwr = true;
} else {
PowerSwitch.setText("OFF");
pwr = false;
}
}
I know I can use the switch.isChecked(), but when I change the seekba1.setEnabled(false), I can't seem to get it to turn back on.
I haven't even tried to disable the buttons yet.
any help would be appreciated.
In your onSwitchClicked method, you should be calling seekbar.setEnabled in the if checked if-else statement. If checked seekbar.setEnabled(true) else seekbar.setEnabled(false)
try this.
switch1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton arg0,
boolean arg1) {
if (arg1) {
seekbar1.setEnabled(true);
}
else{
seekbar1.setEnabled(false);
}
}
});

If you want to convert Editable to simple text line (String), use this in your method:
#Override
public void afterTextChanged(Editable s) {
String str = s.toString();
}
When I swipe between questions, it loads current page number correctly
BUT when I use next button, first click doesnt loads pagenumber ( I mean onPageSelected() doesnt work.) second and other clicks loads content but it loads 1 page previous.
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.activity_main);
mPager = (ViewPager)findViewById(R.id.pager);
QuestionPagerAdapter mAdapter = new QuestionPagerAdapter();
mPager.setAdapter(mAdapter);
OnPageChangeListener pageChangeListener = new OnPageChangeListener() {
#Override
public void onPageScrollStateChanged(int arg0) { }
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) { }
#Override
public void onPageSelected(int position) {
tv.setText( mPager.getCurrentItem()+"");
}
};
mPager.setOnPageChangeListener(pageChangeListener);
Question.next.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
mPager.setCurrentItem(getItem(+1));
}
}
private int getItem(int i) {
int a = mPager.getCurrentItem();
i += a;
return i;
}
});
Why not just doing this in your listener:
mPager.setCurrentItem(mPager.getCurrentItem() + 1);
