Re: [android-developers] Seekbar Save state and restore
I think you mean save the position of the seekbar (eg users preference) then you can use shared prefs . this thus: onCreate reads the shared prefs and sets the value of the seekbar your 'save' function then writes the value to shared prefs.

[android-developers] SeekBar thumb colour problem when added through a handler
Hi, I have added a (default) seekbar dynamically to a linear layout in a handler class. The white colour of the thumb is not showing up. Could somebody let me know what is the problem?

[android-developers] seekbar to be more accurate
I'm using a seekbar to display and reposition at a frame in a video,
using:
private class frameChanger implements OnSeekBarChangeListener {
@Override public void onProgressChanged(SeekBar seekBar, int
progress, boolean fromUser) {
if (fromUser isVideo) {
Log.e(Frame Changer,Progress + progress);
video.seekTo(progress);
video.requestFocus();
video.invalidate();
}
}
I can move the seek bar just a tiny tiny amount and the value in the
log.e output changes by say 12 - 20
But the video does not change at all
However I can move the bar 1/2 inch which has resulted in a value change
of 300 - 500 and then the video changes.
By video changes I'm meaning the displayed frame of the video.
Obviously because the value jumped is so high the number of frames
skipped is huge. and very noticable.
If there anyway to update the the display and just move the one or two
frames when the values changes small amounts,
and NOT just move when the value change is large ?
Thanks in advance

[android-developers] Seekbar button separating from slider
Hi everyone - I'm using the seekbar for the first time within a RelativeLayout. When I try to reposition the bar using LayoutParams and setPadding the bar does move as expected but I also see the button moving apart from the progress slider. I'm unclear what is going on. Has anyone else seen this? Also I need a vertical seekbar. setRotation(90) seems to work but it is very hard to get the slider to move. Again I did not see any obvious way of creating a vertical seekbar. Any suggestions/insights would be welcome. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] SeekBar jumps ahead initially while playing short media files
Hi All,
I am implementing a media player with seekbar controls.
I am using AsyncTask to update the seekbar progress.
I am facing one issue with seekbar when media player plays short media
files( 15 sec duration).
The issue is that seekbar suddenly jumps to around 2 seconds forward
at the start and then it is normal after this jump.
I mean, the seekbar does not start at the far left. Instead, it seems
to jump ahead initially.
Below is the Asynctask code for this
@Override
protected String doInBackground(Context... params) {
while (mCurrentPosition mTotalDuration) {
try {
mCurrentPosition = mPlayer.getCurPosition();
if (mCurrentPosition 0) {
this.publishProgress(mTotalDuration);
} else {
this.publishProgress(mCurrentPosition);
}
Thread.sleep(20);
} catch (InterruptedException e) {
return null;
} catch (Exception e) {
return null;
}
if (this.isCancelled()) {
return null;
}
}
@Override
protected void onProgressUpdate(Integer... progress) {
mSeekbar.setProgress(progress[0]);
mDurationView.setText(ConvertToTimeString(progress[0]));
}
///
Could anybody give some pointers to resolve this issue.
Thanks,
Ganesh

[android-developers] SeekBar problem
Hello list.I would like to know why this code don't work:
seekTime.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
public void onStopTrackingTouch(SeekBar seekBar)
{
seekBar.setMax(seekBar.getProgress() * 2);
}
[...]
I'm sure that the function get called because i tried to set a breakpoint.
After the execution the mMax member value is correctly changed, the
mProgress don't change, but the graphical bar don't move as it should to
reflect the new value (it should go to the center).
I tried to add a
seekBar.invalidate();
but it don't help..

[android-developers] SeekBar bug or intended?
I made a SeekBar like below. SeekBar android:id=@+id/SeekBar011 android:layout_width=200px android:layout_height=80px android:progressDrawable=@drawable/ progress_horizontal2 android:thumb=@drawable/seek_thumb2 / All images in progress_horizontal2.xml seek_thumb2.xml have 64px height. I expected that progressBar thumbs are nicely vertically centered at (80-64)/2 px y-pos. (I put 80px at layout_height is for wider touch area) But what I saw is the progressbar a few pixel below the thumb. I looked into the AbsSeekBar.java and found that the default maxHeight value is 48px(why?) so progressbar moved down (64-48)/2 px in onSizeChanged(). I was surprised that the default maxHeight value is not Math.max (progressbar's height, thumb's height). Is there any reason for this or just a bug? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] seekbar / progressbar
i want to change the color of progressbar as the cursor is moved, but
setProgressDrawable() seems to work only within OnCreate() method, if
i change the ProgressDrawable inside onProgressChanged method
inspecting mSeekBar i can see that the value of Currentdrawable and
ProgressDrawable is updated but the progressbar disappear and it
reappears only when the progressdrawable changes back to the old value
(the one set in the onCreate method)
public void onProgressChanged(SeekBar seekBar, int progress,boolean
fromTouch) {
seekBar.setProgressDrawable(new_drawable);
}
Full code:
public class SeekBar2 extends Activity implements
SeekBar.OnSeekBarChangeListener {
SeekBar mSeekBar;
TextView mProgressText;
TextView mTrackingText;
static LayerDrawable mdrawable_green;
static LayerDrawable mdrawable_blue;
static LayerDrawable mdrawable_red;
enum BarColor {
RED, BLUE, GREEN;
LayerDrawable getDrawable(){
switch(this){
case RED: return mdrawable_red;
case BLUE: return mdrawable_blue;
case GREEN: return mdrawable_green;
default : return mdrawable_red;
}
}
};
BarColor mcolor;
public BarColor getColor() {
return mcolor;
}
public void setColor(SeekBar seekbar,BarColor color) {
this.mcolor = color;
seekbar.setProgressDrawable(color.getDrawable());
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mSeekBar = (SeekBar) findViewById(R.id.seek);

setColor(mSeekBar ,BarColor.RED);
mSeekBar.setOnSeekBarChangeListener(this);
mProgressText = (TextView) findViewById(R.id.progress);
mTrackingText = (TextView) findViewById(R.id.tracking);
}
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromTouch) {
mProgressText.setText(progress + + seekbar_from_touch
+ = + fromTouch);
BarColor color;
if(progress 33)
color = BarColor.RED;
else if ((progress=33) (progress66))
color = BarColor.BLUE;
else
color = BarColor.GREEN;
if(color!=mcolor)
setColor(seekBar,color);
}
public void onStartTrackingTouch(SeekBar seekBar) {
mTrackingText.setText(seekbar_tracking_on);

[android-developers] SeekBar
Hi, How to set the thumb position when progress has changed. -- Thank Regards Peeyush Varshney --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Seekbar thumb animation
Hi, As the seekbar thumb is a drawable so its support for animation seems limited. It may not be feasible but I would like to hear feedback from those who have more experience w/ UI. Animations I have in mind are quite simple like a few blinks when layout becomes visible. With Views, blinks can be easily implemented with alpha cycles but not so for Drawables. I explored several ideas but none seems to work well: * Using AnimationDrawable does not seem to help as it requires an ImageView host. * My main activity has an animation on its layout. I tried to set the thumb drawable to another bitmap onAnimationEnd when the main layout is complete. The old drawable went away but the new one did not show so the thumb disappeared. I checked the thumboffset to make sure it was not out of range. * Set a Drawable callback on the drawable but that also requires a view. Another way is to have a custom seekbar with a View for thumb instead of Drawable. Please let me know if I have overlooked any other options currently supported by SDK ?

[android-developers] Seekbar - Snap to value
Hey, Quick question... Is there a way to define set values (i.e. 0%, 25%, 50%, 75%, 100%) for the seekbar widget that enables the slider to snap to the nearest set value? For example instead of allowing the user to position the slider at an percentage through 0-100, instead the slider can only ever be positioned at one of the five set values? Oh and while were on the subject is there an easy solution for positioning the seekbar vertically, i'd rather not hack through the seekbar source code - but I fear I may have to!

[android-developers] SeekBar does not reach the end
Hello,
I have an options panel that allows setting of keyboard sensivity. I
use SeekBar to get the sensivity but it never reaches the max end.
There is the code:
final SeekBar seekBarKeyboardSens = (SeekBar)findViewById
(R.id.SeekBarKeyboardSens);
seekBarKeyboardSens.setMax(10);
seekBarKeyboardSens.setProgress(keyboardSensivity);
seekBarKeyboardSens.setOnSeekBarChangeListener(new
OnSeekBarChangeListener()
{
@Override
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2)
{
keyboardSensivity = arg1;
}
// other overrides
});
Max value I got is 8...
Has anyone solved that problem?
