Hi Stoyan, Yesterday I also asked myself if there's a Seekbar preference but I looked around and did not find any so I created my own. Here's my code if it will help you.
public class SeekBarPreference extends DialogPreference{ private Context context; private SeekBar volumeLevel; public SeekBarPreference(Context context, AttributeSet attrs) { super(context, attrs); this.context = context; } protected void onPrepareDialogBuilder(Builder builder) { LinearLayout layout = new LinearLayout(context); layout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT)); layout.setMinimumWidth(400); layout.setPadding(20, 20, 20, 20); volumeLevel = new SeekBar(context); volumeLevel.setMax(8); volumeLevel.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); volumeLevel.setProgress(0); *// You might want to fetch the value here from sharedpreferences* layout.addView(volumeLevel); builder.setView(layout); super.onPrepareDialogBuilder(builder); } protected void onDialogClosed(boolean positiveResult) { if(positiveResult){ persistString(volumeLevel.getProgress()+""); } } } then in your activity you can use this class: SeekBarPreference sb = new SeekBarPreference(this, null); sb.setTitle(R.string.volume); sb.setSummary(R.string.volume_summary); sb.setKey(VOLUME_LEVEL_PREF); -Marc On Fri, Jan 9, 2009 at 9:13 AM, Stoyan Damov <stoyan.da...@gmail.com> wrote: > > Hi guys, > > The emulator and G1's Settings apps apparently launches a preference > activity. > In Settings, Sound and Display, when you touch the "Ringer volume" > setting, a dialog pops up, which shows a SeekBar. > My question is how is this implemented because I need a similar (seek > bar-driven) setting in my app. > > I don't have Android's source code and am hesitant to download 2.1G > just to check :( > I'm guess this setting does NOT launch an intent which pops up the > dialog (because I'd expect that intent to be wrapped in > PreferenceScreen and then I'd see the circled arrow indicator) but > can't be sure. > I know many people on the list are Google employees and am hoping I'll > get an answer. > > Thanks in advance, > Stoyan > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
