由 孤街醉人 提交于 2019-12-04 01:04:23
问题 This question already has answers here : Android SeekBar set progress value (6 answers) Closed last year . I am using a Seekbar in a fragment and need to move the Seekbar to different positions. However, setProgress(xxx) is not working. How do you trigger this method programmatically for a Seekbar : public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) ? Moving the Seekbar manually works fine. 回答1: It's a Bug in ProgressBar! The setProgress(...) seems to not trigger

Android Seekbar float values from 0.0 to 2.0

由 心已入冬 提交于 2019-12-03 17:39:28
问题 how can I get the values ​​from 0.0 to 2.0 with a seekbar ? values ​​should go in steps of 0.5 ( 0.0 , 0.5 , 1.0, 1.5, 2.0) can someone help me? 回答1: SeekBar extends ProgressBar. ProgressBar has a method public void setMax(int max) Since it only accepts int you'll have to do some conversion from an int value to get the float that you are after. Something like this should do the trick: mSeekBar.setMax(4); //max = 4 so the possible values are 0,1,2,3,4 seekbar.setOnSeekBarChangeListener( new

Espresso - Set SeekBar

问题 does anybody know, how to set a seekBar to a specific value or just a click on that view on Espresso UI Testing ? I just get an exception: Error performing 'single click' on view with id... onView(withId(R.id.FilterPriceMax)).perform(click()); 回答1: I use a swipe-action to perform an actual swipe on the SeekBar . This makes sure the callback method ( SeekBar.OnSeekBarChangeListener. onProgressChanged ) is called with fromUser set to true. It is also more in the line of click testing. public

Detecting thumb position in SeekBar prior to API version 16

由 蓝咒 提交于 2019-12-03 16:16:40
问题 Basically, I need to detect when the progress changes in the SeekBar and draw a text view on top of the thumb indicating the progress value. I do this by implementing a OnSeekBarChangeListener and on the public void onProgressChanged(SeekBar seekBar, int progress, boolean b) method, I call Rect thumbRect = seekBar.getThumb().getBounds(); to determine where the thumb is positioned. This works perfectly fine, but apparently getThumb() is only available in API level 16+ (Android 4.1), causing a
