Android SeekBar set progress value

断了今生、忘了曾经 提交于 2019-11-28 00:42:40
I want the SeekBar progress to change whenever I click a button. Using setProgress() works only for initial value. It throws an error if I use it after some changes. Perhaps you should try to use a handler? I use this in an app of mine and works fine. 1) When creating your SeekBar: // ... seekBarHandler = new Handler(); // must be created in the same thread that created the SeekBar seekBar = (SeekBar) findViewById(R.id.my_seekbar); // you should define max in xml, but if you need to do this by code, you must set max as 0 and then your desired value. this is because a bug in SeekBar (issue

I have a SeekBar that will change the progress when I require it to, but I don't want the user to be able to change it manually. I tried to set the SeekBar as this: <SeekBar android:id="@+id/seekBar1" android:layout_width="match_parent" android:layout_height="65dp" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="78dp" android:progress="10" android:max="100" android:clickable="false" android:thumb="@drawable/transparent" android:progressDrawable="@drawable/customprogressbar" /> But it doesn't work. How can I do this? That's more or less an

Android SeekBar Flipped Horizontally

问题 With the Android SeekBar, you can normally drag the thumb to the left or to the right and the yellow progress color is to the left of the thumb. I want the exact opposite, essentially flipping the yellow progress color to the right of the thumb and flipping the entire SeekBar on the y-axis. Can anyone point me in the right direction? Thanks! 回答1: After fiddling around with some code this is what I got and it seems to work pretty well. Hopefully it will help someone else in the future. public

Android SeekBar setOnSeekBarChangeListener

拟墨画扇 提交于 2019-11-27 21:50:16
I'm wondering about the behavior of the android SeekBars OnSeekBarChangeListener. In particular, is the onProgressChanged-method notified only for the first and the last touch on the seekbar? I'm trying to refresh a TextView that should show the current progress of the SeekBar. But the TextView is just updated on first touch and last touch. Debugging this confirms my assumption that this method is called just twice :( What I would like to have is that the TextView shows every progress change in the SeekBar. In short: I am searching for a possibility to get a progress listener that is called

I want to make customer seek bar like this image: i checked this and this . if anyone have any idea about this..please share it.Thank you If I understand correctly you want to create a number value above the actual slider that moves along the orb. One thing you can do is write a text above the actual image of the slider by "merging" the text directly onto the drawable file of the orb image. I am assuming you are using the first tutorial you provided in your original question public class CustomSeekBar extends Activity { SeekBar mybar; @Override public void onCreate(Bundle savedInstanceState) {

How to Set an Android SeekBar to be unmoveable/frozen?

问题 In my XML, I've set the focusable , focusableInTouchMode , clickable , and longClickable variables to false, yet I can still click and move the SeekBar. Do I need to actually change the listener events to do this? That seems so unnecessary. 回答1: mySeekBar.setEnabled(false); or for XML: android:enabled="false" 回答2: You could create a subclass whose parent is a SeekBar . In your new class, override the onTouchEvent() method to always return false. This solution should not "grey out" the seek
