seekbar

问题 I have prepared a simple test project for my question at GitHub. In my project there is a custom inline SeekBarPreference, which mostly works fine (its summary is updated when seekbar is being dragged and it saves integer value): However there is a problem: On the very 1st run of the app (you might need to uninstall my app when you try see the error again) the progress of the SeekBar is not set (but the summaries are set): My question is: how to fix this issue in my code? I have tried adding

I am not being able to figure out, how to implement this along with the android SeekBar , as there doesn't seem to be any option available for

问题 I would like to use a dialog with a seekbar in my application. But I don't really know how to do it because I lack experience with android. So, when you press a button: a dialog should come up, with a seekbar and the user is able to enter a value and then press OK-button.

问题 I'd like to set max and minimum limits of SeekBar to 50 and 20 respectively. SeekBar has a direct option top provide max value, but how to set its minimum value to 20 rather than 0? 回答1: In SeekBar you can set only max value. <SeekBar android:id="@+id/SeekBar01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:max="50"/> And, You cannot directly set the minimum value to the seekbar. SeekBar mSeekbar = (SeekBar) findViewById(R.id.SeekBar01); mSeekbar
