seekbar

问题 I'm not tied to using an ArrayAdapter but, what I want is a list where each item contains an ImageView, a TextView, and a SeekBar to where I can update the images/texts as well as receive callbacks from each slider (obviously, I need to be able to add and delete rows dynamically). I've no trouble creating a list that contains these items that is static -> i.e. defined in an xml layout for each row of my list.

问题 I have tried this and this for Design Custom Seekbar for ExoPlayer but no luck. I want to design custom thumb and ProgressBar for ExoPlayer. Following is the XML for ExoPlayer where I've tried to put seekbar but it's not coming as expected. <com.google.android.exoplayer.AspectRatioFrameLayout android:id="@+id/video_frame" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity="center"> <SurfaceView android:id="@+id/surface_view" android:layout_width=

问题 I need to paint an overlay image onto a SeekBar in my ListView rows. This isn't too hard to do and the code in this question accomplishes that by painting the row number in a bitmap and placing it as the progress drawable. The problem that I am having is that this only works one time. When the view is recycled to be used for another row, the drawable disappears. The first 10 views (positions 0 through 9) worked. Everything after that fails. There is no error or exception. Android just stops

问题 I'm trying to add a seekbar item to my options menu, but all I get is a panel with my title for the text.

问题 I want to create a seekbar like in this image: seekbar http://i47.tinypic.com/k2k54z.jpg The question is, how to place thumb above the progress line?
