The problem is that I am using custom progressDrawable in SeekBar widgets (maybe wrong), it displays on the form with very smooth / ugly / low quality. I set "drawingCacheQuality" to a high level and there is no difference. Does anyone have any ideas?
Developed on Nexus One (OS 2.2.1) with a target build for the project as API 1.5 (although I hope it doesn't matter).
Here is an example of what it looks like:
My goal is to create a simple excellent visual switch with two states (on and off) and a slider for moving between them. I really have not seen a better widget for this, and almost everything is done for me with SeekBar. If someone has a better idea that does not require rewriting a ton of code plate with a bowler, that would be nice. It seems like this really should be doable with minimal effort, somehow working with or expanding the SeekBar. I am at a loss where to start.
I guess one idea is to simply overlay my on_off image on a ShapeDrawable and use it as a background (and "@android: color / transparency" for progressDrawable), but I'm not too familiar with how to do this. ..
The base code for the new actvitiy
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
seek = (SeekBar)findViewById(R.id.seek);
seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromTouch) {
}
public void onStartTrackingTouch(SeekBar seekBar) {
}
public void onStopTrackingTouch(SeekBar seekBar) {
if (seek.getProgress() < seek.getMax() / 2.0)
seek.setProgress(0);
else
seek.setProgress(seek.getMax());
}
});
}
