Android: Make custom seekbar opaque - android-seekbar

Question

Hi can anyone tell me why is my Seekbar's background and progress always have some opacity and just can't be removed even I have set the alpha to 1.0. Below is my progress_drawable.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape>
<corners android:radius="5dip" />
<gradient
android:alpha="1.0"
android:startColor="#000000"
android:endColor="#000000"/>
</shape>
</item>
<item android:id="#android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient
android:alpha="1.0"
android:startColor="#000000"
android:endColor="#000000" />
</shape>
</clip>
</item>
<item android:id="#android:id/progress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient
android:alpha="1.0"
android:endColor="#2e2dff"
android:startColor="#2e2dff" />
<solid android:color="#2e2dff" />
</shape>
</clip>
</item>
And this is the SeekBar tag in activity xml:
<SeekBar
android:padding="0dp"
android:id="#+id/normalSeekbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/imgPenguin"
android:alpha="1"
android:progress="0"
android:progressDrawable="#drawable/progress_drawable"
android:secondaryProgress="0" />
I got this result but I want the bars to be opaque, please advise and thanks in advanced.

Just found the issue:
normalSB.setEnabled(false);
I shouldn't use setEnabled(false) to avoid user drag on thumb, instead, I have done this to reset progress when fromUser == true:
normalSB.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
int originalProgress;
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
float seekBarStarting = seekBar.getX();
float seekBarWidth = seekBar.getWidth();
float seekBarOffset = seekBar.getThumbOffset();
float ratio = (float) progress / seekBar.getMax();
float scaledProgress = ratio * seekBarWidth;
if (scaledProgress > imgPenguin.getWidth()) {
imgPenguin.setX(seekBarStarting - imgPenguin.getWidth() + scaledProgress);
}
if (fromUser == true) {
seekBar.setProgress(originalProgress);
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
originalProgress = seekBar.getProgress();
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
