Create the progress_bar.xml. You can define progress and background colors.
<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@android:id/background"> <shape> <solid android:color="#FF0000" /> </shape> </item> <item android:id="@android:id/progress"> <clip> <shape> <solid android:color="#00FF00" /> </shape> </clip> </item> </layer-list>
In the Activity,
SeekBar mSeekBar = (SeekBar) findViewById(R.id.seekBar1); mSeekBar.setProgressDrawable(getResources() .getDrawable(R.drawable.progressbar));
You can set the minHeight and maxHeight to make the progress bar thinner.
<SeekBar android:id="@+id/seekBar1" android:layout_width="match_parent" android:layout_height="wrap_content" android:minHeight="3dip" android:maxHeight="3dip" android:layout_margin="20dip"/>
