以下是我在基础课上所做的工作。你需要让它充满活力:
public class SegmentedSeekBar extends android.support.v7.widget.AppCompatSeekBar {
private Paint progressPaint;
public SegmentedSeekBar(Context context) {
super(context);
init();
}
public SegmentedSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public SegmentedSeekBar(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}
private void init() {
progressPaint = new Paint();
progressPaint.setStyle(Paint.Style.FILL_AND_STROKE);
progressPaint.setColor(Color.LTGRAY);
progressPaint.setStrokeWidth(2.0f);
}
@Override
protected synchronized void onDraw(Canvas canvas) {
int halfHeight = getHeight() / 2;
int pos;
float smallH = 10;
float div = (getWidth() - getPaddingRight() - getPaddingLeft()) / (getMax());
for (int i = 1; i < getMax(); i++) {
pos = (int) (div * i) + getPaddingLeft();
canvas.drawLine(
pos + 1.0f,
halfHeight - (halfHeight / 2.0f),
pos + 1.0f,
halfHeight + (halfHeight / 2.0f),
progressPaint);
}
super.onDraw(canvas);
}
}

完成您的要求的最佳方法是在搜索栏上添加空视图(3 View)。使用match_parent高度创建视图,在搜索栏上创建2dp宽度。
