how to

layout files

 <com.cn.naive.lib.view.BezierCurveChart
    android:id="@+id/bezier_curve_chart"
    android:layout_width="match_parent"
    android:layout_height="260dp"
    android:layout_margin="10dp" />

Java code

List<BezierCurveChart.Point> points=new ArrayList<BezierCurveChart.Point>();
for(int i=0;i<10;i++) {
	points.add(new Point(i, (float) (Math.random()*10)));
}
String tipText = "3 hours/day on average";
		
BezierCurveChart bezierCurveChart = 
	(BezierCurveChart) rootView.findViewById(R.id.bezier_curve_chart);
bezierCurveChart.init(points, 
	new String[] { "0:00", "6:00", "12:00", "18:00", "24:00" }, tipText);

If you don't want to show the tips on the middle of the chart, set the last parameter of bezierCurveChart.init to null.

bezierCurveChart.init(points, 
	new String[] { "0:00", "6:00", "12:00", "18:00", "24:00" }, null);

布局文件

 <com.cn.naive.lib.view.BezierCurveChart
    android:id="@+id/bezier_curve_chart"
    android:layout_width="match_parent"
    android:layout_height="260dp"
    android:layout_margin="10dp" />

Java代码

List<BezierCurveChart.Point> points=new ArrayList<BezierCurveChart.Point>();
for(int i=0;i<10;i++) {
	points.add(new Point(i, (float) (Math.random()*10)));
}
String tipText = "3 hours/day on average";		
BezierCurveChart bezierCurveChart = 
	(BezierCurveChart) rootView.findViewById(R.id.bezier_curve_chart);
bezierCurveChart.init(points, 
	new String[] { "0:00", "6:00", "12:00", "18:00", "24:00" }, tipText);

如果不需要中间的提示条，将bezierCurveChart.init最后一个参数设置为null即可，代码如下

bezierCurveChart.init(points, 
	new String[] { "0:00", "6:00", "12:00", "18:00", "24:00" }, null);
