+**XMl文件**
+```
+    <com.zyf.ruler.rulerlibrary.WeightChoiceView
+        android:id="@+id/height"
+        app:arc="false"
+        android:layout_width="match_parent"
+        android:layout_height="wrap_content"
+        app:max="300"
+        app:min="100"
+        app:mSelectorValue="250"/>
+```
+
+**代码文件**
+```
+  WeightChoiceView weight = findViewById(R.id.weight);
+  weightValue = findViewById(R.id.weight_value);
+  weight.setListener(new WeightChoiceView.OnValueChangeListener() {
+      @Override
+      public void onValueChange(float value) {
+          weightValue.setText("体重："+value+"Kg");
+      }
+  });
+```
+
+也可以在代码中设置最大值，最小值和选中的值
+
+```
+  WeightChoiceView weight = findViewById(R.id.weight);
+  weight.setValue(250,300,100,1.0f);
+```
+
+最后面的数据是刻度间隔1.0表示间隔1,0.1表示间隔为0.1 
+
+
+| 名称        | 值   | 
+| :--------:   | :-----:  | 
+| 刻度颜色 | mBgPaintColor | 
+| 默认字体颜色 | mTextPaintColor | 
+| 默认字体大小 | mTextSize | 
+| 选中字体大小 | mTextSelectSize | 
+| 选中字体颜色 | mTextSelectColor | 
+| 最小值 | min | 
+| 最大值 | max | 
+| 刻度间距 | spacing | 
+| 是否弧度尺 | arc |  
+| 选中刻度 | mSelectorValue |  
+
+选中刻度只能在最大值和最小值之间，否则刻度不绘制。
+
+
+**因为自己项目用到的是弧度尺，看到[RuleView](https://github.com/panacena/RuleView)实现直尺思路**
