| ``` 18 | compile 'com.zkk.view:ZkkRulerView:1.0.0' 19 | ``` 20 | ######2.2 在xml中设置 21 | 22 | ``` 23 | 41 | ``` 42 | ######2.3 在activity中只需调用一个方法和一个数值的回调 43 | ``` 44 | ruler_height=(RulerView)findViewById(R.id.ruler_height); 45 | ruler_weight.setOnValueChangeListener(new RulerView.OnValueChangeListener() { 46 | @Override 47 | public void onValueChange(float value) { 48 | tv_register_info_weight_value.setText(value+""); 49 | } 50 | }); 51 | 52 | /** 53 | * 54 | * @param selectorValue 未选择时 默认的值 滑动后表示当前中间指针正在指着的值 55 | * @param minValue 最大数值 56 | * @param maxValue 最小的数值 57 | * @param per 最小单位 如 1:表示 每2条刻度差为1. 0.1:表示 每2条刻度差为0.1 在demo中 身高mPerValue为1 体重mPerValue 为0.1 58 | */ 59 | ruler_weight.setValue(165, 80, 250, 1); 60 | ``` 61 | 62 | *** 63 | ##### 3、实现讲解 64 |
