dependencies { 44 | compile 'com.mengfei:AddSubUtils:1.5.0' // 最新版本 45 | } 46 | ``` 47 | 或者下载源码包，链接：https://github.com/Jmengfei/AddSubUtils ，引用本地lib,并且在build.gradle中添加： 48 | ``` 49 | dependencies { 50 | compile project(':addsubutils') 51 | } 52 | ``` 53 | 54 | ### 2. 在xml代码中引用 55 | 56 | ``` 57 | 61 | ``` 62 | 你也可以自定义样式： 63 | 64 | ``` 65 | 80 | ``` 81 | 82 | ### 3.在Activity或者Fragment中配置AddSubUtils 83 | 84 | ``` 85 | AddSubUtils addSubUtils = (AddSubUtils) findViewById(R.id.add_sub); 86 | addSubUtils.setBuyMax(30) // 最大购买数，默认为int的最大值 87 | .setInventory(50) // 库存，默认为int的最大值 88 | .setCurrentNumber(5) // 设置当前数，默认为1 89 | .setStep(5) // 步长，默认为1 90 | .setBuyMin(2) // 购买的最小值，默认为1 91 | .setOnWarnListener(new AddSubUtils.OnWarnListener() { 92 | @Override 93 | public void onWarningForInventory(int inventory) { 94 | Toast.makeText(MainActivity.this, "当前库存:" + inventory, Toast.LENGTH_SHORT).show(); 95 | } 96 | 97 | @Override 98 | public void onWarningForBuyMax(int max) { 99 | Toast.makeText(MainActivity.this, "超过最大购买数:" + max, Toast.LENGTH_SHORT).show(); 100 | } 101 | 102 | @Override 103 | public void onWarningForBuyMin(int min) { 104 | Toast.makeText(MainActivity.this, "低于最小购买数:" + min, Toast.LENGTH_SHORT).show(); 105 | } 106 | }); 107 | ``` 108 | 109 | ### 4. 如果你是在ListView或者RecyclerView中使用： 110 | 111 | ``` 112 | holder.list_item_utils 113 | .setStep(1) 114 | .setBuyMax(30) 115 | .setPosition(position) // 传入当前位置，一定要传，不然数据会错乱 116 | .setCurrentNumber(dataBean.getValue()) 117 | .setInventory(50) 118 | .setOnWarnListener(new AddSubUtils.OnWarnListener() { 119 | @Override 120 | public void onWarningForInventory(int inventory) { 121 | Toast.makeText(ListViewActivity.this, "不能超过当前库存:" + inventory, Toast.LENGTH_SHORT).show(); 122 | } 123 | 124 | @Override 125 | public void onWarningForBuyMax(int max) { 126 | Toast.makeText(ListViewActivity.this, "超过最大购买数:" + max, Toast.LENGTH_SHORT).show(); 127 | } 128 | 129 | @Override 130 | public void onWarningForBuyMin(int min) { 131 | Toast.makeText(ListViewActivity.this, "低于最小购买数:" + min, Toast.LENGTH_SHORT).show(); 132 | } 133 | }) 134 | .setOnChangeValueListener(new AddSubUtils.OnChangeValueListener() { 135 | @Override 136 | public void onChangeValue(int value,int position) { 137 | setValue(position,value); // 使用传回来的position设置数据 138 | } 139 | }); 140 | ``` 141 | 注意：这里setPosition()是一定要有的 142 | 143 | 采用的是链式调用，这里你只需要传入你关心的值即可。 144 | 145 | # 关于我 146 | 147 | 一个想搞事情的Android攻城狮 148 | 149 |
