# AiYaScanner
:fire: zxing and zbar combined with scan code. 只为真正的 zxing zbar 结合二维码扫描：https://github.com/nanchen2251/AiYaScanner
TODO：
1. 剥离 zxing（已完成）；
2. 优化 zxing 预览和解码（已完成）；
3. 加入 zbar 解码（已完成）；
4. 兼容优化；（部分完成）；
5. 二维码放大缩小(已完成)；
6. 目前解码为了兼容，是串行的，相反拖长了时间，后面会改成并行的。
7. 自动放缩；
8. 目前为了速度，**仅支持二维码**，后面暴露接口支持其他格式；
**更多有效的优化，请大家一起来提 PR！**
**有任何需求或者 BUG,请提 issues！**
## 效果图<br>
#### ⊙开源不易，希望给个 star 或者 fork 奖励
#### ⊙拥抱开源：https://github.com/nanchen2251/
#### ⊙交流群（拒绝无脑问）：118116509 <a target="_blank" href="//shang.qq.com/wpa/qunwpa?idkey=e6ad4af66393684e1d0c9441403b049d2d5670ec0ce9f72150e694cbb7c16b0a"><img border="0" src="http://pub.idqqimg.com/wpa/images/group.png" alt="Android神技侧漏交流群" title="Android神技侧漏交流群"></a>( 点击图标即可加入 )<br>
## 特点
1、只为极速扫码而生。<br>
2、默认只支持二维码扫描。<br>
3、支持双击放大缩小。<br>
4、支持多指放大缩小。<br>
## 使用方法
#### 1、添加依赖<br>
##### Step 1. Add it in your root build.gradle at the end of repositories:
```java
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
```
##### Step 2. Add the dependency
```java
dependencies {
implementation 'com.github.nanchen2251:AiYaScanner:1.0.7'
}
```
#### 2、在Activity里面使用<br>
```java
// 必须自己先申请相机和存储权限
CaptureActivity.startForResult(MainActivity.this, 1024);
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == 1024 && data != null) {
String result = data.getStringExtra("result");
Toast.makeText(getApplicationContext(), "扫码结果：" + result, Toast.LENGTH_SHORT).show();
}
}
```
#### 3、你也可以自己编写你的扫一扫 UI
```
// Activity 请继承于 BaseCaptureActivity
// 你也可以不继承，但记得编写相关方法
```
