2 使用

Step 1. 添加 JitPack 仓库

在项目的 build.gradle 添加 JitPack 仓库

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Step 2. 添加依赖

在需要使用的 module 中添加依赖

dependencies {
    compile 'com.github.wildma:IDCardCamera:1.0.1'
}

或者引用本地 lib

compile project(':idcardcamera')

Step 3. 调用 CameraActivity 类的 toCameraActivity 方法打开拍照界面

CameraActivity.toCameraActivity(this, CameraActivity.TYPE_IDCARD_FRONT);

Step 4. 在 onActivityResult 方法中获取裁剪后的图片

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == CameraActivity.REQUEST_CODE && resultCode == CameraActivity.RESULT_CODE) {
            //获取图片路径，显示图片
            final String path = CameraActivity.getImagePath(data);
            if (!TextUtils.isEmpty(path)) {
                imageView.setImageBitmap(BitmapFactory.decodeFile(path));
            }
        }
    }
