一个超轻量级，简单好用的多文件选择器。

JTFilePicker

功能：

1. 支持自定义文件图标
2. 以字符串集合返回
3. 超级轻量，超级简单
4. 基于kotlin

安装：

首先在你的项目配置kotlin环境, 在你的moudle里添加如下代码：

dependencies {
    ......
    implementation 'com.william:JTFilePicker:1.3.2'
}

用法：

Kotlin(推荐):

/**
* kotlin启动
* @param 参数1：可以是activity或者fragment
*/
JTFilePicker.from(activity||fragment, object :OnFileIconLoadListener{
    override fun fileIconLoad(imageView: ImageView, fileBean: FileBean) {
        when (fileBean.extension) {
            "txt" ->
                //可以用普通方式设置drawable
                imageView.setImageDrawable(R.drawable.txt)
            "jpg"->//图片类型可以直接在图标中预览
                //推荐完全交给Glide或者其他图片加载框架
                Glide.with(context).load(fileBean.path).into(imageView)
        }
    }
})
//可选，设置首页路径（即能打开的根目录）默认为内存卡根目录
//.setRoot(Environment.getExternalStorageDirectory().path)
.open(0)

/**
* kotlin接收
*/
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    if (resultCode == Activity.RESULT_OK){
        Toast.makeText(this,"已成功：${data!!.getStringArrayListExtra("paths")}",Toast.LENGTH_SHORT).show()
    } else {
        Toast.makeText(this,"已取消",Toast.LENGTH_SHORT).show()
    }
}

java:

/**
* java 启动
* @param 参数1：可以是activity或者fragment
*/
JTFilePicker.Companion.from(this, new OnFileIconLoadListener() {
    @Override
    public void fileIconLoad(ImageView imageView, FileBean fileBean) {
        switch (fileBean.getExtension()) {
            case "txt":
                //可以用普通方式设置drawable
                imageView.setImageDrawable(R.drawable.txt);
                break;
            case "jpg"://图片类型可以直接在图标中预览
                //推荐完全交给Glide或者其他图片加载框架
                Glide.with(context).load(fileBean.getPath()).into(imageView);
                break;
                default:
        }

    }
})
//可选，设置首页路径（即能打开的根目录）默认为内存卡根目录
//.setRoot(Environment.getExternalStorageDirectory().path)
.open(0);

/**
* java java接收
*/
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == Activity.RESULT_CANCELED) {
        return;
    }
    switch (requestCode) {
        case REQUEST_PICK_FILE://从选择文件页面返回
            List<String> paths = data.getStringArrayListExtra("paths");
        break;
        default:
    }
}
