Toast
implementation 'com.github.GrenderG:Toasty:1.5.0'
Webdav
//需要替换okhttp3版本，以去除kotlin库
implementation('com.thegrizzlylabs.sardine-android:sardine-android:0.5'){

ListView

基于该代码封装了一个helper类，实现一个简单的列表单选对话框功能

import com.zhy.adapter.recyclerview.base.ViewHolder;
import java.lang.ref.WeakReference;
import java.util.List;
public class ListViewHelper<T> {
public static final String TAG = "ListViewHelper";

return this;
}
public ListViewHelper callback(Callback<T> callback) {

return this;
}
public void show() {

}
public String getTitle(T item){

调用例子
ListViewHelper listViewHelper= new ListViewHelper<BluetoothBean>(getActivity(),"选择设备"){

@Override
public String getTitle(BluetoothBean item) {

return item.mac;
}
return String.format("%s(%s)",item.mac,item.name);
}
};
listViewHelper.watch(beans).callback((ListViewHelper.Callback<BluetoothBean>) item -> {
if(getPreferenceManager().getSharedPreferences().edit().putString(prefHexUpload,ByteUtil.toHexString(item.raw)).commit()){
ToastHelper.success("已采集选择的设备数据");

}).show();
