}

2. 调用

• 显示提示消息的对话框(仅提示)
  AlertDialogUtil.warningDialog(activity,activity.getString(R.string.SocketTimeoutException),activity.getString(R.string.SocketTimeoutException_des));
• 弹出对话框并有3个按钮可选择处理

final String[] reasons = new String[]{SUPPLEMENT_REASON_CUT_PARTS,SUPPLEMENT_REASON_THREAD,SUPPLEMENT_REASON_ACCESSORIES};
AlertDialogUtil.ThreeChoiceDialog(activity, "please select the reason of noLoad", "",reasons, new AlertDialogUtil.ThreeChoiceHandle() {
                            @Override
                            public void onPositiveButtonHandle() {
                                ToastUtil.show(activity,reasons[0]);
                            }

                            @Override
                            public void onNegativeButtonHandle() {
                                ToastUtil.show(activity,reasons[1]);
                            }

                            @Override
                            public void onNeutralButtonButtonHandle() {
                                ToastUtil.show(activity,reasons[2]);
                            }
                        });

3. 其他

• R.drawable.ic_comfirm资源文件

• 常量管理GlobalConstant类

package com.jack.feiYan2.tool;

import android.os.Environment;

import java.io.File;

/**
 * Created by liy on 2018-03-29.
 */

public class GlobalConstant {
    public static GlobalConstant globalConstant;

    public GlobalConstant(){

    }
    public static GlobalConstant getGlobalConstant(){
        if(globalConstant==null){
            globalConstant = new GlobalConstant();
        }
        return globalConstant;
    }

    public static final String SUPPLEMENT_REASON_CUT_PARTS = "Cut Parts";
    public static final String SUPPLEMENT_REASON_THREAD = "Thread";
    public static final String SUPPLEMENT_REASON_ACCESSORIES = "Accessories";

}
