</LinearLayout>

2. Call

(1) Activity class

public class PublishToShangguanActivity extends BaseActivity implements CustomPopListener {

    //是否原创选择模块
    @InjectView(id = R.id.ly_is_original,click = true)
    private LinearLayout mLyOriginal;

    //选择是否原创弹窗
    CustomBottomPop originalSelectPop;
    protected List<PopBean> originalLists = new ArrayList<>();
    String[] originals = new String[]{"是","否"};

    @Override
    public void onPreInject() {
        Utils.fitSystemWhite(this);
        setContentView(R.layout.activity_publish_to_shangguan);
    }

    @Override
    protected void onPostCreate() {
    }


    //重点关注监听这里，其余根据业务可变
    @Override
    public void onClick(View v) {
        if (v == mLyOriginal){
            //调出选择是否原创弹窗
            originalLists.clear();
            for (int i = 0;i < originals.length;i++){
                originalLists.add(new PopBean(i,originals[i]));
            }
            originalSelectPop = new CustomBottomPop(this, originalLists, this);
            originalSelectPop.setClippingEnabled(true);
            originalSelectPop.showAtLocation(getRootView(), Gravity.CENTER, 0, 0);
        }
    }

    //弹窗选择监听，可取出选择项的值
    @Override
    public void onClickButton(CustomBottomPop customBottomPop, PopBean bean) {
       if (customBottomPop == originalSelectPop){
            mTvOriginal.setText(bean.getValue());
        }
        customBottomPop.dismiss();
    }
}

(2) Custom listening class CustomPopListener.java

package com.custom.jfrb.ui.first.base;

import com.custom.jfrb.ui.first.bean.PopBean;
import com.custom.jfrb.ui.first.customView.CustomBottomPop;

/**
 * Created by Administrator on 2018/3/1 0001.
 */

public interface CustomPopListener{
    void onClickButton(CustomBottomPop customBottomPop, PopBean bean);
}

3. Done, Nice!
