下边是相关代码，我又新建了两个新的，把代码复制过去还是不行
WxShareMenu.java

package org.pointstone.cugapp.view;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.animation.Animation;

import org.pointstone.cugapp.R;

import razerdp.basepopup.BasePopupWindow;

/**

 */

public class WxShareMenu extends BasePopupWindow implements View.OnClickListener {
    private View popupView;

    public WxShareMenu(Activity context) {
        super(context);
        bindEvent();
    }

    @Override
    protected Animation initShowAnimation() {
        return getTranslateAnimation(250 * 2, 0, 300);
    }

    @Override
    public View getClickToDismissView() {
        return popupView.findViewById(R.id.click_to_dismiss);
    }

    @Override
    public View onCreatePopupView() {
        popupView = LayoutInflater.from(getContext()).inflate(R.layout.wx_share_menu, null);
        return popupView;
    }

    @Override
    public View initAnimaView() {
        return popupView.findViewById(R.id.popup_anima);
    }

    private void bindEvent() {
        if (popupView != null) {
            popupView.findViewById(R.id.tx_1).setOnClickListener(this);
            popupView.findViewById(R.id.tx_2).setOnClickListener(this);
            popupView.findViewById(R.id.tx_3).setOnClickListener(this);
        }

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.tx_1:

                break;
            case R.id.tx_2:

                break;
            case R.id.tx_3:

                break;
            default:
                break;
        }

    }
}

Answer 2

其实我觉得,你clear下项目一般都会好,你的Popupwindow又不是一般的写在xml中需要完整包名,我没发现你的写法有问题,倒是Android Studio经常不把你写的代码打包到apk中,开发中经常遇到,一半Clear 或 Restart(Pc/Android Studio)可解决.

这个错误一般是由于运行环境找不到类或者定义的类创建失败所造成，一般控件中出现这个错误可能是由于该控件中某些所需的资源无法找到的原因，如attrs.xml,drawables等等，所以你需要确认你导入的引用的library的完整性，是仅仅只是依赖了一个jar还是一个aar(一个完整的andorid工程库)，若只是依赖jar的话，可能需要重新修改下依赖.
