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

其實我覺得,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)可解決.

這個錯誤一般是由於運行環境找不到類別或定義的類別建立失敗所造成，一般控制項中出現這個錯誤可能是由於該控制項中某些所需的資源無法找到的原因，如attrs.xml,drawables等等，所以你需要確認你導入的引用的library的完整性，是僅僅只是依賴了一個jar還是一個aar(一個完整的andorid工程庫)，若只是依賴jar的話，可能需要重新修改下依賴.
