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

Actually, I think you 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) can solve it.

Answer 3

This error is generally caused by the running environment not being able to find the class or the creation of the defined class failing. This error may occur in a general control because some required resources in the control cannot be found, such as attrs.xml, drawables Wait, so you need to confirm the integrity of the referenced library you imported, whether it only relies on a jar or an aar (a complete andorid project library). If you only rely on jar, you may need to modify the dependencies.
