問題描述

昨天好的，今天就不行了，下邊的代碼報錯

WxShareMenu popup = new WxShareMenu(AboutActivity.this);popup.showPopupWindow();

java.lang.NoClassDefFoundError: org.pointstone.cugapp.view.WxShareMenu at org.pointstone.cugapp.activities.AboutActivity$5.onClick(AboutActivity.java:188) at android.view.View.performClick(View.java) at android.view.View$PerformClick.run(View.java) at android.os.Handler.handleCallback(Handler.java) at android.os.Handler.dispatchMessage(Handler.java) at android.os.Looper.loop(Looper.java) at android.app.ActivityThread.main(ActivityThread.java) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java) at dalvik.system.NativeStart.main(Native Method)

下邊是相關代碼，我又新建了兩個新的，把代碼復制過去還是不行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;/** * Created by Administrator on 2017/3/2. */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;} }}

求解決，我要崩潰

問題解答

函數超過 65536 個了，http://www.jianshu.com/p/2450...

其實我覺得,你clear下項目一般都會好,你的Popupwindow又不是一般的寫在xml中需要完整包名,我沒發現你的寫法有問題,倒是Android Studio經常不把你寫的代碼打包到apk中,開發中經常遇到,一半Clear 或 Restart(Pc/Android Studio)可解決.

這個錯誤一般是由于運行環境找不到類或者定義的類創建失敗所造成，一般控件中出現這個錯誤可能是由于該控件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.
