android webview ZoomButtonsController 导致android.view.WindowLeaked 问题彻底解决

解决方案

@Override
    public void finish() {
        ViewGroup view = (ViewGroup) getWindow().getDecorView();
        view.removeAllViews();
        super.finish();
    }

附上webview加载html代码

package com.xuecheyi.activity;

import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import com.xuecheyi.BaseActivity;
import com.xuecheyi.mb.R;
import com.xuecheyi.utils.Constant;
import com.xuecheyi.views.TitleManager;

import org.json.JSONObject;
