关于WebVIew的使用详解

首先是Ui布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/white" />

    <ProgressBar
        android:id="@+id/pb_web_progress"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="match_parent"
        android:layout_height="5dp"
        android:max="100" />

    <WebView
        android:id="@+id/wv_myweb"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

接下来带业务逻辑代码块

package cn.yuan.qi.common.activity;

import android.os.Bundle;
import android.view.View;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;

import butterknife.Bind;
import cn.yuan.qi.R;
import cn.yuan.qi.common.util.L;

/**  * Created by yukuo on 2016/3/16.  * 这是一个显示网页的界面  */ public class WebActivity extends BaseActivity {

    @Bind(R.id.wv_myweb)
    WebView wvMyweb;
    @Bind(R.id.pb_web_progress)
    ProgressBar pbWebProgress;

    @Override
    public void initdata(Bundle extras) {
        wvMyweb.setVerticalScrollbarOverlay(true); //指定的垂直滚动条有叠加样式
        WebSettings settings = wvMyweb.getSettings();
        settings.setUseWideViewPort(true);//设定支持viewport
        settings.setBuiltInZoomControls(true);
        settings.setSupportZoom(true);//设定支持缩放
        /**  * 防止使用默认的浏览器  */  wvMyweb.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return super.shouldOverrideUrlLoading(view, url);
            }
        });
        wvMyweb.setWebChromeClient(new WebChromeClient() {
            @Override
            public void onProgressChanged(WebView view, int newProgress) {
                pbWebProgress.setProgress(newProgress);
                L.i("webview进度", newProgress + "");
                if (newProgress == 100) {
                    pbWebProgress.setVisibility(View.INVISIBLE);
                } else {
                    pbWebProgress.setVisibility(View.VISIBLE);
                }
                super.onProgressChanged(view, newProgress);
            }

        });
          String url = "http://blog.csdn.net/easkshark?viewmode=contents";
        wvMyweb.loadUrl(url);
    }

    @Override
    public int getContentLayout() {
        return R.layout.activity_web;
    }
}
