WebView 显示网页

1.布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="net.pericles.andoidab.muiaps.MainActivity">

   <WebView
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       android:id="@+id/wevsss"></WebView>
</RelativeLayout>

 

2.权限设置

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="net.pericles.andoidab.muiaps">

    <!--添加权限-->
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

3.java代码实现

private WebView webViews;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    webViews = (WebView)findViewById(R.id.wevsss);
    webViews.loadUrl("http://www.baidu.com");
    webViews.getSettings().setLoadWithOverviewMode(true);
    webViews.getSettings().setUseWideViewPort(true);
    webViews.getSettings().setJavaScriptEnabled(true);

    webViews.setWebViewClient(new WebViewClient()
    {
        public  boolean shouldOvertideUrlLoading(WebView view ,String url)
        {
            view.loadUrl(url);
            return super.shouldOverrideUrlLoading(view,url);
        }
    });
}

4.注意

    <!--添加权限-->
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>

5.细节

、

 今天在做项目时,发现webview加载的url太大,导致显示上有点畸形,所以想webview最好能自适应屏幕,于是乎baidu，google,webview还真给我们提供了这种方法,如下代码： 

    webViews.getSettings().setLoadWithOverviewMode(true);
    webViews.getSettings().setUseWideViewPort(true);
