WebView 显示网页

1.布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:andro></WebView>
</RelativeLayout>

 

2.权限设置

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:andro />
            </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);
