安卓開發之嵌入H5

1、開啓網絡權限

AndroidManifest.xml

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

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

    <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:theme="@style/AppTheme">
        <activity
                android:name=".MainActivity"
                android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

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


</manifest>

2、隱藏頂部導航欄

styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

3、MainActivity

啓動初始化頁面

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

        //實例化WebView對象
        webview = new WebView(this);
        //設置WebView屬性，能夠執行Javascript腳本
        webview.getSettings().setJavaScriptEnabled(true);
        //支持alert的方法
        webview.setWebChromeClient(new WebChromeClient());
        //覆蓋WebView默認使用第三方或系統默認瀏覽器打開網頁的行爲，使網頁用WebView打開
        webview.setWebViewClient(new WebViewClient(){
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }
        });
        try {
            //設置打開的頁面地址
            webview.loadUrl("https://www.atage.cn/op/open/login");
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
        }
        setContentView(webview);
    }
