Android使用WebView加載網頁

• AndroidManifest.xml在清單檔案中聲明網絡權限

• activity_webview.xml布局檔案

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

    <WebView
        android:id="@+id/activity_webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</FrameLayout>
           

• MainActivity.java中

public class MainActivity extends Activity {
    private static final String TAG = "WebViewTestActivity";

    private WebView mWebView;

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

        mWebView = (WebView) findViewById(R.id.activity_webview);
        mWebView.getSettings().setJavaScriptEnabled(true);

        mWebView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
                //view.getUrl()
                //TODO
                return false;
            }
        });
        mWebView.loadUrl("http://www.baidu.com");
    }

    @Override
    public void onBackPressed() {
        if (mWebView.canGoBack()) {
            mWebView.goBack();
        } else {
            super.onBackPressed();
        }
    }
}
