Question

片段中的webview在android 4.4.x之前没有调用select javascipt fucntion change（）。系统浏览器可以这样做。但是Activity中的webview可以调用。请帮助我。

mi_fragment_tab_test.xml

<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="com.tanliani.fragment.TabHomeFragment" >

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

</RelativeLayout>

TabTestFragment.java

public class TabTestFragment extends Fragment {

    private static final String TAG = TabTestFragment.class.getSimpleName();

    private View view;
    private WebView mCurrentWebView;
    private HashMap<String, String> additionalHttpHeaders = new HashMap<String, String>();
    private Context context;

    public static TabTestFragment newInstance() {
        TabTestFragment fragment = new TabTestFragment();
        return fragment;
    }

    public TabTestFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        Logger.i(TAG, "onCreate :: savedInstanceState = " + savedInstanceState);
        super.onCreate(savedInstanceState);
        context = getActivity();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        view = inflater
                .inflate(R.layout.mi_fragment_tab_test, container, false);
        mCurrentWebView = (WebView) view.findViewById(R.id.mi_tab_test_webview);
        WebSettings setting = mCurrentWebView.getSettings();
        setting.setJavaScriptEnabled(true);
        setting.setUserAgentString("Mi-Android");
        mCurrentWebView.setWebChromeClient(new WebChromeClient());
        mCurrentWebView.setWebViewClient(new WebViewClient());

        additionalHttpHeaders.put("unique_id", DeviceUtils.getIMEI(context));
        additionalHttpHeaders.put("ApiKey", "76b86bbd");

        // mCurrentWebView.loadUrl(CommonDefine.MI_H5_MEMBERS_SEARCH);
        mCurrentWebView.loadUrl("file:///android_asset/select.html");

        return view;
    }

    @Override

        super.onAttach(activity);

    @Override

        Logger.i(TAG, "onResume :: ");
        super.onResume();
    }

    @Override

        Logger.i(TAG, "onStop :: ");
        super.onStop();

FragmentTabHost中的片段

@Override
protected void onCreate(Bundle savedInstanceState) {

    Logger.i(TAG, "onCreate :: savedInstanceState = " + savedInstanceState);
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.mi_activity_main);
    context = this;

    // View
    mFragmentManager = getSupportFragmentManager();
    mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup(this, mFragmentManager, android.R.id.tabcontent);
    TabWidget mTabWidget = (TabWidget) findViewById(android.R.id.tabs);
    if (Build.VERSION.SDK_INT >= 11) {
        mTabWidget.setShowDividers(LinearLayout.SHOW_DIVIDER_NONE);
    }

    ...

    // Test
    mTabHost.addTab(
            mTabHost.newTabSpec(TAB_TAG_Test).setIndicator(
                    newTabItem(R.drawable.mi_selector_tab_search,
                            R.string.mi_navi_title_search)),
            TabTestFragment.class, null);

    ...
    }
