一项活动(MainActivity)调用一个片段(MainPage)。该片段旨在打开本地资产webview文件Map.html。它按预期工作,但地图不能通过指尖移动。当Map.html打开一个浏览器时,此功能可用。但是,左上方的缩小分接按钮确实有效。无法在webview中移动地图
覆盖webview的东西,它可以被看到但没有被刷过?
初始AppCompatActivity(支持动作条)由MainActivity给出:
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
//list of private declarations
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// a lot of other stuff relating to navigation drawer
// calls MainPage Fragment
android.support.v4.app.Fragment fragment = new MainPage();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.content_frame, fragment)
.addToBackStack("tag")
.commit();
}
}
其中用于此的XML被给定为:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_centerVertical="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/content_frame">
</WebView>
<ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111">
</ListView>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
最终调用的MainPage,给定如:
public class MainPage extends android.support.v4.app.Fragment implements GeolocationPermissions.Callback {
public MainPage() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_main, container, false);
WebView webview = (WebView) rootView.findViewById(R.id.content_frame);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webview.getSettings().setGeolocationEnabled(true);
GeoClient geo = new GeoClient();
webview.setWebChromeClient(geo);
String origin = "";
geo.onGeolocationPermissionsShowPrompt(origin, this);
webview.loadUrl("file:///android_asset/Map.html");
return rootView;
}
