我的应用程序需要实例的WebView 显示一个网站的页面内容。
My app needs to instantiate a WebView that displays the content of a page of a website.
它与手机完美的作品(我试过各种HTC的和最近的三星太),但它不与片(Galaxy Tab的,或者华硕Eee Pad的变压器):不是填充屏幕的的WebView 出现非常小。
It works perfectly with cellphones (I've tried with various HTC's and with a recent Samsung too) but it doesn't with tablets (Galaxy Tab, or Asus Eee Pad Transformer) : instead of filling the screen the WebView appears very small.
根据不同的标签,视区的大约25%至50%的填充,其余为空。它看起来有点好像我是用 WRAP_CONTENT 而不是 FILL_PARENT 。
Depending of the tabs, roughly 25% to 50% of the viewport is filled, the rest is blank. It looks a bit as if I was using WRAP_CONTENT instead of FILL_PARENT.
布局我使用看起来像这样:
The layout I'm using looks like this:
<?xml version="1.0" encoding="utf-8"?> <WebView xmlns:android="schemas.android/apk/res/android" android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent" />的的onCreate()使用此布局的活动是这样的:
The onCreate() of the activity that uses this layout looks like this:
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.showdoc); // showdoc is the layout above // Configuration of the WebView final WebView webview = (WebView) findViewById(R.id.webview); final WebSettings settings = webview.getSettings(); settings.setJavaScriptEnabled(true); // Callbacks setup final Context ctx = this; webview.setWebViewClient(new WebViewClient() { public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { Toast.makeText(ctx, getResources().getString(R.string.error_web) + description, Toast.LENGTH_LONG).show(); } }); // Display of the page webview.loadUrl(getResources().getString(R.string.doc_url) + Locale.getDefault().toString()); }和清单文件看起来是这样的:
And the manifest file looks like this:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="schemas.android/apk/res/android" package="com.example.myapp" android:versionCode="1" android:versionName="1.0"> <uses-permission android:name="android.permission.INTERNET" /> <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> <activity android:name=".MainActivity" android:label="@string/app_name" android:configChanges="keyboardHidden|orientation"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="3" /> </manifest>当我访问相同的URL与普通的浏览器,页面不正确地填满屏幕。
When I access to the same URL with the regular browser, the page does properly fill the screen.
下面的截图中执政。仿真器使用的是三星Galaxy Tab 10条作出,但结果基本上是一个物理的Eee Pad的变压器,在的WebView 为50%,同小。在手机上,没问题,的WebView 采取所有可用的空间。
The screenshot below were made using a Samsung Galaxy Tab 10 in. emulator, but the result is basically the same on a physical Eee Pad Transformer, the WebView being 50% smaller. On a cellphone, no problem, the WebView takes all the available room.
我的应用程序,在横向模式下:
My app, in landscape mode:
我的应用程序,在纵向模式下:
My app, in portrait mode:
同样的网址,相同的硬件,用默认的浏览器,在横向模式下:
Same URL, same hardware, with the default browser, in landscape mode:
同样的网址,相同的硬件,默认浏览器,在人像模式:
Same URL, same hardware, with the default browser, in portrait mode:
因此,它必须是一个设置事
So it must be a matter of settings.
我有什么不成功地设法至今:
- 强制的LayoutParams
我最初以为这是一个的LayoutParams 的问题,所以我尝试添加接下来我的的onCreate(),但没有成功。它只是不会改变任何东西:
I initially thought it was a LayoutParams problem, so I tried adding what follows to my onCreate(), but with no success. It just doesn't change anything:
// Zoom out final Display display = getWindowManager().getDefaultDisplay(); final int width = display.getWidth(); final int height = display.getHeight(); webview.setLayoutParams(new LayoutParams(width, height));- setScrollBarStyle()
- 使用的LinearLayout
我也看了this讨论然后试图 webview.setScrollBarStyle(WebView.SCROLLBARS_INSIDE_OVERLAY); ,但没有成功或者
I also looked at this discussion and then tried webview.setScrollBarStyle(WebView.SCROLLBARS_INSIDE_OVERLAY); , but with no success either.
我试图改变在布局进一步如下您的反馈意见(见下文),但它不会改变任何东西:
I have tried changing the Layout as follows further to your feedback (see below), but it does not change anything:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="schemas.android/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <WebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout>你有什么想法?在此先感谢!
Do you have any idea? Thanks in advance!
推荐答案我的猜测是,它是在平板电脑兼容模式下运行。检查清单文件。你可以发布你所看到的截图?
My guess is that it is running in compatibility mode for tablets. Check your manifest file. Could you post a screenshot of what you are seeing?
我的怀疑是正确的。它在兼容模式下运行。
My suspicion was correct. It is running in compatibility mode.
<supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" android:anyDensity="true" android:xlargeScreens="false" />把这块&LT内部code的;清单&GT; 元素,之前在&lt;应用&GT; 标记。
