本文介绍了我的WebView没有填满标签“屏幕(但充满了手机的屏幕没有PB)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

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="http://schemas.android.com/apk/res/android"
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
/> 

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="http://schemas.android.com/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()

  • 我也看了<一个href=\"http://stackoverflow.com/questions/3859502/why-isnt-my-webview-filling-up-the-entire-width-of-my-screen\">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.


    • 使用的LinearLayout

    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="http://schemas.android.com/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。
