android - Webview 仅在新设备​​上全屏显示，在旧设备上不显示

Question

我不明白为什么，如果我在 Nexus5 上试用，一切都很好，但如果我在 4.2.2 LG P880 或 4.1.2 Samsung S2 等旧手机上试用，webview 的内容将不会全屏显示.知道我做错了什么吗？这是我的代码:

@InjectView(R.id.webview) WebView mWebView;
@InjectView(R.id.title_textview)
TextView title;

@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_webview);
    ButterKnife.inject(this);
    Bundle bundle = getIntent().getExtras();

    if(bundle != null){
        String file = "file:///android_asset/webview/";

        if(bundle.getInt("type") == TYPE_TERMS) {
            title.setText(getString(R.string.terns2));
            file += "terms.html";
        }else if(bundle.getInt("type") == TYPE_PRIVACY) {
            title.setText(getString(R.string.privacy_policy2));
            file += "privacy.html";
        }else if(bundle.getInt("type") == TYPE_ATTRIBUTIONS) {
            title.setText(getString(R.string.attributions2));
            file += "attributions.html";
        }else{
            findViewById(R.id.id_bar).setVisibility(View.GONE);
            file = "https://www.facebook.com/PassengerApp";
        }

        mWebView.setInitialScale(1);
        mWebView.getSettings().setLoadWithOverviewMode(true);
        mWebView.getSettings().setUseWideViewPort(true);
        mWebView.setWebChromeClient(new WebChromeClient());
        mWebView.setWebViewClient(new WebViewClient(){
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url){
                return false;
            }
        });

        mWebView.loadUrl(file);
    }
}

@Override
public void onBackPressed() {
    super.onBackPressed();
    overridePendingTransition(R.anim.push_right_in, R.anim.push_right_out);
}

XML:

   <WebView
    android:id="@+id/webview"
    android:layout_marginLeft="12dp"
    android:layout_marginRight="12dp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

PS:如果我加载真实网页，它会正确加载。

这是我使用的 .css:

*{
margin:0;
padding:0;
}

line-height: 1.5em;
}

.bg{

}

.full{

Answer 1

拿出这个:

 mWebView.setInitialScale(1);
 mWebView.getSettings().setLoadWithOverviewMode(true);
 mWebView.getSettings().setUseWideViewPort(true);

并没有使用 css 文件，现在它可以工作了。但是，如果有人知道如何使用 css 文件来完成这项工作，那就太好了。
