Question

是否可以将缩放添加到移动定位网站？

我使用webview，我需要移动网站的文字更大，我认为如果我能够放大，这可以解决。但是Web.getSettings().setBuiltInZoomControls(true);无效。它不允许我缩放。

编辑： 以下是我现在的情况：

    Web = (WebView) findViewById(R.id.webView1);
    Web.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    Web.getSettings().setJavaScriptEnabled(true);
    Web.getSettings().setBuiltInZoomControls(true);
    Web.getSettings().setPluginsEnabled(true);
    Web.getSettings().setAllowFileAccess(true);
    Web.loadUrl(URL);
    Web.getSettings().setCacheMode( WebSettings.LOAD_NO_CACHE );
    Web.getSettings().setRenderPriority( RenderPriority.HIGH );
    Web.setWebViewClient(new WebViewClient());
    Web.setWebViewClient(new ErrorWebViewClient());

EDIT2：这就是我尝试Mocialov Boris的答案：

View zoom;  
FrameLayout mContentView;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.web);

Web = (WebView) findViewById(R.id.webView1);
Web.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
Web.getSettings().setJavaScriptEnabled(true);
Web.getSettings().setPluginsEnabled(true);
Web.getSettings().setAllowFileAccess(true);
Web.loadUrl(URL);
Web.getSettings().setSupportZoom(true);
Web.getSettings().setCacheMode( WebSettings.LOAD_NO_CACHE );
Web.getSettings().setRenderPriority( RenderPriority.HIGH );
Web.setWebViewClient(new WebViewClient());
Web.setWebViewClient(new ErrorWebViewClient());

mContentView = (FrameLayout) getWindow().getDecorView().findViewById(android.R.id.content);
zoom = Web.getZoomControls();
mContentView.addView(zoom);
zoom.setVisibility(View.GONE);

在此解决方案中，实现处理程序非常重要，因为它将从某个线程对UI进行更改。您说在添加此mContentView.addView(zoom);行后应用程序崩溃了，我认为这就是问题

View zoom;  
FrameLayout mContentView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.web);

    Web = (WebView) findViewById(R.id.webView1);
    Web.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    Web.getSettings().setJavaScriptEnabled(true);
    Web.getSettings().setPluginsEnabled(true);
    Web.getSettings().setAllowFileAccess(true);
    Web.loadUrl(URL);
    Web.getSettings().setSupportZoom(true);
    Web.getSettings().setCacheMode( WebSettings.LOAD_NO_CACHE );
    Web.getSettings().setRenderPriority( RenderPriority.HIGH );
    Web.setWebViewClient(new WebViewClient());
    Web.setWebViewClient(new ErrorWebViewClient());

    mContentView = (FrameLayout) getWindow().getDecorView().findViewById(android.R.id.content);
    zoom = Web.getZoomControls();
    mContentView.addView(zoom);
    zoom.setVisibility(View.GONE);
}

private Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            System.out.println("got msg");
            switch (msg.what) {
            case 0:
                mContentView.addView(zoom);
                break;
            }
        }
}

放大移动网站和webview
