让 Webview 在 Android 中占据整个对话框 window

Question

我的应用程序中有一个对话框片段，我想占据整个屏幕。因为我需要我的片段来扩展我的自定义布局，并想动态地向这个对话框添加视图，所以我编写了如下代码：-

my_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<com.example.MyDialogRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/dialogRootLayout"
    android:orientation="vertical"
    android:background="#FFFFFF"
     >

</com.example.MyDialogRelativeLayout>

现在在我的对话框中 java class 我写道：-

MyDialogFragment.java

public class MyDialogFragment extends DialogFragment {

    WebView webView;
    MyDialogRelativeLayout dialogLayout;
    String url;



    public MyDialogFragment(String url)
    {
        this.url = url;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub

        View rootView = inflater.inflate(R.layout.my_custom_dialog,container, false);


        dialogLayout = (MyDialogRelativeLayout) rootView.findViewById(R.id.dialogRootLayout);

        return rootView;
    }


    @Override
    public void onStart() {
        // TODO Auto-generated method stub
        super.onStart();
        DisplayMetrics dm = new DisplayMetrics();
        getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);
        int height = dm.heightPixels;
        int width = dm.widthPixels;
        Log.d("Dialog","Height = "+height+" Widht = "+width);
        getDialog().getWindow().setLayout(width-50,height);


        RelativeLayout.LayoutParams paramsWeb = new RelativeLayout.LayoutParams(width,height);
        final WebView wv = new WebView(getActivity());
        wv.getSettings().setJavaScriptEnabled(true);
        wv.loadUrl(url);

        wv.setWebViewClient(new WebViewClient(){

            @Override
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
                {
                    wv.loadUrl("file:///android_res/raw/nointernet.html");
                }
            });
        dialogLayout.addView(wv,paramsWeb);


        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
        params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
        params.addRule(RelativeLayout.ALIGN_PARENT_TOP);

        Button closeButton = new Button(getActivity());
        closeButton.setText("Close");
        closeButton.setBackground(null);
        dialogLayout.addView(closeButton,params);


        closeButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                getDialog().dismiss();

            }
        });


    }



    public class myWebViewClient extends WebViewClient{



        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            // TODO Auto-generated method stub
            view.loadUrl(url);
            return true;
        }


    }

我的问题是，webview 没有占据绘制到屏幕上的整个对话框 window。 dialog上面有一个黑色的layer/area，下面是webview.

如何去除顶部的黑色部分，让 webview 填满整个对话框？

Answer 1

使用以下设置片段内的高度和宽度 class：getDialog().getWindow().setLayout(width, height);

要删除黑色部分（标题），请在您的片段中使用以下内容 class：getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
