Question

我正在开发一个webview应用程序，我的问题是右边和左边有一个边距我是初学者我不知道如何删除它们请帮助。注意：请在您的答案中具体说明：例如：在名为layout的java框中的全屏内容中添加此代码。

提前多多感谢，以下是代码： 1- layout-全屏活动文件夹

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_fullscreen);
        WebView view = (WebView) this.findViewById(R.id.webView);
        view.setWebViewClient(new WebViewClient());
        view.loadUrl("http://google.com");

        view.getSettings().setJavaScriptEnabled(true);

        mVisible = true;
        mControlsView = findViewById(R.id.webView);
        mContentView = findViewById(R.id.webView);


        // Set up the user interaction to manually show or hide the system UI.
        mContentView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                toggle();
            }
        });

        // Upon interacting with UI controls, delay any scheduled hide()
        // operations to prevent the jarring behavior of controls going away
        // while interacting with the UI.

    }



    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);

// Trigger the initial hide() shortly after the activity has been
        // created, to briefly hint to the user that UI controls
        // are available.
        delayedHide(100);


    }

    private void toggle() {
        if (mVisible) {
            hide();
        } else {
            show();
        }
    }

    private void hide() {
        // Hide UI first
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.hide();
        }
        mControlsView.setVisibility(View.GONE);
        mVisible = false;

Answer 1

我发现了问题，只是添加了此代码，并且webview适合全屏。

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

Answer 2

除了您提到的文件之外，还有其他任何xml文件吗？您可能有另一个父级布局。具有保证金的父布局可以解释最新情况。
