        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) {

        } else {
            show();
        }

            actionBar.hide();
        }
        mControlsView.setVisibility(View.GONE);

推荐答案

我发现了问题，只需添加此代码，然后Web视图就适合全屏显示.

I found the problem, just added this code and the webview fitted the fullscreen.

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