如何以固定的宽度和高度显示Webview

如何以固定的宽度和高度显示Webview

您可以使用

LinearLayout

而不是

RelativeLayout

拆分屏幕。只需将高度设置为0并将重量设置为1

GLSurfaceView

并将

WebView

两者都设置。在您的情况下，代码将为：

LinearLayout layout = new LinearLayout(this); // Use LinearLayout instead of RelativeglView = new GLSurfaceView(this);glView.setRenderer(this);glView.setZOrderMediaOverlay(false);// height is 0, weight is 1LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 0, 1);layout.addView(glView, params);webView = new WebView(this);this.showWV(false); //handler message , i hide it in certain screen.webView.getSettings().setJavascriptEnabled(true);webView.getSettings().setLoadWithOverviewMode(true);webView.getSettings().setUseWideViewPort(true);// height is 0, weight is 1params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 0, 1);layout.addView(webView, params);webView.loadUrl("http://stackoverflow.com");setContentView(layout);

或者，您可以使用

RelativeLayout

硬编码的高度和宽度值：

RelativeLayout layout = new RelativeLayout(this); // Use LinearLayout instead of RelativeglView = new GLSurfaceView(this);glView.setRenderer(this);glView.setZOrderMediaOverlay(false);glView.setId(123); // set idRelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(640, 480);layout.addView(glView, params);webView = new WebView(this);this.showWV(false); //handler message , i hide it in certain screen.webView.getSettings().setJavascriptEnabled(true);webView.getSettings().setLoadWithOverviewMode(true);webView.getSettings().setUseWideViewPort(true);params = new RelativeLayout.LayoutParams(640, 480);params.addRule(RelativeLayout.BELOW, glView.getId()); // set WebView position is below GLSurfaceViewlayout.addView(webView, params);webView.loadUrl("http://stackoverflow.com");setContentView(layout);

UPD： 不带硬编码值，使用不可见视图：

RelativeLayout layout = new RelativeLayout(this); // Use LinearLayout instead of Relative// create a fake view with zero size and place it to center of RelativeLayoutView fakeView = new View(this); fakeView.setId(24736); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(0, 0);params.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);layout.addView(fakeView, params);glView = new GLSurfaceView(this);glView.setRenderer(this);glView.setZOrderMediaOverlay(false);glView.setId(123); // set idparams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);params.addRule(RelativeLayout.ABOVE, fakeView.getId()); // set position is above fakeViewlayout.addView(glView, params);webView = new WebView(this);this.showWV(false); //handler message , i hide it in certain screen.webView.getSettings().setJavascriptEnabled(true);webView.getSettings().setLoadWithOverviewMode(true);webView.getSettings().setUseWideViewPort(true);params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);params.addRule(RelativeLayout.BELOW, fakeView.getId()); // set WebView position is below fakeViewlayout.addView(webView, params);webView.loadUrl("http://stackoverflow.com");setContentView(layout);
