抱歉,我一直在搜索此论坛,但没有确切答案。所以我问自己的。
我有一堂课,用目标纵向屏幕640x960显示glView和webview两种布局。我计划拆分布局。因此我的背景看起来是在(0,0,640,480)或纵向屏幕的一半处绘制的。,我想在(0,481,640,479)处绘制我的Web视图,该视图占据了从中间到底部的另一半。但是,我失败了,无法弄清楚如何实现我想要的布局。如何设置webView的大小和位置?
PS:如果我将布局设置为与底部对齐,则Web视图的确处于中间到底部的位置,但是我需要指定确切的位置..最坏的..当它加载url时,它将使用整个屏幕,覆盖我所有的第一个布局,我迷路了。因此如何使WebView将加载的URL显示到WebView中指定的宽度和高度。
谢谢..对不起,我的英语不好。
无论如何,这是我的代码(我以编程方式创建了所有代码,没有使用任何xml布局)
glView = new GLSurfaceView(this); glView.setRenderer(this); glView.setZOrderMediaOverlay(false); layout = new RelativeLayout(this); layout.addView(glView); 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); webView.loadUrl("http://stackoverflow.com"); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); layout.addView(webView, params); setContentView(layout);
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
RelativeLayout
GLSurfaceView
WebView
LinearLayout layout = new LinearLayout(this); // Use LinearLayout instead of Relative glView = new GLSurfaceView(this); glView.setRenderer(this); glView.setZOrderMediaOverlay(false); // height is 0, weight is 1 LinearLayout.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 1 params = 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 Relative glView = new GLSurfaceView(this); glView.setRenderer(this); glView.setZOrderMediaOverlay(false); glView.setId(123); // set id RelativeLayout.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 GLSurfaceView layout.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 RelativeLayout View 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 id params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); params.addRule(RelativeLayout.ABOVE, fakeView.getId()); // set position is above fakeView 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(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); params.addRule(RelativeLayout.BELOW, fakeView.getId()); // set WebView position is below fakeView layout.addView(webView, params); webView.loadUrl("http://stackoverflow.com"); setContentView(layout);
