我在我的应用程序中使用滑块面板。
现在,我的问题是当我将设备屏幕旋转为肖像时,它的宽度不会改变。我尝试更改一些代码,它的宽度是完美的,但也有错误。所以请检查一下。
我的代码如下。 slidingPanel是LinearLayout,因此需要设置宽度。
代码:
metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
panelWidth = (int) ((metrics.widthPixels) * 0.70);
headerPanel = (RelativeLayout) findViewById(R.id.header);
headerPanelParameters = (LinearLayout.LayoutParams) headerPanel
.getLayoutParams();
headerPanelParameters.width = metrics.widthPixels;
headerPanel.setLayoutParams(headerPanelParameters);
menuPanel = (RelativeLayout) findViewById(R.id.menuPanel);
menuPanelParameters = (FrameLayout.LayoutParams) menuPanel
.getLayoutParams();
menuPanelParameters.width = panelWidth;
menuPanel.setLayoutParams(menuPanelParameters);
slidingPanel = (LinearLayout) findViewById(R.id.slidingPanel);
slidingPanelParameters = (FrameLayout.LayoutParams) slidingPanel
.getLayoutParams();
slidingPanelParameters.width = metrics.widthPixels;
slidingPanel.setLayoutParams(slidingPanelParameters);
答案 0 :(得分:0)
FILL_PARENT由静态final int ViewGroup.FILL_PARENT表示。但请注意,自API版本8起,FILL_PARENT已被MATCH_PARENT取代。因此,在LinearLayout.LayoutParams对象中使用它以编程方式设置FILL_PARENT。
