Android 沉浸式状态栏设计以及ContentView获取
来源：互联网 发布：windows帮助与支持 编辑：程序博客网 时间：2024/06/05 16:27
使用了popWindow，并且需求指明了popWindow必须是和Activity类似的全屏模式，并且从页面底部弹出！
titleView，ActionBar的获取相对复杂，具体来说titleView显得更另类，具体参考Android 自定义TitleBar替换ActionBar的另类方式
还可以使用Resource对象获取（推荐这种方式）
注意：状态栏透明可能导致布局向上便宜，所以需要设置根布局的android:fitsSystemWindows="true"
当popWindow所有设计完毕后，从底部弹出popWindow,发现设置在popWindow的上的titlebar一部分被压入状态栏的底部了，也就是说全屏是全屏了，但是超过了应有的部分！
解决方案：
ContentView的获取
view contentView = ((ViewGroup)getWindow().getDecorView().findViewById(android.R.id.content)).getChildAt(0);
titleView，ActionBar的获取相对复杂，具体来说titleView显得更另类，具体参考Android 自定义TitleBar替换ActionBar的另类方式
为了达到良好的兼容性，我们可以如下变现代码
/** * 用于获取状态栏的高度。 * * @return 返回状态栏高度的像素值。 */private int getStatusBarHeight() { int statusBarHeight = 0; try { Class<?> c = Class.forName("com.android.internal.R$dimen"); Object o = c.newInstance(); Field field = c.getField("status_bar_height"); int x = (Integer) field.get(o); statusBarHeight = getResources().getDimensionPixelSize(x); } catch (Exception e) { e.printStackTrace(); Rect frame = new Rect(); getWindow().getDecorView().getWindowVisibleDisplayFrame(frame); statusBarHeight = frame.top; } return statusBarHeight;还可以使用Resource对象获取（推荐这种方式）
private int getStatusBarHeight() { int result = 0; int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android"); if (resourceId > 0) { result = res.getDimensionPixelSize(resourceId); } return result; }公司有测试人员发现，FlymeOS4.x/Android4.4.4出现 了问题，让人一头雾水，因此，这里把问题再次改正一下，目前Android4.4.4的系统不多，只检测到魅族的FlymeOS4.x有问题，所以对FlymeOS着重处理一下。
手写判断是否是Flyme OsS 4.x.x
private boolean isFlymeOs4x(){ String sysVersion = android.os.Build.VERSION.RELEASE; if("4.4.4".equals(sysVersion)) { String sysIncrement = android.os.Build.VERSION.INCREMENTAL; String displayId = android.os.Build.DISPLAY; if(!TextUtils.isEmpty(sysIncrement)) { return sysIncrement.contains("Flyme_OS_4"); } else { return displayId.contains("Flyme OS 4"); } } return false;}然后PopWindow改为int statusBarHeight = getStatusBarHeight();if(isFlymeOs4x()){ searchFlightListWindow.setHeight(screenMetrics.heightPixels-statusBarHeight*2); //至于这里为什么乘以2，我只能说，除了鬼鬼们，只有魅族自己知道，我是发现获得的StatusBarHeight偏小，所以乘以2，实践检验是正确的，但也很无语 searchFlightListWindow.showAtLocation(findViewById(R.id.main), Gravity.BOTTOM, 0, 0);}else{ searchFlightListWindow.setHeight(screenMetrics.heightPixels-statusBarHeight); searchFlightListWindow.showAtLocation(findViewById(R.id.main), Gravity.BOTTOM, 0, 0);} View contentView = getWindow().getDecorView().findViewById(android.R.id.content);
View contentView = getWindow().getDecorView().getChildAt(0);
View titleView = findViewById(Window.ID_ANDROID_CONTENT);
