Android如何自定义手机界面状态栏，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
前言
我们知道IOS上的应用，状态栏的颜色总能与应用栏颜色保持一致，用户体验很不错，那安卓是否可以呢？若是在安卓4.4之前，答案是否定的，但在4.4之后，谷歌允许开发者自定义状态栏背景颜色啦，这是个不错的体验！若你手机上安装有最新版的qq，并且你的安卓SDK版本是4.4及以上，你可以看下它的效果：
实现这个效果有两个方法： 1.在xml中设置主题或自定义style；
Theme.Holo.Light.NoActionBar.TranslucentDecorTheme.Holo.NoActionBar.TranslucentDecor<style name="AppTheme" parent="AppBaseTheme"> <!-- Status Bar --> <item name="android:windowTranslucentStatus">true</item> <!-- Navigation Bar --> <item name="android:windowTranslucentNavigation">true</item> </style>鉴于市面上各种手机的SDK的各种版本，不建议采用这种方法；
在代码中控制； 这个情况下可创建一个BaseActivity，在onCreate方法中进行处理：
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { setTranslucentStatus(true); SystemBarTintManager tintManager = new SystemBarTintManager(this); tintManager.setStatusBarTintEnabled(true); tintManager.setStatusBarTintResource(R.color.top_bg_color);//通知栏所需颜色 } setContentView(R.layout.main_activity); } @TargetApi(19) private void setTranslucentStatus(boolean on) { Window win = getWindow(); WindowManager.LayoutParams winParams = win.getAttributes(); final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS; if (on) { winParams.flags |= bits; } else { winParams.flags &= ~bits; } win.setAttributes(winParams); }需注意的是， tintManager.setStatusBarTintResource(R.color.top_bg_color);这一步的颜色值（即把你的状态栏颜色与你的栏颜色保持一致）要写在color.xml中去，如果用Color.praseColor则会报错。

貌似已经达到效果了，但仔细观察，好像栏被提上去了，就是说APP界面全屏了，状态了盖在了APP上，恩，这并非我们想要的效果，那如何将界面从状态栏下部开始呢，只需要在Activity的布局文件最外层控件加上一个属性： Android:fitsSystemWindows="true"就可以啦！看下效果： 
这样就达到了咱们最开始的样式。
PS：在使用过程中发现了一些问题，使用以上方法对单个Activity有效，但是对继承了TabActivity的导航页怎么办呢？假如MainActivity继承了TabActivity，Tab1Activity、Tab2Activity、Tab3Activity是三个子项，那么设置状态栏的代码需写在MainActivity中，而 android:fitsSystemWindows="true"需写在三个子Activity的xml布局文件中，这样设置后仍然有问题，就是进入应用后首页也就是Tab1Activity没有问题，而Tab2Activity、Tab3Activity却没达到效果，它们的效果相当于未加android:fitsSystemWindows="true"时的效果，期初我怀疑是Activity不同的原因，因此我把Tab1Activity和Tab3Activity调了下位置，结果Tab3Activity成为首页后正常，而Tab1Activity又不正常了，百思不得姐，最后实在没办法，就在Tab2Activity、Tab3Activity的OnCreate方法中加了几句代码：
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { ((LinearLayout)findViewById(R.id.ll)).setPadding(0, SysUtils.getStatusHeight(this), 0,0); }意思是，先求出状态栏高度，然后设置最外层控件的PaddingTop值为状态栏高度，结果正好达到效果，至于为什么只有首页Activity可以达到效果，而后面的子项无法达到效果，本人也在郁闷中，有知道的朋友可以分享下！ 状态栏高度算法：
public static int getStatusHeight(Activity activity){ int statusHeight = 0; Rect localRect = new Rect(); activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(localRect); statusHeight = localRect.top; if (0 == statusHeight){ Class<?> localClass; try { localClass = Class.forName("com.android.internal.R$dimen"); Object localObject = localClass.newInstance(); int i5 = Integer.parseInt(localClass.getField("status_bar_height").get(localObject).toString()); statusHeight = activity.getResources().getDimensionPixelSize(i5); } catch (ClassNotFoundException e) { e.printStackTrace(); } catch (IllegalAccessException e) { e.printStackTrace(); } catch (InstantiationException e) { e.printStackTrace(); } catch (NumberFormatException e) { e.printStackTrace(); } catch (IllegalArgumentException e) { e.printStackTrace(); } catch (SecurityException e) { e.printStackTrace(); } catch (NoSuchFieldException e) { e.printStackTrace(); } } return statusHeight; }看完上述内容，你们掌握Android如何自定义手机界面状态栏的方法了吗？如果还想学到更多技能或想了解更多相关内容，欢迎关注编程网行业资讯频道，感谢各位的阅读！
