Android自定义手机界面状态栏实例代码-编程学习网

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.TranslucentDecor
Theme.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；

2.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。

代码复制进你的项目即可，好了，这些工作完成之后我们来看下效果：

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; 
 }
