Android(安卓)4.4以后设置状态栏颜色

前置条件：Android开发包4.4或以上
创建布局：布局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.cn.statusbar.MainActivity" >    <View  android:id="@+id/statusBarBackground1" android:layout_width="match_parent" android:layout_height="wrap_content" android:visibility="gone" /></RelativeLayout>

第二步：创建Activity

package com.cn.statusbar;import android.annotation.SuppressLint;import android.app.Activity;import android.os.Build;import android.os.Bundle;import android.util.TypedValue;import android.view.View;import android.view.Window;import android.view.WindowManager;@SuppressLint("InlinedApi")public class MActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState)    {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));    }    public void setStatusBarColor(View statusBar,int color){        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {               Window w = getWindow();               w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);               //status bar height               int actionBarHeight = getActionBarHeight();               int statusBarHeight = getStatusBarHeight();               //action bar height               statusBar.getLayoutParams().height = actionBarHeight + statusBarHeight;               statusBar.setBackgroundColor(color);         }    }    public int getActionBarHeight() {        int actionBarHeight = 0;        TypedValue tv = new TypedValue();        if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))        {           actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());        }        return actionBarHeight;    }    public int getStatusBarHeight() {        int result = 0;        int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");        if (resourceId > 0) {            result = getResources().getDimensionPixelSize(resourceId);        }        return result;    }}

OK了，看看代码就知道什么意思了
