該功能只用在Android 4.4之後的版本使用
5.0以上系統很簡單，直接設定：

try {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        Window window = getWindow();
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.setStatusBarColor(getResources().getColor(R.color
 
.colorPrimary));
        //底部導航欄
        //window.setNavigationBarColor(activity.getResources().getColor(colorResId));
    }
} catch (Exception e) {
            e.printStackTrace();
}

4.4系統兩種方法：

方法一、在xml中設定主題或自定義style，缺點：Android系統碎片化效果不好

1、主題設定：

Theme.Holo.Light.NoActionBar.TranslucentDecor 

2、自定義style：

<style name="AppTheme" parent="AppBaseTheme">  
<!-- Status Bar -->  
<item name="android:windowTranslucentStatus">true</item>  
<!-- Navigation Bar -->  
<item name="android:windowTranslucentNavigation">true</item>  
</style>  

方法二、程式碼修改
可在Activity整合的自定義父類中，如：BaseActivity，在onCreate方法中新增程式碼：

package com.susan.project.myapplication;

import android.annotation.TargetApi; 
import android.app.Activity;    
import android.os.Build; 
import android.os.Bundle; 
import android.view.Window; 
import android.view.WindowManager;

public class MainActivity extends Activity {

       @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.colorPrimary);//狀態列所需顏色

       }
       setContentView(R.layout.activity_main);    }

       @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);    
       }
}
