Android 状态栏和应用标题栏颜色保持一致

该功能只用在Android 4.4之后的版本使用
5.0以上系统很简单，直接设置：

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));        //底部导航栏        //window.setNavigationBarColor(activity.getResources().getColor(colorResId));    }} catch (Exception e) {            e.printStackTrace();}

4.4系统两种方法：

方法一、在xml中设置主题或自定义style，缺点：Android系统碎片化效果不好

1、主题设置：

Theme.Holo.Light.NoActionBar.TranslucentDecor

2、自定义style：

方法二、代码修改
可在Activity集成的自定义父类中，如：BaseActivity，在onCreate方法中添加代码：

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);//状态栏所需颜色       }       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);           }}

}如出现标题栏被提上去了，可在Activity根布局及最外层控件加上 Android:fitsSystemWindows="true"属行

PS：在开发过程中继承了TabActivity可能会遇到无效问题，解决办法在上述代码中添加计算高度代码并给视图设置：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {         ((LinearLayout)findViewById(R.id.ll)).setPadding(0, statusBarTop1, 0,0);  }

public static int statusBarTop1(Context mContext) {        Class<?> c = null;        Object obj = null;        Field field = null;        int x = 0, sbar = 0;        try {            c = Class.forName("com.android.internal.R$dimen");            obj = c.newInstance();            field = c.getField("status_bar_height");            x = Integer.parseInt(field.get(obj).toString());            sbar = mContext.getResources().getDimensionPixelSize(x);        } catch (Exception e1) {            LogUtils.e("get status bar height fail");            e1.printStackTrace();        }        return sbar;    }
