（五）在android4.4上设置手机状态栏的背景-创新互联

一、demo效果图

在android 4.4上 有一个新的特性可以设置手机状态栏的背景，让手机整个界面的风格保持一致，在今年的google i/o上的android l默认就是这种风格。来先看一下demo效果图：

      图一：透明状态栏                                                        图2：蓝色背景状态栏

二、整个DEMO的工程结构图如下所示：

三、主要的实现代码如下所示：

首先，要记得导入systembartint-1.0.4.jar包

 3.1 MainActivity.java中的代码如下所示：

package com.example.testdemo;

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

import com.readystatesoftware.systembartint.SystemBarTintManager;

public class MainActivity extends Activity {
private boolean isBarTint = true;
private boolean isTranslucentBarTint = false;

public void setBarTint(boolean isBarTint) {
this.isBarTint = isBarTint;
    }

public void setTranslucentBarTint(boolean isTranslucentBarTint) {
this.isTranslucentBarTint = isTranslucentBarTint;
    }

    @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
if (isBarTint) {
            initSystemBar();
        }else if (isTranslucentBarTint) {
            initTranslucentSystemBar();
        }
    }
    @TargetApi(Build.VERSION_CODES.KITKAT)
private void initSystemBar() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            setTranslucentStatus(true);
            SystemBarTintManager tintManager= new SystemBarTintManager(this);
// 激活状态栏设置            tintManager.setStatusBarTintEnabled(true);
// 激活导航栏设置            tintManager.setNavigationBarTintEnabled(false);

int sbg = getResources().getColor(R.color.titlebar_rl_background);
            tintManager.setTintColor(sbg);
            tintManager.setStatusBarTintColor(sbg);

        }
    }

    @TargetApi(Build.VERSION_CODES.KITKAT)
private void initTranslucentSystemBar() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            setTranslucentStatus(true);
            SystemBarTintManager tintManager= new SystemBarTintManager(this);
// 激活状态栏设置            tintManager.setStatusBarTintEnabled(true);
// 激活导航栏设置            tintManager.setNavigationBarTintEnabled(false);

int sbg = getResources().getColor(R.color.viewfinder_title);
            tintManager.setTintColor(sbg);
            tintManager.setStatusBarTintColor(sbg);
        }
    }

    

    @TargetApi(Build.VERSION_CODES.KITKAT)
private void setTranslucentStatus(boolean isOpen) {
        Window win= getWindow();
        WindowManager.LayoutParams winParams= win.getAttributes();
final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
if (isOpen) {
            winParams.flags|= bits;
        }else {
            winParams.flags&= ~bits;
        }
        win.setAttributes(winParams);
    }

    @TargetApi(Build.VERSION_CODES.KITKAT)
private void setTranslucentNavigation(boolean isOpen) {
        Window win= getWindow();
        WindowManager.LayoutParams winParams= win.getAttributes();
final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION;
if (isOpen) {
            winParams.flags|= bits;
        }else {
            winParams.flags&= ~bits;
        }
        win.setAttributes(winParams);
    }
}

 3.2 colors.xml的颜色值如下所示：

  #33b5e6  #80000000

 3.3 styles.xml中的代码如下所示：

     true   true  

 3.4 AndroidManifest.xml  中application或对应的activity设置主题 android:theme="@style/AppTheme"
