参考了一些文章做了一些修改，变成了自己的工具类。其中有很多地方欠考虑，有待改进，欢迎路过的大佬给点建议。

经过前两篇的介绍我们对如何修改状态栏的效果有了大致的了解，本篇介绍一种使用更加简单的方式，可以先拉到最后查看效果图。

设置主题效果

注意： 要设置fitsSystemWindows为true

true

@color/colorPrimary

@color/colorPrimaryDark

@color/colorAccent

参考SystemBarTint对状态栏的改变方式，添加下面这个类方法，用来设置 API 19 以上的状态栏效果

我们的界面绘制时在DecorView中的，这个类的核心思想就是：

1.获取DecorView

2.绘制状态栏高度的View

3.将view添加到DecorView中

所以我们对状态栏的操作，其实就是对view的操作。在这个类中默认view不显示，改变状态栏的效果时，要调用

setStatusBarTintEnabled(true)

注意：使用这个方法的前提是 状态栏是透明的，因为进行了相关的判断(可以自行修改)

public class SystemBarTintManager {

public static final int DEFAULT_TINT_COLOR = 0x99000000;

private boolean mStatusBarAvailable;

private boolean mStatusBarTintEnabled;

private View mStatusBarTintView;

@TargetApi(19)

public SystemBarTintManager(Activity activity) {

Window win = activity.getWindow();

//获取DecorView

ViewGroup decorViewGroup = (ViewGroup) win.getDecorView();

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

// 检查主题中是否有透明的状态栏

int[] attrs = {android.R.attr.windowTranslucentStatus};

TypedArray a = activity.obtainStyledAttributes(attrs);

try {

mStatusBarAvailable = a.getBoolean(0, false);

} finally {

a.recycle();

}

WindowManager.LayoutParams winParams = win.getAttributes();

int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;//状态栏透明

if ((winParams.flags & bits) != 0) {

mStatusBarAvailable = true;

}

}

if (mStatusBarAvailable) {

setupStatusBarView(activity, decorViewGroup);

}

}

/**

* 初始化状态栏

*

*@param context

*@param decorViewGroup

*/

private void setupStatusBarView(Activity context, ViewGroup decorViewGroup) {

mStatusBarTintView = new View(context);

//设置高度为Statusbar的高度

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, getStatusBarHeight(context));

params.gravity = Gravity.TOP;

mStatusBarTintView.setLayoutParams(params);

mStatusBarTintView.setBackgroundColor(DEFAULT_TINT_COLOR);

//默认不显示

mStatusBarTintView.setVisibility(View.GONE);

//decorView添加状态栏高度的View

decorViewGroup.addView(mStatusBarTintView);

}

/**

* 获取状态栏高度

*

*@param activity

*@return

*/

private int getStatusBarHeight(Activity activity) {

int statusBarHeight = 0;

int resourceId = activity.getResources().getIdentifier("status_bar_height", "dimen", "android");

if (resourceId > 0) {

statusBarHeight = activity.getResources().getDimensionPixelSize(resourceId);

}

return statusBarHeight;

}

/**

* 显示状态栏

*/

public void setStatusBarTintEnabled(boolean enabled) {

mStatusBarTintEnabled = enabled;

if (mStatusBarAvailable) {

mStatusBarTintView.setVisibility(enabled ? View.VISIBLE : View.GONE);

}

}

/**

* 设置状态栏颜色

*

*@param color

*/

public void setStatusBarTintColor(int color) {

if (mStatusBarAvailable) {

mStatusBarTintView.setBackgroundColor(color);

}

}

}

工具类代码

在这段代码中当我们的API 为4.4.+ 但是小于 5.0时使用上述的类

/**

* 修改状态栏颜色，支持4.4以上版本

*@param colorId 颜色

*/

public static void setStatusBarColor(Activity activity, int colorId) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

Window window = activity.getWindow();

window.setStatusBarColor(colorId);

} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

//使用SystemBarTintManager,需要先将状态栏设置为透明

setTranslucentStatus(activity);

SystemBarTintManager systemBarTintManager = new SystemBarTintManager(activity);

systemBarTintManager.setStatusBarTintEnabled(true);//显示状态栏

systemBarTintManager.setStatusBarTintColor(colorId);//设置状态栏颜色

}

}

通用方法为

设置字体颜色为黑色

setImmersiveStatusBar(Activity activity,boolean fontIconDark)

设置状态栏透明

setTranslucentStatus(Activity activity)

设置状态栏的颜色

setStatusBarColor(Activity activity, int colorId)

使用方式

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

StatusBarUtil.setImmersiveStatusBar(this,true);

}

}

第二个参数是设置是否为黑色字体。

我们还可以调用下面代码设置状态栏颜色。

StatusBarUtil.setStatusBarColor(Activity activity, int colorId)

效果

使用时只需要一行代码就可以改变状态栏的字体颜色，是不是很简单呢。
