Android实现修改状态栏背景、字体和图标颜色的方法

前言:

Android开发,对于状态栏的修改,实在是不友好,没什么api可以用,不像ios那么方便.但是ui又喜欢只搞ios一套.没办法.各种翻源码,写反射.真的蛋疼.

需求场景:

当toolbar及状态栏需要为白色或浅色时(如简书),状态栏由于用的Light风格Theme,字体,图标也都是白色,会看不清.如果改变成黑色就很和谐了.

一.修改状态栏颜色:

改变状态栏颜色,可以看看这篇文章.传送门:实现状态栏(statusbar)渐变效果其实很简单

传送门实现的效果:

这种方法实现的状态栏变色,没有黑色背景.

使用全屏模式实现的效果如下(QQ的效果):


很明显的黑色背景.

我用的手机是华为,系统7.0

二.修改状态栏字体:

通用工具类:

public class StatusBarUtil {

/**

* 设置状态栏黑色字体图标,

* 适配4.4以上版本MIUIV、Flyme和6.0以上版本其他Android

*

* @return 1:MIUUI 2:Flyme 3:android6.0

*/

public static int getStatusBarLightMode(Window window) {

int result = 0;

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

if (MIUISetStatusBarLightMode(window, true)) {

result = 1;

} else if (FlymeSetStatusBarLightMode(window, true)) {

result = 2;

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

window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);

result = 3;

} else {//5.0

}

}

return result;

}

/**

* 已知系统类型时,设置状态栏黑色字体图标。

* 适配4.4以上版本MIUIV、Flyme和6.0以上版本其他Android

*/

public static void setStatusBarLightMode(Window window) {

int type = getStatusBarLightMode(window);

if (type == 1) {

MIUISetStatusBarLightMode(window, true);

} else if (type == 2) {

FlymeSetStatusBarLightMode(window, true);

} else if (type == 3) {

window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);

} else {//5.0

}

}

/**

* 清除MIUI或flyme或6.0以上版本状态栏黑色字体

*/

public static void StatusBarDarkMode(Window window) {

int type = getStatusBarLightMode(window);

if (type == 1) {

MIUISetStatusBarLightMode(window, false);

} else if (type == 2) {

FlymeSetStatusBarLightMode(window, false);

} else if (type == 3) {

window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);

}

}

/**

* 设置状态栏图标为深色和魅族特定的文字风格

* 可以用来判断是否为Flyme用户

*

* @param window 需要设置的窗口

* @param dark 是否把状态栏字体及图标颜色设置为深色

* @return boolean 成功执行返回true

*/

public static boolean FlymeSetStatusBarLightMode(Window window, boolean dark) {

boolean result = false;

if (window != null) {

try {

WindowManager.LayoutParams lp = window.getAttributes();

Field darkFlag = WindowManager.LayoutParams.class

.getDeclaredField("MEIZU_FLAG_DARK_STATUS_BAR_ICON");

Field meizuFlags = WindowManager.LayoutParams.class

.getDeclaredField("meizuFlags");

darkFlag.setAccessible(true);

meizuFlags.setAccessible(true);

int bit = darkFlag.getInt(null);

int value = meizuFlags.getInt(lp);

if (dark) {

value |= bit;

} else {

value &= ~bit;

}

meizuFlags.setInt(lp, value);

window.setAttributes(lp);

result = true;

} catch (Exception e) {

}

}

return result;

}

/**

* 设置状态栏字体图标为深色,需要MIUIV6以上

*

* @param window 需要设置的窗口

* @param dark 是否把状态栏字体及图标颜色设置为深色

* @return boolean 成功执行返回true

*/

public static boolean MIUISetStatusBarLightMode(Window window, boolean dark) {

boolean result = false;

if (window != null) {

Class clazz = window.getClass();

try {

int darkModeFlag = 0;

Class layoutParams = Class.forName("android.view.MiuiWindowManager$LayoutParams");

Field field = layoutParams.getField("EXTRA_FLAG_STATUS_BAR_DARK_MODE");

darkModeFlag = field.getInt(layoutParams);

Method extraFlagField = clazz.getMethod("setExtraFlags", int.class, int.class);

if (dark) {

extraFlagField.invoke(window, darkModeFlag, darkModeFlag);//状态栏透明且黑色字体

} else {

extraFlagField.invoke(window, 0, darkModeFlag);//清除黑色字体

}

result = true;

} catch (Exception e) {

}

}

return result;

}

}

activity中使用:

StatusBarUtil.setStatusBarLightMode(getWindow());

效果:


出现的问题:

1.statusbar背景色变成了colorPrimaryDark默认颜色,但是我的配置是白色背景(具体配置代码见最后).

分析原因:

setSystemUiVisibility()会刷新view的属性配置.由于statusbar默认使用colorPrimaryDark属性.所以颜色会变回默认颜色


此时步骤一设置背景的方法就会失效.

private void initStatusBar() {

if (statusBarView == null) {

int identifier = getResources().getIdentifier("statusBarBackground", "id", "android");

statusBarView = getWindow().findViewById(identifier);

}

if (statusBarView != null) {

statusBarView.setBackgroundResource(MVPConfig.statusDrawable);

}

}

原因:当传入的resid相同时,就不会再次去设置背景色.


解决办法:

private void initStatusBar() {

if (statusBarView == null) {

int identifier = getResources().getIdentifier("statusBarBackground", "id", "android");

statusBarView = getWindow().findViewById(identifier);

}

if (statusBarView != null) {

statusBarView.setBackgroundDrawable(null);//在设置前将背景设置为null;

statusBarView.setBackgroundResource(MVPConfig.statusDrawable);

}

}

修改后的效果:


三.完整代码:

1.MvpConfig

public class MVPConfig {

public static int statusDrawable;

public static int toolbarBackgroundColor;

public static int toolbarBackgroundDrawable;

public static int backDrawable;

public static boolean isStatusBarLight;

public static void setStatusbarDrawable(@DrawableRes int statusDraw) {

statusDrawable = statusDraw;

}

public static boolean isStatusBar() {

return statusDrawable > 0;

}

public static void setToolbarDrawable(int toolbarBackgroundDrawable) {

MVPConfig.toolbarBackgroundDrawable = toolbarBackgroundDrawable;

}

public static void setBackDrawable(int backDrawable) {

MVPConfig.backDrawable = backDrawable;

}

public static void setIsStatusBarLight(boolean isStatusBarLight) {

if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP_MR1) {

MVPConfig.statusDrawable = Color.parseColor("#33ffffff");

}

MVPConfig.isStatusBarLight = isStatusBarLight;

}

2.Application中

 

@Override

public void onCreate() {

super.onCreate();

MVPConfig.setToolbarDrawable(R.color.white);

MVPConfig.setStatusbarDrawable(R.color.white);

MVPConfig.setBackDrawable(R.drawable.back);

MVPConfig.setIsStatusBarLight(true);

}

3.BaseActivity

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

//延时加载数据.

Looper.myQueue().addIdleHandler(new MessageQueue.IdleHandler() {

@Override

public boolean queueIdle() {

if (isStatusBarLight()) {

StatusBarUtil.setStatusBarLightMode(getWindow());

}

if (isStatusBar()) {

initStatusBar();

getWindow().getDecorView().addOnLayoutChangeListener(new View.OnLayoutChangeListener() {

@Override

public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {

initStatusBar();

}

});

}

mPresenter.initData();

return false;

}

});

}

private void initStatusBar() {

if (statusBarView == null) {

int identifier = getResources().getIdentifier("statusBarBackground", "id", "android");

statusBarView = getWindow().findViewById(identifier);

}

if (statusBarView != null) {

if (isStatusBarLight()) {

statusBarView.setBackgroundDrawable(null);

}

statusBarView.setBackgroundResource(MVPConfig.statusDrawable);

}

}

//子类通过复写该方法,控制是否改变statusbar

protected boolean isStatusBar() {

return MVPConfig.isStatusBar();

}

//子类通过复写该方法,控制是否需要改变statusbar字体颜色

protected boolean isStatusBarLight() {

return MVPConfig.isStatusBarLight;

}

四.补充:

6.0以下,5.0原生系统无法修改字体颜色,用了个比较取巧的办法,设置成半透明灰色.

public static void setStatusBarLightMode(Window window) {

int type = getStatusBarLightMode(window);

if (type == 1) {

MIUISetStatusBarLightMode(window, true);

} else if (type == 2) {

FlymeSetStatusBarLightMode(window, true);

} else if (type == 3) {

window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);

} else {

//5.0

if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP_MR1) {

MVPConfig.statusDrawable = Color.parseColor("#33ffffff");

}

}

}

由于是直接修改window中的statusbarview的背景,而frgament依赖于activity,所以在activity与fragment直接跳转时,状态栏不是很适用.比如:activity是蓝色,fragment需要是白色,fragment需要通过window修改状态栏颜色.有点麻烦.
