前言:
Android開發,對于狀態欄的修改,實在是不友好,沒什么api可以用,
不像ios那么方便.但是ui又喜歡只搞ios一套.
沒辦法.各種翻源碼,寫反射.真的蛋疼.
需求場景:
當toolbar及狀態欄需要為白色或淺色時(如簡書),狀態欄由于用的Light風格Theme,字體,圖標也都是白色,會看不清.
如果改變成黑色就很和諧了.
一.修改狀態欄顏色:
改變狀態欄顏色,可以看看這篇文章
傳送門:實現狀態欄(statusbar)漸變效果其實很簡單
傳送門實現的效果:
這種方法實現的狀態欄變色,沒有黑色背景.

使用全屏模式實現的效果如下(QQ的效果):

很明顯的半透明黑色背景.
我用的手機是華為,系統7.0
二.修改狀態欄字體:
通用工具類:
public class StatusBarUtil {
/**
* 設置狀態欄黑色字體圖標，
* 適配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;
}
/**
* 已知系統類型時，設置狀態欄黑色字體圖標。
* 適配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
}
}
/**

*/
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);
}
}
/**

*
* @param window 需要設置的窗口

*/
public static boolean FlymeSetStatusBarLightMode(Window window, boolean dark) {
boolean result = false;
if (window != null) {
try {
WindowManager.LayoutParams lp = window.getAttributes();

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;
}
/**

*
* @param window 需要設置的窗口
* @param dark 是否把狀態欄字體及圖標顏色設置為深色

*/
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);//狀態欄透明且黑色字體
} else {
extraFlagField.invoke(window, 0, darkModeFlag);//清除黑色字體
}
result = true;
} catch (Exception e) {
}
}
return result;
}
}
activity中使用:
StatusBarUtil.setStatusBarLightMode(getWindow());
效果:

出現的問題:
1.statusbar背景色變成了colorPrimaryDark默認顏色,
但是我的配置是白色背景(具體配置代碼見最后).
分析原因:
setSystemUiVisibility()會刷新view的屬性配置.
由于statusbar默認使用colorPrimaryDark屬性.
所以顏色會變回默認顏色

此時步驟一設置背景的方法就會失效.
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:當傳入的resid相同時,就不會再次去設置背景色.

解決辦法:
private void initStatusBar() {
if (statusBarView == null) {
int identifier = getResources().getIdentifier("statusBarBackground", "id", "android");
statusBarView = getWindow().findViewById(identifier);
}
if (statusBarView != null) {
statusBarView.setBackgroundDrawable(null);//在設置前將背景設置為null;
//statusBarView.setBackgroundResource(0); //這樣也可以
statusBarView.setBackgroundResource(MVPConfig.statusDrawable);
}
}
修改后的效果:

三.完整代碼:
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);
//延時加載數據.
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);
}
}
//子類通過復寫該方法,控制是否改變statusbar
protected boolean isStatusBar() {
return MVPConfig.isStatusBar();
}
//子類通過復寫該方法,控制是否需要改變statusbar字體顏色
protected boolean isStatusBarLight() {
return MVPConfig.isStatusBarLight;
}
四.補充:
- 6.0以下,5.0原生系統無法修改字體顏色,用了個比較取巧的辦法,設置成半透明灰色.
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依賴于activity,所以在activity與fragment直接跳轉時,狀態欄不是很適用.
比如:
activity是藍色,fragment需要是白色,fragment需要通過window修改狀態欄顏色.有點麻煩.
