让状态栏颜色跟应用主色调一致布局内容不占有状态栏的位置
设置非全屏的状态栏颜色
/*** 设置不全屏内容的状态栏颜色。** param activity 需要设置的activity* param statusBarColor 状态栏颜色值* param statusBarAlpha 状态栏透明度*/
public static void setStatusBar(Activity activity, ColorInt int statusBarColor, IntRange(from 0, to 255) int statusBarAlpha) {if (Build.VERSION.SDK_INT Build.VERSION_CODES.M) {// 6.0 支持根据状态栏颜色定制浅色和深色的文字和图标activity.getWindow().setStatusBarColor(statusBarColor);int option;if (isDarkColor(statusBarColor)) {// 深色状态栏则让状态栏文字和图标变白option View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR;} else {// 浅色状态栏则让状态栏文字和图标变黑option View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_VISIBLE;}activity.getWindow().getDecorView().setSystemUiVisibility(option);} else if (Build.VERSION.SDK_INT Build.VERSION_CODES.LOLLIPOP) {// 5.xactivity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);activity.getWindow().setStatusBarColor(calculateColor(statusBarColor, statusBarAlpha));} else if (Build.VERSION.SDK_INT Build.VERSION_CODES.KITKAT) {// 4.4 自己创建一个色块加到DecorViewactivity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);ViewGroup decorView (ViewGroup) activity.getWindow().getDecorView();View doraStatusBarView decorView.findViewById(DORA_STATUS_BAR_VIEW_ID);if (doraStatusBarView ! null) {if (doraStatusBarView.getVisibility() View.GONE) {doraStatusBarView.setVisibility(View.VISIBLE);}doraStatusBarView.setBackgroundColor(calculateColor(statusBarColor, statusBarAlpha));} else {decorView.addView(createStatusBarView(activity, statusBarColor, statusBarAlpha));}setFitsSystemWindow(activity);} else {// 4.4 不可定制黑色状态栏无解}
}检测状态栏的颜色以确定用深色还是浅色的文字和图标
/*** 状态栏是否是深色。** param color 状态栏颜色值*/
public static boolean isDarkColor(ColorInt int color) {int gray (int) (Color.red(color) * 0.299 Color.green(color) * 0.587 Color.blue(color) * 0.114);return gray 192;
}自己创建一个和状态栏一样高度的色块。
/*** 生成一个和状态栏大小相同的矩形条。** param activity 需要设置的activity* param color 状态栏颜色值* param alpha 状态栏透明度* return 状态栏矩形条*/
private static View createStatusBarView(Activity activity, ColorInt int color, int alpha) {// 绘制一个和状态栏一样高的矩形View statusBarView new View(activity);LinearLayout.LayoutParams params new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(activity));statusBarView.setLayoutParams(params);statusBarView.setBackgroundColor(calculateColor(color, alpha));statusBarView.setId(DORA_STATUS_BAR_VIEW_ID);return statusBarView;
}根布局设置fitsSystemWindow
private static void setFitsSystemWindow(Activity activity) {ViewGroup parent (ViewGroup) activity.findViewById(android.R.id.content);for (int i 0, count parent.getChildCount(); i count; i) {View childView parent.getChildAt(i);if (childView instanceof ViewGroup) {childView.setFitsSystemWindows(true);((ViewGroup) childView).setClipToPadding(true);}}
}获取状态栏的高度
private static int getStatusBarHeight(Context context) {int resourceId context.getResources().getIdentifier(status_bar_height, dimen, android);return context.getResources().getDimensionPixelSize(resourceId);
}计算带透明度后的颜色
private static int calculateColor(ColorInt int color, int alpha) {if (alpha 0) {return color;}float a 1 - alpha / 255f;int red color 16 0xff;int green color 8 0xff;int blue color 0xff;red (int) (red * a 0.5);green (int) (green * a 0.5);blue (int) (blue * a 0.5);return 0xff 24 | red 16 | green 8 | blue;
}让布局内容的顶部成为状态栏的一部分状态栏透明
public static void setFullScreenStatusBar(Activity activity) {if (Build.VERSION.SDK_INT Build.VERSION_CODES.LOLLIPOP) {activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);activity.getWindow().setStatusBarColor(Color.TRANSPARENT);} else {activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);}activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}DrawerLayout设置状态栏颜色
设置DrawerLayout的状态栏一半的颜色
public static void setStatusBar(Activity activity, DrawerLayout drawerLayout, ColorInt int statusBarColor,IntRange(from 0, to 255) int statusBarAlpha) {if (Build.VERSION.SDK_INT Build.VERSION_CODES.KITKAT) {return;}if (Build.VERSION.SDK_INT Build.VERSION_CODES.LOLLIPOP) {activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);activity.getWindow().setStatusBarColor(Color.TRANSPARENT);} else {activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);}ViewGroup contentLayout (ViewGroup) drawerLayout.getChildAt(0);View doraStatusBarView contentLayout.findViewById(DORA_STATUS_BAR_VIEW_ID);if (doraStatusBarView ! null) {if (doraStatusBarView.getVisibility() View.GONE) {doraStatusBarView.setVisibility(View.VISIBLE);}doraStatusBarView.setBackgroundColor(statusBarColor);} else {contentLayout.addView(createStatusBarView(activity, statusBarColor), 0);}if (!(contentLayout instanceof LinearLayout) contentLayout.getChildAt(1) ! null) {contentLayout.getChildAt(1).setPadding(contentLayout.getPaddingLeft(), getStatusBarHeight(activity) contentLayout.getPaddingTop(),contentLayout.getPaddingRight(), contentLayout.getPaddingBottom());}setFitsSystemWindow(drawerLayout, contentLayout);addStatusBarView(activity, statusBarAlpha);
}设置fitsSystemWindow
private static void setFitsSystemWindow(DrawerLayout drawerLayout, ViewGroup drawerLayoutContentLayout) {ViewGroup drawer (ViewGroup) drawerLayout.getChildAt(1);drawerLayout.setFitsSystemWindows(false);drawerLayoutContentLayout.setFitsSystemWindows(false);drawerLayoutContentLayout.setClipToPadding(true);drawer.setFitsSystemWindows(false);
}添加状态栏View
/*** 添加半透明矩形条。** param activity 需要设置的 activity* param statusBarAlpha 状态栏透明度*/
private static void addStatusBarView(Activity activity, IntRange(from 0, to 255) int statusBarAlpha) {ViewGroup contentView (ViewGroup) activity.findViewById(android.R.id.content);View doraStatusBarView contentView.findViewById(DORA_STATUS_BAR_VIEW_ID);if (doraStatusBarView ! null) {if (doraStatusBarView.getVisibility() View.GONE) {doraStatusBarView.setVisibility(View.VISIBLE);}doraStatusBarView.setBackgroundColor(Color.argb(statusBarAlpha, 0, 0, 0));} else {contentView.addView(createTranslucentStatusBarView(activity, statusBarAlpha));}
}
