最近在使用自己手机,发现一种动画效果非常不错,就是天气随着时间季节,状态栏和ToorBar颜色都会发生改变,搜索资料得出的三种方案….
方案一
将手机状态栏透明化: 状态栏透明了,状态栏的颜色就会自动跟随下面的布局
两种方式:1.代码方式 /** * 设置透明状态栏 * <p> * 可在Activity的onCreat()中调用 * <p> * 注意:需在顶部控件布局中加入以下属性让内容出现在状态栏之下: * android:clipToPadding="true" // true 会贴近上层布局 ; false 与上层布局有一定间隙 * android:fitsSystemWindows="true" //true 会保留actionBar,title,虚拟键的空间 ; false 不保留 * * @param activity activity */ public static void setTransparentStatusBar(Activity activity) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { View decorView = activity.getWindow().getDecorView(); int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE; decorView.setSystemUiVisibility(option); activity.getWindow().setStatusBarColor(Color.TRANSPARENT); } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { WindowManager.LayoutParams localLayoutParams = activity.getWindow().getAttributes(); localLayoutParams.flags = (WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | localLayoutParams.flags); } } ---------------------分割线--------------------------2.在values,values-v19,values-v21目录下分别 创建主题<style name="TranslucentTheme" parent="AppTheme"></style><style name="TranslucentTheme" parent="Theme.AppCompat.Light.NoActionBar"> <item name="android:windowTranslucentStatus">true</item> <item name="android:windowTranslucentNavigation">false</item></style><style name="TranslucentTheme" parent="Theme.AppCompat.Light.NoActionBar"> <item name="android:windowTranslucentStatus">true</item> <item name="android:windowTranslucentNavigation">false</item> <item name="android:statusBarColor">@android:color/transparent</item></style>

方案二 (推荐)
嵌套布局,修改布局文件的根布局为状态栏着色,子步局用来指定页面的背景颜色
1.如方案一将状态栏透明化2.修改布局文件//善用 这两个属性//android:clipToPadding="true" // true 会贴近上层布局 ; false 与上层布局有一定间隙//android:fitsSystemWindows="true" //true 会保留actionBar,title,虚拟键的空间 ; false 不保留<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#ff9900" android:fitsSystemWindows="true"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:background="#ffffff" android:orientation="vertical"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="#f00000" android:theme="@style/AppTheme.AppBarOverlay" app:title="Text" /> </LinearLayout></RelativeLayout>

方案三
使用Android:fitsSystemWindows=”true”属性,给状态栏留出空间,添加一个和状态栏宽高相同的View覆盖透明的状态栏
一.如方案一将状态栏透明化二.指定状态栏高度,两种方式:1.代码获取状态栏高度: public static int getStatusBarHeight(Context context) { int result = 0; int resourceId = context.getResources() .getIdentifier("status_bar_height", "dimen", "android"); if (resourceId > 0) { result = context.getResources().getDimensionPixelSize(resourceId); } return result; }-------------------------分割线------------------------------2.在values,valuse-v19 目录下直接指定高度:(这种方式可能会因为设备分辨率不同,有稍微误差)<dimen name="padding_top">0dp</dimen><dimen name="padding_top">25dp</dimen>3.添加一个View覆盖状态栏 private void addStatusBarView() { View view = new View(this); view.setBackgroundColor(getResources().getColor(R.color.colorPrimary)); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(this)); ViewGroup decorView = (ViewGroup) findViewById(android.R.id.content); decorView.addView(view, params); }

封装的一个工具类:
注意使用上面强调的两个属性在布局中的使用
public class StatusBar { /** * 设置透明状态栏 * <p> * 可在Activity的onCreat()中调用 * <p> * 注意:需在顶部控件布局中加入以下属性让内容出现在状态栏之下: * android:clipToPadding="true" // true 会贴近上层布局 ; false 与上层布局有一定间隙 * android:fitsSystemWindows="true" //true 会保留actionBar,title,虚拟键的空间 ; false 不保留 * * @param activity activity */ public static void setTransparentStatusBar(Activity activity) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { View decorView = activity.getWindow().getDecorView(); int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE; decorView.setSystemUiVisibility(option); activity.getWindow().setStatusBarColor(Color.TRANSPARENT); /** * 如果上面无效,用这个 *activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); *activity.getWindow().setStatusBarColor(Color.TRANSPARENT); */ } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { WindowManager.LayoutParams localLayoutParams = activity.getWindow().getAttributes(); localLayoutParams.flags = (WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | localLayoutParams.flags); /** * 如果上面无效,用这个 * activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); */ } } /** * 获取状态栏高度 * * @param context 上下文 * @return 状态栏高度 */ public static int getStatusBarHeight(Context context) { int result = 0; int resourceId = context.getResources() .getIdentifier("status_bar_height", "dimen", "android"); if (resourceId > 0) { result = context.getResources().getDimensionPixelSize(resourceId); } return result; } /** * 判断状态栏是否存在 * * @param activity activity * @return true :存在 ; false: 不存在 */ public static boolean isStatusBarExists(Activity activity) { WindowManager.LayoutParams params = activity.getWindow().getAttributes(); return (params.flags & WindowManager.LayoutParams.FLAG_FULLSCREEN) != WindowManager.LayoutParams .FLAG_FULLSCREEN; } /** * 添加状态栏View * * @param activity 需要设置的 activity * @param argb Color.argb(alpha, 0, 0, 0) 颜色属性 */ private static void addStatusBarView(Activity activity, int argb) { ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content); if (contentView.getChildCount() > 1) { contentView.removeViewAt(1); } contentView.addView(createStatusBarView(activity, argb)); } /** * 创建矩形 View * * @param argb Color.argb(alpha, 0, 0, 0) 颜色属性 * @return View */ private static View createStatusBarView(Activity activity, int argb) { View statusBarView = new View(activity); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(activity)); statusBarView.setLayoutParams(params); statusBarView.setBackgroundColor(argb); return statusBarView; }}
