以前写过类似下面那种：
图片填充顶部状态栏，直接说方法吧
1.创建一个状态栏的工具类：
public class StatusBarUtil { public static final int DEFAULT_STATUS_BAR_ALPHA = 112; /** * 设置状态栏颜色 * * @param activity 需要设置的 activity * @param color 状态栏颜色值 */ public static void setColor(Activity activity, int color) { setColor(activity, color, DEFAULT_STATUS_BAR_ALPHA); } /** * 设置状态栏颜色 * * @param activity 需要设置的activity * @param color 状态栏颜色值 * @param statusBarAlpha 状态栏透明度 */ public static void setColor(Activity activity, int color, int statusBarAlpha) { 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(calculateStatusColor(color, statusBarAlpha)); } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); // 生成一个状态栏大小的矩形 View statusView = createStatusBarView(activity, color, statusBarAlpha); // 添加 statusView 到布局中 ViewGroup decorView = (ViewGroup) activity.getWindow().getDecorView(); decorView.addView(statusView); setRootView(activity); } } /** * 设置状态栏纯色 不加半透明效果 * * @param activity 需要设置的 activity * @param color 状态栏颜色值 */ public static void setColorNoTranslucent(Activity activity, int color) { setColor(activity, color, 0); } /** * 设置状态栏颜色(5.0以下无半透明效果,不建议使用) * * @param activity 需要设置的 activity * @param color 状态栏颜色值 */ public static void setColorDiff(Activity activity, int color) { if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) { return;

} public static void setImgTransparent(Activity activity){ if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { Window window = activity.getWindow(); window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_STABLE); window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); window.setStatusBarColor(Color.TRANSPARENT); window.setNavigationBarColor(Color.TRANSPARENT); } }}2.在ActivityonCreate()方法中，一定要在setContentView()之前添加：
getWindow().requestFeature(Window.FEATURE_NO_TITLE);StatusBarUtil.setImgTransparent(this);这样就可以实现了！
