import android.annotation.TargetApi;import android.app.Activity;import android.content.Context;import android.graphics.Color;import android.os.Build;import android.view.View;import android.view.ViewGroup;/** * Created by zhy on 15/9/21. */public class StatusBarCompat{    private static final int INVALID_VAL = -1;    private static final int COLOR_DEFAULT = Color.parseColor("#20000000");    @TargetApi(Build.VERSION_CODES.LOLLIPOP)    public static void compat(Activity activity, int statusColor)    {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)        {            if (statusColor != INVALID_VAL)            {                activity.getWindow().setStatusBarColor(statusColor);            }            return;        }        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)        {            int color = COLOR_DEFAULT;            ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content);            if (statusColor != INVALID_VAL)            {                color = statusColor;            }            View statusBarView = new View(activity);            ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,                    getStatusBarHeight(activity));            statusBarView.setBackgroundColor(color);            contentView.addView(statusBarView, lp);        }    }    public static void compat(Activity activity)    {        compat(activity, INVALID_VAL);    }    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;    }}

用法:

Activiy onCreate中添加：
StatusBarCompat.compat(this);

如果需要制定状态栏颜色,使用此方法：
StatusBarCompat.compat(this, 0xFFFF0000);
