Android狀態欄着色工具類

簡述：

    最近在搭建一個基本的Android框架，所以用到了狀態欄着色，我們知道Android4.4開始已經可以改變手機狀態欄顏色了，那麼今天分享一組狀態欄改變顏色的工具類。

StatusBarCompat:

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().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
                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 = contentView.getChildAt(0);
            //改變顏色時避免重複添加statusBarView
            if (statusBarView != null && statusBarView.getMeasuredHeight() == getStatusBarHeight(activity)) {
                statusBarView.setBackgroundColor(color);
                return;
            }
            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;
    }
}

使用：

StatusBarCompat.compat(this, Color.parseColor("#000000"));
