android 沉浸式状态栏

沉浸式状态栏兼容4.4版本 4.4以下暂时无法实现

1、原来刚刚开始开发的时候，我搞这个沉浸式状态栏搞了很久，一直网上找资料，花了很长的时间才搞定，而且还一大堆问题，不多说 下面上代码

package com.example.chao.myview.view.viewI1;

import android.app.Activity;
import android.content.res.Resources;
import android.graphics.Color;
import android.os.Build;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;

import static android.view.View.SYSTEM_UI_FLAG_FULLSCREEN;
import static android.view.View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;
import static android.view.View.SYSTEM_UI_FLAG_LOW_PROFILE;

public class StatusbarUtil  {
    /**
     * 设置颜色
     * @param activity
     * @param color
     */
    public static void setStatusBarColor(Activity activity,int color){

        //5.0
        if (Build.VERSION.SDK_INT >=Build.VERSION_CODES.LOLLIPOP){

            activity.getWindow().setStatusBarColor(color);

        }else if (Build.VERSION.SDK_INT >=Build.VERSION_CODES.KITKAT){

            activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

            View view = new View(activity);

            view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,getStatusBarHeight(activity)));

            view.setBackgroundColor(color);

            ViewGroup decorView = (ViewGroup) activity.getWindow().getDecorView();

            decorView.addView(view);

            ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content);

            contentView.setPadding(0,getStatusBarHeight(activity),0,0);

        }
    }

    /**
     * 获取状态栏高度
     * @param activity
     * @return 状态栏高度
     */
    public static int getStatusBarHeight(Activity activity) {
        Resources resources = activity.getResources();
        //status_bar_height 这是状态栏资源名就能拿到高度
        return resources.getDimensionPixelOffset(resources.getIdentifier("status_bar_height", "dimen", "android"));
    }

    /**
     * 设置Activity全屏

     */
    public static void setActivityTranslucent(Activity activity){
        if (Build.VERSION.SDK_INT >=Build.VERSION_CODES.LOLLIPOP){

            ViewGroup decorView  = (ViewGroup) activity.getWindow().getDecorView();
            decorView.setSystemUiVisibility(SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
            activity.getWindow().setStatusBarColor(Color.TRANSPARENT);
        }else if (Build.VERSION.SDK_INT >=Build.VERSION_CODES.KITKAT){

            activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

        }
    }
}
