Android APP透明化状态栏的方法

实现状态栏透明化

1.删除标题栏
2.导入Class

删除Activity自带的item

使要使用的活动继承自Activity即可完成

导入Class

package com.scxx.wangli_qq.UserControl;

import android.annotation.TargetApi;
import android.app.Activity;
import android.graphics.Color;
import android.os.Build;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;

public class Iucency_Bar {
    public static void setTransparent(Activity activity) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
            return;
        }
        transparentStatusBar(activity);
        setRootView(activity);
    }
    /**
     * 使状态栏透明
     */
    @TargetApi(Build.VERSION_CODES.KITKAT)
    private static void transparentStatusBar(Activity activity) {
        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);
            //需要设置这个flag contentView才能延伸到状态栏
            activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            //状态栏覆盖在contentView上面，设置透明使contentView的背景透出来
            activity.getWindow().setStatusBarColor(Color.TRANSPARENT);
        } else {
            //让contentView延伸到状态栏并且设置状态栏颜色透明
            activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }
    }

    /**
     * 设置根布局参数
     */
    private static void setRootView(Activity activity) {
        ViewGroup parent = (ViewGroup) activity.findViewById(android.R.id.content);
        for (int i = 0, count = parent.getChildCount(); i < count; i++) {
            View childView = parent.getChildAt(i);
            if (childView instanceof ViewGroup) {
                childView.setFitsSystemWindows(true);
                ((ViewGroup) childView).setClipToPadding(true);
            }
        }
    }
}

在onCreate方法中引用
