package com.mythmayor.a1805statusbardemo;

import android.os.Build;

import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;

import android.view.View;

public class Status4Activity extends AppCompatActivity {

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_status4);

}

@Override

public void onWindowFocusChanged(boolean hasFocus) {

super.onWindowFocusChanged(hasFocus);

if (hasFocus && Build.VERSION.SDK_INT >= 19) {

View decorView = getWindow().getDecorView();

decorView.setSystemUiVisibility(

View.SYSTEM_UI_FLAG_LAYOUT_STABLE

| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION

| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION

| View.SYSTEM_UI_FLAG_FULLSCREEN

| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);

}

}

}

方式2.透明状态栏效果，需要在5.0及其以上系统才支持。

• 布局文件

xmlns:tools=“http://schemas.android.com/tools”

android:layout_width=“match_parent”

android:layout_height=“match_parent”

tools:context=“com.mythmayor.a1805statusbardemo.Status2Activity”>

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:scaleType=“centerCrop”

android:src="@mipmap/mythmayor_bg03" />

• Java代码

package com.mythmayor.a1805statusbardemo;

import android.graphics.Color;

import android.os.Build;

import android.os.Bundle;

import android.support.v7.app.ActionBar;

import android.support.v7.app.AppCompatActivity;

import android.view.View;

public class Status2Activity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_status2);

if (Build.VERSION.SDK_INT >= 21) {

View decorView = getWindow().getDecorView();

int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;

decorView.setSystemUiVisibility(option);

getWindow().setStatusBarColor(Color.TRANSPARENT);

}

ActionBar actionBar = getSupportActionBar();

actionBar.hide();

}

}

方式3.将状态栏和导航栏设置为透明

• Step1 在布局文件根布局中加入下面代码

android:fitsSystemWindows=“true”

• Step2 在Activity文件的setContent()方法之前加入下面代码

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

//透明状态栏

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

//透明导航栏

getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);

}

方式4.将状态栏和导航栏设置为透明

• Step1 在布局文件根布局中加入下面代码

android:fitsSystemWindows=“true”

• Step2 使用SystemBarTintManager和StatusBarUtil对状态栏进行设置

只需一行代码即可设置指定颜色的沉浸式状态栏

StatusBarUtil.initSystemBar(this, R.color.white);

下面附上代码 SystemBarTintManager.java
