Android键盘自动弹出解决方法分析,android 键盘弹出

Android 键盘自动弹出解决方法分析,android 键盘弹出本文实例分析了android 键盘自动弹出解决方法。

分享给大家供大家参考，具体如下：1、在：复制代码代码如下:activity android:name=".uninstaller"android:label="@string/app_name" android:windowsoftinputmode="adjustpan"加入了：复制代码代码如下:android:windowsoftinputmode="adjustpan"就不会自动弹出软键盘了。

ps ：该方法可以把键盘隐藏掉，但界面不能滚动，即使布局中用了scrolllayout.2、就是将焦点转移到别的组件上，如转移到button 上[Java] 查看源文件复制代码?1 2 3 4 button.setfocusable(true);button.setfocusableintouchmode(true);button.requestfocus();button.requestfocusfromtouch();ps ：此方法靠谱。

3、edittext.clearfocus （这方法根本不行）alertdialog 自定义视图中的按钮，当点击时，想把alertdialog 隐藏掉，发现不可以，只能通过alertdialog 自带的三个按钮，将其消失掉。

[Java] 查看源文件复制代码?01 02 03 04 05 06 07 08 09 10 //带取消按钮的progressdialogdownloaddialog = new progressdialog(context);downloaddialog.setcancelable(false);//back 键不起作用,若为true,按back 键，则progres 失掉downloaddialog.setmessage("正在下载安装包...");downloaddialog.setbutton("取消", new dialoginterface.onclicklistener() {public void onclick(dialoginterface dialog, int i) {dialog.cancel();downapkcancel = true;}});。

安卓手机技巧之一——实现任意键唤醒屏幕教程

•安卓手机技巧之一——实现任意键唤醒屏幕教程
手机用久了某个按键有可能会坏，比如唤醒屏幕的电源按键，基本每天都会用到很多次。

时间久了肯定会用坏。

在这里，就教大家一种安卓手机修改任意键唤醒屏幕的方法。

采用搜索键和电源键互换的方式，前提是你的手机需要已经ROOT，然后安装一个常用的RE管理器即可，无需安装任何软件。

下面我们开始吧：
第一步：找到下图路径中的文件
同时将手机挂载为可读写
第二步：修改文件权限如下图
第三步：以文本编辑器打开此文件
第四步：未修改前红线部分为待修改
第五步：按照下图修改：
这个时候如果你需要别的按键唤醒屏幕，只需要在别的按键键值后面加上同样的修改第六步：保存退出
重启手机你就发现搜索键实现了唤醒屏幕
下面说说搜索键和电源键互换
前四步都是一样的只需要把键值修改为下图再重启手机即可实现
按照这样的方法也可以实现任意键唤醒屏幕的操作，只需要修改你想要用作唤醒屏幕的按键即可。

Multi-Touch 是 Eclair 版本的新特性。多点触摸的特性，需要从硬件到软件系统的支持。作为 Android 的 GUI 系统，最终的就是将消息从下传递到上面。输入设备中增加了一个新的类型： TOUCHSCREEN_MT （ EventHub.h 定义）， EventHub 获得信息只有交由 JAVA 层处理。
2.4 Android 的用户输入系统
android.view.RawInputEvent 增加多点数据表示， InputDevice 作处理，并保持对非多点触摸的兼容性， KeyInputQueue （ android/server/KeyInputQueue ）进行多点数据的转化。 MotionEvent 增加了对多点的支持，最多支持同时有 3 个点触摸。这是上层程序中用到的接口。注意：没有手势方面的解析，需要应用程序根据多点信息自己实现解释。

MIUI你会用吗那些容易遗忘的功能盘点

MIUI你会用吗那些容易遗忘的功能盘点试问小米手机在国内乃至全球为什么都有着十分强大的号召力，究其原因有太多太多，有人说是其超高的配置，有人说是其低廉的价格。

追根究底，小米手机正是凭借着自己成熟的MIUI系统和无敌的性价比赢得了消费者们的好评。

MIUI是基于Android 系统深度优化、定制、开发的第三方手机操作系统，是受手机发烧友欢迎的Android ROM，专为中国人习惯而设计，全面改进原生体验，几百项为中国用户进行的优化与功能设计，绝对能够体现出MIUI系统的霸气。

MIUI目前已经拥有国内外超过1000万的发烧友用户，遍布全球各大洲。

作为最有群众基础的一个ROM，MIUI展现的、诠释的是其他ROM所不能比拟的。

也正是因为MIUI涵盖的功能太多太多，也导致了许多新老用户会错失其中一些比较实用的功能。

今天笔者的任务就是要带领大家一起对MIUI中最容易被人忽略与遗忘的功能探个究竟，走过路过千万别错过哦。

如果在这其中有你所知道的，请千万别喷我啊，如果在这其中有笔者所遗漏的，那就敬请赐教啦。

桌面效果与冷暖屏显这个完全高自由度的MIUI为我们能够带来最直观的好处就是省去了安装第三方美化软件的麻烦。

对于看惯了程序列表页千篇一律翻页效果的用户，经常会安装一些第三方的桌面软件来实现多样化的屏幕切换效果。

MIUI中，我们可以非常便捷地来设置（待机界面下--菜单键--桌面设置），进入设置之后，我们看到这里有非常多的效果可选，基本上第三方桌面软件包含的效果，在这里我们都能够找到。

桌面效果设置桌面翻页效果展示除了切换这些五花八门的屏幕切换效果之外，用户还能够在这里对壁纸滚动类型进行修改。

笔者习惯选择“居中”，也就是说，桌面的壁纸不会根据用户左右横滑翻页而随着一起动。

关于这一点的设置上，那就是要看每个用户不同的习惯了。

同样，关于桌面图标的布局，有人喜欢紧凑一些，有人喜欢放松一些，这都不要紧，在布局设定中用户可以自由选择4x4或者4x5的排列。

安卓键位操作方法

安卓键位操作方法
在安卓设备上，您可以使用以下键位来执行一些常见的操作：
1. 返回键（Back）：退回上一个界面或关闭当前弹出窗口。

2. 主页键（Home）：返回主屏幕。

3. 菜单键（Menu）：打开当前应用程序或屏幕的菜单选项。

4. 多任务键（Recent Apps）：打开最近使用的应用程序列表，可以轻松切换到其他正在运行的应用。

5. 音量键（Volume）：调节系统音量。

在相机应用中，它还可以用来拍照或进行缩放。

6. 电源键（Power）：用来锁定/解锁屏幕、屏幕截图、重启设备等。

7. 来电键（Call）：接听或结束来电。

8. 挂断键（End Call）：结束通话。

此外，不同设备品牌和型号可能会有一些特定的键位操作方法，请参考您的设备说明书或在设备设置中查找相关信息。

安卓系统使用教程

安卓系统手机全面使用教程~~~~~~~~~~扫盲贴相信很多朋友在购买了安卓系统手机之后，都被这样那样的小问题困扰着·~~发此贴的目的就是为了解决题，如果写的不够好不够详细请大家提出来我再做补充。

这里我们以HTC G10 为例，那些比较细致的，比如安装电池，SIM卡，TF卡之类的内容，这里就略过了一：按键用途介绍HOME键，小房子-在任何程序或者界面内按此键可以立即回到待机主界面设置界面，MENU-打开设置菜单。

返回键，不用多做介绍了吧搜索键，同上。

安卓机器都差不多摸索下就可以。

二：设置篇。

1. 语言设置，这里以其他语言设置中文为例。

请看截图~~~~首先我们看到的是英文待机界面按MENU键调出设置菜单点击设置键菜单往下拉选择LANGUAGE选项选择第一项选择中文这样语言就设置好咯~~~2.网络设置--安装海卓APN软件设置如下图选择一键设置APN信息就行了，如果不行的话，打开手机设置-无线和网络设置-移动网络设置-数据漫游打开就以了。

如果某天你突然不能上网了建议重新设置下APN信息，最好重启下就可以上网了备注：安卓系统吸流量比较厉害，见过N个不到1个星期欠费500+的人了，都是流量费用，建议不上网的时关闭GPRS上网海卓内有开关的不用多说，当然也可以创建小插件到桌面上，后面会有说到。

3.输入法设置----这个在我第一次用安卓手机的时候也让我纠结了一下首先在91里下载安装自己比较喜欢的输入法，这里推荐搜狗和讯飞语音输入法，狗狗就是拼音，讯飞有拼语音，及手写输入。

安装好之后设置如下图进到设置选择语言和键盘勾选已安装的输入法进入到短信界面新建短信-长按文字输入窗口不松跳出输入法选项选择自己喜欢的输入法就可以了以后不需要重复选择。

4.桌面图标设置-可以把自己常用的图标拖放到桌面上以方便使用打开主程序菜单选择自己想要放在桌面的程序长按不松直接就出现在待机菜单上了放在自己喜欢的位置上就可以了在待机界面上长按程序图标不松拖到垃圾桶就可以删除该图标。

回归用户,聚焦个性四大主流手机系统功能体验(上)

2021年度重庆市出版专项资金资助项目关注“智范儿”，了解更多！回归用户，聚焦个性四大主流手机系统功能体验（上）在过去很长一段时间里，大家一提起iPhone，就会盛赞iOS系统的流畅性和丰富的功能。

可见除了硬件之外，系统也是用户选购手机品牌的重要因素之一。

在市场份额稳步上升后，国内厂商也越来越重视系统、软件层面的优化。

2020年，华为、OPPO、小米和vivo旗下的手机软件系统都进行过大刀阔斧的版本更新，它们不仅在设计方面各有亮点，还开发了不少或新奇或实用的功能。

这一次，我们就在4大品牌的主打旗舰机型上梳理新系统的特性，并教大家如何更好地使用这些功能。

文/图谢慧华于华为开发者大会2020上亮相的EMUI 11仍基于Android 10基础开发，但在上手之后你会发现，它带来了许多原生Android系统没有的特性，以人为本进行细节上的补充优化。

除此之外，EMUI 11融入了鸿蒙系统的分布式技术，更加强调畅联交互和隐私保护。

灵动视觉，便捷交互在保留EMUI 10的UI设计基础上，EMUI 11更强调连贯的动画效果。

在日常操作中，无论是锁屏、解锁，还是打开系统应用，我们可以明显感受到不同画面切换之间的衔接更加流畅。

设置中，EMUI 11提供了多套壁纸、主题，还加入了样式丰富的熄屏显示功能。

在熄屏状态下，用户可以在屏幕上看到时间、日期、短信和来电提醒等信息。

当我们触摸屏幕或系统检测到人眼注视时，手机就会进入人脸识别界面，快速解锁屏幕，省去了按压电源键的解锁步骤。

多任务操作一直是Android的优势，EMUI 11在此基础上加快了多任务处理的效率。

它将简单的分屏模式扩展为“分屏+悬浮窗口”模式，通过侧边应用栏实现快速切换。

用户在所有界面中都可以从屏幕左、右侧向内滑动打开侧边应用栏，长按快捷应用图标启用分屏模式，点击图标则以悬浮窗口显示。

和单一的分屏模式相比，EMUI 11的多任务处理可以同屏显示3个应用，分屏应用可以上下调节分屏大小，悬浮窗口则可以自由调节，并最小化地收入悬浮球中。

Android原生系统手动添加虚拟按键教程对于有实体按键的Android手机来说机友们总会担心哪天它会不会突然失灵。

又不想依赖第三方应用来添加虚拟按键怕拖慢手机运行速度。

那么用系统自带的总没问题了吧?相信作为官方控还是有很多同学都能够接受这样的方法。

接下来小编就告诉大家如何给手机添加虚拟按键，反之也可以用同样的方法来删除虚拟按键。

首先是要获取手机的root权限，然后打开“RE管理器”到系统根目录的System目录下，找到build.prop
这个文件里包含了很多设备的信息，我们在设置里看到的很多版本号都是来自这里
使用文本编辑的方式打开这个文件，在最后一行加入“qemu.hw.mainkeys=0”
重启以后，就会发现屏幕下方出现熟悉的虚拟键，另外这造型似乎和Sony 的虚拟键很类似…
小米2也有可以通过相同的方法调出虚拟键，如图所示
在设置的“按键”里面甚至还有虚拟键专用的调节菜单，可对四个虚拟键进行位置的调换，这不禁让人怀疑小米2的原型会不会就是带有虚拟键的
当然了，这种方法对于小屏幕手机来说会造成很大的影响，占用了一定的屏幕空间这个方法实际上对于一般用户来说可能用户都不大，不过利用同样的思路可以改变部分手机的虚拟键，例如较早期的One X(One S)就可以通过类似的方法去掉那“反人类”的菜单虚拟键
