如何从应用程序更改启动器图标及其标签 [英] How to change launcher icon and it's label from the application

问题描述

如何在Android应用程序运行时中更改启动器图标及其标签?(如果可能)
我的意思是在 AndroidManifest.xml 中定义的属性: android:icon 和 android:label .我想用我从相机拍摄的图像代替它.

How can I change the launcher icon and its label from my application runtime in Android? (if it is possible)
I mean the properties defined in AndroidManifest.xml: android:icon and android:label. I want to replace it by the image I take from the camera.

推荐答案

编辑:您最初的答案未指定您要在运行时执行此操作.这行下面是编译之前的操作方法.至于在运行时以编程方式进行操作:

your original answer didn't specify you wanted to do it at runtime. Below the line is how to do it before it compiles. As for doing it programmatically at runtime:

来自此答案:

除非通过软件升级，否则您不能在签名和密封的APK中更改清单或资源.

You cannot change the manifest or the resource in the signed-and-sealed APK, except through a software upgrade.

但是，被接受的答案也指出了骇客"或某种作弊方式(我想).我还没有测试过，但是有一个消息源可供您查看.

But also, the accepted answer figured out a "hack" or some cheating way to do it (I presume). I haven't tested it, but there is a source for you to check out.

或者，此链接显然描述了如何使用小工具"方法.

Or, this link apparently describes how to do this using the "widget" approach.

所以可以说您的清单是这样的:

So lets say your manifest was like this:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="yourPackage"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

     ...

您可以通过将图像放入可绘制文件夹中来更改启动器图标:

You would change the launcher icon by putting images into your drawable folders:

Project folder --> res --> all the drawables

然后，您将 android:icon ="@ drawable/ic_launcher" 更改为 android:icon ="@ drawable/whateverTheNameOfTheImageIsYouPutInTheDrawablesFolders"

要更改标签:

打开位于以下位置的 strings.xml 文件:

Open up your strings.xml file which is located:

Project folder --> res --> values --> strings.xml

并查找如下所示的字符串:

And look for the string that looks like this:

<string name="app_name">Your App Name</string>

然后只需将您的应用名称更改为您想要的标签名称即可.

And just change Your App Name to be whatever you want the label to be.

摘要:

android:icon ="@ drawable/ic_launcher" 确定启动器图标，因此只需将图像添加到可绘制文件夹中，然后将 ic_launcher 更改为图像名称即可您想成为图标.

android:icon="@drawable/ic_launcher" determines your launcher icon, so just add images to the drawable folders and change ic_launcher to whatever the name of image is that you want to be the icon.

android:label ="@ string/app_name" 确定您的标签"，因此只需查找 app_name (因为标签引用了 @ string/app_name )添加到您的 strings.xml 文件中，然后更改 app_name 的内容.

android:label="@string/app_name" determines your "label" so just look for app_name (because the label is referenced to @string/app_name) in your strings.xml file and change the contents of app_name.
