更改 Android Studio 中的默认 LAUNCHER 活动
[英]Changing the default LAUNCHER activity in Android Studio
问题描述
我想在主要活动进入之前有一个闪屏，但我的“主要活动”被自动设置为启动器。 我在堆栈溢出帖子和谷歌上搜索了很多，但找不到适合我的案例的解决方案。 下面我发布了我的 manifest.xml 文件，是的，我知道它很糟糕（我尝试了一些东西）。
更新：我根据评论中的建议更新了下面的 manifest.xml 文件，并尝试解决了在与另一位开发人员测试应用程序期间出现的以下问题：
应用程序启动，启动画面的背景图像加载，然后应用程序崩溃并关闭（有时甚至整个 AVD/电话）
这是我遇到的两个错误（！无论我尝试什么，FunFactsActivity.DEAD 都会不断发生）。

如下删除intent-filter标签，我认为它会起作用
<activity android:name=".FunFactsActivity"></activity>
解决方案2
1 2017-11-09 04:19:18
你只需要删除<intent-filter ...> ..... </intent-filter>然后你的 AndroidManifest.xml 看起来像
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.spdesigns.funfacts">
<application
android:name=".FunFactsApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".FunFactsActivity">
</activity>
<activity android:name=".SplashScreenActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
我希望这能帮到您。

如果您想先启动启动画面，请在您的清单文件中进行此更改
<application
android:name=".FunFactsApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".FunFactsActivity">
</activity>
<activity android:name=".SplashScreenActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>

在您的 manifest.xml 文件中，只有启动器活动应该有如下标签
<activity android:name=".SplashScreenActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
所有其他活动应如下所示..
<activity
android:name=".ActivityOne/>
<activity
android:name=".ActivityTwo"/>
<activity
android:name=".ActivityN"/>
现在假设如果您想稍后将 ActivityOne 作为启动器活动，那么只需将 ActivityOne 和 SplashScreenActivity 相互交换即可。

我使用以下 AndroidManifest.xml 创建了一个示例项目：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.spdesigns.funfacts">
<application
android:name=".FunFactsApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".FunFactsActivity">
<intent-filter>
<action android:name="android.intent.action.FunFactsActivity" />
<category android:name="android.intent.category.FunFactsActivity" />
</intent-filter>
</activity>
<activity android:name=".SplashScreenActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<!-- This is needed if you want to launch the splash screen without knowing the default main -->
<!-- you can call it with: -->
<!-- Intent intent = new Intent("com.spdesigns.funfacts.LaunchSplash") -->
<!-- context.startActivity(intent); -->
<intent-filter>
<action android:name="com.spdesigns.funfacts.LaunchSplash"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
</manifest>
启动画面用作启动器活动。 因此，您的代码中的其他地方可能存在问题。
解决方案6

干得好..
- 将您的启动图像复制到可绘制文件夹下。
- 在 drawable 文件夹下创建 background.xml。 使用下面的代码。 创建
<layer-list>项目。 在图层列表下添加以下代码。
<item android:drawable="@color/colorPrimaryDark"/>
<item>
<bitmap android:src="@drawable/splash"
android:gravity="center"></bitmap>
</item>
3.编辑你的style.xml。 在您的样式下添加下面的样式标签。
`<style name="SplashScreenTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">@drawable/background</item>
</style>`
4.创建一个扩展到AppCompatActivity的SplashActivity.java。 修改您的 onCreate 方法，如下所示。
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent(this,MainActivity.class);
startActivity(intent);
finish();
}
5. 创建一个名为 ClockTimer 的活动，它将扩展到应用程序。 修改 onCreate 如下。
@Override
public void onCreate() {
super.onCreate();
SystemClock.sleep(2000);
}
6.最后你需要修改你的androidmanifest文件。 在android清单文件中做以下更改。
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.vishal.golevr.splashscreenapp">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme"
android:name=".ClockTime">
<activity android:name=".SplashActivity" android:theme="@style/SplashScreenTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity"/>
</application>
</manifest>
您的输出将如下所示 .
解决方案7

如果您想先启动启动画面，请在您的清单文件中进行此更改
<application
android:largeHeap="true" // for large memory use
android:name=".FunFactsApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".FunFactsActivity">
</activity>
<activity android:name=".SplashScreenActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
你有两个选择
- 要减小您正在使用的图像的大小，请将图像大小压缩到 500kB 或更少。 或
2.然后将此添加到您的清单文件中，因为根据您的错误，您使用的是大尺寸图像，而 android 无法读取该图像，因此您的应用程序因内存不足而崩溃。
android:largeHeap="true"
