android powerkey触发小应用总结

来源：互联网发布：网络上口口是什么意思编辑：程序博客网时间：2024/06/07 12:20

近日，做了一个长按powerkey触发dialog然后包含“关机”,"重启"，“飞行模式”三个button功能的应用。现将该应用的主文件做一下记录，方便日后查阅：

AndroidManifest.xml代码片：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.heimi.power"
android:sharedUserId="android.uid.system"
android:versionCode="1"

布局文件main.xml如下：

进入休眠模式的旋转动画布局loading_layout.xml如下：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:visibility="gone"
android:layout_height="match_parent"

<ImageView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:contentDescription="@null"
android:src="@drawable/center" />

<ImageView

android:layout_height="wrap_content"
android:layout_centerHorizontal="true"

<TextView

</RelativeLayout>

O(∩_∩)O~，。。。。先告一段落，未完待续！
