android系统下,想实现软件关机功能.
android系统下，系统关机不方便。
想实现软件关机功能. 请问这样的应用如何写?
软件关机应用图标显示在任务栏上.
[解决办法]
其实代码挺简单的，麻烦的是需要编译才能正常运行：
main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button android:id="@+id/btn_shutdown"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/shutdown" />
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.demo"
android:sharedUserId="android.uid.system"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.SHUTDOWN"/>
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".ShutdownDemoActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
package com.android.demo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class ShutdownDemoActivity extends Activity {
private Button mButton;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mButton = (Button) findViewById(R.id.btn_shutdown);
mButton.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v) {
Intent newIntent = new Intent(Intent.ACTION_REQUEST_SHUTDOWN);
newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(newIntent);
}
});
}
}
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_PACKAGE_NAME := ShutdownDemo
LOCAL_CERTIFICATE := platform
include $(BUILD_PACKAGE)
# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))
