android intent.action_screen_on,android – ACTION_SCREEN_ON和ACTION_SCREEN_OFF不工作？

我正在尝试在屏幕关闭(锁定)时关闭WiFi,并在屏幕开启(解锁)时再次打开它.

我做了一个BroadcastReceiver;放入清单这段代码：

这是MyIntentReceiver类：

package org.androidpeople.boot;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

public class MyIntentReceiver extends BroadcastReceiver {

// Called when boot completes

public static boolean startup;

@Override

public void onReceive(Context context, Intent intent) {

// Set what activity should launch after boot completes

System.out.println("Intent Action: " + intent.getAction());

if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {

System.out.println("locked : ACTION_SCREEN_OFF");

} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {

System.out.println("not locked : ACTION_SCREEN_ON ");

} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {

System.out.println("User Unlocking it ");

}

else if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {

// this to indicate that program is running

// automaticlly not manually by user

startup = true;

System.out.println("Automatic BOOT at StartUp");

Intent startupBootIntent = new Intent(context, LaunchActivity.class);

startupBootIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

context.startActivity(startupBootIntent);

}

}

}

结果是 – 都是ACTION_SCREEN_ON

和ACTION_SCREEN_OFF永远不会被解雇！

USER_PRESENT和BOOT_COMPLETED工作正常,但另一个没有.我正在使用模拟器,而不是真正的设备 – 这会导致问题吗？

有帮助吗？

我需要打开和关闭屏幕才能启用/禁用WiFi

节省电池.
