Android 监听锁屏、解锁、开屏监听锁屏、解锁、开屏 功能代码功能代码
主要介绍了Android 监听锁屏、解锁、开屏 功能代码的相关资料,需要的朋友可以参考下
1、首先定义、首先定义 ScreenListener
package com.app.lib;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.PowerManager;
/**
* Created by ${zyj} on 2016/6/21.
*/
public class ScreenListener {
private Context mContext;
private ScreenBroadcastReceiver mScreenReceiver;
private ScreenStateListener mScreenStateListener;
public ScreenListener(Context context) {
mContext = context;
mScreenReceiver = new ScreenBroadcastReceiver();
}
/**
* screen状态广播接收者
*/
private class ScreenBroadcastReceiver extends BroadcastReceiver {
private String action = null;
@Override
public void onReceive(Context context, Intent intent) {
action = intent.getAction();
if (Intent.ACTION_SCREEN_ON.equals(action)) { // 开屏
mScreenStateListener.onScreenOn();
} else if (Intent.ACTION_SCREEN_OFF.equals(action)) { // 锁屏
mScreenStateListener.onScreenOff();
} else if (Intent.ACTION_USER_PRESENT.equals(action)) { // 解锁
mScreenStateListener.onUserPresent();
}
}
}
/**
* 开始监听screen状态
*
* @param listener
*/
public void begin(ScreenStateListener listener) {
mScreenStateListener = listener;
registerListener();
getScreenState();
}
/**
* 获取screen状态
*/
private void getScreenState() {
PowerManager manager = (PowerManager) mContext
.getSystemService(Context.POWER_SERVICE);
if (manager.isScreenOn()) {
if (mScreenStateListener != null) {
mScreenStateListener.onScreenOn();
}
} else {
if (mScreenStateListener != null) {
mScreenStateListener.onScreenOff();
}
}
}
/**
* 停止screen状态监听
*/
public void unregisterListener() {
mContext.unregisterReceiver(mScreenReceiver);
}
/**
* 启动screen状态广播接收器
*/
private void registerListener() {
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
