Home键监听

编写广播接收器 private final BroadcastReceiver homePressReceiver = new BroadcastReceiver() { final String SYSTEM_DIALOG_REASON_KEY = "reason"; final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey"; @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if(action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) { String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY); if(reason != null && reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) { // 自己随意控制程序，关闭... } } }在onCreate中注册接收器
final IntentFilter homeFilter = new IntentFilter( Intent.ACTION_CLOSE_SYSTEM_DIALOGS); registerReceiver(homePressReceiver, homeFilter);在onDestory()中解除注册防止报错
if(homePressReceiver != null) { try { unregisterReceiver(homePressReceiver); } catch(Exception e) { } }
电源键监听

首先，我们是要获取系统权限
监听Action
// Intent.ACTION_SCREEN_OFF; // Intent.ACTION_SCREEN_ON; private final BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() { @Override public void onReceive(final Context context, final Intent intent) { final String action = intent.getAction(); if(Intent.ACTION_SCREEN_OFF.equals(action)) { } } };     // onCreate()方法中注册     IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_OFF);     registerReceiver(mBatInfoReceiver, filter);    // onDestory()方法中解除注册    if(mBatInfoReceiver != null) {        try {            unregisterReceiver(mBatInfoReceiver);        }        catch(Exception e) {       }    }
