关于屏幕解锁的实例

AndroidManifest.xml加两个权限

<uses-permission android:name="android.permission.DISABLE_KEYGUARD"></uses-permission>
<uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission>

Android屏幕解锁:
KeyguardManager keyguardManager = (KeyguardManager)getSystemService(KEYGUARD_SERVICE);
KeyguardLock keyguardLock = keyguardManager.newKeyguardLock("");
keyguardLock.disableKeyguard();
Android 点亮屏幕:
PowerManager pm = (PowerManager)getSystemService(POWER_SERVICE);
WakeLock mWakelock = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.SCREEN_DIM_WAKE_LOCK, "SimpleTimer");
mWakelock.acquire();
//...
mWakelock.release();//关闭

import android.app.KeyguardManager;
import android.content.Context;
import android.os.PowerManager;

public class ScreenLockManager {
private Context mContext;
private KeyguardManager.KeyguardLock mKeyguardLock;
private boolean isScreenLock;
private PowerManager.WakeLock mWakelock;
public ScreenLockManager(Context context) {
mContext = context;
}
public void getUnlock() {
// acquire wake lock
PowerManager pm = (PowerManager) mContext.getSystemService(Context.POWER_SERVICE);
mWakelock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "SimpleTimer");
mWakelock.acquire();
// unlock screen
KeyguardManager km = (KeyguardManager) mContext.getSystemService(Context.KEYGUARD_SERVICE);
mKeyguardLock = km.newKeyguardLock(Log.TAG);
if (km.inKeyguardRestrictedInputMode()) {
mKeyguardLock.disableKeyguard();
isScreenLock = true;
} else {
isScreenLock = false;
}
}
public void releaseUnlock() {
// release screen
if (isScreenLock) {
mKeyguardLock.reenableKeyguard();
isScreenLock = false;
}
// release wake lock
if (mWakelock.isHeld()) {
mWakelock.release();
}
}
------------
public class Log {
public static final String TAG = "SimpleTimer";
public static void v(String msg){
android.util.Log.v(TAG, msg);
}
public static void d(String msg){
android.util.Log.d(TAG, msg);
}
public static void e(String msg){
android.util.Log.e(TAG, msg);
}
public static void e(Exception e){
android.util.Log.e(TAG, e.getMessage(),e);
}
