高通通话中，按电源键灭屏不锁屏处理：
在InCallPresenter.java ==>onCallListChange(CallList callList)方法{
if (isActivityStarted()) {
final boolean hasCall = callList.getActiveOrBackgroundCall() != null ||
callList.getOutgoingCall() != null;
mInCallActivity.dismissKeyguard(hasCall);/*****这个地方dismissKeyguard的*////
}
判断当前手机是不是锁屏的：
if (mKeyguardManager.inKeyguardRestrictedInputMode())
解锁和释放锁：
public void makeKeyguardLock(Context context,int i) {
KeyguardManager mManager = (KeyguardManager)context.getSystemService(context.KEYGUARD_SERVICE);
KeyguardManager.KeyguardLock mKeyguardLock = mManager.newKeyguardLock("Lock");
switch(i) {
case 1:
System.out.println("csh makeKeyguardLock disableKeyguard");
mKeyguardLock.disableKeyguard();
break;
case 2:
System.out.println("csh makeKeyguardLock reenableKeyguard");
mKeyguardLock.reenableKeyguard();
break;
default: break;
}
}
手机是否处于锁屏状态：
import android.app.KeyguardManager;
KeyguardManager mKeyguardManager = (KeyguardManager)context.getSystemService(context.KEYGUARD_SERVICE);
if (mKeyguardManager.inKeyguardRestrictedInputMode())

在锁屏之上弹出Toast.makeText消息：

调用：
