1.屏蔽back键：
public boolean onKeyDown(int keyCode ,KeyEvent event){
if(event.getKeyCode() == KeyEvent.KEYCODE_BACK)
return true ;
else
return super.onKeyDown(keyCode, event);
}
2.屏蔽home键（需要api5以上）：
@Override
public void onAttachedToWindow() {
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);
super.onAttachedToWindow();
}
6.防止接听电话时锁屏：
oncreate中调用：
TelephonyManager mTelephonyMgr = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
mTelephonyMgr.listen(new TeleListener(),PhoneStateListener.LISTEN_CALL_STATE);
class TeleListener extends PhoneStateListener{
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
//空闲
case TelephonyManager.CALL_STATE_IDLE: {
break;
}
//接通
case TelephonyManager.CALL_STATE_OFFHOOK: {
finish();
break;
}
//振铃
case TelephonyManager.CALL_STATE_RINGING: {
finish();
break;
}
default:
break;
}
}
}
7.开机自启动：
<receiver android:name=".OpenMbBcReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
