如何使得锁屏界面显示充电和闹铃信息

如何使得锁屏界面显示充电和闹铃信息?
[SOLUTION]
Google default的design 是这个充电信息和闹钟信息是跟SIM卡绑定的，所以在双卡的情况下，需要同时插
入两张SIM卡，才会显示充电信息及闹钟信息的；如需要修改，请参考下面的代码：
在lockscreen.java修改：
private void updateStatusLines() {
/*if (！mStatus.showStatusLines()
|| (mCharging == null && mNextAlARM == null)) {
mStatus1.setVisibility(View.INVISIBLE);
mStatus2.setVisibility(View.INVISIBLE);
// }else if(FeatureOption.mtk_GEMINI_SUPPORT == true &&
！mStatusGemini.showStatusLines()){
else if(FeatureOption.MTK_GEMINI_SUPPORT == true ){
mStatus1.setVisibility(View.INVISIBLE);
mStatus2.setVisibility(View.INVISIBLE);
} else*/
=========================================================
//把上面的代码注释掉。
加上这样的判断：
加上(mCharging == null && mNextAlarm == null)的分支
=====================================================
if (mCharging ！= null && mNextAlarm == null) {
// charging only
mStatus1.setVisibility(View.VISIBLE);
mStatus2.setVisibility(View.INVISIBLE);
mStatus1.setText(mCharging);
mStatus1.setCompoundDrawablesWithIntrinsicBounds(mChargingIcon, null,
null, null);
} else if (mNextAlarm ！= null && mCharging == null) {
// next alarm only
mStatus1.setVisibility(View.VISIBLE);
mStatus2.setVisibility(View.INVISIBLE);
mStatus1.setText(mNextAlarm);
mStatus1.setCompoundDrawablesWithIntrinsicBounds(mAlarMICon, null, null,
null);
} else if (mCharging ！= null && mNextAlarm ！= null) {
// both charging and next alarm
mStatus1.setVisibility(View.VISIBLE);
mStatus2.setVisibility(View.VISIBLE);
mStatus1.setText(mCharging);
mStatus1.setCompoundDrawablesWithIntrinsicBounds(mChargingIcon, null,
null, null);
mStatus2.setText(mNextAlarm);
mStatus2.setCompoundDrawablesWithIntrinsicBounds(mAlarmIcon, null, null,
null);
}
}
