KK上默认是显示1,2卡标识的。

如果隐藏它们，在文件SignalClusterView.java上由mMobileSlotIndicator变量控制

将mMobileSlotIndicator出现的地方屏蔽掉就可以 

2、如何去掉状态栏G、3G图标

去掉方法很简单，就是把这个View隐藏就行了，具体修改如下
SignalClusterView.java (frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar)

apply():

……

//hide network icon  begin       

/* int state = SIMHelper.getSimIndicatorStateGemini(i);//hide network icon

                if (!mIsAirplaneMode

                        && SIMHelper.isSimInserted(i)

                        && PhoneConstants.SIM_INDICATOR_LOCKED != state

                        && PhoneConstants.SIM_INDICATOR_SEARCHING != state

                        && PhoneConstants.SIM_INDICATOR_INVALID != state

                        && PhoneConstants.SIM_INDICATOR_RADIOOFF != state) {

                    ……

                } else {*/

                    mSignalNetworkType[i].setImageDrawable(null);

                    mSignalNetworkType[i].setVisibility(View.GONE);

                //}

    //hide network icon  end     

   ……

二 L版本上（5.0）如何增加有SIM卡1,2标记

L版本5.0默认是没有显示的1.2卡标识的！

如果要增加1,2标识，可按下面步骤添加：

   
1、Signal_Cluster_View.xml

<!-- M: Support "Default SIM Indicator". }@ -->
<LinearLayout
android:id="@+id/signal_cluster_combo"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
>
<View
android:layout_height="6dp"
android:layout_width="6dp"
android:visibility="invisible"
/>
<!-- M: Support "Service Network Type on Statusbar". @{ -->
<ImageView
android:id="@+id/network_type"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:visibility="gone"
/>
<!-- M: Support "Service Network Type on Statusbar". }@ -->
<FrameLayout
android:id="@+id/mobile_combo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<ImageView
android:id="@+id/mobile_signal"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
/>
<ImageView
android:id="@+id/mobile_type"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
/>
<!-- add :mobile_slot_indicateor". }@ -->
<ImageView
android:id="@+id/mobile_slot_indicator"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
/> 

</FrameLayout>
</LinearLayout>

<!-- the 2nd sim card start -->
<View
android:layout_height="1dp"
android:layout_width="1dp"
android:tag="spacer_2"
android:visibility="gone"
android:id="@+id/spacer_2"
/>
<View
android:layout_height="1dp"
android:layout_width="1dp"
android:visibility="invisible"
/>
<LinearLayout
android:id="@+id/signal_cluster_combo_2"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:tag="signal_cluster_combo_2"
>
<!-- M: Support "Service Network Type on Statusbar". @{ -->
<ImageView
android:id="@+id/network_type_2"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:visibility="gone"
android:tag="network_type_2"
/>
<!-- M: Support "Service Network Type on Statusbar". }@ -->
<FrameLayout
android:id="@+id/mobile_combo_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:tag="mobile_combo_2"
>
<ImageView
android:id="@+id/mobile_signal_2"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:tag="mobile_signal_2"
/>
<ImageView
android:id="@+id/mobile_type_2"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:tag="mobile_type_2"
/>
<!-- add :mobile_slot_indicateor". }@ -->
<ImageView
android:id="@+id/mobile_slot_indicator_2"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
/> 

</FrameLayout>
</LinearLayout>
<!-- the 2nd sim card end -->

2、SignalClusterView.java
文件添加

// add

private ImageView[] mMobileSlotIndicator;

//add
int[] slots_indicators=new int[]{R.drawable.sim1_indicator,R.drawable.sim2_indicator};
// 图片sim1_indicator，sim2_indicator是你制作的sim1,sim2标识


public SignalClusterView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
mSlotCount = SIMHelper.getSlotCount();
........
// add
mMobileSlotIndicator= new ImageView[mSlotCount];

}

onAttachedToWindow()那里
//add
for (int i = SIMHelper.SLOT_INDEX_DEFAULT ; i < mSlotCount; i++) {
final int k = i + 1;
if (i == SIMHelper.SLOT_INDEX_DEFAULT) {
// load views for first SIM card


mMobile[i] = (ImageView) findViewById(R.id.mobile_signal);
mMobileGroup[i] = (ViewGroup) findViewById(R.id.mobile_combo);
mMobileType[i] = (ImageView) findViewById(R.id.mobile_type);
mSpacer[i] = findViewById(R.id.spacer);
mSignalClusterCombo[i] = (ViewGroup) findViewById(R.id.signal_cluster_combo);
/// M: Support "Service Network Type on Statusbar"
mSignalNetworkType[i] = (ImageView) findViewById(R.id.network_type);

//tdp add
mMobileSlotIndicator[i] = (ImageView) findViewById(R.id.mobile_slot_indicator);
} else {
mMobile[i] = (ImageView) findViewWithTag("mobile_signal_" + k);
mMobileGroup[i] = (ViewGroup) findViewWithTag("mobile_combo_" + k);
mMobileType[i] = (ImageView) findViewWithTag("mobile_type_" + k);
mSpacer[i] = findViewWithTag("spacer_" + k);
mSignalClusterCombo[i] = (ViewGroup) findViewWithTag("signal_cluster_combo_" + k);
/// M: Support "Service Network Type on Statusbar"
mSignalNetworkType[i] = (ImageView) findViewWithTag("network_type_" + k);

//tdp add
mMobileSlotIndicator[i] = (ImageView) findViewWithTag("mobile_slot_indicator_"+k);
}

//add
mMobileSlotIndicator[i].setImageDrawable(slots_indicators[i]);
mMobileSlotIndicator[i].setVisibility(View.VISIBLE);
}

onDetachedFromWindow（）那里
//add 
@Override
protected void onDetachedFromWindow() {
mVpn = null;
mWifiGroup = null;
mWifi = null;
/// M: WifiActivityIcon
mWifiActivity = null;

for (int i = SIMHelper.SLOT_INDEX_DEFAULT; i < mSlotCount ; i++) {
mMobileGroup[i] = null;
mMobile[i] = null;
mMobileType[i] = null;
mSpacer[i] = null;
//add
mMobileSlotIndicator[i] = null;
}
