Android SystemUI 信号栏后添加信号图标

SystemUI自定义的状态栏信号view

frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\SignalClusterView.java

所在的自定义的布局

frameworks\base\packages\SystemUI\res\layout\

其中一个

gemini_signal_cluster_view.xml

signal_cluster_view.xml//9200B

 

添加图标或者文字在信号栏后面

     android:id="@+id/mobile_slot_indicator_4"

               android:layout_height="wrap_content"

               android:layout_width="wrap_content"

               android:layout_marginStart="1dp"

                android:visibility="gone"

               android:tag="mobile_slot_indicator_4"

                />

       

 

                         

                      

           android:id="@+id/custom_signal_4g"        

           android:layout_height="wrap_content"

           android:layout_width="wrap_content"

                     android:visibility="gone"

           android:background="@drawable/stat_sys_gemini_signal_4g_blue"          

           />

 

            android:id="@+id/custom_signal_volte"           

           android:layout_height="wrap_content"

           android:layout_width="wrap_content"

                     android:layout_marginLeft="3dp"

                     android:visibility="gone"

           android:background="@drawable/stat_sys_volte"          

           />

            

   

 

 private ImageView custom_signal_4g;

   private ImageView custom_signal_volte;

   @Override

    protected voidonAttachedToWindow() {

       super.onAttachedToWindow();

       //add 4g state lhw start  初始化控件

               custom_signal_4g  = (ImageView)findViewById(R.id.custom_signal_4g);

                custom_signal_volte = (ImageView)findViewById(R.id.custom_signal_volte);

 

进行信号栏状态跟随当前信号状态变化显示,无信号时做判断

if (mMobileStrengthId[i][0].getIconId() ==PluginFactory.getStatusBarPlugin(mContext).getSignalStrengthNullIconGemini(i)

                    ||mMobileStrengthId[i][0].getIconId() == 0 || mMobileStrengthId[i][0].getIconId()== R.drawable.stat_sys_gemini_signal_null) {//找到无信号地方进行操作

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

                                     //show custom network state lhw start

                                          custom_signal_4g.setVisibility(View.GONE);           

                             custom_signal_volte.setVisibility(View.GONE);  

  }

                            //showcustom network state lhw start

                                          else{

                                          custom_signal_4g.setVisibility(View.VISIBLE);           

                             custom_signal_volte.setVisibility(View.VISIBLE);  

                                         

                                   }

                            //showcustom network state lhw end

 

隐藏手机带的信号

SystemUI\src\com\android\systemui\statusbar\policy\TelephonyIcons.java

//这里显示的是信号状态条上的网络状态标志3g/4g/2g等替换资源图片为空白

static final int[] DATA_G= {

static final int[]DATA_3G = {

static final int[] DATA_E= {

 

//这里显示的是信号状态前面的的大的网络状态标志3G/4G/2G等

 

static final int[]NETWORK_TYPE_G = {

static final int[]NETWORK_TYPE_3G = {

static final int[]NETWORK_TYPE_4G = {

 

static public int getNetworkTypeIconGemini(NetworkTypenetworkType, int simColorId) {

      

if (networkType == NetworkType.Type_G) {

     

           // return NETWORK_TYPE_G[simColorId];

        return  0; //修改为 0 让其函数对外无显示

                  

       } else if (networkType == NetworkType.Type_3G) {

           return NETWORK_TYPE_3G[simColorId];

       } else if (networkType == NetworkType.Type_4G) {

           return NETWORK_TYPE_4G[simColorId];

       } else {

           return -1;

       }
