Android(安卓)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;

}
