Android Status bar添加耳机图标

1. 将耳机资源图片文件stat_sys_headset.png放到android/frameworks/base/packages/SystemUI/res/drawable-nodpi/

2. 修改android/frameworks/base/core/res/res/values/config.xml

<string-array name="config_statusBarIcons">
<item><xliff:g id="id">ime</xliff:g></item>
<item><xliff:g id="id">volume</xliff:g></item>
<span style="color:#3333ff;"><item><xliff:g id="id">headset</xliff:g></item></span>
<item><xliff:g id="id">wifi</xliff:g></item>
</string-array>

3. 修改android\frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\phone\PhoneStatusBarPolicy.java

private BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(Intent.ACTION_ALARM_CHANGED)) {
updateAlarm(intent);
}
else if (action.equals(Intent.ACTION_SYNC_STATE_CHANGED)) {
updateSyncState(intent);
}
......

//add start

<span style="color:#3333ff;">            else if (action.equals(Intent.ACTION_HEADSET_PLUG)) {
updateHeadset(intent);
}//zhanbing add end
</span>	}

 

public PhoneStatusBarPolicy(Context context) {
mContext = context;
mService = (StatusBarManager)context.getSystemService(Context.STATUS_BAR_SERVICE);

// listen for broadcasts
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_ALARM_CHANGED);
filter.addAction(TtyIntent.TTY_ENABLED_CHANGE_ACTION);
......

<span style="color:#3333ff;">filter.addAction(Intent.ACTION_HEADSET_PLUG);//zhanbing add
</span>        mContext.registerReceiver(mIntentReceiver, filter, null, mHandler);

......

<span style="color:#3333ff;">//headset zhanbing.li add
        mService.setIcon("headset", R.drawable.stat_sys_headset, 0, null);
        mService.setIconVisibility("headset", false);
        //zhanbing modify here end</span>

<span style="color:#000066;">//modify here start</span>

<span style="color:#000066;">private final void updateHeadset(Intent intent) {
        Slog.d(TAG, "updateHeadset: state=" + intent.getIntExtra("state", 0));
        mService.setIconVisibility("headset", (intent.getIntExtra("state", 0) == 1)?true:false);</span>

<span style="color:#000066;">}</span>

<span style="color:#000066;">//modify here end</span>
