修改状态栏(StatusBar)图标(icon)(定制自己的状态栏)

系统定制需要修改一下状态栏，如果想要刷机的话，网上资料挺多的，但是修改源代码的资料不多，在2.2中，源代码在frameworks/base/services/java/com/android/server/status/StatusBarPolicy.java和frameworks/base/services/java/com/android/server/status/StatusBarService.java中，在2.3中，源代码在：frameworks/base/package里面的SystemUI里面。

            在StatusBarPolicy中，添加图标的代码如下（404行）：

  

public StatusBarPolicy(Context context) {
       mContext = context;
       mService = (StatusBarManager)context.getSystemService(Context.STATUS_BAR_SERVICE);
       mSignalStrength = new SignalStrength();
       mBatteryStats = BatteryStatsService.getService();

       // storage
       mStorageManager = (StorageManager) context.getSystemService(Context.STORAGE_SERVICE);
       mStorageManager.registerListener(
               new com.android.systemui.usb.StorageNotification(context));

       // battery
       mService.setIcon("battery", com.android.internal.R.drawable.stat_sys_battery_unknown, 0);

       // phone_signal
       mPhone = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
       mPhoneSignalIconId = R.drawable.stat_sys_signal_null;
       mService.setIcon("phone_signal", mPhoneSignalIconId, 0);
       mService.setIconVisibility("phone_signal",false);

       // register for phone state notifications.
       ((TelephonyManager)mContext.getSystemService(Context.TELEPHONY_SERVICE))
               .listen(mPhoneStateListener,
                         PhoneStateListener.LISTEN_SERVICE_STATE
                       | PhoneStateListener.LISTEN_SIGNAL_STRENGTHS
                       | PhoneStateListener.LISTEN_CALL_STATE
                       | PhoneStateListener.LISTEN_DATA_CONNECTION_STATE
                       | PhoneStateListener.LISTEN_DATA_ACTIVITY);

       // data_connection
       mService.setIcon("data_connection", R.drawable.stat_sys_data_connected_g, 0);
       mService.setIconVisibility("data_connection", false);

       // wifi
       mService.setIcon("wifi", sWifiSignalImages[0][0], 0);
       mService.setIconVisibility("wifi", false);
       // wifi will get updated by the sticky intents

       // TTY status
       mService.setIcon("tty",  R.drawable.stat_sys_tty_mode, 0);
       mService.setIconVisibility("tty", false);

       // Cdma Roaming Indicator, ERI
       mService.setIcon("cdma_eri", R.drawable.stat_sys_roaming_cdma_0, 0);
       mService.setIconVisibility("cdma_eri", false);

       // bluetooth status
       mService.setIcon("bluetooth", R.drawable.stat_sys_data_bluetooth, 0);
       BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
       if (adapter != null) {
           mBluetoothEnabled = adapter.isEnabled();
       } else {
           mBluetoothEnabled = false;
       }
       mBluetoothA2dpConnected = false;
       mBluetoothHeadsetState = BluetoothHeadset.STATE_DISCONNECTED;
       mBluetoothPbapState = BluetoothPbap.STATE_DISCONNECTED;
       mService.setIconVisibility("bluetooth", mBluetoothEnabled);

       // Gps status
       mService.setIcon("gps", R.drawable.stat_sys_gps_acquiring_anim, 0);
       mService.setIconVisibility("gps", false);

       // Alarm clock
       mService.setIcon("alarm_clock", R.drawable.stat_notify_alarm, 0);
       mService.setIconVisibility("alarm_clock", false);

       // Sync state
       mService.setIcon("sync_active", com.android.internal.R.drawable.stat_notify_sync_anim0, 0);
       mService.setIcon("sync_failing", com.android.internal.R.drawable.stat_notify_sync_error, 0);
       mService.setIconVisibility("sync_active", false);
       mService.setIconVisibility("sync_failing", false);

       // volume
       mService.setIcon("volume", R.drawable.stat_sys_ringer_silent, 0);
       mService.setIconVisibility("volume", false);
       updateVolume();

       IntentFilter filter = new IntentFilter();

       // Register for Intent broadcasts for...
       filter.addAction(Intent.ACTION_BATTERY_CHANGED);
       filter.addAction(Intent.ACTION_BATTERY_LOW);
       filter.addAction(Intent.ACTION_BATTERY_OKAY);
       filter.addAction(Intent.ACTION_POWER_CONNECTED);
       filter.addAction(Intent.ACTION_ALARM_CHANGED);
       filter.addAction(Intent.ACTION_SYNC_STATE_CHANGED);
       filter.addAction(AudioManager.RINGER_MODE_CHANGED_ACTION);
       filter.addAction(AudioManager.VIBRATE_SETTING_CHANGED_ACTION);
       filter.addAction(BluetoothAdapter.ACTION_STATE_CHANGED);
       filter.addAction(BluetoothHeadset.ACTION_STATE_CHANGED);
       filter.addAction(BluetoothA2dp.ACTION_SINK_STATE_CHANGED);
       filter.addAction(BluetoothPbap.PBAP_STATE_CHANGED_ACTION);
       filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
       filter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
       filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
       filter.addAction(WifiManager.RSSI_CHANGED_ACTION);
       filter.addAction(LocationManager.GPS_ENABLED_CHANGE_ACTION);
       filter.addAction(LocationManager.GPS_FIX_CHANGE_ACTION);
       filter.addAction(TelephonyIntents.ACTION_SIM_STATE_CHANGED);
       filter.addAction(TtyIntent.TTY_ENABLED_CHANGE_ACTION);
       filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
       filter.addAction(ConnectivityManager.INET_CONDITION_ACTION);
       mContext.registerReceiver(mIntentReceiver, filter, null, mHandler);

       // load config to determine if to distinguish Hspa data icon
       try {
           mHspaDataDistinguishable = mContext.getResources().getBoolean(
                   R.bool.config_hspa_data_distinguishable);
       } catch (Exception e) {
           mHspaDataDistinguishable = false;
       }
   }

下面简单说一下用法，获取StatusBarManager：

private final StatusBarManager mService;

mService = (StatusBarManager)context.getSystemService(Context.STATUS_BAR_SERVICE);



<span style="font-size:14px;">下面是获得图标：获取以后处理</span>
// phone_signal
        mPhone = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        mPhoneSignalIconId = R.drawable.stat_sys_signal_null;
        mService.setIcon("phone_signal", mPhoneSignalIconId, 0);
        mService.setIconVisibility("phone_signal",false);

在这里，我把这个信号图标给隐藏了，所以当你编译编译源码，生成自己SDK，然后新建一个模拟器，就会发现信号图标已经没有了，如果你想改变布局，或者更改图标，在res里面找一下相应的文件，今天就写到这，其余信息，继续补充。
