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）：

[java] view plain copy

publicStatusBarPolicy(Contextcontext){
mContext=context;
mService=(StatusBarManager)context.getSystemService(Context.STATUS_BAR_SERVICE);
mSignalStrength=newSignalStrength();
mBatteryStats=BatteryStatsService.getService();
//storage
mStorageManager=(StorageManager)context.getSystemService(Context.STORAGE_SERVICE);
mStorageManager.registerListener(
newcom.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);
//registerforphonestatenotifications.
((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);
//wifiwillgetupdatedbythestickyintents
//TTYstatus
mService.setIcon("tty",R.drawable.stat_sys_tty_mode,0);
mService.setIconVisibility("tty",false);
//CdmaRoamingIndicator,ERI
mService.setIcon("cdma_eri",R.drawable.stat_sys_roaming_cdma_0,0);
mService.setIconVisibility("cdma_eri",false);
//bluetoothstatus
mService.setIcon("bluetooth",R.drawable.stat_sys_data_bluetooth,0);
BluetoothAdapteradapter=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);
//Gpsstatus
mService.setIcon("gps",R.drawable.stat_sys_gps_acquiring_anim,0);
mService.setIconVisibility("gps",false);
//Alarmclock
mService.setIcon("alarm_clock",R.drawable.stat_notify_alarm,0);
mService.setIconVisibility("alarm_clock",false);
//Syncstate
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();
IntentFilterfilter=newIntentFilter();
//RegisterforIntentbroadcastsfor...
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);
//loadconfigtodetermineiftodistinguishHspadataicon
try{
mHspaDataDistinguishable=mContext.getResources().getBoolean(
R.bool.config_hspa_data_distinguishable);
}catch(Exceptione){
mHspaDataDistinguishable=false;
}
}

下面简单说一下用法，获取StatusBarManager：

private final StatusBarManager mService;

[java] view plain copy

mService=(StatusBarManager)context.getSystemService(Context.STATUS_BAR_SERVICE);
<spanstyle="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。
