MTK6577+Android4.0之增加重启功能

 

长按power按键，弹出下图：

图1

这里要实现增加Reboot的功能，下面记下要实现所做的修改。

1.     在长按power按键弹出的界面增加Reboot界面

 

首先关机的那个弹出菜单是在

frameworks/base/policy/src/com/android/internal/policy/impl/GlobalActions.java这个文件中的private AlertDialog createDialog()，如下：

   

 /**
     * Create the global actions dialog.
     * @return A new dialog.
     */
    private AlertDialog createDialog() {
        mSilentModeAction = newSilentModeAction(mAudioManager, mHandler);
 
        mAirplaneModeOn = new ToggleAction(
               R.drawable.ic_lock_airplane_mode,
               R.drawable.ic_lock_airplane_mode_off,
                R.string.global_actions_toggle_airplane_mode,
               R.string.global_actions_airplane_mode_on_status,
               R.string.global_actions_airplane_mode_off_status) {
 
            void onToggle(boolean on) {
                if (Boolean.parseBoolean(
                        SystemProperties.get(TelephonyProperties.PROPERTY_INECM_MODE))){
                    mIsWaitingForEcmExit =true;
                    // Launch ECM exit dialog
                    Intent ecmDialogIntent =
                            new Intent(TelephonyIntents.ACTION_SHOW_NOTICE_ECM_BLOCK_OTHERS,null);
                   ecmDialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                   mContext.startActivity(ecmDialogIntent);
                } else {
                    changeAirplaneModeSystemSetting(on);
                }
            }
 
            @Override
            protected voidchangeStateFromPress(boolean buttonOn) {
                // In ECM mode airplane statecannot be changed
                if (!(Boolean.parseBoolean(
                       SystemProperties.get(TelephonyProperties.PROPERTY_INECM_MODE)))) {
                    mState = buttonOn ?State.TurningOn : State.TurningOff;
                    mAirplaneState = mState;
                }
            }
 
            public boolean showDuringKeyguard(){
                return true;
            }
 
            public booleanshowBeforeProvisioning() {
                return false;
            }
           
            //M{
           public boolean isEnabled() {
               if(KeyguardUpdateMonitor.dual_sim_setting == 0){
                    Log.e(TAG, "if userunselect the dual sim mode setting on phone starting, the airplane mode can notbe set.");
                    return false; //if user hasnot yet selected any item in the dual_sim_mode_setting dialog on phonestarting, the airplane mode should be disabled.
                }
                else {
                       returnsuper.isEnabled();
                }
            }
            //}M
        };
 
        mItems = new ArrayList<Action>();
 
        // first: power off
        mItems.add(
            new SinglePressAction(
                   com.android.internal.R.drawable.ic_lock_power_off,
                   R.string.global_action_power_off) {
 
                public void onPress() {
                    // shutdown by making sureradio and power are handled accordingly.
                   ShutdownThread.shutdown(mContext, true);
                }
 
                public booleanshowDuringKeyguard() {
                    return true;
                }
 
                public booleanshowBeforeProvisioning() {
                    return true;
                }
            });
             
        
        // next: airplane mode
        mItems.add(mAirplaneModeOn);
 
        // last: silent mode
        if (SHOW_SILENT_TOGGLE) {
            mItems.add(mSilentModeAction);
        }
 
        mAdapter = new MyAdapter();
 
        final AlertDialog.Builder ab = newAlertDialog.Builder(mContext);
 
        ab.setAdapter(mAdapter, this)
                .setInverseBackgroundForced(true);
 
        final AlertDialog dialog = ab.create();
       dialog.getListView().setItemsCanFocus(true);
       dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_DIALOG);
 
        dialog.setOnDismissListener(this);
 
        return dialog;
}

上面的代码在// first: power off和// next: airplane mode之间增加了reboot部分，代码如下：

// second:reboot,kandi add at 2015.01.21
         mItems.add(
            new SinglePressAction(
                   com.android.internal.R.drawable.ic_lock_reboot,
                   R.string.global_action_reboot) {
 
                public void onPress() {
                    // shutdown by making sureradio and power are handled accordingly.
                    ShutdownThread.reboot(mContext,null, true);
                }
 
                public booleanshowDuringKeyguard() {
                    return true;
                }
 
                public booleanshowBeforeProvisioning() {
                    return true;
                }
            });

此代码主要阐述下面几点：

(1)  增加字符串global_action_reboot和图片资源ic_lock_reboot，这些的定义在后面描述。

(2)  ShutdownThread.reboot(mContext,null, true)此函数是调用

/**
     * Request a clean shutdown, waiting forsubsystems to clean up their
     * state etc.  Must be called from a Looper thread in whichits UI
     * is shown.
     *
     * @param context Context used to displaythe shutdown progress dialog.
     * @param reason code to pass to the kernel(e.g. "recovery"), or null.
     * @param confirm true if user confirmationis needed before shutting down.
     */
    public static void reboot(final Contextcontext, String reason, boolean confirm) {
        mReboot = true;
        mRebootReason = reason;
        shutdown(context, confirm);
}

reason 如果值为是null，正常重启；如果是recovery，系统重启进入recovery mode

confirm true显示关机提示框，需要用户；false不显示提示框，直接关机。

2.     增加点击Reboot后的重启

为了在按下重启选项之后，能出现”重启“之类的提示，还需要修改frameworksasecorejavacomandroidinternalapp ShutdownThread.java中的shutdown函数和beginShutdownSequence函数：

 

(1)  shutdown函数

修改之前
final intresourceId = longPressBehavior == 2
    ? com.android.internal.R.string.shutdown_confirm_question
: com.android.internal.R.string.shutdown_confirm;
修改之后
final intresourceId = longPressBehavior == 2
    ? com.android.internal.R.string.shutdown_confirm_question
    : (mReboot ?com.android.internal.R.string.reboot_confirm :
    com.android.internal.R.string.shutdown_confirm);

(2)  beginShutdownSequence函数

修改之前：
pd.setTitle(context.getText(com.android.internal.R.string.power_off));        
pd.setMessage(context.getText(com.android.internal.R.string.shutdown_progress));
 
修改之后：
if(mReboot)
              {
                     pd.setTitle(context.getText(com.android.internal.R.string.global_action_reboot));
                           pd.setMessage(context.getText(com.android.internal.R.string.reboot_progress));
              }
              else
              {
                     pd.setTitle(context.getText(com.android.internal.R.string.power_off));
                          pd.setMessage(context.getText(com.android.internal.R.string.shutdown_progress));
              }

3.     增加字符串和图片资源

 

(1)  增加字符串

在frameworks/base/core/res/res/values/strings.xml中添加一下字符串：

<stringname="reboot_progress">Reboot...u2026</string>
<stringname="reboot_confirm" product="default">Your phone willReboot.</string>
<stringname="reboot_confirm" product="default">Your phone willReboot.</string>
<stringname="global_action_reboot">Reboot</string>
<stringname="reboot">Reboot2</string>

在frameworksasecore es esvaluespublic.xml增加以下字符串

<publictype="drawable" name="ic_menu_sort_by_size"id="0x0108009d" />//已有
<publictype="drawable" name="ic_lock_reboot"id="0x0108009e" />//增加

(2)  增加重启的图片资源

把ic_lock_reboot.png拷贝到frameworksasecore es esdrawable-hdpi目录下

 

4.     编译及升级

./mk r dr，然后单独升级system.img
