[1]透过NSNotificationCenter更改被选中的背景色
    来源: 互联网  发布时间: 2014-02-18
通过NSNotificationCenter更改被选中的背景色

1，通过NSNotificationCenter注册监听事件

 

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(menuWillShow:)
                                                 name:UIMenuControllerWillShowMenuNotification
                                               object:nil];
 

 

2，当UIMenu 显示的时候调用以下方法

 

- (void) menuWillShow:(NSNotification *)notification
{
    self.selectionStyle = UITableViewCellSelectionStyleBlue;
    if ((self.delegate != nil) && [self.delegate respondsToSelector:@selector(emailableCell:selectCellAtIndexPath:)]) {
        [self.delegate emailableCell:self selectCellAtIndexPath:self.indexPath];
    }

    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:UIMenuControllerWillShowMenuNotification
                                                  object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(menuWillHide:)
                                                 name:UIMenuControllerWillHideMenuNotification
                                               object:nil];
}

3，当UIMenu 消失的时候调用以下方法

 

- (void) menuWillHide:(NSNotification *)notification
{
    if ((self.delegate != nil) && [self.delegate respondsToSelector:@selector(emailableCell:deselectCellAtIndexPath:)]) {
        [self.delegate emailableCell:self deselectCellAtIndexPath:self.indexPath];
    }

    self.selectionStyle = UITableViewCellSelectionStyleNone;
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:UIMenuControllerWillHideMenuNotification
                                                  object:nil];
}
 

    
[2] 【转】Service怎么关闭启动自己的Activity
    来源: 互联网  发布时间: 2014-02-18
【转】Service如何关闭启动自己的Activity

今天在编写Android程序的时候，遇到这个问题。通过百度和google的搜索结果，总结出以下方法：
方法一：
public class mService extends Service {
//保存在service中的Activity对象
private static mActivity m;
//启动服务
static void startservice(Context c){
m=(mActivity)c;
Intent iService=new Intent(c,mService.class);
iService.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
c.startActivity(iService);
}
//关闭服务
static void stopservice(Context c){
Intent iService=new Intent(c,mService.class);
iService.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
c.stopService(iService);
}
……
//在mService中关闭mActivity
m.finish();
}

public class mActivity extends Activity {

// private MediaPlayer mMPlayer;
/*
* (non-Javadoc)
* @see android.app.Activity#onCreate(android.os.Bundle)
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
……
//启动mService
mService.startservice(mActivity.this);
……
//停止mService
mService.stopservice(mActivity.this);

}
}

方法二：
主要包括3部分
1. 定义application类，这个类可以保存获取activity实例，记得manifest中加入android:name=".MyApp"
public class MyApp extends Application{
private MyServiceActivity myActivity;

public void setInstance(MyServiceActivity instance){
myActivity = instance;
}

public MyServiceActivity getInstance(){
return myActivity;
}
}
2. 在activity中保存实例
public class MyServiceActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
((MyApp)getApplication()).setInstance(this);
……
}
}
3. 在service中取回实例
public class MyService extends Service {
MyServiceActivity myActivity;
@Override
public void onCreate() {
super.onCreate();
setForeground(true);
android.os.Debug.waitForDebugger();
myActivity = ((MyApp)getApplication()).getInstance();
……
}
}
