青春壹個敷衍的年華 提交于 2020-03-01 05:06:25
问题 I am trying to find an example of how to update a view on multiple tables using an instead of trigger. That is I want update more than one table that this view selects from.

UICollectionView的基本使用

这个控件,看起来与UITableView有点像,而且基本的用法也很相像哦!!! 我们来看看API: [objc] view plain copy print ? #pragma mark - UICollectionViewDataSource // 指定Section个数 - (NSInteger)numberOfSectionsInCollectionView:( UICollectionView *)collectionView { return 3; } // 指定section中的collectionViewCell的个数 - (NSInteger)collectionView:( UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section { return 1 0; } // 配置section中的collectionViewCell的显示 - ( UICollectionViewCell *)collectionView:( UICollectionView *)collectionView cellForItemAtIndexPath:( NSIndexPath *)indexPath { CollectionViewCell *cell = [collectionView

视图添删、切换、显示以及坐标转换

1 视图添删 1>,移除某个视图 只是暂时从窗口移除,不是切地删除 [sender removeFromSuperview]; 2>,添加视图或视图控制器 addSubView:多用于添加控件,是添加在self.view的上面 addChildViewController:多用于添加控制器,是添加self的上面 //注意:子类不声明self.superB addSubView:self.A,而是self.view addSubView:self.A // 那么父类中必须声明[self.A superView] 例子: - (UIImageView *)imageTom { if (_imageTom == nil) { UIImageView *imageTom = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; _imageTom = imageTom; [self.imageTom setImage:[UIImage imageNamed:@"eat_00.jpg"]]; [self.view addSubview:self.imageTom]; //一定要实现!!!!!!!!!! [self.eatCat superview]; } return _imageTom; } - (UIButton

自定义View的一些总结

若如初见. 提交于 2020-02-29 05:38:37
一、自定义View 1、构造方法的选中,获取一些需要用到的值 2、重写onMeasure方法,计算子View的宽高,以及自己的宽高 3、重写onLayout方法,决定子View的布局位置 4、需要用的手势是可重写onTouchEvent方法 二、构造方法 1、一个参数的构造方法 context new CustomSidingView(context) 2、两个参数的构造方法 Context context, AttributeSet attrs(布局文件中申明的属性,在没有自定义属性的情况下) CustomSidingView(Context context, AttributeSet attrs) 3、三个参数的构造方法 Context context, AttributeSet attrs, int defStyle(有自定义属性时并用自定义属性时调用) CustomSidingView(Context context, AttributeSet attrs, int defStyle) 在自定义属性的时候一般三个构造方法都会用 在一个参数的构造方法调用 this(context, null); 在两个参数的构造方法中调用 this(context, attrs, 0); 在三个参数的构造方法中调用 super(context, attrs, defStyle); 三

Android: How to make the views the same height dynamically

爱⌒轻易说出口 提交于 2020-02-25 23:28:12
问题 I'm making one table in Android application. Now I cannot make the views the same height. There are 2 TextView s, tmp_name and tmp_content in each row. the height of tmp_content depends on the length of course_description(i) . tmp_content sets its height automatically. I'd like to get the height of tmp_content and reset the height of tmp_name same with tmp_content . If you have any tips, please let me know. for (int i = 0; i < course_name.size(); i++) { TableRow.LayoutParams lp = new TableRow
