Android Scrollview in RelativeLayout with ButtonBar

我怕爱的太早我们不能终老 提交于 2019-11-30 19:11:00
I'm trying to implement a login view where several EditTexts and a logo are displayed on the screen with a ButtonBar at the bottom, something like this: alt text http://russellhaering.com/media/addAccount.png The problem is that on very small screens, especially when they are rotated sideways, the entire main view doesn't fit onto the screen. I currently have <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#234C59" > <LinearLayout android

Dynamically adding content to RelativeLayout

问题 Since I'm still just learning Android (and it appears Amazon says it'll be 2 months till I get the Hello, Android book) I'm still playing around with doing simple things. I have no problem getting an icon to display with the click of a button on my RelativeLayout using ImageView. The code for creating it is as follows: private int mIconIdCounter = 1; private ImageView addIcon(){ ImageView item = new ImageView(this); item.setImageResource( R.drawable.tiles ); item.setAdjustViewBounds(true);

Android 第七课——UI布局

Android布局分为:线性布局、相对布局、表格布局、帧布局、网格布局五种 布局中的距离单位:dp、px、sp。 布局继承关系图: 1)熟悉几个常用属性 <Button android:id="@+id/loginName" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/login"/> 1) android:id="@+id/loginName" 为组件自定义一个ID,便于在程序中通过映射R文件查找:R.id.loginName ; 2)android:layout_width 与 android:layout_height 设置组件的宽与高,只有三个值,分别是: match_parent:充满父容器, 新版本中使用,推荐使用这个属性值 fill_parent:充满父容器, 老版本中使用 wrap_content:包裹文字,根据文字的大小来设定组件的大小 3)android:text="@string/login" 从常量中获取对应的引用值 2) LinearLayout 线性布局 线性布局即 LinearLayout 布局,是Android屏幕中常用的布局方式,是一个ViewGroup以 线性方向显示 它的子视图(View)元素

How to display a button in random screen position

一世执手 提交于 2019-11-30 08:43:32
问题 How do I display a button in a random screen position in android? For example I have a button that is named GO. When I click GO, it will bring me to the second screen. That second screen will display another button (not the START button) in random screen position. How can I do that? 回答1: For the second screen use absolute layout , but the button on X=0, Y=0 Once your second screen gets activated. onCreate Method Button button = (Button)findViewById(R.id.my_button); AbsoluteLayout.LayoutParams
