relativelayout

RelativeLayout 接着上一篇，本篇我将介绍RelativeLayout（相对布局）的一些知识点。 RelativeLayout 这是一个非常常用的布局，相比于上节所学到的LinearLayout布局，它更加的随意，可以通过相对定位的方式让控件出现在布局的任何位置。新建UILayoutTestTwo工程，修改activity_main.xml中的代码： <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <Button android:id="@+id/button_one" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:text="button 1"/> <Button android:id

3、绝对布局 AbsoluteLayout 绝对定位AbsoluteLayout，又可以叫做坐标布局，可以直接指定子元素的绝对位置，这种布局简单直接，直观性强，但是由于手机屏幕尺寸差别比较大，使用绝对定位的适应性会比较差。 下面我们举一个例子看看：例子里的机器人图片大小是250X250，可以看到我们使用android:layout_x和android:layout_y来指定子元素的纵横坐标。 <?xml version=”1.0″ encoding=”utf-8″?> <AbsoluteLayout android:id=”@+id/AbsoluteLayout01″ android:layout_width=”fill_parent” android:layout_height=”fill_parent” xmlns:android=” http://schemas.android.com/apk/res/android” android:background=”#fff”> <ImageView android:src=”@drawable/android” android:layout_y=”40dip” android:layout_width=”wrap_content” android:layout_x=”35dip” android:id=”@+id

I don't know why, but layout is shown well on device with Api 11+, isn't for older. This is xml: <LinearLayout android:id="@+id/workers_linearlayout" android:layout_width="50dp" android:layout_height="70dp" android:layout_weight="1" > <RelativeLayout android:id="@+id/workers_relative_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" > <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:src="@drawable/workers_small" /> <ImageView

Below is the xml layout of the first screenshot. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <TextView android:id="@+id/timer_textview" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:layout_marginTop="10dip" android:textSize="30sp" android:layout_alignParentTop="true" android
