android中一些特殊字符（如：←↑→↓等箭头符号）的Unicode码值

 在项目中，有时候在一些控件（如Button、TextView)中要添加一些符号，如下图所示：

                        

这个时候可以使用图片的方式来显示，不过这些可以直接使用Unicode码就直接显示出来了。

4个箭头图标的代码如下：

 

[html] view plain copy
 
  1. <RelativeLayout  
  2.             android:layout_width="0dp"  
  3.             android:layout_height="match_parent"  
  4.             android:layout_weight="1"  
  5.             android:gravity="center_horizontal" >  
  6.   
  7.             <Button  
  8.                 android:id="@+id/scroll_left"  
  9.                 android:layout_width="40dip"  
  10.                 android:layout_height="40dip"  
  11.                 android:layout_alignParentLeft="true"  
  12.                 android:layout_centerVertical="true"  
  13.                 android:text="@string/left_arrow" />  
  14.   
  15.             <Button  
  16.                 android:id="@+id/scroll_up"  
  17.                 android:layout_width="40dip"  
  18.                 android:layout_height="40dip"  
  19.                 android:layout_alignParentTop="true"  
  20.                 android:layout_toRightOf="@id/scroll_left"  
  21.                 android:text="@string/up_arrow" />  
  22.   
  23.             <Button  
  24.                 android:id="@+id/scroll_down"  
  25.                 android:layout_width="40dip"  
  26.                 android:layout_height="40dip"  
  27.                 android:layout_below="@id/scroll_up"  
  28.                 android:layout_toRightOf="@id/scroll_left"  
  29.                 android:text="@string/down_arrow" />  
  30.   
  31.             <Button  
  32.                 android:id="@+id/scroll_right"  
  33.                 android:layout_width="40dip"  
  34.                 android:layout_height="40dip"  
  35.                 android:layout_centerVertical="true"  
  36.                 android:layout_toRightOf="@id/scroll_down"  
  37.                 android:text="@string/right_arrow" />  
  38.         </RelativeLayout>  



 

皇冠和音乐图标代码如下：

[html] view plain copy
 
  1. <LinearLayout  
  2.      android:layout_width="wrap_content"  
  3.      android:layout_height="wrap_content"  
  4.      android:orientation="vertical" >  
  5.   
  6.      <Button  
  7.          android:layout_width="wrap_content"  
  8.          android:layout_height="wrap_content"  
  9.          android:text="@string/music" />  
  10.   
  11.      <Button  
  12.          android:layout_width="wrap_content"  
  13.          android:layout_height="wrap_content"  
  14.          android:text="@string/crown" />  
  15.  </LinearLayout>  

 

 

上面的几个字符串值为：

 

[html] view plain copy
 
  1. <string name="music">\u265A</string>  
  2. <string name="crown">\u266B</string>  
  3.   
  4. <string name="left_arrow">\u2190</string>  
  5. <string name="up_arrow">\u2191</string>  
  6. <string name="down_arrow">\u2193</string>  
  7. <string name="right_arrow">\u2192</string>

从网上找到了部分关于特殊符号的Unicode码值，记录下来，以备后用，如下所示：  
用Android的string.xml中使用Unicode表示符号的话，就使用下面的JS相关的Unicode值即可
