Android implements text copy to clipboard function (ClipboardManager)

Android also has a clipboard (ClipboardManager), which can copy some useful text to the clipboard, so that the user can use it where it can be pasted. The following is how to use it

 

Note: when guiding the package

Before API 11: android.text.ClipboardManager
After API 11: android.content.ClipboardManager

 

copy code code show as below:

/** 
* Implement text copy function 
* add by wangqianzhou 
* @param content 
*/  
public static void copy(String content, Context context)  
{  
// Get  
ClipboardManager cmb = (ClipboardManager)context.getSystemService(Context.CLIPBOARD_SERVICE );  
cmb.setText(content.trim());  
}  
/** 
* Implement the paste function 
* add by wangqianzhou 
* @param context 
* @return 
*/  
public static String paste(Context context)  
{  
// Get the clipboard manager  
ClipboardManager cmb = (ClipboardManager)context.getSystemService(Context.CLIPBOARD_SERVICE);  
return cmb.getText().toString().trim();  
}  

First create a ClipboardManager object cmb and associate it with the system clipboard. After that, the content of String type can be copied to the clipboard through the setText(CharSequence text) function. In addition, the ClipboardManager class also provides the abstract CharSequence getText() function and the abstract boolean hasText() function, which can obtain the string content in the clipboard and query whether the clipboard currently has content. There are two versions of the ClipboardManager class. The clipboard manager that can only save strings, which has been supported since API Level 1, is used here. Since Android 3.0 (API Level 11), the new version of the ClipboardManager class supports more functions. . See the official documentation for details.

 

Versions before android2.1 use the following methods

copy code code show as below:

IClipboard clip = IClipboard.Stub.asInterface(ServiceManager.getService("clipboard")); 
clip.getClipboardText().toString();//Get the copied content 
clip.setClipboardText(text);//Set the content of Clipboard
