Android 的剪貼板(Clipboard)

於程序碼使用剪貼板(Clipboard), 可通過ClipboardManager類.



ClipboardManager是剪貼板服務的接口, 在剪貼板上放置和檢索文字.

你不直接實例化這個類，而是通過getSystemService(String)取得ClipboardManager. 再利用setText(CharSequence text)和getText()方法放置和檢索文字.

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
<TextView 
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="@string/hello"
   />
<EditText
   android:id="@+id/edittext"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   />
<Button
   android:id="@+id/copyto"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="Copy To ClipBoard"
   />
<Button
   android:id="@+id/pastefrom"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="Paste From ClipBoard"
   />
</LinearLayout>
