Puede copiar y pegar texto utilizando código siguiente …

 //for copy ClipboardManager clipboard = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE); ClipData clip = ClipData.newPlainText("your_text_to_be_copied"); clipboard.setPrimaryClip(clip); // And paste it ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); String pasteData = ""; // If it does contain data, decide if you can handle the data. if (!(clipboard.hasPrimaryClip())) { } else if (!(clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_PLAIN))) { // since the clipboard has data but it is not plain text } else { //since the clipboard contains plain text. ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0); // Gets the clipboard as text. pasteData = item.getText().toString(); } }

Un breve resumen de arriba después de nido de abeja> = API 13:

 public String readFromClipboard() { ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); if (clipboard.hasPrimaryClip()) { android.content.ClipDescription description = clipboard.getPrimaryClipDescription(); android.content.ClipData data = clipboard.getPrimaryClip(); if (data != null && description != null && description.hasMimeType(ClipDescription.MIMETYPE_TEXT_PLAIN)) return String.valueOf(data.getItemAt(0).getText()); } return null; }

 ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); String copyedText = clipboard.getText(); 

Puede establecer texto cada EditText de su elección para el contenido de ClipboardManager.

 ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE) EditText editText = (EditText)findViewById(R.id.YOUR_TEXT); editText.setText(clipboard.getText()); 

Creo que algunas de las otras respuestas pueden ser correctas, pero son difíciles de seguir. Si sólo desea "copiar y pegar" algún código en su aplicación, puede utilizar lo siguiente.

Dupdo

 String textToCopy = etCodeWindow.getText().toString(); int sdk = android.os.Build.VERSION.SDK_INT; if(sdk < android.os.Build.VERSION_CODES.HONEYCOMB) { android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); clipboard.setText(textToCopy); } else { android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); android.content.ClipData clip = android.content.ClipData.newPlainText("myLabel", textToCopy); clipboard.setPrimaryClip(clip); } 

Pegar

 CharSequence textToPaste = null; // get the text from the clipboard manager int sdk = android.os.Build.VERSION.SDK_INT; if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) { android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); try { textToPaste = clipboard.getText(); } catch (Exception e) { e.printStackTrace(); } } else { android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); if (clipboard.getPrimaryClip() != null) { android.content.ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0); textToPaste = item.getText(); } } // insert the text at the cursor position, or if there is a selection it // replaces the selection with the text to paste if (textToPaste != null) { int start = Math.max(myEditText.getSelectionStart(), 0); int end = Math.max(myEditText.getSelectionEnd(), 0); myEditText.getText().replace(Math.min(start, end), Math.max(start, end), textToPaste, 0, textToPaste.length()); } 

Notas

• Obtendrá advertencias de compilador sobre la depreciación y nuevas API si utiliza el código anterior directamente. Vea mi respuesta un poco más larga sobre cómo silenciar esas advertencias.
• Si no necesita soportar pre API 11, entonces puede simplificar bastante el código anterior.
• Gracias a esta y esta respuesta por ayuda.
