Android provides the clipboard framework for copying and pasting different types of data. The data could be text, images, binary stream data or other complex data types.

Android provides the library of ClipboardManager and ClipData and ClipData.item to use the copying and pasting framework.In order to use clipboard framework, you need to put data into clip object, and then put that object into system wide clipboard.

In order to use clipboard , you need to instantiate an object of ClipboardManager by calling the getSystemService() method. Its syntax is given below −

ClipboardManager myClipboard;
myClipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);

Copying data

The next thing you need to do is to instantiate the ClipData object by calling the respective type of data method of the ClipData class. In case of text data , the newPlainText method will be called. After that you have to set that data as the clip of the Clipboard Manager object.Its syntax is given below −

ClipData myClip;
String text = "hello world";
myClip = ClipData.newPlainText("text", text);
myClipboard.setPrimaryClip(myClip);

The ClipData object can take these three form and following functions are used to create those forms.

Pasting data

In order to paste the data, we will first get the clip by calling the getPrimaryClip() method. And from that click we will get the item in ClipData.Item object. And from the object we will get the data. Its syntax is given below −

ClipData abc = myClipboard.getPrimaryClip();
ClipData.Item item = abc.getItemAt(0);
String text = item.getText().toString();

Apart from the these methods , there are other methods provided by the ClipboardManager class for managing clipboard framework. These methods are listed below −

Example

Here is an example demonstrating the use of ClipboardManager class. It creates a basic copy paste application that allows you to copy the text and then paste it via clipboard.

To experiment with this example , you can run this on an actual device or in an emulator.

Following is the content of the modified main activity file src/MainActivity.java.

package com.example.sairamkrishna.myapplication;

import android.content.ClipData;
import android.content.ClipboardManager;
import android.os.Bundle;

import android.support.v7.app.ActionBarActivity;
import android.view.View;

import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;


public class MainActivity extends ActionBarActivity {
   EditText ed1, ed2;
   Button b1, b2;

   private ClipboardManager myClipboard;
   private ClipData myClip;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);

      ed1 = (EditText) findViewById(R.id.editText);
      ed2 = (EditText) findViewById(R.id.editText2);

      b1 = (Button) findViewById(R.id.button);
      b2 = (Button) findViewById(R.id.button2);

      myClipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);

      b1.setOnClickListener(new View.OnClickListener() {
         
         @Override
         public void onClick(View v) {
            String text;
            text = ed1.getText().toString();

            myClip = ClipData.newPlainText("text", text);
            myClipboard.setPrimaryClip(myClip);

            Toast.makeText(getApplicationContext(), "Text Copied", 
               Toast.LENGTH_SHORT).show();
         }
      });

      b2.setOnClickListener(new View.OnClickListener() {
         
         @Override
         public void onClick(View v) {
            ClipData abc = myClipboard.getPrimaryClip();
            ClipData.Item item = abc.getItemAt(0);

            String text = item.getText().toString();
            ed2.setText(text);

            Toast.makeText(getApplicationContext(), "Text Pasted", 
               Toast.LENGTH_SHORT).show();
         }
      });
   }

Let”s try to run our an application we just modified. I assume you had created your AVD while doing environment setup. To run the app from Android studio, open one of your project”s activity files and click Run icon from the tool bar. Android studio installer will display following images −

Now just enter any text in the Text to copy field and then select the copy text button. The following notification will be displayed which is shown below −

Now just press the paste button, and you will see the text which is copied is now pasted in the field of Copied Text. It is shown below −
