In Android, you will get the clipboard functionality used to copy and paste various kinds of data. You can implement the Clipboard functionality on Android with the help of a library ClipboardManager and ClipData.item. The example below will demonstrate the use of ClipboardManager class for your android application. The steps you need to follow to implement the Clipboard application include:
1.You will need to create an application under a package – com.firstapp.ashulakhwan.greatlearning
2.Next, you need to modify the file named MainActivity.java with the following code:
package com.firstapp.ashulakhwan.greatlearning;
package com.firstapp.ashulakhwan.greatlearning;
import android.content.ClipData;
import android.content.ClipboardManager;
import android.os.Bundle;
import android.support.v8.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
EditText edit1, edit2;
Button btn1, btn2;
private ClipboardManager firstClipboard;
private ClipData firstClip;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edit1 = (EditText) findViewById(R.id.editText);
edit2 = (EditText) findViewById(R.id.editText2);
btn1 = (Button) findViewById(R.id.button);
btn2 = (Button) findViewById(R.id.button2);
firstClipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
btn1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String text;
text = edit1.getText().toString();
firstClip = ClipData.newPlainText("text", text);
firstClipboard.setPrimaryClip(firstClip);
Toast.makeText(getApplicationContext(), "The text is copied",
Toast.LENGTH_SHORT).show();
}
});
btn2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ClipData txt = firstClipboard.getPrimaryClip();
ClipData.Item item = txt.getItemAt(0);
String text = item.getText().toString();
edit2.setText(text);
Toast.makeText(getApplicationContext(), "The copied text is pasted.",
Toast.LENGTH_SHORT).show();
}
});
}
}
3.After that, you are required to modify the XML layout file which is named activity_main.xml and the content is shown below:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Great Learning"
android:id="@+id/textView"
android:layout_below="@+id/textview"
android:layout_centerHorizontal="true"
android:textColor="#d5d630"
android:textSize="40dp" />
<TextView android:text="ClipboardExample" android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textview"
android:textSize="40dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView"
android:layout_below="@+id/textView"
android:layout_centerHorizontal="true" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/editText"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:hint="Copy the text"
android:layout_below="@+id/imageView"
android:layout_alignLeft="@+id/imageView"
android:layout_alignStart="@+id/imageView" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/editText2"
android:layout_alignLeft="@+id/editText"
android:layout_alignStart="@+id/editText"
android:hint="paste the copied text"
android:layout_below="@+id/editText"
android:layout_alignRight="@+id/editText"
android:layout_alignEnd="@+id/editText" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Copy"
android:id="@+id/button"
android:layout_below="@+id/editText2"
android:layout_alignLeft="@+id/editText2"
android:layout_alignStart="@+id/editText2" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Paste"
android:id="@+id/button2"
android:layout_below="@+id/editText2"
android:layout_alignRight="@+id/editText2"
android:layout_alignEnd="@+id/editText2" />
</RelativeLayout>
4. In the next step, you will need to modify the AndroidManifest.xml with the code shown below:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.firstapp.ashulakhwan.greatlearning" >
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.firstapp.ashulakhwan.greatlearning.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
At last, you can run the application and check the results of your application.
