Android how to get string from clipboard onPrimaryClipChanged?

Question

I'm trying to get text copied into the clipboard using the following listener:

import android.content.ClipboardManager.OnPrimaryClipChangedListener;
import com.orhanobut.logger.Logger;

public class ClipboardListener implements OnPrimaryClipChangedListener
{

    public void onPrimaryClipChanged()
    {
        // do something useful here with the clipboard
        // use getText() method
        Logger.d("Clipped");
    }
}

The listener is initialized as follows:

ClipboardManager clipBoard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
clipBoard.addPrimaryClipChangedListener( new ClipboardListener());

After the text is copied into the clipboard onPrimaryClipChanged is fired, but I don't know how to get the copied text in this method using ClipboardManager.getPrimaryClip() because the method is not available from the context and is not passed in the param of onPrimaryClipChanged.

I would suggest adding the listener as follows instead of creating a new class. I have included how to get text from the ClipData.

You mention being unable to access your context in the listener, I've added a comment within the code below showing how to do so.

ClipboardManager clipBoard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
clipBoard.addPrimaryClipChangedListener(new OnPrimaryClipChangedListener() {

    @Override
    public void onPrimaryClipChanged() {
        ClipData clipData = clipBoard.getPrimaryClip();
        ClipData.Item item = clipData.getItemAt(0);
        String text = item.getText().toString();

        // Access your context here using YourActivityName.this
    }
});
