Question

Please when I try to run this app it stops.

The problem is with OnEditorActionListener, if i delete the app loads and runs ok.

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.TextView.OnEditorActionListener;
import android.widget.Toast;

public class IMEDemo2 extends Activity  
{       EditText et;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            et.setOnEditorActionListener(new OnEditorActionListener() { 
                public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { 
                    }
                    Toast.makeText(getApplicationContext(), "OK", Toast.LENGTH_LONG).show();    
                    return true; 
                } 
            });             
    }

}

You aren’t initializing your et field so when you try to set the listener, you will get a NullPointerException.

To initialize et, put…

et = (EditText) findViewById(R.id.myEditText);

…before the line et.setOnEditorActionListener(...).

Change R.id.myEditText in my example to whatever the resource id is in your main.xml file.
