android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="clickMeMethod"

android:layout_height="wrap_content"
android:layout_below="@+id/button2"
android:layout_centerHorizontal="true"
android:layout_marginTop="39dp"
android:text="Click me too" />
</RelativeLayout>
Now made the following changes in the MainActivity.java file which is on the package coming under the Src folder.
package com.buttondemo;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends Activity {
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.bn);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "You click the CLICK ME TOO button", Toast.LENGTH_LONG).show();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void clickMeMethod(View v)
{
Toast.makeText(getBaseContext(), "You just click CLICK ME button", Toast.LENGTH_LONG).show();
}
}
