Question

I am using Linear Layout(Horizontal) for my Android application. I am using two buttons for my screen which I have called as Chat and Draw. I want to display a second activity on clicking on Chat button in which I have an area for editText and a corresponding button called as Enter for entering the text.

In the DisplayMessageActivity class which I am using for Chat button, I have created the layout for editText and Enter button too. But however, on clicking on Chat I am not being able to see the area for editText and the button Enter.

Code in MainActivity.java :

public class MainActivity extends Activity {

public final static String EXTRA_MESSAGE = "com.example.appfirst.MESSAGE";

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

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}


public void chatMessage(View view) {
    Intent intent_chat = new Intent(this, DisplayMessageActivity.class);
    startActivity(intent_chat);
}

public void drawing(View view) {
    Intent intent_draw = new Intent(this, DisplayMessageActivity.class);
    startActivity(intent_draw);
}

}

code in DisplayMessageActivity.java :

public class DisplayMessageActivity extends Activity {

@SuppressLint("NewApi")

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);        

}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case android.R.id.home:
        NavUtils.navigateUpFromSameTask(this);
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}

What code should I write in the OnCreate function of DisplayMessageActivity class so that I am able to get the desired view ?

Can someone help me with the code. I am totally new to Android Development Framework. Thanks and Regards.

From your post i understand that u have 2 layouts 1 with 2 buttons "Chat" and "Draw".And when clicking chat u have to call another activity with Edittext and Enter button in it.If this is the case you simply call the Intent.

Intent intent=new Intent(this,yourclass.class);
startactivity(intent);

In Oncreate of your DisplayMessage do the following:

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

}
