Question

I am trying to develop a chat room for an Android App. I have a created some area for EditText and a corresponding button to Enter the text that is typed by a user.

On clicking on Enter I want to display the typed text on the same screen i.e. whatever text is being typed, it is subsequently being displayed on the same screen. I am using Linear Layout(Horizontal) for my app.

How can I implement this ?? Can someone help me with the code. I am totally new to Android Development Framework. Thanks and Regards.

Its very simple. You create the xml file with one textView and one edittext and one button. Then you handle the event of button click in mainActivity and call onResume from it. Override the onResume so that you can update the textview.

@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
    TextView text = (TextView) findViewById(R.id.txtView1);
    EditText editBox = (EditText)findViewById(R.id.txtBox1);
    String str = text.getText().toString();
    text.setText(str+" "+editBox.getText().toString());
    editBox.setText("");
    editBox.setHint("Type in here");

}
