How to make a simple menu program of Android?

Question

tell the code of simple program of android application.

Answer 1

I've created a simple Android app below that creates a view with a text box and when the activity is initialised, the text is changed dynamically via Java.

src/main/Java/uk/co/hassie/simpleapp/MainActivity.java

import uk.co.hassie.simpleapp.R;

public class MainActivity extends AppCompatActivity {

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

TextView textView = (TextView) findViewById(R.id.textView1);

textView.setText("Activity initialised");

}

src/main/res/layout/activity_home.xml

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">

<TextView
android:id="@+id/textView1
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Static text" />

</RelativeLayout>

I recommend that you read through the Android SDK documentation on Google's Developer Site. They provide really clear and detailed explanation with code examples.

It's the same way I learnt Android development, so I would recommend it.
