How to switch between screens?

I'm new in the android develop world. I created simple application and created a simple GUI with one button. If the user presses this button, I want to change the screen to show some other GUI.

How can I do this?

A better word than "Screen" is "Activity", You switch between Activities in android.

A very simple way is to create a button on one activity (Lets call this First Activity) and assign it a method like onClick = startSecondActivity in the .xml file.

Open FirstActivity.java, Add the method startSecondActivity inside the main method as shown below. This will work!

public class MainActivity extends AppCompatActivity {

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

        // Set the content of the activity to use the activity_main.xml layout file
        setContentView(R.layout.activity_main);
    }

    public void startSecondActivity(View view){
        Intent i = new Intent(this, SecondActivity.class);
        startActivity(i);
    }
}

Another way,Button in an XML graphical layout and implement a button click listener together with an onclick method. The onclick method will start a new activity using an intent. 

<Button
    android:id="@+id/buttonClick"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:text="Button" />

Now go to your Class 

// Locate the button in activity_main.xml
    button = (Button) findViewById(R.id.buttonClick);

    // Capture button clicks
    button.setOnClickListener(new OnClickListener() {
        public void onClick(View arg0) {

            // Start NewActivity.class
            Intent myIntent = new Intent(getApplicationContext(),AddYourNewActivityName.class);
            startActivity(myIntent);
        }
    });

Hope this helps .

Set the button's onClick to a method that uses Intent.

XML:

<Button
    android:onClick="to_different_page"/>
</Button>

Java method:

public void to_different_page(View view) {
    Intent intent = new Intent(this, browse_post_activity.class);
    startActivity(intent);
}

You can do something like this: 

import android.view.View;

/** Called when the activity is first created. */
public class YourActivity extends Activity implements View.OnClickListener {

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

        Button button = (Button) findViewById(R.id.your_button_id);
        button.setOnClickListener(this);
    }

    public void onClick(View v) {
        Intent intent = new Intent(your_present_activity.this, target_activity.class);
        startActivity(intent);
    }
}

For moving from one Activity to another Activity, you need to use Intent.

For example, you are having one activity "A" contains button and second activity "B", and you want to move from "A" to "B" then write:

Intent intent = new Intent(A.this, B.class);
startActivity(intent);

Practical and informative examples for the Intent are here: Android Intents - Tutorial
