I successfully completed the EditText with the Toast message, but now all of a sudden my image does not show up.

Question

In my .xml file, I have the ImageView coded in, and visually the image is present, but it is not present in the emulator. My code for my MainActivity.java is package com.example.nvite.signalsfrommars;

import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast;

public class MainActivity extends Activity {

private EditText mNameField;
private Button mStartButton;

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

    mNameField = (EditText)findViewById(R.id.nameEditText);
    mStartButton = (Button)findViewById(R.id.button);

    mStartButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view){
            String name = mNameField.getText().toString();
            Toast.makeText(MainActivity.this, name, Toast.LENGTH_LONG).show();
        }
    });
}

}

Then, my activity-main.xml file's code is:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.nvite.signalsfrommars.MainActivity">

<ImageView
    android:id="@+id/titleImageView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:contentDescription="Signals from Mars"
    android:scaleType="fitXY"
    app:srcCompat="@drawable/main_title"
    tools:layout_editor_absoluteX="8dp"
    tools:layout_editor_absoluteY="16dp"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"/>

<Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Start your adventure!"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_marginBottom="10dp"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"/>

<EditText
    android:id="@+id/nameEditText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:ems="10"
    android:hint="Enter your name to begin"
    android:inputType="textPersonName"
    android:maxLength="30"
    android:layout_above="@+id/button"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_marginBottom="30dp"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"/>

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_below="@+id/titleImageView"
    android:layout_marginLeft="137dp"
    android:layout_marginStart="137dp"/>

</RelativeLayout>

Thanks!

Umm, somehow you got a MapView inserted into the layout that shouldn't be there (at the bottom of the layout file). As I read it the MapView is likely covering the image, so try removing the MapView.
