Example with ImageView.setImageResource
File conntent_main.xml:
<ImageView
android:id="@+id/imgview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="70dp"
/>
File MainActivity.java
After: public class MainActivity extends AppCompatActivity {
add
public ImageView imgview;

imgview = (ImageView) findViewById(R.id.imgview);
if (!imgview.isInEditMode()) {
imgview.setImageResource(R.drawable.logo);

We will get the result:
Example with ImageView.setScaleType
File content_main.xml
<ImageView

android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/logo"
android:layout_marginTop="70dp"
/>
File MainActivity.java
And in method onCreate add
imgview = (ImageView) findViewById(R.id.imgview);
if (!imgview.isInEditMode()) {
imgview.setScaleType(ImageView.ScaleType.FIT_START);
}
The result we will get:
