public class MainActivity extends AppCompatActivity {
    private ImageButton btn;
    private ImageView imageView;
    private static int RESULT_LOAD_IMAGE = 1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       btn=(ImageButton)findViewById(R.id.imageButton);
       btn.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
               startActivityForResult(i, RESULT_LOAD_IMAGE);
           }
       });
    }
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
            filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

            imageView = (ImageView) findViewById(R.id.imgView);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

        }
    }
}

//manage main.xml by yourself

Do you have any explanation on how i should implement this or what should be in my main.xml? — , Mar 22 '16 at 14:14
